Livestock Production Challenges and Improved Forage Production Efforts in the Damot Gale District of Wolaita Zone, Ethiopia

(is study was conducted to identify major livestock production constraints and improved forage production efforts in the Damot Gale district. Four representative kebeles, two associated with our NGO project and two from nonproject outreach activities, were selected. Forty farmers from each kebele were randomly chosen for the purpose of individual interviews using a semistructured questionnaire. Data collected were analyzed using SPSS (version 20) and Excel.(e topmost livestock production constraint was feed shortage where a larger proportion of farmers (75.6%) suffered from the problem with higher (p≤ 0.01) severity in nonproject intervention areas. Of these, 38.6%were challenged for a period of threemonths while another 61.4% suffered for about fourmonths. Purchasing grass (31.4%) and concentrate (33.5%) and feeding enset (Ensete ventricosum) leaf (21.49%) were the most commonly adopted copingmechanisms to alleviate feed shortages during the dry season, while using purchased grass and enset leaf was themain coping strategy in nonproject intervention (p≤ 0.01) areas. (e majority of households (90.75%) participate in improved forage production regardless of farm size. Desho grass (Pennisetum pedicellatum) (71.38%) and elephant grass (Pennisetum purpureum) (42.63%) are the most common improved forages in both study areas. (ese forages are produced for the purpose of two or more functions (feed, cash, and preventing erosion) that vary (p≤ 0.01) among intervention status. Major niche locations adopted for improved forage production include farm land, soil andwater conservation structures, and perimeter fencing. Greatest constraints on improved forage production were seed/material shortage followed by land shortage and lack of awareness. Project intervention (p≤ 0.01), tropical livestock unit (TLU) holding (p≤ 0.01), and forage seed/planting material access (p< 0.05) were identified as factors (among others) having significant relationship with improved forage development. Strong extension services and efficient input delivery for farmers are vital to support profitable livestock production and resource utilization.


Introduction
Livestock production is a crucial component of agriculture that can support livelihoods and food security of large numbers of people in developing world. Likewise, this sector plays a significant role in income generation, food and nutrition security, draught power and source of manure for about 85% of rural populations who depend largely on livestock and crop production systems in Ethiopia. About 15 to 17% of the gross domestic product (GDP) and 37 to 87% of household incomes are contributed from the overall livestock sector, including ruminant and nonruminant production [1,2].
Ethiopia has a large livestock population, with an estimated 60.39 million cattle, 31.3 million sheep, 32.74 million goats, 11.32 million equines, and 1.42 million camels [3]. Despite the large number and importance of these animals, their productivity is low due to a number of factors such as inefficient management, poor infrastructure, poor marketing and credit facilities, feed shortages both in quality and quantity, and health constraints [4][5][6]. Among these, shortage of feed was identified as one of the primary constraints in livestock production [7]. One of the recommended profitable options to address this challenge is improved forage production using strategies suitable for a given farming system [8].
e objective of this study was therefore to identify major livestock production challenges and improved forage production strategies for feed-related constraints in the study areas. e output will be utilized by different research and development stakeholders to design production and resource utilization strategies to overcome existing constraints.

Description of the Study Area.
Damot Gale is one of the districts of the Wolaita zone in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia within the coordinates of 6°53′0″ and 7°6′30″N and 37°46′0″ and 37°58′ 40″E [9] with an altitude range of 1612-2964 m.a.s.l. It is located in the east Rift valley at a distance of 370 km to the south of Addis Ababa and at about 140 km to the west of Hawassa, which is the capital city of Southern Nations Nationalities and Peoples Regional State (SNNPR). e district has an area of 410.1 km 2 with a human population of 151,079 [10]. e district has two major agroecology regions, Highland (26%) and Midland (74%), with annual rainfall in the area ranging from 900 mm to 1400 mm with minimum and maximum temperatures of 12°C and 25°C [11]. e administrative center of Damot Gale is Boditi shown in Figure 1.

Research Design, Sampling, and Data Collection
Procedures. Descriptive research design was used for this study. After consultation and discussion with concerned officials about the objective of the study, four representative kebeles (two from our NGO project intervention and two nonintervention areas) were selected based on road accessibility. Eighty farmers (40 from each kebele) were randomly selected from each study area (project intervention and nonproject intervention), out of the model farmers (who actively engage on different community-based activities) for the purpose of individual interviews (by considering the two representative kebeles as one unit). A total of 160 households were selected using the sample size formula, n � (N/(1 + N(e 2 ))) [12]. Simple random sampling technique, using random number generator, was used to select individual farmers. Margin of error (maximum variability) of 5% was considered. Key informant interviews were conducted with experts from the district and the study kebeles. Secondary data were also reviewed from previous district reports, journals, and proceedings. Data collected included socioeconomic characteristics, major livestock production constraints, improved forage types produced, forage seed sources, and forage production niches.

Data Analysis.
Following the completion of field data collection, data were coded, organized, summarized, and analyzed using Statistical Package for the Social Sciences (SPSS version 20). Descriptive statistical analysis was conducted through custom table. Binary logistics regression analysis was carried out to determine the effect of project intervention, household characteristics, resource holding, and input provision (independent variables) on efforts of improved forage production (dependent variable). Index was calculated using the following formula with MS-excel package.
where N � maximum level of rank, F1 � frequency of the 1 st rank, F2 � frequency of the 2 nd rank, and Fn � frequency of last rank. Model equation for logistic regression analysis is as follows: where Y � dependent variable (existence of forage production), a � constant, β � coefficient of the predictor variable, PI � project intervention, G � gender variable, E � education level, AFM � active family member, LH � land holding, TLU � tropical livestock unit, FSA � forage seed access, and € � error term.

Livestock and Land
Holding. Livestock and land holdings in the project intervention and nonintervention areas are presented in Table 1. Almost all farmers possess livestock regardless of number and species. Among the class of ruminant animals, sheep (2.56) holding was the highest followed by cow (1.68) and calf (1.65). Chicken were common in both study areas. Sheep account for the major small ruminant holding. Possession of equine was almost negligible. Average land holding is below one hectare with no significant variation among farmers in project intervention and nonproject intervention areas. Table 2 shows the different livestock production challenges identified in the study area. e major constraints in both project intervention and nonintervention areas include feed shortage, water shortage, disease, market problems, and poor breed performance. Feed shortage was the primary constraint in both areas. Water, which ranked 3 rd among constraints in the nonproject intervention area, is the second most important constraint in the project intervention. Disease problems scored 3 rd and 2 nd in project intervention and nonintervention areas, respectively. Constraints related to market and production performance are ranked fourth and fifth in respective order.

Livestock Feed Shortage and Coping Mechanisms.
Percentages of farm households with feed shortage, time of shortage, and coping mechanisms are presented in Table 3.    N is the sum of the products of frequency and score and is obtained by adding the multiplication of the frequency and score given for each rank level. e 1 st rank level is given the highest score (5). e majority of farmers (75.6%) at the district level suffered from feed shortages. Significantly higher number of farmers (p ≤ 0.01) in nonproject intervention areas faced this challenge as compared to nonintervention areas. Among those farmers with a feed shortage problem, about 98.68% faced this challenge during the dry season of the year (February-May). Out of these, 38.6% were challenged for a length of three months (from March to May) while others 61.4% suffered for about four months (February to May) with significant variation (p ≤ 0.01) between intervention status. Farmers practiced different coping mechanisms, like feed purchasing feed and feeding enset (Ensete ventricosum) to alleviate the feed shortage problem. Purchasing grass is the most-adopted coping mechanism in the nonproject intervention area (p ≤ 0.01) while purchasing concentrate is used most in project intervention areas.

Seasonal Feed Availability.
e seasonal availability and utilization of existing feed resources are presented in Table 4. Crop residues, enset, hay, and concentrate are the major feed resources available and utilized during the dry season in both project intervention and nonintervention areas. In wet seasons, harvested local grass (fresh grass for cut and carry feeding), grazing, and collected fodders (weeds and leaves from different herbs and shrubs) are the major available feeds and are frequently utilized. Dependency on grazing is significantly higher (p ≤ 0.01) in nonproject intervention than intervention areas while harvested local grass was more available (p ≤ 0.01) in project intervention than nonintervention areas during wet periods. Improved forages were available and utilized in both the dry and wet seasons of the year with significant variation (p ≤ 0.01) among intervention and nonintervention areas. e majority of the respondents indicated that there is no problem with concentrate feed availability in both the dry and wet seasons of the year regardless of the cost ( Figure 2).

Improved Forage Production Status.
Use of improved forage and the major forage types produced in the study areas is presented in Table 5. A large proportion of farmers (90.75%) in both the project intervention and nonintervention areas have experience on producing improved forages, particularly Desho grass (Pennisetum pedicellatum) (71.38%) and elephant grass (Pennisetum purpureum) (42.63%) which are most common in the study area. In the project intervention area, Desho grass (99%) is most common, and in the nonproject intervention area, elephant grass (66.25%) is produced by most farmers. In project intervention areas, oat-vetch mixed forage and Guatemala grass (Tripsacum andersonii) are newly introduced forage species.
3.6. Purpose of Improved Forage Production. Farmers produce improved forages as a source of cash, for use as feed, for preventing erosion, or for two or more of these functions (Table 6). e majority of the farm households produce forage for more than one function. Most farmers (p ≤ 0.01) in project intervention areas produce Desho grass for more than two purposes (as a source of feed and cash and for preventing erosion). In contrast, a larger proportion of farm households (p ≤ 0.01) in nonproject intervention areas produced improved forages mainly targeted only for two purposes (feed and preventing erosion). Elephant grass production is mainly targeted for feed and prevention of erosion.

Forage Seed/Planting Material Availability.
Farmers with forage seed/planting material access, forage seed providers and available forage seed/planting materials are indicated in Table 7. e majority of farm households have access to improved forage seed/planting material in project intervention compared to nonintervention areas (p ≤ 0.001). Desho grass planting material was more accessible (99%) than elephant grass (15%) in project intervention areas and the reverse is true in nonproject intervention areas. e forage seed/planting material transfer system is free except in a few cases when farmers purchase from other individuals. Inter Aid and "Send a Cow" (nongovernmental organizations) were the main providers of Desho and elephant grass seed/planting material in the project intervention area, whereas the District Office of Agriculture was the main provider in the nonproject intervention area.

Niches Adoption and Land Allocation for Improved Forage
Production.
e percent of farmers who allocate cultivated land to forage production and the niches used for improved forage production are given in Table 8. Major niche types adopted for improved forage production include farm land and soil and water conservation structures and around fences. More farmers (p ≤ 0.01) in the project intervention area allocate land (of different niches) for forage production more than farmers in the nonproject intervention area. Likewise, relatively more (p < 0.05) farm land area is allocated for forage production in project intervention areas.

Constraints for Improved Forage Production.
Major constraints that hampered improved forage production are presented in Table 9. Shortage of improved forage seed/ planting material was the primary constraint followed by land shortage and lack of awareness. A significantly higher proportion of farmers (p ≤ 0.01) in nonproject intervention areas faced a planting material shortage than those in project intervention areas, whereas the number of farmers constrained by land shortage was higher (p ≤ 0.01) in project intervention than in nonproject areas.

Logistic Regression Analysis for Selected Determinant
Variable on Forage Production. Significant determinant factors for effective forage development in the study district are presented in Table 10. Based on the result of binary logistic regression analysis, project intervention (p ≤ 0.01), tropical livestock unit (TLU) holding (p ≤ 0.001), and forage seed/planting material access (p ≤ 0.05) were identified as factors (among others) having significant relationship with improved forage development. e likelihood of improved forage production practice in project intervention areas was 92.265 times higher than nonproject intervention sites. Farmers with higher TLU holding were 26.993 times more likely to produce improved forage compared with those households with lower TLU holding. On the other hand, better seed/planting material access increased the likelihood of improved forage development by 11.983 times.

Livestock and Land Holding.
ere were no significant differences in livestock holdings between project intervention and nonintervention areas. Ruminant animal holdings in the current study were similar to reports for the Anelemo district of Hadiya zone, SNNPR [13]. Average total livestock kept by individual households in the current study is lower than reports in another area [14]. is could be due to the limited availability of feed resources [15].        Advances in Agriculture e total average land holding per household in both of the target study areas was similar to reports for average land holdings for the Doyogena district (0.5-1 ha) [16]. However, the land holding size in the current study was lower than a report for other areas [14,17]. is indicates that improved land use planning and forage development strategies need to be intensified to improve forage production within the existing land resource and production system.

Livestock Production Challenges.
Feed shortage, which was identified as a primary constraint, was attributed to unwise feed resource utilization, low forage production, and limited forage species diversification. Water shortage problems could be related to existing infrastructure and technical gaps in the wise use of available water resources as well as poor water harvesting techniques. Disease constraints could be attributed to poor veterinary services and poorly developed technical skills. Market problem could be related to the seasonal inconsistencies of market demand for animal and animal products. Animal breed performance problems could be associated with lack of progress in breed improvement programs. ese problems were in line with reports on the Horro and Guduru districts [18]. Consideration of breed performance is the least important problem according to the majority of the farmers. Livestock breed performance problems with lower priority indicate untapped productive potential of local breeds in the presence of good management practices, such as proper feeding, selection for best traits, health care, and all other necessary husbandry practices. Moreover, local breeds are resistant to disease and can perform better under limited feed availability and less intensive management conditions [6,19,20].

Livestock Feed Shortage and Coping Mechanisms.
As per the result of the current study, a large proportion of farm households in both areas suffered from livestock feed shortages with significantly higher severity in nonproject intervention than intervention areas. e main period with livestock feed deficiency in the study area started at the end of January and continued to the beginning of May which is   in line with reports for the highland of Ethiopia [21]. e feed shortage problem during the dry season in the study area is related to moisture stress that resulted in low herbage growth on existing grazing land [22]. Moreover, crop residues which are serving as the main source of roughage feed during the dry season [13,23] are low in nutrient content [24]. Many farmers rely on purchased roughage and concentrate, and enset feeding in response to the existing feed shortage.

Seasonal Feed Availability.
Regardless of the biomass, most farmers in both project intervention and nonintervention areas use improved forages in both the dry and the wet season. During the dry period, there is a feed shortage of green feeds, also a common problem in other areas of the country [21]. Crop residues that are poor in nutritive value [25] and hay, to some extent, are the major feed resource used during the dry season in the study area, with a similar pattern in other areas [13]. Nevertheless, there were farmers who use improved forages during the dry season of the year. is trend was in agreement with reports from other areas in which farmers used improved forage during dry periods [13,26]. is indicated that improved forages are playing a big role in covering the gap of green feed supply during dry periods. Availability of high-protein feeds like legume forages is negligible. is situation requires intensification and expanded availability of improved forages using innovative production strategies and niches.

Improved Forage Production Status.
Desho grass was the most dominant improved forage species adopted in the study area. It was also reported as a common improved forage in other areas in the region [13,16,26,27]. is situation calls for additional effective training and related extension services to inform and encourage farmers about efficient production and utilization systems for this grass.
ere were few attempts to introduce legume forages and develop management strategies, a subject that needs attention by development and research practitioners in order to increase high-protein feeds in the district.
Improved forage production could be used to overcome feed shortages but is constrained by many challenges including small land holdings, priority given to food crop production, lack of forage seeds, and limited knowledge on forage species and their production systems. is situation was exacerbated by the absence of an improved forage seed provision and transfer system in the area. is requires the attention of concerned stakeholders to design sustainable forage seed transfer systems. In contrast to a report for the Anelemo [13] and Robi districts [28], in which land was the primary constraint, in the current study area, a forage seed/ planting material shortage was the primary constraint followed by land shortage and a lack of training and information.

Purpose of Forage Production.
e objective of improved forage production that can serve a multiple role in the study area is consistent with the results reported for the Shashego district of the Hadiya zone [26]. Improved forage production can help boost feed availability and improve crop productivity by conserving soil and water [29,30]. e limited roles (feeding and erosion only) of forage production in nonproject intervention areas could be related to the lower availability and less intensive production of improved forages. As a result, the forage produced was not abundant enough to provide an excess for sale. Improved forage production can serve as a source of cash in addition to other roles provided that there is sufficient production.

Forage Seed/Planting Material Availability.
ough nongovernmental organizations and government extension system are responsible for the distribution of suitable improved forage technologies for farming communities, there is still limitation in the available varieties of forages, especially varieties of legume species. is situation needs special attention by research and development organizations in order to intensify varieties of improved forages to improve the existing agricultural system. e relatively better distribution and availability of forage planting material in the project intervention area could be attributed to sufficient resources and effective utilization of those resources while addressing the technology used by the farmers with an effective monitoring system.

Niches Adopted and Land Allocation for Forage
Production. Forage production niches adopted in the area were similar to reports for the Doyogena district of the Kembata-Tembaro zone, where terrace plantations were the most common type [31]. Larger areas of farm land allocation for forage production by a majority of the farmers in project intervention areas may be related to better provision of seed/ planting material and better adoption of improved forages for their multiple roles including as a source of cash. is indicated that choice of niches in the study area depends on the availability of planting material and the level of production [32,33] rather than farm land size which was not consistent according to a report by Njarui et al. [34]. Moreover, larger farm land allocations of a greater number of farmers in the project intervention area indicated a strong interest of farmers for improved forage production if they are provided planting material with necessary training on production and utilization systems.

Constraints of Improved Forage Production.
e higher number of farmers experiencing a forage planting material shortage in the nonproject intervention area could be attributed to the limited forage seed supply [31]. In contrast, the higher number of farmers with a land shortage problem in the project intervention area could be attributed to more production of improved forage grass that took additional land. is indicated that improved forage production might result in land competition for food crop production. Lack of awareness of alternative improved forages and their production strategies hampered the scaling up of improved 8 Advances in Agriculture forage technologies more than the shortage of land and improved forage seeds. Hence, this situation needs attention to improve the application of different forage development strategies and the introduction of legume forages that can be integrated with other cropping systems.

Logistic Regression Analysis for Selected Determinant
Variable on Forage Production. Among household, farming, and project characteristics, only project intervention, tropical livestock unit (TLU) holding, and access to forage seed/planting technology were the significant factors affecting the likelihood of improved forage production in the district. e significantly higher rate of forage production in project intervention is attributed with proper input (forage technology) provision, efficient training, and continuous follow-up as compared to nonproject intervention. is indicates that, though land shortage is mentioned as a common constraint, farmers are interested to develop forage on different strategies if they are provided with the required forage technology and effective training (linked with proper monitoring) on improved forages development and utilization techniques, which is inconsistent with other reports [26,35]. Farmers with higher livestock holding, especially dairy cow and draught oxen, were more promoted to produce improved forage which is in line with another report [27]. is could be associated with the intention of farmers to produce more milk and butter, and oxen draught power through better supplementation. e household characteristics (gender, education level, and family size) in the current study did not show significant relationship with improved forage production. is could be attributed to allocation of more labor force for activities other than forage production. Level of education in the current study did not have significant effect on the development of improved forage technology. is could be because some people with more education level seek other nonfarm income source activities in nearby towns.

Conclusion
e top most livestock production challenge in the study area was feed shortage, which commonly occurred from February to May, with higher severity in nonproject intervention areas. Feeding of enset leaf, purchased grasses, and concentrates (mainly wheat bran) were the main coping strategies against feed shortage. Improved forage production, although it would compete for land with food crop production, can make a significant contribution to narrowing the seasonal livestock feed gap, facilitating soil and water conservation, and generating cash income.
Desho grass and elephant grass are the major improved forages introduced in the area which have been serving as the major components of livestock diets and as a cash source (especially Desho grass) in both the dry and wet seasons of the year. Distribution of forages with a significant protein concentration is poor as a result of limited improved forage technology distribution and transfer systems. Forage varieties suitable for the existing agroecology and production systems, especially legumes, need to be distributed to farmers.
A sustainable improved forage seed/planting material transfer system needs to be developed, and strong awareness of improved forage varieties needs to be created. Optimal production and utilization systems as well as efficient animal husbandry practices and proper resource utilization need to be given attention by research and development stakeholders to ensure sustainable forage technology adoption and profitable livestock production. Better efforts observed in the NGO project intervention areas are indicated as an opportunity for government organizations to share best management practices.
