Smallholder dairy production is increasingly becoming popular in Jimma town. However, feed shortage is a major constraint to dairy production. The objectives of this study was to assess feed resources, feeding practices and farmers' perceived causes of feed shortage and coping strategies to feed scarcity in smallholder dairy producers in Jimma town, Oromia Regional State, Ethiopia. A total of 54 randomly selected dairy farmers were interviewed using a pre-tested structured questionnaire and through direct observations. Twenty major feed types used by dairy farmers were identified and categorized into five classes: natural pasture grazing, green feeds, hay, concentrate (commercial mix and agro-industrial by-products) and non-conventional feed resources. Green feeds-fresh or succulent grasses and legumes (mean rank = 0.361), concentrate (0.256), hay (0.198), non-conventional feeds (0.115) and natural pasture grazing (0.070) were ranked as the main feed resources in that order of importance. Green feed (94.4 % of the respondents) was found to be the main basal diet of dairy cattle. Overall, wheat bran (85.2 % of the respondents), commercial concentrate (55.6 %), noug (Guizotia abyssinica) cake (20.4 %), cotton seed cake (7.4 %) and molasses (7.4 %) were the main concentrate supplements used (P > 0.05). Local brew waste (attela) (77.8 % of the respondents), bean and pea hulls (42.6 %) enset (Ensete ventricosum) leaf and pseudo-stem (37 %), sugarcane tops (33.3 %), banana leaf and stem/stover (16.7 %) and papaya stem (16.7 %) were the dominant non-conventional feed resources in the surveyed area (P > 0.05). About 79.6, 7.4, 1.9 and 11.1 % of the farmers used zero-, semi-zero-, and the combination of zero- and semi-zero- and free-grazing systems, respectively. Most farmers (90.7 %) offered concentrate supplements to milking cows. However, supplementation did not consider milk yield, physiological status and condition of cows. All the farmers (100 %) offered common salt to their cattle as mineral supplement. The majority (98.1 %) of the farmers experience feed shortage in the dry season. Land scarcity (55.6 % of the respondents) was reported as the most important cause of feed scarcity followed by a combination of land scarcity and poor feed availability (42.2 %). Increasing use of agro-industrial by-products and commercial concentrate mix (87 % of the respondents), increasing use of hay (74.1 %), increasing use of non-conventional feeds (50 %), purchasing green feeds (19.8 %) and reducing herd size (2.7 %) were the strategies adopted for coping with feed scarcity. From results of this study, it could be concluded that to ensure sustainable availability of dairy cattle feed in the surveyed area, technological, technical and institutional innovations would be vital.
小农奶牛养殖在吉姆马镇越来越受欢迎。然而,饲料短缺是奶牛养殖的主要制约因素。本研究的目的是评估埃塞俄比亚奥罗米亚州吉姆马镇小农奶牛养殖户的饲料资源、饲养方式、农民认为的饲料短缺原因以及应对饲料短缺的策略。使用预先测试的结构化问卷并通过直接观察,共对54名随机选择的奶农进行了访谈。确定了奶农使用的20种主要饲料类型,并将其分为五类:天然牧场放牧、青绿饲料、干草、精饲料(商业混合料和农工业副产品)和非常规饲料资源。青绿饲料——新鲜或多汁的禾本科和豆科植物(平均排名=0.361)、精饲料(0.256)、干草(0.198)、非常规饲料(-0.115)和天然牧场放牧(0.070)按重要性顺序被列为主要饲料资源。青绿饲料(94.4%的受访者)被发现是奶牛的主要基础日粮。总体而言,麦麸(85.2%的受访者)、商业精饲料(55.6%)、诺格(Guizotia abyssinica)饼(20.4%)、棉籽饼(7.4%)和糖蜜(7.4%)是主要使用的精饲料补充剂(P>0.05)。当地酿造废料(attela)(77.8%的受访者)、豆类和豌豆壳(42.6%)、埃塞俄比亚香蕉(Ensete ventricosum)叶和假茎(37%)、甘蔗梢(33.3%)、香蕉叶和茎/秸秆(16.7%)以及木瓜茎(16.7%)是调查区域内主要的非常规饲料资源(P>0.05)。分别约有79.6%、7.4%、1.9%和ll.l%的农民采用零放牧、半零放牧、零放牧与半零放牧相结合以及自由放牧系统。大多数农民(90.7%)会给泌乳奶牛提供精饲料补充剂。然而,补充饲料时并未考虑奶牛的产奶量、生理状态和体况。所有农民(100%)都给牛提供食盐作为矿物质补充剂。大多数(98.1%)农民在旱季经历饲料短缺。土地稀缺(55.6%的受访者)被报告为饲料短缺的最重要原因,其次是土地稀缺和饲料供应不足共同作用(42.2%)。增加农工业副产品和商业精饲料混合料的使用(87%的受访者)、增加干草的使用(74.1%)、增加非常规饲料的使用(50%)、购买青绿饲料(19.8%)以及减少牛群规模(2.7%)是应对饲料短缺所采用的策略。从本研究结果可以得出结论,为确保调查区域内奶牛饲料的可持续供应,技术、技术和制度创新至关重要.
