In Sudan, many Butana cattle farmers practice indiscriminate crossbreeding to improve the milk yield performance of cows, as organized breeding programs are lacking. Objectives of this study were to identify the current production conditions of Butana cattle and to determine farmers' production objectives and trait preferences using a field survey. The overall aim was to explore the possibility of establishing a community-based breeding program for the genetic improvement of the breed. A semi-structured questionnaire and field visits were used to collect data from 202 Butana cattle owners. Data were analyzed using chi-squared test, multiple response analysis, and binary logistic regression. Our results showed that Butana cattle farmers mainly raised their animals for milk production. On a five-point scale (5 = most important), milk yield (4.6 ± 0.05), growth performance (4.0 ± 0.07), and lactation length (3.9 ± 0.08) were highly preferred for future development of the breed. One-third of the farmers kept crossbred cattle with on average 4 crossbred animals per herd. About two-thirds of respondents were willing to adopt crossbreeding using exotic breeds to increase milk performance and about the same proportion were willing to exchange breeding bulls and establish farmers' associations. None of the respondents kept written performance records. However, educated farmers were more likely to adopt record keeping. Farmers' willingness to engage in associations could be useful for the establishment of a community-based breeding program. Based on the current farmers' production objectives, the future breeding program should emphasize increasing milk production of the Butana cattle by using improved Butana bulls in village herds.
在苏丹,许多布塔纳牛养殖户为了提高奶牛的产奶性能而进行随意杂交,因为缺乏有组织的繁殖计划。本研究的目的是确定布塔纳牛的当前生产状况,并通过实地调查确定农民的生产目标和性状偏好。总体目标是探索为该品种的遗传改良建立基于社区的繁殖计划的可能性。采用半结构化问卷和实地访问的方式,从 202 名布塔纳牛养殖户收集数据。使用卡方检验、多响应分析和二元逻辑回归分析数据。结果表明,布塔纳牛养殖户主要将其动物用于产奶。在五分制(5=最重要)中,产奶量(4.6±0.05)、生长性能(4.0±0.07)和泌乳期(3.9±0.08)被高度认为是该品种未来发展的重要因素。三分之一的养殖户饲养了与平均每群 4 头杂交牛的杂交牛。大约三分之二的受访者愿意采用杂交方式利用外来品种来提高产奶性能,同样比例的受访者愿意交换种公牛并建立养殖户协会。没有受访者保留书面的性能记录。但是,受过教育的农民更有可能保留记录。养殖户参与协会的意愿对于建立基于社区的繁殖计划可能很有用。根据当前养殖户的生产目标,未来的繁殖计划应强调通过在村群中使用改良的布塔纳公牛来提高布塔纳牛的产奶量。
