摘要

在2020年产羔季节之前,147名威尔士农民通过培训和讨论小组积极参与初乳管理。其中64位农民返回了1295只母羊的数据,包括母羊的年龄、品种、身体状况评分(BCS)、出生的活羊和死羊的数量、乳房状况的描述、初乳的颜色和Brix读数。从43个养殖场获得了畜群数量,从30个养殖场获得了妊娠后期口粮信息。使用Brix读数截断值26.5%对结果进行分析,结果显示76%的样本超过了这一水平,被认为质量良好。平均每群返回20份母羊初乳样品,发现在羊群水平上变化最大,母羊营养被认为是最大的驱动因素。精料饲料空间、青贮粗蛋白质和精料对双胎和三胞胎母羊的补充量都是影响初乳品质的潜在群体水平因素。母羊个体水平的因素在决定初乳质量方面的作用似乎要小得多,易剥性是主要的显著因素。如果母羊被报道难以剥离,则初乳质量更有可能不足(OR 0.56)。虽然在最终回归模型中不显著,但其他母羊因素似乎对初乳质量有影响,如BCS和出生羔羊数;然而,模型中缺乏显著性可能意味着它们不重要,或者它们反映了不同禽群之间管理的差异。随着英国牧羊户为2022年羔羊生产做准备,并继续优化初乳管理和减少给新生羔羊的抗生素水平,这项实际研究表明,牧羊户如何积极主动地测量初乳质量,以确定如何优化管理初乳抗体给每只羔羊的输送。

Ewe colostrum quality on commercial Welsh sheep farms
In advance of the 2020 lambing season, 147 Welsh farmers were engaged in active colostrum management through training and discussion groups. Sixty-four of these farmers returned data on 1295 ewes, including ewe age, breed, body condition score (BCS), number of live and dead lambs born, a description of udder condition, colour of colostrum and a Brix reading. Flock numbers were available from 43 farmers and information on late pregnancy ration from 30 farms. Results were analysed using a Brix reading cut-off of 26.5% and showed that 76% of samples exceeded this level and were considered of good quality. With an average of 20 ewe colostrum samples returned per flock, the greatest variation was found to be at the flock level with ewe nutrition considered to be the greatest driver. Concentrate feed space, silage crude protein and the supplementation of concentrates to twin and triplet-bearing ewes were all factors that indicated a potential flock level role in determining the colostrum quality. Individual level ewe factors appeared to have a much smaller role in determining the quality of the colostrum, with the ease of stripping being the main significant factors. Colostrum quality was more likely to be inadequate if the ewe was reported to be hard to strip (OR 0.56). While not significant in the final regression model, other ewe factors appeared to have an impact on the colostrum quality, such as the BCS and number of lambs born; however, lack of significance in the model may mean they are not significant or that they reflect differences in management between different flocks. As UK sheep farmers prepare for lambing 2022, and continue to optimise colostrum management and reduce levels of antibiotic given to neonatal lambs, this practical study has demonstrated how sheep farmers can be actively motivated to measure colostrum quality to determine how to optimally manage colostral antibody delivery to individual lambs.
