Abstract

To improve productivity, dairy producers are increasingly seeking to improve the productive efficiency of the herd. Therefore, the present study was carried out on a private property in the city of Santo Anastácio, in the region of Presidente Prudente/SP (Brazil), characterized by a milk production system in more concentrated pasture, with supplementation of roughage for the animals in the winter months. 16 lactating cows of the Holstein, Girolanda and crossbred breeds (average weight of 480 kg) were used. The objective of this work was to evaluate the effect of adding Promixalicin to the diet on the behavior of lactating cows, and on the SCC (Somatic Cell Count) of the animals' milk. The animals were analyzed for 180 days, but Promyxalicin was supplied from the 61st to the 120th experimental day. Animal behavior was observed in relation to head and tail shaking, and animal restlessness due to attacks by ectoparasites (Haematobia irritans, Stomoxys calcitrans and ticks). Monthly SCC measurements were taken of the animals' milk in the first week of each month, throughout the experimental period. It can be inferred that, on the day the Promyxalicin supply began (day 61), the animals showed many stress behaviors such as tail wagging, head shaking and restlessness. Its benefits were significant from the 7th day after using the product (67th day), implying its efficiency for the evaluation of ticks on animals. 15 days after the start of supplying the product (75th experimental day), there was a significant reduction in the number of ticks remaining on the animals. Regarding SCC, the use of Promyxalicin proved to be effective as it significantly improved the animals' SCC within just 30 days of using the product.  The use of Promyxalicin for lactating cows improved animal well-being due to the repellence of ectoparasites, and significantly reducing the SCC of the milk, indicating an improvement in animal performance, mainly due to the improvement of conditions for increased milk production.
评估饲喂丙沙利嗪的奶牛的SCC和行为表现
为了提高生产率,奶制品生产商越来越多地寻求提高牛群的生产效率。因此,本研究在巴西普鲁登特总统地区圣阿纳斯塔西奥市的一处私人农场进行,该农场的特点是在较为集中的牧场上进行牛奶生产,并在冬季为动物补充粗饲料。使用了 16 头荷斯坦、吉罗兰达和杂交品种的泌乳奶牛(平均体重 480 千克)。这项工作的目的是评估在日粮中添加普罗米沙利钦对泌乳奶牛的行为和牛奶中体细胞数(SCC)的影响。对动物进行了为期 180 天的分析,但从第 61 天到第 120 个实验日都添加了原沙拉秦。对动物的行为进行了观察,包括摇头和摇尾,以及因受到体外寄生虫(Haematobia irritans、Stomoxys calcitrans 和蜱)的攻击而产生的躁动不安。在整个实验期间,每个月的第一周都会对动物的乳汁进行 SCC 测量。可以推断,在开始供应丙沙利嗪的当天(第 61 天),动物表现出许多应激行为,如摇尾、摇头和烦躁不安。从使用该产品后的第 7 天(第 67 天)开始,其效果就非常明显,这意味着该产品在评估动物身上的蜱虫时非常有效。开始使用该产品 15 天后(第 75 个实验日),动物身上残留的蜱数量显著减少。在 SCC 方面,事实证明使用 Promyxalicin 是有效的,因为在使用该产品的短短 30 天内,动物的 SCC 就得到了明显改善。 对泌乳奶牛使用 Promyxalicin 可驱除体外寄生虫,从而改善动物的健康状况,并显著降低牛奶的 SCC,这表明动物的生产性能得到了改善,这主要是由于改善了提高产奶量的条件。
