产前驱虫对母羊产奶量和乳品质的影响
|
摘要
本试验旨在研究产前驱虫对母羊产奶量和乳品质的影响。采用2×2因子试验设计,选择自然感染胃肠道线虫(GIN)的小尾寒羊(STH)和乌珠穆沁羊(UJU)母羊各20只,随机分为驱虫组和非驱虫组,驱虫组母羊于产前30 d驱虫。从产羔后开始收集羊奶样品28 d,测定产奶量和乳品质。结果显示:产前驱虫能够显著提高STH和UJU母羊的产奶量(P<0.001),但2个品种的提高程度不同,STH母羊的提高程度大于UJU母羊。此外,产前驱虫还能够显著提高羊乳的乳脂(P=0.008)、乳蛋白含量(P<0.001)及冰点(P=0.010),显著降低羊乳的体细胞数(P<0.001)、乳灰分含量(P=0.041)、pH(P<0.001)和电导率(P=0.007)。综上,产前驱虫可提高母羊的产奶量和乳品质,且产前驱虫对STH母羊的影响程度大于UJU母羊。
This experiment was conducted to study the effects of antenatal anthelmintic treatment on milk yield and milk quality of ewes.Twenty female small tailed Han sheep(STH) and 20 female Ujumqin sheep(UJU),which were naturally infected with gastrointestinal nematodes(GIN) were selected and randomly assigned to the anthelmintic group and the non-anthelmintic group according to a 2×2-factor test design.The ewes in anthelmintic group were dewormed 30 days before the expected lambing date.Milk yield was recorded from laming day and milk samples were collected to determine the composition of milk for 28 days post-lambing.The results showed that antenatal anthelmintic treatment significantly increased the milk yield of STH and UJU ewes(P<0.001),but the degree of influence between two species was different,with greater impact for STH ewes than UJU ewes.Moreover,antenatal anthelmintic treatment significantly increased the contents of milk fat(P=0.008) and milk protein(P< 0.001) and freezing point(P=0.010) of milk,while significantly decreased somatic cell count(SCC)(P<0.001),milk ash content(P=0.041),pH(P<0.001) and conductivity(P=0.007) of milk.In conclusion,antenatal anthelmintic treatment can increase milk yield and milk quality of ewes,and the degree of influence for STH ewes is greater than that for UJU ewes.
