articleAbstract=[Objective]This study aimedto investigate the changes in somatic cell count(SCC)of dairy goats across different lactation months and analyze the correlation between SCC and major milk components.[Method] In 2024,208 lactating dairy goats were randomly selected.Milk samples were collected in March,July,and October to measure SCC,as well as major milk components such as milk fat,protein,and lactose.Data analysis was conducted using SPSS software.[Result]The results showed that SCC in March was significantly lower than that in July(P<0.05).SCC had a highly significant positive correlation with milk protein(P<0.01),a positive but non-significant correlation with fat and non-fat solids(P>0.05),a highly significant negative correlation with lactose and urea nitrogen(P<0.01),and a significant positive correlation with total solids(P<0.05).[Conclusion]It is recommended to measure SCC and milk components in March as standards for assessing the quality of goat milk,which can help improve the overall quality of goat milk., authors=LIU Gang1 , SUN Qiang2 , YU Tuan3 , authorsList=LIU Gang, SUN Qiang, YU Tuan, authorCompany=1 Jimo District Animal Husbandry

头泌乳奶山羊,在3月、7月和10月分别采集乳样,检测SCC以及脂肪、蛋白质、乳糖等主要成分,用SPSS软件分析数据。[结果]3月SCC显著低于7月(P<0.05)。SCC与蛋白呈极显著正相关(P<0.01),与脂肪和非脂固形物呈正相关但不显著(P>0.05),与乳糖和尿素氮呈极显著负相关(P<0.01),与总固形物呈显著正相关(P<0.05)。[结论]建议在3月测定SCC和乳成分,作为评估羊乳品质的标准,有助于提升羊乳的整体品质。,

[目的]探讨奶山羊不同泌乳月份体细胞数(SCC)变化,分析SCC与主要乳成分之间的相关性。[方法]2024年随机选取208 头泌乳奶山羊,在3月、7月和10月分别采集乳样,检测SCC以及脂肪、蛋白质、乳糖等主要成分,用SPSS软件分析数据。[结果]3月SCC显著低于7月(P<0.05)。SCC与蛋白呈极显著正相关(P<0.01),与脂肪和非脂固形物呈正相关但不显著(P>0.05),与乳糖和尿素氮呈极显著负相关(P<0.01),与总固形物呈显著正相关(P<0.05)。[结论]建议在3月测定SCC和乳成分,作为评估羊乳品质的标准,有助于提升羊乳的整体品质。

[Objective]This study aimedto investigate the changes in somatic cell count(SCC)of dairy goats across different lactation months and analyze the correlation between SCC and major milk components.[Method] In 2024,208 lactating dairy goats were randomly selected.Milk samples were collected in March,July,and October to measure SCC,as well as major milk components such as milk fat,protein,and lactose.Data analysis was conducted using SPSS software.[Result]The results showed that SCC in March was significantly lower than that in July(P<0.05).SCC had a highly significant positive correlation with milk protein(P<0.01),a positive but non-significant correlation with fat and non-fat solids(P>0.05),a highly significant negative correlation with lactose and urea nitrogen(P<0.01),and a significant positive correlation with total solids(P<0.05).[Conclusion]It is recommended to measure SCC and milk components in March as standards for assessing the quality of goat milk,which can help improve the overall quality of goat milk.
