【摘要】：本试验旨在研究饲粮磷水平对崂山奶山羊泌乳性能和血清生化指标的影响。选择体重(56.55±1.17)kg、产奶量(2.20±0.07)kg/d、泌乳中期的2胎健康崂山奶山羊30只,采用单因素随机分组设计,随机分成3组,每组10只,每只羊为1个重复。各组饲喂能量和蛋白质水平基本一致,磷水平分别为0.26%、0.36%及0.46%的饲粮。预试期15 d,正试期60 d。结果表明:1)饲粮磷水平对干物质采食量均无显著影响(P0.05)。2)0.36%组产奶量全期平均值较高,极显著高于0.26%组、0.46%组(P0.01),0.26%组与0.46%组差异不显著(P0.05);干物质采食量/产奶量、干物质采食量/4%标准乳产量均以0.36%组较低,极显著低于0.46%组(P0.01)。3)饲粮磷水平对乳脂率、乳蛋白率、乳糖率、乳非脂固形物率、乳磷含量、乳钙含量均无显著影响(P0.05)。4)饲粮磷水平对血清中钙、磷、尿素氮含量及碱性磷酸酶活性均无显著影响(P0.05)。由此可见,泌乳期崂山奶山羊饲粮磷水平以0.36%为宜。
[Abstract]:The purpose of this experiment was to study the effect of dietary phosphorus level on lactating performance and serum biochemical indexes of Laoshan dairy goats. The body weight of Laoshan dairy goats was 56.55 卤1.17 kg / kg, the milk yield was 2.20 卤0.07 kg / d, and 30 healthy Laoshan milk goats of middle lactation period were selected. They were randomly divided into 3 groups, 10 in each group, and each sheep was repeated. The levels of energy and protein in each group were basically the same. The phosphorus levels were 0.26% and 0.36% and 0.46%, respectively. The results showed that the dietary phosphorus level had no significant effect on the dry matter intake in 15 days and 60 days. The results showed that the average value of milk yield was higher in the groups of 0.36% and 0.36% respectively, and the results showed that there was no significant effect on the dry matter intake in the groups of 0.26% and 0.36%, respectively. There was no significant difference between group 0.26% and group 0.46%, but the dry matter intake / milk yield, dry matter intake / milk yield per 4% standard milk yield were lower in group 0.36%, and significantly lower than those in group 0.46% (P 0.01 路3), the milk fat rate, milk protein rate, lactose rate were significantly lower than those in 0.26% group (0.46%) and 0.46% group (P < 0.05). There was no significant effect of dietary phosphorus level on serum calcium, phosphorus, urea nitrogen and alkaline phosphatase activity. The appropriate dietary phosphorus level for Laoshan dairy goats during lactation was 0.36%.
