摘  要:
以2213头成年乳肉兼用牛产奶量纪录和558个乳样的乳脂测定结果为基础材料,对四川乳肉兼用牛的泌乳性能进行了初步分析。结果表明,四川乳肉兼用牛的各胎次泌乳量为3889.4±1580.6 kg,泌乳期为283.5±35.2 d,乳脂率为4.509%±0.58%。其中第1胎至第5胎305 d平均泌乳量分别为3395.4±740.81 kg,4123.4±1038.8 kg,5260.7±1728.9 kg, 5149.6±1988.4 kg和4896.3±1979.5 kg;第1胎至第5胎平均乳脂率分别为4.403±0.32%,4.561±0.63%,4.561±0.72%,4.470±0.35%和4.497±0.73%,第5胎及5胎以上个体305 d平均产奶量为4602.3±1478.4 kg,表明四川乳肉兼用牛具有较好的泌乳性能。

摘  要:
Milk yield of 2213 lactating cows of Sichuan dual purpose(milk and meat)cattle were recorded and milk fat percentage of 558 milk samples were analyzed in the study.The results showed that the average milk production,lactation length and milk fat percentage for all parities of Sichuan dual pur- pose cattle were 3889.4 kg,283.5 d and 4.51%,respectively,the average 305 d milk yield and fat per- centage for 1st,2nd,3rd,4th,and 5th calving were 3395.4±740.81 kg,4123.4±1038.8 kg,5260.7±1728.9kg,5149.6±1988.4 kg,and 4896.3%±1979.5 kg;4.403%±0.32%,4.561%±0.63%,4. 561%±0.72%,4.470%±0.35%,and 4.497%±0.73%,respectively,the 305 d milk yield of cows greater than 5th calving was 4602.3±1478.4kg,which demonstrated the super milking performance of Sichuan dual purpose cattle.
