| Abstract: | 【Objective】In order to investigate factors influencing 305-days milk yield of Holstein cow.【Method】The effects of SAS8.1 GLM on 305-days milk yield were analyzed.【Result】Effect of different years on 305-days milk yield was highly significant(P<0.01);Effect of calving season on 305-days milk yield was highly significant(P<0.01),305-days milk yield was the highest in winter,the lowest in summer;Effect of different parities on 305-days milk yield was highly significant(P<0.01),the 305-days milk yield increased by the parity increased,decreased after the fifth parity;Effect of different first calving month age on 305-days milk yield was highly significant(P<0.01),the 305-days milk yield was the highest when first calving age during 24-26 months.【Conclusion】Year,calving season, parity and first calving month age were the main factors influencing 305-days milk yield. |
