复方布他磷对分娩母猪及哺乳仔猪生产性能的影响

Effects of Butafosfan on Performance in Sows and Piglets

选择相同胎次、长×大二元杂交的健康妊娠母猪16头（妊娠80±2 d）,随机分为两组,每组8头。对照组饲喂基础饲粮,不添加任何添加剂;试验组在母猪分娩前1个月~断奶后7 d,饲料中添加复方布他磷（加饲福）1 kg·t-1,混合均匀后直接喂饲。试验在相同的饲养管理条件下进行。结果表明,试验组母猪分娩产程比对照组缩短52 min,差异显著（P〈0.05）,仔猪初生重提高了20%,差异不显著（P〉0.05）,仔猪断奶重提高了22%,差异极显著（P〈0.01）,断奶后母猪的发情率提高了16.67%,差异显著（P〈0.05）,说明布他磷对改善产后母猪的发情率效果明显。

Sixteen healthy sows（pregnent 80±2 d） were randomly divided into two groups in accordance with the same paritys, eight in each group. Control group fed sows basic diets without any antibiotics or butafosfan; the experimental group fed with the same diets which added 0.1% butafosfan. The experiment was conducted to investigate the effect of butafosfan on sows and piglets performance. The results indicated that the birth time of the experimental group was shorter than the control group 52 minutes（P0.05）. The birth weight and the weaned weight of the experimental group was higher than the control group 20% and 22%（P0.01）. The sows estrus of the experimental group was higher than the control group 16.67% which indicated butafosfan could improve the estrus of the sows（P0.05）.
