摘  要：
为研究夏季高温条件下产房母猪饮水器单位时间内出水量对哺乳母猪生产性能、便秘情况等的影响,选取84头体况和预产期相近的长大杂种母猪,根据胎龄和体况等参数随机分为试验A组(出水量为1.2 L/min)、试验B组(出水量为1.7 L/min)、试验C组(出水量为2.2 L/min)和试验D组(出水量为2.7 L/min),每组设3个重复,每个重复7头母猪。饲粮、饲养管理和免疫程序等条件均一致。试验周期为从母猪妊娠107 d转入产房直至断奶(仔猪23日龄断奶)后发情,约36 d。结果显示:试验D组(最高出水量组)哺乳母猪断奶-发情间隔以及仔猪断奶个体重(23日龄)显著或极显著优于其它试验组。此外,试验D组哺乳母猪的便秘率低于其它试验组,断奶后7 d内发情率高于其它试验组。提示饮水器高出水量有利于提高哺乳母猪的生产性能。

摘  要：
This study is aimed to investigate the effect of water flow rates of drinkers on the farrowing performance,constipation and production performance of sows in farrowing pens under high temperatures in summer.In this study,84 Landrace and Yorkshire hybrid sows with similar body condition and predicted farrowing time were selected and randomly divided into two groups according to the parameters of gestational age and body condition: Group A(water flow rate of 1.2 L/min),Group B(1.7 L/min),Group C(2.2 L/min) and Group D(2.7 L/min). The effect of different water flow rates of drinkers in farrowing pens on the farrowing performance of lactating sows was investigated under the conditions of identical diet,feeding management and immunization procedure. The test period was about 36 days,from when the sows were transferred to farrowingpens until estrus after weaning(piglets 23 days old). The results show that the weaning-estrus interval of lactating sows,as well as the weaning weight of piglets(23 days old) in group D(with the highest water flow rate) were significantly or extremely significantly better than those in other experimental groups. In addition,the rate of constipation in group D was lower than that in other groups,and the rate of estrus was higher than that in other groups within 7 days after weaning,indicating that the high water flow rate of drinkers is conducive to the production performance of lactating sows.
