摘要
研究旨在探讨不同梯度饮水对商品肉鸭生长性能的影响。试验选用3 414只7周龄健康长白飞鸭商品肉鸭,将每日饮水量由每日6 t持续性饮水减少到每日3 t饮水,饮水模式由24 h持续性饮水过渡到每日3、4次间断性定时饮水,设3个重复,每个重复1 138只鸭。同时选用同批次3 359只健康商品肉鸭正常饮水作为对照组,设3个重复,每个重复分别为1 120、1 120和1 119只鸭。各组其他操作相同,试验期20 d。结果显示:不同梯度饮水对长白飞鸭商品肉鸭的增重无明显影响,试验组肉鸭10周龄体重为3.97 kg,对照组肉鸭10周龄体重为3.94 kg;试验组鸭群采食、饮水正常,没有出现应激、抢水、惊群现象,鸭群精神状态良好,无脱水、倦怠现象,鸭群采食量仅在节水初期有所下降,后期逐渐趋于平稳。研究表明,当采食量与饮水量比例为1∶4时,出现浪费水现象,比例为1∶2时,鸭群采食量明显下降,因此比例介于1∶2~1∶3之间较为合理。
The purpose of the study was to investigate the effects of different gradient drinking water on the growth performance of commercial meat ducks.In the experiment,3 414 seven-week-old healthy Changbai flying ducks were selected,their daily drinking water was reduced from 6 t of continuous drinking water per day to 3 t of drinking water per day,and the drinking mode was changed from 24 h of continuous drinking water to 3 or 4 times of intermittent drinking water per day,with three replicates and 1 138 ducks per replicate.At the same time,3 359 healthy commercial meat ducks in the same batch were selected as normal drinking water as the control group,with three replicates and 1 120,1 120 and 1119 ducks per replicate.Other operations were the same in each group.The experiment lasted for 20 days.The results showed that different gradient water intake had no significant effect on the weight gain of commercial broads of Changbai flying ducks.The body weight of broads at 10 weeks of age in the experimental group was 3.97 kg and that of broads in the control group was 3.94 kg.The ducks in the experimental group exhibited normal feeding and drinking behavior,without signs of stress,water grabbing,or flock disturbance.The ducks were in good mental condition,showing no signs of dehydration or fatigue.The feed intake of the duck only decreased slightly in the initial stages of water restriction,gradually stabilizing in the later period.The study indicates that when the ratio of feed intake to drinking water is 1∶4,there is a waste of water,and when the ratio is 1∶2,the feed intake of ducks decreased significantly,so the ratio between 1∶2 to 1∶3 is more reasonable.
