肉羊饲喂全混合颗粒饲料对其采食行为的影响

Effects of Feeding Total Mixed Pellet Feed to Mutton Sheep on Their Feeding Behavior

本试验通过开展粗饲料资源玉米秸秆和苜蓿干草不同比、不同精粗比全混合颗粒饲料肉羊饲喂试验,观察记录肉羊采食行为。最终得出结论:饲喂全混合颗粒饲料,采食时间缩短30~40 min左右,采食速度提高,增加了采食量;粗饲料比例越高,肉羊饮水次数和饮水时间越长;精饲料比例越高,肉羊排便次数增加;精粗比对肉羊的运动和休息时间没有显著影响。通过观测各指标得出结论:A3B2组饲喂效果最好。

In this experiment,we conducted a feeding experiment on sheep with complete mixed pellet feeds of corn straw and alfalfa hay with different ratios of roughage resources,and different concentrate-to-rough ratios,and observed and recorded the feeding behavior of the sheep.Finally,it was concluded that by feeding fully mixed pellet feed,the feed intake time was shortened by about 30 to 40 minutes,the feed intake speed was increased,and the feed intake was increased.The higher the proportion of roughage,the longer the mutton sheep drink water.The higher the proportion of concentrated feed,the more frequent bowel movements of mutton sheep.The semen-to-grain ratio had no significant effect on the exercise and rest time of mutton sheep.This study concluded that the A3B2 group had the best feeding effect by observing various indicators.
