肉鸽不同生理阶段采食量与采食速度观察

Observation on the Feed Intake and the Feeding Speed of Meat Pigeon at Different Physical Stages

目的:为了解生产种鸽不同生理阶段采食速度和不同采食时间段采食量的变化情况。方法:以商品肉鸽一个生产周期的6个不同生理阶段组成6个试验组,按照每日2餐,每餐每组试验鸽定量投喂、定时称取剩料的方法,在上海某规模鸽场开展了一次较为系统的测定试验。结果:生产种鸽的采食速度较快,整个生产周期各阶段的餐后0.5 h采食量日均值占日总采食量日均值的84%左右,而且生产种鸽一个生产周期内不同生理阶段的采食量差异较大,高峰值可达空巢期的3倍左右,并以哺育早期的采食量增长最为明显。结论:建议在采用2餐制饲养模式时,生产种鸽的单餐投喂量:空巢期和孵化期为35~40 g/对;哺育早期应逐步增加投喂量至45~60 g/对;雏鸽7日龄开始应快速增加投喂力度,至10日龄时应达到120 g/对高峰值,并维持1周左右;育肥期可逐步减少投喂量,至出栏前维持在90 g/对左右。

Objective:To understand the changes in the feeding speed at different physical stages and the feed intake in different feeding periods of producing feeding pigeons.Method:A systematic measurement experiment was conducted at a large-scale pigeon farm in Shanghai.The commercial meat pigeons were seperated into six groups based on six different physical stages.The pigeons were fed two meals per day.The feedings were given quantitatively and the lefovers weighed regualrly.Result:The feeding speed was faster in the producing breeding pigeons.In each stages of the producing cycle,the feed intake at 0.5 h after meal accounted for 84%of the total daily intake.The feed intake had a significant difference between different physical stages.There was a significant increase in the early stage of feeding.The peak value was three times higher than that of the empty nest period.Conclusion:A 2-meal feeding model was recommended.The producing breeding pigeons at different physical stages should be provided with different feeding amount:35~40 g/pair for the empty nest period and the incubation period,45~60 g/pair for the early feeding stage.The feed amount should start to increase for the pigeons after 7 days old,reaching a peak of 120 g/pair for the pigeons of 10 days old,and maintain for about 1 week.The feeding amount could reduce from the fattening period,and reduced to around 90 g/pair until release.
