地暖式育雏温湿度监测与育雏效果分析
首发时间:2018-10-08
摘要:在集约化养鸡生产中出于全进全出等生物安全考虑,需要一个批次育雏数量越来越多,育雏规模也越来越大,因此迫切需要一种适合大规模育雏舍的育雏供暖模式。本实验选取一个单栋7.2万只育雏舍开展实验,监测并记录了1-42日龄育雏舍前、中、后部的温湿度,同时测量雏鸡的体重、胫长、采食量、死淘率等指标。结果显示,地暖式育雏舍内温湿度相对稳定,鸡群耗料量低于标准而体重高于标准,成活率和均匀度分别为98.8%、93.8 %。育雏效果良好。我国北方地区采用地暖育雏技术可有效促进体重和骨骼的发育,提高育雏成活率和均匀度,尤其适合于大型规模化育雏。

Temperature and Humidity Monitoring and Brooding Effect Analysis of Geothermal Brooding
Abstract:In the intensive chicken production, for the biosafety consideration of all in and all out, more and more chicks in one batch are required, and the scale is also growing. Therefore, there is an urgent need for a heating mode to large scale brooding houses.The experiment selected one house of 72000 chicks. Temperature and humidity were monitored and recorded at the front, middle and rear of 1-42 days, and measured the body weight, shank length, feed intake and death rate of the chicks. The results showed that the temperature and humidity were relatively stable, the consumption was lower than the standard and the weight was higher than the standard. The survival rate and uniformity were 98.8% and 93.8%, respectively. The effect of brooding was good. In northern China, the use of geothermal brooding technology could effectively promote the development of body weight and bone, and improve the survival rate and uniformity, especially for large-scale brooding.
