摘要:

本试验旨在利用呼吸舱测定白羽肉鸡氨气排放率(ER),并研究其排放趋势。选取1日龄、健康的爱拔益加肉鸡300只随机分配在3个呼吸舱中(公母各半),采用网上平养一次性清粪的饲养方式饲喂至42日龄。试验期间实时监测通风量和进气口、排气口处的氨气浓度,计算氨气排放量。试验结果为:白羽肉鸡生长42 d内平均每只鸡的氨气排放量为(2 777.78±55.58)mg,平均氨气排放率为(66.14±1.32)(mg·只-1)·d-1,上市体重为(2 530.95±57.74)g。肉鸡氨气排放在1~18 d维持平稳,之后随日龄增加而增大。

Abstract:

This experiment was conducted to measure the NH3 emission rate and investigate emission characteristics using respiratory chamber. Three hundred and 1-day-old healthy Arbor Acres broilers with similar body weight were randomly allotted into three respiratory chambers.The broilers were reared on the net and manure was not cleaned until 42 d.A continual monitoring system for monitoring ventilation rate and the NH3 concentration was used in this research to determine ammonia emission.The results showed as follows:total ammonia emissions during 1 to 42 d were estimated to (2 777.78±55.58)mg per bird,and mean ER was (66.14±1.32)(mg·bird-1)·d-1 with body weight (2 530.95±57.74)g.The daily ER during 1 to 18 d remains stable,and then showed a increasing trend with age of broiler.
