摘要
为研究不同光照强度对雏鸡生长性能及体重均匀度的影响,本试验选取刚完成转群的28日龄海兰褐雏鸡480只放入1栋半开放式鸡舍,光照强度由照明设施和饲养位置决定。利用光照度计对光照强度进行测定,并根据鸡舍内光照强度不同将雏鸡分为强光组(84.10±66.67 lx)和弱光组(3.42±2.44 lx),每组设4个重复,每个重复60只鸡,试验期为28 d,记录鸡群在4~8周龄的生长性能及体重均匀度情况。结果表明:雏鸡在第5周更适合弱光光照,第6周之后,强光组与弱光组在生产性能以及体重均匀度上差异不显著,但是强光组比弱光组更加适合雏鸡生长,提高雏鸡体重均匀度。
In order to study the effects of different light intensities on growth performance and body weight uniformity of chicks,a semi-open house was selected to feed 480 Hyland brown chickens of 28 days of age,which had completed the conversion. The light intensity was determined by the lighting facilities and the feeding position. The chicks were divided into an intense light group（ 84. 10 ± 66. 67 lx） and a low light group（ 3. 42 ± 2. 44 lx） by the light intensity measured by illuminometer in the house. Each group had 4 replicates and each replicate had 60 chickens. The test period was 28 days and the growth performance and weight uniformity of the tested chickens at 4 to 8 weeks of age were recorded. The results showed that the chicks were more suitable for low-light illumination on the 5 th week,and there was no significant difference in production performance and body weight uniformity between the high-light group and the low-light group after 6 weeks. However,the intense light group was more suitable for the growth of chicks than the low light group,and increased the weight uniformity of the chicks.
