Abstract
[Objectives]The differences in the growth performance of Hy-Line brown laying hens during the period of rearing in different chicken houses were studied to provide a theoretical and practical basis for the feeding and management of Hy-Line brown laying hens during the period of rearing.[Methods]3 chicken houses named as H1,H2,H3 were selected from a pullet farm in Jingchuan County,Gansu Province,in Octo-ber 2024.30 Hy-Line brown laying hens were randomly sampled from each chicken house to measure the indi-vidual body weight of laying hens aged 7 to 17 weeks.Descriptive statistics and analysis were conducted on the data of weekly body weight in each house throughout the period of experiments.The value of absolute growth and relative growth from 8 to 17 weeks of age was calculated with the basic data measured,and one-way analy-sis of variance(ANOVA)was used to compare the body weights of Hy-Line brown laying hens from the 3 chicken houses by the week of age.[Results]The average body weight,standard deviation and coefficient of variation of Hy-Line brown laying hens in 3 chicken houses all had a trend of increasing during the period of rearing at each week of age.There were significant differences in the body weight at 12 weeks of age.The aver-age body weight in H3 and H2 was significantly higher than that in H1 by 6.17%and 3.75%(P＜0.05).There were differences in the weekly body weight among 3 chicken houses.Significant differences in the body weight existed at the stage of rearing at 8 and 9 weeks of age(P＜0.05),whereas no significant difference was found at the stage of rearing at 11 weeks of age and 13 to 17 weeks of age(P＞0.05).The absolute growth of laying hens at each week of age differed greatly among 3 chicken houses without an obviously regular pattern of variation.The relative growth of laying hens had an overall trend of declining with drastic fluctuations.The curves of ab-solute growth and relative growth of laying hens in the 3 chicken houses diverged the most at 12 weeks of age,with the maximum values exceeding the minimum values by 210.5%and 203.2%,respectively.[Conclusions]There were differences in the growth and development of Hy-Line brown laying hens among different chicken houses during the period of rearing.The feeding and management of each chicken house is a key factor affect-ing the uniformity and flock consistency of body weight in laying hens during the period of rearing.Standard-ized practices of scientific feeding should be strictly followed throughout the process of production.关键词
