| 摘 要： | 蛋壳质量是衡量蛋鸡生产性能的重要指标之一,目前关于海兰褐商品蛋鸡不同产蛋期血液钙磷与蛋品质的相关性研究还未见报道。本文通过研究不同产蛋期海兰褐蛋鸡血清钙磷水平变化与蛋品质变化的相关性,以期为改善蛋品质,保障笼养海兰褐蛋鸡健康和生产提供理论依据。试验采用随机单因素方差设计,选取产蛋前期(23周龄)、产蛋高峰期(43周龄)和产蛋后期(71周龄)的海兰褐商品蛋鸡各8只,进行称重、采血;同时收集各时期同天所产的鸡蛋,各周龄18枚。结果显示,不同产量期血钙含量依次升高,且差异显著(P0.05);血磷含量各组间无显著差异(P0.05);蛋壳厚度和强度在产蛋后期明显降低,且与前期和高峰期差异显著(P0.05);蛋品质指标仍在正常范围内。71周龄时,蛋品质降低,机体已经出现钙磷的代谢紊乱,需要适当调整饲料钙磷添加量,以提高蛋的品质。

| Abstract: | Eggshell quality is an important production performance indicator of the laying hens.There are few reports about the correlation between the blood calcium and phosphorus concentrations in different laying period and the egg quality of Hyline brown laying hens.This paper focused on the correlation between the serum calcium and phosphorus concentrations and the changes of the egg quality in order to improve the egg quality and provide theoretical basis for the safeguard of the health and production of Hyline layers.Random single factor variance test was designed, and Hyline brown laying hens in the early laying period (23 weeks), peak period (43 weeks) and late laying period (71 weeks) were selected, 8 hens in each period.The body weight were recored and blood were collected.Eggs on the same day were collected, 18 eggs for each period.The results showed that blood calcium improved with the increase of age, and there were significant differences (P<0.05).There were no significant differences in the blood phosphorus (P>0.05).The thickness and strength of eggshells decreased in the late period compared with the early and peak periods (P<0.05).Egg quality indicators were in the normal range.The above results indicated that egg quality decreased in the 71 week, and there were discorders of calcium and phosphorus metabolism, so the contents of calcium and phosphorus in the feed should be increased to improve egg quality. |
