高温季节不同日粮对蛋鸡血液生化指标和产蛋率的影响
0
()
摘要:
将1008只140日龄褐色罗曼蛋鸡随机分成7组,在夏季高温期间分别给予不同配方的日粮,观测血液生化指标和产蛋率的变化。结果表明,产蛋率与饲料代谢能和粗蛋白呈正相关,与血钠和氯化物呈负相关,与尿素氨和血糖呈正相关,而与血镁和血钙分别呈弱负相关和弱正相关,与其它指标无明显相关性。

Effect of Different Diets on Blood Biochemical Parameters and Laying Rate of Layers Under High Temperature
()
Abstract:
One thousand and eight brown layers aged 1 4 0 days were randomly divided into 7 groupsunder high temperature , which were fed with different diets respectively .The changes of bloodbiochemical parameters and laying rates were examined. The result showed that high protein dietincreased laying rate and blood biochemical parameters changed significantly. The correlations be- tween laying rate and serum chloride and sodium were significant(p<0.05), Those of serum calcium and magnesium with laying rate were mildly positive and mildly negative ,respectively,and blood urea nitrogen and glucose were mildly correlated with laying rate(P<0.05).
Key words:  Layer,Laying rate,High temperature,Diets,Blood biochemical parameter,
