摘要
[Objective] This study aimed to investigate the effects of different padding on ammonia concentration in broiler house and growth performance and blood indi- cators of broilers. [Method] A total of 480 one-day-old 817 broilers were selected. They were randomly divided into four groups with different paddings, and each group was in triplicate. The weights of broilers and feed were weighed weekly. The growth performance of broilers was determined. On day 30, the ammonia concentra- tions in broiler houses were determined. On day 35, 6 broilers were randomly se- lected from each group, and their vein blood was sampled. In the sampled vein blood, the concentrations of ammonia, glucose, globulin, serum total protein and urea nitrogen were determined. [Result] There were significant differences in ammo- nia concentration among broiler houses laid with different paddings （P〈0.05）. The ammonia concentration in group 1 was significantly lower than those in group 3 and group 4 （P〈0.05）. No significant difference was found in ammonia concentrations in broiler houses between group 2 and group 3 （P〉0.05）. The ammonia concentration in group 4 was significantly higher than those in group1, group 2 and group 3 （,0〈 0.05）. There were also significant differences in blood indicators among different groups （P〈0.05）. The blood ammonia, blood glucose and serum urea nitrogen con- centrations in group 1 were significantly lower than those in other groups （P〈0.05）, the serum total protein concentration was significantly higher than those in group 3 and group 4 （P〈0.05）, and the serum globulin concentration was significantly higher than those in group 2, group 3 and group 4 （P〈0.05）. Significant differences were observed in feed intake, body weight gain and slaughter weight between different groups （P〈0.05）, but there were no significant differences in feed to grain ratio （P〉 0.05）. [Conclusion] Under the experimental conditions, the padding of Chinese medicine residue showed bet
[目的]探讨不同垫料对肉鸡舍内氨气浓度、肉鸡血液生化指标和生产性能的影响。[方法]选1日龄817肉鸡480只,平均分成4组,每组3个重复,各组铺洒不同的垫料。第30天,检测舍内氨气浓度;第35天,每组选6只鸡翅静脉采血,测血氨、血糖、血清总蛋白、球蛋白、血糖及尿素氮浓度;每周称鸡重、料重,测定生产性能。[结果]舍内氨气浓度有显著差异(P<0.05),1组显著低于3组和4组(P<0.05),2、3组差异不显著(P>0.05),4组显著高于1、2、3组(P<0.05);各组血液生化指标差异显著(P<0.05),1组血氨、血糖和血清尿素氮的浓度显著低于其它各组(P<0.05),血清总蛋白浓度显著高于3组和4组(P<0.05),血清球蛋白浓度显著高于2、3、4组(P<0.05);采食量、体增重和出栏体重差异显著(P<0.05),各组料重比差异不显著(P>0.05)。[结论]该试验条件下,中药渣作为垫料对降低鸡舍氨气浓度具有很好的效果,有利于肉鸡生产潜能的发挥。
