【摘要】：本试验旨在研究饲粮中添加不同水平胡芦巴粉对肉仔鸡生长性能、肉品质、免疫器官指数及血清抗氧化和生化指标的影响。试验选用1日龄爱拔益加肉仔鸡320只,随机分为4个组,每组8个重复,每个重复10只鸡。各组分别饲喂含0(对照)、3%、6%、9%胡芦巴粉的营养水平相同的全价饲粮,试验期42d。结果表明:1)1~21日龄,6%和9%胡芦巴粉组平均体重和平均日增重显著低于对照组(P0.05),9%胡芦巴粉组平均日采食量显著低于对照组(P0.05),3%胡芦巴粉组料重比显著低于对照组(P0.05)。22~42日龄和1~42日龄,饲粮胡芦巴粉水平对肉仔鸡各项生长性能指标均无显著影响(P0.05)。2)9%胡芦巴粉组胸肌滴水损失率和压力损失率显著低于对照组(P0.05)。饲粮胡芦巴粉水平对胸肌pH45min、pH24h、剪切力和蒸煮损失率均无显著影响(P0.05)。3)6%胡芦巴粉组21日龄脾脏指数显著高于对照组(P0.05)。饲粮胡芦巴粉水平对21日龄胸腺指数、法氏囊指数及42日龄胸腺指数、脾脏指数和法氏囊指数均无显著影响(P0.05)。4)9%胡芦巴粉组的21日龄血清总超氧化物歧化酶活性高于对照组(P0.05),且显著高于3%和6%胡芦巴粉组(P0.05);6%胡芦巴粉组的42日龄血清总抗氧化能力显著高于其他各组(P0.05)。饲粮胡芦巴粉水平对21日龄血清总抗氧化能力和丙二醛含量以及42日龄血清总超氧化物歧化酶活性和丙二醛含量均无显著影响(P0.05)。5)9%胡芦巴粉组的21日龄血清谷草转氨酶活性显著高于对照组(P0.05);3%胡芦巴粉组的42日龄血清谷草转氨酶活性显著高于对照组(P0.05)。饲粮胡芦巴粉水平对21和42日龄血清总蛋白、白蛋白、球蛋白、尿素氮含量和白球比及谷丙转氨酶活性无显著影响(P0.05)。由此可见,胡芦巴粉可作为一种蛋白质饲料原料应用于肉仔鸡生产,其具有提高肌肉系水力,促进免疫器官发育,提高抗氧化能力和增强机体蛋白质代谢的作用。胡芦巴粉在肉仔鸡饲粮中的适宜添加水平为:1~21日龄不超过3%,22~42日龄不超过6%。
[Abstract]:The purpose of this experiment was to study the effects of different levels of fenugreek powder on growth performance, meat quality, immune organ index and serum antioxidant and biochemical indexes of broilers. They were randomly divided into 4 groups with 8 repeats in each group and 10 chickens in each replica. Each group was fed with a full price diet containing 0 (control group) with 6% fenugreek powder and 9% fenugreek powder with the same nutritional level. The results showed that the average body weight and average daily gain of the 6% and 9% fenugreek powder groups were significantly lower than that of the control group (P 0.05 + 9% fenugreek powder group), which were significantly lower than that of the control group (P 0.05%) and the average daily feed weight ratio of the control group (P 0.05%) was significantly lower than that of the control group (P 0.05%). Group A (P 0.05). 22 (42 days) and 1 (1) 42 days old. There was no significant effect of dietary fenugreek powder level on growth performance indexes of broilers. The pectoralis drop loss rate and pressure loss rate in fenugreek powder group were significantly lower than those in the control group. Dietary fenugreek powder level had no significant effect on the growth performance of broilers. The effects of dietary fenugreek powder level on pH 45 min pH 24 h, shear force and steam loss were significant. The spleen index of 21 days old group was significantly higher than that of control group (P 0.05. 05%, P 0. 05%, P 0. 05%, P 0. 05%, P 0. 05%, P 0. 05%, P 0. 05%, P 0. 05%, P 0. 05%, P 0. 05%, P 0. 05%). The bursa of Fabricius index and thymus index of 42 days old, The spleen index and bursa index had no significant effect on the activity of total superoxide dismutase (SOD) in the 21-day-old group of fenugreek powder group, and significantly higher than that in the group of 3% and 6% fenugreek powder group (P0.05% fenugreek powder group) and the 42-day-old serum of the group of 6% fenugreek powder with 3% and 6% fenugreek powder groups. The level of dietary fenugreek powder had no significant effect on the total antioxidant capacity and malondialdehyde content in 21-day-old serum, as well as on the total superoxide dismutase activity and malondialdehyde content in 42-day-old serum. The activity of serum glutamic oxaloacetic transaminase in the group of fenugreek powder was significantly higher than that in the control group (P 0.05%), and the activity of serum alanine aminotransferase in the group of forage fenugreek powder was significantly higher than that in the control group at the age of 42 days. The effect of dietary fenugreek powder level on the serum total protein of 21 and 42 days of age was significantly higher than that of the control group. The contents of albumin, globulin, urea nitrogen, white ball ratio and the activity of glutamate-pyruvate transaminase were not significantly affected. It can be seen that fenugreek powder can be used as a kind of protein feed raw material for broiler production, and it can improve the water power of muscle system. The optimum supplementation level of fenugreek powder in the diet of broilers was that the age of 1: 21 days was not more than 3 ~ 22 ~ (42) days old and the age of 6 ~ (th) was not more than 6 ~ (th) ~ (th).
