【摘要】：本试验旨在研究豌豆蛋白粉对1~4周龄高邮鸭生长性能、养分表观消化率、消化器官发育及血清生化指标的影响。试验选用160只1日龄高邮鸭,随机分为4个组,每组4个重复,每个重复10只鸭。对照组(C0组)饲喂玉米-豆粕型基础饲粮,试验组(C1、C2、C3组)分别饲喂以3%、6%、9%的豌豆蛋白粉替代基础饲粮中豆粕的试验饲粮。试验期28 d。结果表明:1)C1、C2、C3组的平均日增重和平均日采食量均显著低于对照组(P0.05);C1组的料重比显著高于对照组(P0.05),C2、C3组的料重比与对照组差异不显著(P0.05)。2)C1、C2、C3组的粗蛋白质(CP)和总磷(TP)表观消化率与对照组差异不显著(P0.05),C2组的粗纤维(CF)、粗脂肪(EE)和钙(Ca)表观消化率与对照组差异不显著(P0.05),C1、C3组的CF、EE和Ca表观消化率均显著低于对照组(P0.05)。3)豌豆蛋白粉对腺胃、胰腺和十二指肠的相对重量没有显著影响(P0.05)。C1组的肌胃相对重量显著高于对照组(P0.05),C2组的空肠和回肠相对重量均显著高于对照组(P0.05),C2组的十二指肠密度、空肠密度和回肠相对长度均显著高于对照组(P0.05)。4)豌豆蛋白粉对血清白蛋白(ALB)、葡萄糖(GLU)、低密度脂蛋白胆固醇(LDLC)含量没有显著影响(P0.05),C3组的血清总蛋白(TP)含量显著高于对照组(P0.05),C2、C3组的血清尿素氮(UN)含量均显著高于对照组(P0.05),C1、C2、C3组的血清甘油三酯(TG)含量均显著高于对照组(P0.05),C1、C3组的血清总胆固醇(TC)、高密度脂蛋白胆固醇(HDLC)含量显著低于对照组(P0.05)。综上,饲粮中使用豌豆蛋白粉替代豆粕会降低1~4周龄高邮鸭的平均日增重和平均日采食量,但6%豌豆蛋白粉替代豆粕对养分表观消化率没有显著影响,料重比低于对照组,而且有助于小肠器官发育指数提高,影响体内蛋白质和脂肪代谢的变化。建议6%豌豆蛋白粉作为高邮鸭饲粮的推荐使用量。
[Abstract]:The purpose of this study was to study the effects of pea protein powder on growth performance, apparent nutrient digestibility, digestive organ development and serum biochemical indexes of 1-4 week old Gaoyou duck. 160 1-day-old Gaoyou ducks were randomly divided into 4 groups with 4 replicates in each group and 10 ducks per replica. The control group (C0 group) was fed with corn-soybean meal diet, and the experimental group (C1C2C3 group) was fed with 3% pea protein powder instead of soybean meal in the basal diet. The trial period was 28 days. The results showed that the average daily gain (ADG) and average daily intake of C _ (1) C _ (2) C _ (3) were significantly lower than those of the control group (P0.05). The feed weight ratio of C _ (1) C _ (2) C _ (3) C _ (1) C _ (1) C _ (3) group was significantly higher than that of the control group (P < 0.05). The apparent digestibility of crude fiber (CF), (EE) and calcium (Ca) in C _ 2 group was not significantly different from that in control group (P0.05). The apparent digestibility of CFEE and Ca in C _ 1 C _ 3 group was significantly lower than that in control group (P 0.05), and the apparent digestibility of pea protein powder in glandular stomach of C _ 2 group was significantly lower than that in C _ 1 C _ 3 group. There was no significant effect on the relative weight of pancreas and duodenum (P0.05). The relative weight of muscle stomach in group C1 was significantly higher than that in group C _ 2 (P0.05), and the relative weight of jejunum and ileum in group C _ 2 was significantly higher than that in group C _ 2 (P0.05). Jejunum density and ileum relative length were significantly higher than those in control group (P0.05). Pea protein powder had no significant effect on serum albumin (ALB), glucose, (GLU), low density lipoprotein cholesterol (LDLC) content. (P0.05) Serum total protein (TP) content in C _ 3 group was significantly higher than that in C _ 3 group. The content of serum urea nitrogen (UN) in group C _ (2) C _ (3) was significantly higher than that in group C _ (1) C _ (2) C _ (3) (P0.05). The content of serum triglyceride (TG) in C _ (1) C _ (2) C _ (3) group was significantly higher than that in group C _ (1) C _ (3) compared with the control group (P 0.05). To sum up, the average daily gain and average daily intake of 1 ~ 4 weeks old Gaoyou duck could be reduced by replacing soybean meal with pea protein powder, but the apparent nutrient digestibility was not significantly affected by 6% pea protein meal replacement, and the feed weight ratio was lower than that of the control group. Moreover, it can improve the development index of small intestine and affect the changes of protein and fat metabolism. It is suggested that 6% pea protein powder should be used as a recommended diet for Gaoyou duck.
