摘要:

【目的】研究在黄羽肉鸡日粮中添加发酵棉籽粕膳食纤维(fermented cotton meal fiber,FCMF)对其生长性能、屠宰性能和肠道形态的影响。【方法】取120只1日龄健康黄羽肉鸡,随机分成两组,即对照组(CON组)和试验组(FCMF组),分别饲喂添加1.2%未发酵棉籽粕膳食纤维和1.2%发酵棉籽粕膳食纤维的日粮,每组6个重复,每个重复10只鸡,分栏笼养。【结果】各阶段两组的肉鸡生长性能无显著差异(P>0.05)。在35日龄时,FCMF组半净膛率极显著高于CON组(P<0.01),全净膛率提高了3.63%(P<0.05)。在35日龄时,FCMF组的十二指肠绒隐比(VH/CD)显著提高,回肠绒毛高度(VH)与CON组相比差异显著(P<0.05),十二指肠绒毛高度(VH)与CON组相比差异极显著(P<0.01)。在56日龄时,FCMF组的回肠VH化差异极显著(P<0.01)。【结论】日粮中添加FCMF可以提高黄羽肉鸡的全净膛率和半净膛率、十二指肠和回肠绒毛高度以及十二指肠绒隐比及回肠绒毛高度,具有改善黄羽肉鸡屠宰性能和促进肠道发育的作用。

Abstract:

【Objective】This experiment aims to study the effects of adding fermented cottonseed meal fiber (FCMF) to broiler diets on growth performance, slaughter performance and intestinal morphology. 【Methods】120 1-day-old healthy yellow feather broilers were taken and randomly divided them into two groups, namely the control group (CON group) and the test group (FCMF group). They were fed with 1.2% unfermented cottonseed meal dietary fiber and 1.2% fermentation. The diet of dietary fiber from cottonseed meal, 6 replicates in each group, and 10 chickens in each replicate, were kept in separate cages. 【Results】There was no significant difference in the growth performance of the two groups of broilers at each stage (P>0.05). At the age of 35 days, the half evisceration rate of the FCMF group was significantly higher than that of the CON group (P<0.01), and the full evisceration rate increased by 3.63% (P<0.05). At 35 days of age, the duodenal villus hidden ratio (VH/CD) and ileal villi height (VH) of the FCMF group were significantly different from those of the CON group (P<0.05), and the duodenal villus height (VH) was extremely different (P<0.01). At 56 days of age, the ileal VH of the FCMF group was significantly different (P<0.01). 【Conclusion】There are not significant effects on on the growth performance of yellow-finned broiler chickens, but FCMF could improve the full-cleaning and half-cleaning rates of yellow-finned broilers. Meanwhile, they could improve duodenal villus height, duodenal villus crypt ratio and ileal villus height, and promote intestinal morphology development in yellow-feathered broiler chickens.
