South China Agricultural University on bile acids on the growth performance, immune function, etc. of South America on shrimp, and the aquatic forum – China Animal Husbandry Website – A useful animal husbandry website

Bile acid is the main component of the bile secreted by animal liver, stored in a gallbladder, has the effect of promoting fat emulsification, digestion, and absorption, and can also improve animal liver and intestinal health through intestinal-liver circulation. Ball bile acid feed additives made from the active ingredient extracted from animal bile cream by new techniques, using metabolism and absorption of fat and cholesterol in the liver in South American white shrimp, promote the development of the liver, improve Immunity of the body, improve the health of the liver, effectively prevent enteritis, white invasive, liver atrophy, liver dying, reduce the incidence, and improve the survival rate.

This experiment takes a study of South America to the prawns (also known as Nahabizin shrimp) to the study, observe the effect of bile acid on its growth performance, digestive enzyme activity, serum biochemical and immunoactive index. First, Test Location: Aquaculture Laboratory of South China Agricultural University
Second, Test Time: July 2, 2011 – October 2nd.
Three, for test materials:
South American white peer: Test South American white peer shrimp is provided by Yuehai Feed Group Co., Ltd. shrimp seedlings, weight 0.30 ± 0.02 g.
Bile Acid: Produced by Shandong Longchang Animal Health Products Co., Ltd., mainly 20% of bile acids.
Four, Test Design:
400 Tailfan Bin Purchase randomly is divided into control group and test group, each group of 200, 5 repetitions per group, each repeating 40 tail. Favoraning the basic diet of the control group, the test group added 700 grams of bile acids per ton in the base diet.
At the end of the test, the growth performance, fat enzyme activity, alkaline phosphatase (ALP), superoxidase (SOD) and lysozyme (LSZ) activity of the test were determined.
V. Test results:

It is to be seen that the experimental group is increased by 5.54% compared to the control group; the survival rate is increased by 11.94%; the bait coefficient decreases by 4.73%, and the difference is significant (P

or more results showed that 700 grams of bile added in one ton of feed Acid (20% content) can significantly improve the survival rate and weight gain rate of South America to shrimp, reduce the bait coefficient, increase economic benefits. Bile acid increases the activity of South America to shrimp pancreatic lipase, which proves that bile acid has improved shrimp Digestive utilization rate of feed. <0.05);胰脂肪酶活性呈上升趋势,试验组提高55.26,差异显著(p<0.05)。

It can be seen from Table 2 that alkaline phosphatase and superoxide dismutase have an upward trend as compared with the control group, but the difference is not significant (P> 0.05); Lysozyme increases by 20.03%, the difference is significant (P

, and the results of Nanoli brown shrimp feed can give serum lysozyme, superoxide dismutase and alkaline phosphatase have different degrees of increase, prove Bile acid enhances the liver function and non-specific immune function of shrimp.

Six, summarizing

Adding bile acids in South White to increase the growth performance, fat enzyme activity, enhance its liver function and non-specific immunity Function, thereby improving the survival rate of prawns in South America. WeChat picture _20180920095818.jpg <0.05)。
