Embodiment 1

[0012] First, prepare the clam shell powder: clean the fresh clam, add 2 liters of water to each kilogram of fresh clam and boil for 5 minutes, pick out the shell, clean it, dry it at room temperature, and calcine it at 550°C for 2 hours. Pulverize and pass through a 60-mesh sieve to obtain river clam shell powder. Then, in the basal feed of cultured fish, add the clam shell powder, the addition of the clam shell powder is 1% of the total weight of the basal feed for the cultured fish; then mix the basalt shell powder and the basal feed of the cultured fish evenly, Made into granules, sealed and stored after drying.

Embodiment 2

[0014] First, prepare the clam shell powder: clean the fresh clam, add 2 liters of water to each kilogram of fresh clam and boil for 5 minutes, pick out the shell, clean it, dry it at room temperature, and calcine it at 550°C for 2 hours. Pulverize and pass through a 60-mesh sieve to obtain river clam shell powder. Then, in the basal feed of cultured fish, add clam shell powder, the addition of the clam shell powder is 2% of the total weight of the basal feed of cultured fish; Made into granules, sealed and stored after drying.

Embodiment 3

[0016] First, prepare the clam shell powder: clean the fresh clam, add 2 liters of water to each kilogram of fresh clam and boil for 5 minutes, pick out the shell, clean it, dry it at room temperature, and calcine it at 550°C for 2 hours. Pulverize and pass through a 60-mesh sieve to obtain river clam shell powder. Then, in the basal feed of cultured fish, add clam shell powder, the add-on of clam shell powder is 3% of the total weight of the basic feed of cultured fish; Made into granules, sealed and stored after drying.

[0017] In order to verify the application effect of the fish clam shell powder lipid-lowering compound feed prepared by the present invention, the following specific data will illustrate that the fish clam shell powder lipid-lowering compound feed of the present invention can reduce liver disease in the hibiscus carp and crucian carp feed. The role of body index, visceral body index, blood lipids and liver lipase:

[0018] Prepare the base feed with the f...

Abstract

The invention discloses a preparation method of a lipid-lowering corbicula fluminea shell powder compound feed. The preparation method specifically comprises the steps of firstly, adding corbicula fluminea shell powder into a basal feed for culturing fish, wherein the adding amount of the corbicula fluminea shell powder accounts for 0.75%-3.25% of the total weight of the basal feed; then uniformly mixing the basal feed, namely corbicula fluminea shell powder, to prepare particles, and drying to obtain the compound feed. The feed prepared by the invention can be used for not only lowering the index of the fish liver and serum triglyceride, but also obviously improving the activity of hepatic lipase.

Description

technical field [0001] The invention relates to a method for preparing a feed for aquaculture fish, in particular to a method for preparing a fat-reducing compound feed of river clam shell powder for aquaculture fish. Background technique [0002] At present, with the continuous development of intensive aquaculture in my country, fish fatty liver, which is caused by excessive accumulation of liver lipids as the main pathogenic factor, has attracted widespread attention. The disease has a high morbidity and high mortality rate in farmed fish, and has become an important problem hindering the further development of aquaculture. How to prevent and treat fatty liver in fish has become one of the problems that aquaculture needs to solve urgently. At present, it is an important means to prevent fish fatty liver by adding lipid-lowering factors in the feed in an appropriate amount to improve the fat metabolism of fish. [0003] As a traditional Chinese medicinal material, river cl...
