Compound feed for groupers and preparation method thereof

Abstract

The invention provides a compound feed for groupers and a preparation method thereof. The compound feed comprises the following raw materials: 10-20 parts of soybean meal; 5-10 parts of flour; 5-10 parts of vital gluten; 13-25 parts of peanut meal; 2-8 parts of shrimp bran; 30-70 parts of yellow mealworm powder; 3-8 parts of chicken powder; 0.5-2 part of monocalcium phosphate; 4-10 parts of soyabean lecithin; 2-5 parts of soybean oil; and 2-5 parts of fish oil. The preparation method comprises the following steps: weighing the raw materials according to the proportion, and carrying out crushing and sieving; mixing the raw materials uniformly according to the proportion, and carrying out blending and granulating. The prepared feed is comprehensive in nutrition, the breeding cost is reducedby adding the tenebrio molitor powder, the bait coefficient is reduced, the breeding benefit is improved, the grain forming degree and the stability in water of the feed are obviously improved by adding the vital gluten with excellent vegetable protein and high gluten content, the utilization rate of fish to the feed is increased, the disease resistance of grouper bodies is improved, the intestinal health is kept, and the breeding survival rate is increased.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a compound feed for grouper and a preparation method thereof. Background technique [0002] Grouper is a cold-water fish with great development value. It has delicious meat and rich nutrition. It is a very popular seafood in the market. Although there are many studies on the nutritional requirements of grouper, the development and utilization of compound feed is still in its infancy. The cultured grouper in my country is mainly fed with chilled small miscellaneous fish, and some feed factories are trying to produce and promote grouper feed, but basically they cannot use compound feed throughout the entire breeding process, and more importantly, compound feed There are problems such as the comprehensiveness of nutrition, food attraction, growth promotion and disease resistance and disease prevention ability. Contents of the invention [0003] The invention aims to solve the...
