Compound feed for clarias fuscus and preparation method and application of compound feed

Abstract

The invention belongs to the field of feeds, and discloses a compound feed for clarias fuscus and a preparation method and application of the compound feed. The compound feed for clarias fuscus comprises the following components of Japanese-grade imported fish meal, fermented soybean meal, dephenolized cottonseed protein, double-low rapeseed meal, beer yeast, porcine globulin powder, starch, cellulose, fish oil, soybean oil, an inorganic salt premix, a vitamin premix, choline chloride, chromium sesquioxide and amino acids, wherein the Japanese-grade imported fish meal accounts for 0.26-0.42 ofthe compound feed for clarias fuscus. According to the compound feed for clarias fuscus, provided by the invention, the fermented soybean meal, the dephenolized cottonseed protein, the double-low rapeseed meal, the beer yeast and the porcine globulin powder are used for replacing 25% of the Japanese-grade imported fish meal, the ingestion, the growth and the feed utilization condition of clariasfuscus are not influenced, the cost can be effectively reduced, and the product competitiveness can be improved.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a pond fish compound feed and a preparation method and application thereof. Background technique [0002] Pond catfish, fish, scientific name bearded catfish, also known as pond horn fish, belongs to Siluriformes and bearded catfish in classification. Beard catfish has smooth meat, delicious taste and rich nutrition. It is one of the famous and precious aquatic products loved by the masses. Pondfish also has the advantages of strong vitality, miscellaneous food habits, wide source of feed, short breeding cycle, and easy artificial reproduction. It is a freshwater aquaculture species with high economic value and suitable for promotion in rural areas in southern my country. The nutrient requirement of the protein in the feed is relatively high for pond fish, and the requirement for protein in the juvenile stage is about 36.5%. At present, more fishmeal is mainly used to meet the pr...

Problems solved by technology

However, there are still some problems in the replacement of a single protein source. For example, trypsin inhibitor and soybean lectin in soybean meal will hinder the synthesis of body protein and combine with the intestinal brush border mucosa of fish to cause intestinal tissue lesions. Gossypol in cotton meal Combining with lysine leads to decreased lysine activity, low methionine content of single-cell protein, extremely high lysine content in blood meal and extremely low isoleucine and methionine content
