Special feed for tilapia

Abstract

A special feed for tilapia is prepared from the following raw materials in parts by weight: 10-20 parts of fish meal, 5-10 parts of pork powder, 20-30 parts of tapioca flour, 4-6 parts of chicken liver powder, 1-3 parts of edible salt, 22-28 parts of soybean meal, 2-6 parts of malt root, 3-5 parts of brewer's grain, 5-10 parts of peanut meal, 6-10 parts of cottonseed meal, 6-10 parts of rapeseed meal, 12-18 parts of wheat bran, 4-10 parts of soybean oil and 3-5 parts of a feed premix. According to the invention, the pork powder is used for replacing a part of the fish meal, the water-soluble protein, the insoluble protein and the fat content of the fish meal are all lower than that of the pork powder, the production cost is reduced, and the fat content of the feed is improved; the tapiocaflour is used for replacing an energy feed with a relatively high price such as common corn or wheat, the average dry matter digestibility of the tapioca flour is 75%, the organic matter digestion rate is higher than 85%, the starch digestion rate is higher than 87%, the special feed is close to cereals, is easy to be digested by the tilapia, almost has no mould pollution, and has great benefits for maintaining the health of the tilapia, and in addition, the use of a mildew preventive in the feed can be reduced.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to a special feed for tilapia. Background technique [0002] Tilapia is a freshwater farmed fish cultivated by key scientific research in the world's aquaculture industry, and is known as one of the main sources of animal protein in the future. Commonly known as: African crucian carp, non-crucian carp, Vietnamese fish, South Sea crucian carp, etc. Originally referring to the mouth-breathing non-crucian fish species with Mozambique as the model place of origin: Mozambique mouth-breathing non-crucian is now a common name for several species of fish in the genera Cichlidae and mouth-breathing non-crucian. Now it is the key freshwater farmed fish cultivated by scientific research in the world's aquaculture industry, and is known as one of the main sources of animal protein in the future. It usually lives in fresh water, and can also live in salt water with different salinity content, and c...

Problems solved by technology

[0003] The commonly used tilapia feed is often made of wheat bran, starch, bean cake and fishmeal, but in recent years, due to the shortage of fishmeal, the price of fishmeal has soared, which has led to a sharp increase in the cost of aquatic feed

Moreover, the level of feed protein in my country is relatively high, reaching 45%-46%, while that in the Netherlands is 36%-38%. The increase in protein content leads to an increase in cost
