Problems solved by technology

[0003] The object of the present invention is to provide a tilapia feed according to the problems of low protein efficiency and amino acid imbalance in the existing tilapia feed, which lead to high breeding costs, excessive ammonia nitrogen discharge, and huge pollution of the water environment. , the amino acid pattern of the feed is balanced, which reduces the pollution of the breeding water
The use of this feed can effectively solve the problems of low protein efficiency and serious environmental pollution in the current tilapia farming process. It not only improves the industrial profit, but also reduces the pollution and damage to the water environment during the farming process, and realizes the Sustainable development of non-fish farming industry

Abstract

The invention discloses an amino acid pattern balanced type tilapia mossambica fodder. The fodder comprises the following raw materials by weight percent: 28-40% of a protein source raw material, 2-9% of a fat source raw material, 35-55% of a carbohydrate source raw material, 0-3.0% of compound vitamin, 0-3.0% of compound mineral salt, 0-0.3% of an antioxidant, 0-4% of an adhesive, and 0-13% of cellulose. The tilapia mossambica fodder can meet the requirement of tilapia mossambica on nutrition for optimal growing, effectively solves the problems of poor feed conversion rate and poor protein efficiency caused by unbalanced amino acid of a mixed feed in an existing tilapia mossambica breeding process, not only improves industrial profits, but also lowers the pollution and the damage to an aquatic water environment in the breeding process, and realizes the sustainable development of the tilapia mossambica breeding industry.

Description

technical field [0001] The invention relates to the field of tilapia feed, in particular to a tilapia feed with balanced amino acid patterns. Background technique [0002] Tilapia is an important freshwater farmed fish in my country. Because of its fast growth, high catch rate, no intermuscular spines, and delicious meat, it has become the main species of freshwater aquaculture in southern my country. However, as the prices of global energy and food resources have continued to soar in recent years, the farming benefits of farmers have become increasingly low, resulting in serious restrictions on the high-density and intensive farming of tilapia. The main reason is that the amino acid pattern of the feed currently used in production is unbalanced, resulting in low feed conversion rate, poor protein efficiency, and high feed cost. At the same time, due to the low feed efficiency, the ammonia nitrogen content discharged into the aquaculture water exceeds the standard, resultin...
