Application Status and Development Trend of Feed Protein Sources

With the rapid development of large-scale farming, the market demand for feed continues to expand and demanding. This makes the competition in the feed industry more intense. In the composition of feed, protein source is a vital and necessary part. The manufacturer's reasonable choice of protein source largely determines the market competitiveness of the product. This article briefly reviews the application status and development trend of common protein sources at present, in order to provide a certain reference value for the selection of feed protein sources.

1 Animal protein source

1. Fish meal 65%

Fish meal has many unique advantages such as high protein content, complete essential amino acids, rich nutritional factors, easy digestion and absorption by animals, and good palatability. It is currently the most widely used animal protein source in the field of farming. Even so, fish meal has its disadvantages that cannot be ignored:

(1) The price of fish meal is quite high, and with the decline of global fishery resources, the output of fish meal has been declining year by year. Most of my country's fish meal relies on imports, so the price and quantity of fish meal have a great impact on my country's aquaculture industry;

(2) During the processing and storage of fish meal, biogenic amines (such as cadaverine, spermine, spermidine, putrescine, etc.) will be produced, which will have an adverse effect on animal growth;

(3) Since the raw materials for processing fish meal contain high-phosphorus substances, the phosphorus content of fish meal is generally high, which will cause harm to animal growth and its environment (such as eutrophication of aquaculture water bodies);

(4) Recently, salmonella has been repeatedly detected in imported fish meal, which has gradually attracted people's attention.

1.2 Meat meal and meat and bone meal

my country has abundant animal waste resources, but the utilization rate is very low. At present, domestic enterprises are increasing the development and utilization of these resources and processing them into meat meal or meat and bone meal. Meat meal and meat and bone meal have a high crude protein content (generally above 50%). In their amino acid composition, glycine, arginine, and proline are high, but tryptophan is very low. Tryptophan is an important limiting amino acid, which is also one of the shortcomings of meat meal and meat and bone meal. Meat meal has high crude fat and low crude ash, while meat and bone meal is the opposite. The salt content of meat meal and meat and bone meal is unstable and varies greatly. When processing feed, their dosage and salt content must be fully considered to avoid excessive salt in the finished product, causing livestock and poultry poisoning......
