Technical Advice on Low Protein Diets

The reduction and substitution of corn and soybean meal in feed and the development of "low-protein ration" are necessary for our country to get rid of the dependence on imported raw materials, and it is also necessary for the vigorous development of the domestic feed processing industry and aquaculture industry. The urgent need to choke the throat.

The Ministry of Agriculture and Rural Affairs stated that it attaches great importance to the research and development, promotion, and application of low-protein diets. Accelerating the promotion of low-protein diets can improve the efficiency of raw material utilization, reduce the amount of soybean meal, reduce soybean import dependence, reduce breeding costs, and reduce nitrogen emissions.

How to develop low-protein diets? Let's take a look at the advice and suggestions of the teachers of Longchang Group's technical service team!

low protein diet recommendations 2 points:

1. The use of raw materials should consider whether there is sufficient supply in the later period to avoid out-of-stocks; the protein design of pig feed is designed according to the current low protein standard, and the design of lysine, methionine, threonine, and tryptophan can be increased by 0.1% according to the standard. ; focus on the balance between amino acids.

2. The cost control is mainly based on the changes of the major raw materials corn, wheat, and soybean meal; the price of wheat is 120-150 yuan/ton higher than that of corn, and the cost is acceptable; attention is paid to the DON content of wheat, and other barley and high grains mainly focus on imports It can be used when the price is similar to that of corn; however, attention should be paid to the initial processing quality of imported raw materials such as barley husks.

At present, the competition for aquatic feed is fierce, which leads to excess nutrients. The excess nutrients contribute very little to aquatic animals. Therefore, it is recommended to:

1. Reducing the protein by 1% can reduce the amount of soybean meal added by 2.5%, supplement amino acids, and reduce the cost of the formula;

2. Reduce the addition of 0.3-0.5% fat, and add functional additives that promote fat digestion, absorption, and utilization, such as bile acids, which can not only protect the liver and protect the liver but also achieve the same effect as before. Do "subtraction" for feed factory farmers to reduce the cost burden; do "addition" for aquatic animals to improve growth, immunity, and weight gain!

In low-protein diets, it is necessary to revise the enterprise filing standards, revise the crude protein index, do a good job of enterprise operation safety, and reduce the protein level. It is necessary to increase the energy level accordingly. Blindly reducing the protein will affect the product effect.

1. To ensure protein digestibility, use additives that can improve protein digestibility (such as Yolanbao) as supplements.

2. Do a good job in evaluating the level of digestible protein of the product, reduce the crude protein, stabilize the digestible protein or gradually reduce the gradient test to ensure the stability of the product efficacy.

3. Select high-protein energy raw materials (such as wheat, palm meal, etc.) to partially replace corn, which not only reduces costs but also saves the amount of protein raw materials (soybean meal, etc.).

Use new protein raw materials, such as guar meal, lupin, etc. Pretreatment, enzymatic hydrolysis, fermentation, puffing, and other processes for some low-priced protein raw materials to improve the protein value of low-priced protein raw materials.

Recommendations for broiler low protein diets are 2 points:

1. For corn and soybean meal reduction and substitution, different reduction or replacement technical solutions should be recommended for business entities with different production forms. Specifically, low-protein feed formulas are promoted in one-stop enterprises, and corn-soybean meal-free formulas are promoted in commercial feed factories.

2. The low-protein formula of broilers must pay attention to drinking water (low-protein formula will cause lower drinking water), amino acid nutrition in the low-protein formula is very important, especially threonine.
