The first task of pig farm is to improve the economic efficiency and production efficiency. It is an important measure to select the advanced and economic pig raising equipment which is suitable for the scale and technology of pig farm. At the same time, pig breeding also needs to pay attention to cost saving. For example, how to improve the efficiency of animal feed? Let's introduce it to you.
1、 Selection of improved species
In the production, the breed with high feed utilization rate should be selected, for example, the laying poultry with the same egg production, the heavy weight chicken consumes more materials than the small weight chicken, so the breed with moderate weight should be selected.
2、 Choose suitable nutrition index
Animal nutrition needs to be restricted by a variety of factors, which should be taken into account in the formulation design, especially the variety type, growth stage, production performance, feed material supply and feeding management conditions. The nutrition level is too low to meet the growth and production of animals; if it is too high, it can not be fully utilized, reducing the utilization rate of feed. The nutritional level of the feed to be prepared should be set accurately according to the actual situation, so as to meet the nutritional needs of animals as much as possible, and reduce waste as much as possible. It is not enough to take these factors into account when formulating nutrition indicators. We must consider the sales situation of products. Under different market conditions, different formulation strategies should be selected to ensure maximum benefit.
3、 Rational use of synthetic amino acids
The cost of protein feed can account for about one-third of the total cost of feed. Improving the utilization rate of protein in feed can reduce the level of protein in feed, which is an important way to control the cost of feed. The balance of amino acids in feed protein is the key factor to determine its utilization efficiency. The worse the balance of amino acids in a protein, the lower the utilization of amino acids in animals. The reasonable use of synthetic amino acids in feed to prepare amino acid balanced diet can effectively improve the utilization efficiency of feed, reduce the use of protein raw materials in the diet, not only save the cost of feed, increase the efficiency of breeding, but also significantly reduce the pollution of nitrogen emissions on the environment. For each percentage point decrease in crude protein level, nitrogen excretion could be reduced by 8%. The results showed that the growth performance of pigs had no significant change except for the influence of ketone body properties, when the crude protein level was reduced by 4 percentage points and the appropriate amino acids were added. The reasonable addition of synthetic amino acids to low protein diets or diets composed of low-quality protein feedstuffs can significantly reduce the amount of protein in feedstuffs, reduce costs, and achieve good economic and environmental benefits.
4、 Rational use of enzyme preparation
Enzymes need to enter the digestive tract of animals and act on a specific substrate to play a role. Therefore, when using feed enzyme preparation, it must be suitable for the characteristics of feed materials, the characteristics of the digestive tract of animals, and consider the types of animals, the different growth periods and the differences in digestive physiology, etc., to select the suitable enzymes and the best amount of use.
5、 Feed processing
In the process of feed processing, a series of physical and chemical changes will take place, which will affect the utilization rate of various nutrients in feed and the production performance of animals. After making a perfect feed formula, it is necessary to further improve the utilization ratio of feed nutrition through proper feed processing, and then improve the production performance of livestock and poultry, which is the way to reduce costs and increase benefits.
