First, the rational use of feed additives
In recent years, research on feed additives continues to advance. More and more shows its importance. Adding supplemental amino acids, vitamins, minerals, and insect repellent health care drugs to the basal diet can not only improve the full price of the diet, but also have a significant effect on reducing disease, promoting growth and improving feed utilization efficiency of livestock and poultry. .
Second, ensure the supply of protein feed
Protein feed is an indispensable nutrient for the growth and development of livestock and poultry. For monogastric animals, methionine and lysine are indispensable raw materials for the production of compound feed.
Third, the implementation of scientific feed restriction technology
This method is based on the different growth stages of livestock and poultry and different production purposes, through the adoption of changes in feed or change the feeding time, so that livestock and poultry to achieve the expected weight requirements to ensure high performance of livestock and poultry.
Fourth, do a good job of storage management
Poorly stored feeds are prone to hygroscopic, moldy or worm-eaten diseases. The value of feed for molds and feeds is not only reduced but also prone to poisoning, resulting in illness or death of livestock and poultry. If the feed is stored for a long time, the nutrients will be reduced due to the deterioration of the fat even though it is not mildewed, and vitamins A, D and E are also likely to be reduced in effectiveness due to oxidation. Therefore, the purchase of feed should not be too much, the feed must be purchased to avoid light, ventilation and moisture, so as not to cause mildew loss, improve feed utilization.
Fifth, select good breeds and use heterosis
The higher the productivity of livestock and poultry, the lower the consumption of materials and the lower the cost. In recent years, the cultivation and introduction of improved varieties has had a significant effect on saving feed and increasing feed utilization efficiency. For example, the number of dairy cows in the world is decreasing year by year. Although the amount of milk that can be produced is increasing, the advantage of using hybrids is another effective method of saving feed. Generally, a cross-breeding pig can increase daily weight gain by 10-30% and save about 10-15% of feed.
