What is the feed standard for broiler breeders?

Meat hens lay 150 eggs a year? 190, genetic characteristics are easy to be obese, which is not conducive to laying eggs. Therefore, measures to restrict the cultivation of Chinese characters are often taken. Feeding standard nutrition level of broiler breeders is lower than that of laying hens. In order to control the weight, broiler breeders should take restrictive measures in the breeding and laying stages of backup chickens. Therefore, it is necessary to refer to the typical standard weight arrangement rules of each breed and control the food intake in order to obtain successful feeding effect.

Standard for nutritional safety of feed. Feed companies must attach great importance to product quality when producing compound feed in order to maintain its reputation. When users often find that the egg production rate is declining, the growth is slow, the feathers fade or lose luster, the first thing that comes to mind is the quality of feed. Although the feed factory strictly implements quality control, it can produce 80 yuan in each shift every day. There are many raw materials, many sources and varieties of raw materials for 240 t supporting feed, so it is inevitable that sampling is uneven and omitted.

Feeds with the same name are also very different. For example, corn contains protein 7. 5% ? 9。 5%, containing lysine 0. 2% ? 0。 26%, and corn often accounts for 60% of the compound feed? 70%, which has a great influence on the nutritional level of feed. General feed mills don't have the equipment and technical force to determine lysine and methionine, and calculate them completely according to the feed composition table and the nutritional requirements standard of the grain to be produced. Even if the calculation is very accurate, there may be times when the amino acid content can't reach the standard.

If the product is judged unqualified after investigation by the quality inspection department, it will affect the reputation of the company. Therefore, some insurance methods are often used to calculate the feed formula by choosing a lower value in the feed composition table and increasing the safety of the feed standard by 10%, which not only ensures the production performance of the compound feed, but also avoids being judged as inferior products by the quality inspection department. Anyway, the cost is added to the cost and borne by the user.
