Winter and spring chicken feed add good manganese sulfate

Effect of Body Development Characteristics on Production Performance of Egg Breeder

Measure the body development standards for egg breeders with skeleton as the first limiting factor, body weight as the second limiting factor, and production as the specific indicators. The growth rate of chicken's bones and body weight is different. The bones grow rapidly within 10 weeks. Skeletons of 8 weeks old chicks have been completed 75%, and 12 weeks old have completed more than 90%, while the weight reaches the highest point at 36 weeks old. The development of body shape has a direct impact on the production performance. For birds with long-term weight and lighter weight, the egg weight is small at the early stage of laying, and the egg production rate rises slowly. In the case of egg production or serious prolapse of the anus, the rate of death is high. If the length and weight of the animal are not up to the standard, it means that the brooding has failed to grow and the production time is prolonged. At least 1 to 2 weeks may be postponed and 3 to 3 may be postponed. In 4 weeks, the egg production peaks of egg breeders were not up to standard, so that the production volume was reduced and the hatching plan could not be arranged, which had a great impact on economic efficiency.

Body shape development control measures

According to the developmental characteristics of body shape, it is necessary to focus on long-term growth before 8 weeks of age and growth of 8-12 weeks old pupal length and body weight in the rearing and management, and strive to make the pecking length of the fowls more than 90% evenly. Uniformity of more than 80%.
Winter to spring is the hatching season of chickens. During this period, it is necessary to pay attention to adding proper amount of manganese sulfate to the chicken's feed. Because manganese is an activator of many enzymes, it plays an important role in the growth and reproduction of chickens.

In winter and spring, there is a lack of green feed, chickens are mainly seeded feeds, and seeded feeds have a particularly low manganese content, so chickens are susceptible to manganese deficiency in winter and spring. When the chicken is deficient in manganese, bone development is not normal, and the leg bones are short and curved, and the diseased chicken is limp. The disease occurs in 3 to 6-week-old chicks; the second is the chicken embryo in the egg malformations, the occurrence of thicker and shorter legs, the wings also become shorter, head deformity, similar to the ball, embryonic dysplasia, and thus reduced hatching rate. Therefore, special attention should be paid to the supply of manganese from winter to spring. Laying hens, breeders, and chicks can be added at a rate of 8 grams of manganese sulfate per 100 kilograms of feed to meet demand.
