Prevention and treatment of chicken rickets
During the growth and development of chickens, especially during the low temperature season, if the metabolism of minerals, especially calcium and phosphorus, in the body is destroyed, it will cause abnormal bone tissue growth and form a nutritional disease. Adult chickens are usually called osteomalacia. Chicks are usually called rickets. Symptoms The diseased chickens are mainly characterized by poor growth, loss of appetite, plumage, and soft-bending of the bones. The joints between the soft ribs and hard ribs are round-pinched and hard-sectioned. The chest is flat and flat, protruding to both sides. Severe mouth is as soft as rubber, it is difficult to feed, the pain in both limbs cannot stand, and most of the bed is lying. Both chicks are curved or X-shaped curved, spine bent, chickens are weak. Egg laying rate decreased. Prevention First, to give the chicken enough calcium, phosphorus and vitamin D, it is best to feed full-priced compound feed. Second, give 16 hours of light every day. At the same time, gravel is supplemented to increase the digestibility of feed for chickens. Third, the amount of feeding some green feed. Treatment I. Diseased chickens should be promptly increased dietary calcium and phosphorus ratio. Under normal circumstances, the content of calcium and phosphorus in the diet: 0.9% of chicks, 1.1% of growing chickens, 3.1% to 3.5% of laying hens, and about 0.9% of broilers. Calcium and phosphorus ratios: 21:1 for chicks, 23:1 for growing chickens, and 7:1 for laying chickens. Special attention must be paid to vitamin D or cod liver oil to promote chicken absorption of calcium and phosphorus. Under normal circumstances, vitamin D2000 international units are added per kilogram of feed, and cod liver oil is used for 1 to 2 ml per bird per day. Second, add bone meal and other substances in the diet. Bone meal can account for 1% to 2% of the diet.
