The laying hens in winter are gradually discontinued and enter the rest period. However, the chicken's feathers continue to thicken for safe wintering. According to this natural law and the actual condition of chickens, scientific adjustments should be made to them, and the following two principles should be followed:
First, reduce fine and thick
Winter is the production period of laying hens. The body's demand for nutrients is greatly reduced, and only a small part of the nutrient supply itself is consumed. There is no need to continue to supply high-quality feed during the peak period of egg production. The principle should be “reducing refinement and thickeningâ€, reducing corn, sorghum, dried melon, fish meal, bean cakes, etc., and adding roughage such as bran, sweet potato noodles and cornmeal, and feeding some vegetables to help the leaves (such as cabbage Leaves, celery leaves, etc.) and carrots and other green tubers juicy feed. The proportion is generally 15% fine, 75% rough, and 10% green.
Second, comprehensive nutrition
In order to ensure the growth and health of layer feathers, the nutritional content of the feed must be comprehensive. In diets dominated by concentrated feed, attention should be paid to the supplement of minerals, various vitamins, trace elements, and various amino acids and other feed additives. Because the production of feathers and the physiological and biochemical metabolism of chickens depend on these nutrients. In particular, net-fed, captive, and caged layer chickens are not able to feed on these nutrients due to site constraints. If they do not pay attention to the addition, they are more likely to affect feather growth and chicken health. When supplementing these additives, attention should be paid to the supply of sulfur, gypsum, and hypnosis, each of which can be added in amounts of 2 grams, 3 grams, and 1 gram per day, respectively.
