Special feed for laying hens in winter

Abstract

The invention relates to the field of feeds for beasts and birds, and particularly relates to a special feed for laying hens in winter. The feed is prepared from the following raw materials in parts by weight: 80-100 parts of rice bran, 30-40 parts of rye bran, 150-160 parts of corns, 45-50 parts of wheat straw, 35-40 parts of sweet potato seedlings, 15-20 parts of white radish sprouts, 8-10 parts of potato peels, 10-15 parts of peanut powder, 15-20 parts of sweet potato leaves, 2-3 parts of porcine bone powder, 1-2 parts of calcium hydrophosphate, 1-2 parts of chicken feather meal, 1-2 parts of black fungus powder, 2-3 parts of semen sesami nigrum powder, 1-2 parts of palm oil, 3-5 parts of gynura crepidioides, a defined amount of salt and 4-5 parts of a phagostimulant. According to the special feed, on the basis of the physiological characteristics of the laying hens in winter, the proportion of a refined feed is reduced in the proportion of the feed, and the content of a course feed is increased; the feed contains abundant mineral substances, various vitamins and trace elements, so that the food intake and the laying rate of the laying hens keep high in winter.

Description

technical field [0001] The invention relates to the field of livestock and poultry feed, in particular to a special feed for laying hens in winter and a preparation method thereof. Background technique [0002] The temperature is low in winter, and the laying hens gradually enter the dormant period, the egg production rate is low, and the feather layer of the laying hens begins to thicken to resist the drop in temperature. At this time, corresponding changes should be made in the feeding of laying hens to maximize The role of feed can reduce the cost of breeding and ensure the safety of laying hens in winter. The feed for laying hens in winter should be comprehensive in nutrition, increase the proportion of roughage, and reduce the content of concentrated feed. However, the existing feed for laying hens ignores the winter of laying hens The nutritional requirements and physiological characteristics of the species, the use of unreasonable feed formulations, lead to serious wa...

[0002] The temperature in winter is low, and the laying hens gradually enter the dormancy period, the egg production rate is low, and the feather layer of the laying hens begins to thicken to resist the drop in temperature. At this time, corresponding changes should be made in the feeding of laying hens to maximize The role of feed can reduce the cost of breeding and ensure the safety of laying hens in winter. The feed for laying hens in winter should be comprehensive in nutrition, increase the proportion of roughage, and reduce the content of concentrated feed. However, the existing feed for laying hens ignores the winter The nutritional requirements and physiological characteristics of the animal, the use of feed with unreasonable formula will lead to serious waste of feed and increase the cost of breeding
