The method comprises the following components in parts by weight: 130-170 parts of calcium hydrogen phosphate, 100-160 parts of stone powder, 100-150 parts of shell powder, 10-40 parts of calcium malate, 20-27 parts of calcium hydroxymethionine, 0.5-2 parts of lactobionic acid, 0.5-2 parts of agaricus blazei and 0.5-2 parts of colostrum alkaline protein, 2-5 parts of hydroxyl vitamin D, 2-8 parts of phytase,2-5 parts of composite enzyme preparation, 2-5 parts of microecological agent, 0.1-0.4 parts of soybean flavone, 0.1-0.4 parts of vitamin K2, 0.5-2 parts of bone collagen, 1-4 parts of polydextrose, 0.5-2 parts of fructo-oligosaccharide, 0.5-2 parts of rhizoma drynariae, 0.5-2 parts of fructus psoraleae and the like. In order to improve the calcium utilization rate, a brand new idea of calcium utilization is provided, that is, three systems of the calcium supplement of the laying hens, that is, a calcium supplementing system, a calcium promotion absorption system and a health system of improving the gastrointestinal.
Description
technical field [0001] The invention belongs to the technical field of laying hen feed, and relates to a premixed feed for improving the bone density and eggshell quality of laying hens and a preparation method thereof. Background technique [0002] Calcium and phosphorus are important minerals for bone metabolism and eggshell formation in caged laying hens, especially calcium has an important impact on the production performance of laying hens. The clinical features of osteoporosis in caged layer hens are mainly manifested as decreased production performance, progressive osteopenia, decreased bone strength, and prone to fractures. Studies have shown that when there is a lack of calcium in the diet, the laying hens will mobilize a large amount of bone calcium to meet the needs of egg production. Long-term feeding of diets lacking calcium, phosphorus or vitamins can lead to atrophy of the parathyroid glands of laying hens and induce osteoporosis of laying hens; the productio...
