Feed for improving egg yield of laying hens, preparation process and feeding method of feed

Abstract

The present invention discloses a feed for improving the egg yield of laying hens, a preparation process and a feeding method of the feed. The feed consists of 90-93% of a basic feed, 5-7% of dried traditional Chinese medicine residue powder and 2-3% of a functional additive. The functional additive comprises the following components in parts by weight: 0.02-0.03 part of choline chloride, 0.5-0.7part of resveratrol, 0.06-0.1 part of dihydropyridine, 2-3 parts of soybean isoflavones, 3-5 parts of bee pollen, 1.4-2.6 parts of glycyrrhizin, 3-4 parts of beta-carotene, 6-8 parts of linoleic acid,0.8-1.2 parts of iron methionine, 0.8-1 part of lysine and 1-2 parts of tryptophan. The feeding method is as follows: 1-4-week chicks are fed 6-8 times every day, and every time the feeding amount is4-5g per chick; 5-6-week chicks are fed 4-6 times every day, and every time the feeding amount is 13-15g per chick; and 8-20-week growing chickens are fed 3 times every day, and every time the feeding amount is 60-80g per chickens. The feed not only provides abundant nutrient substances for laying hens in egg-producing period, but also stimulates the secretion and expression of estrogen in the body of laying hens, performs exogenous supplement of natural plant estrogens, and prolongs the egg-production peak.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a feed for improving egg production of laying hens, a preparation process of the feed and a feeding method thereof. Background technique [0002] After entering the peak egg production period, after more than 100 days of continuous egg production, the health status of the laying hens is not as good as that in the early and middle stages of egg production, the level of estrogen drops, and the egg production begins to decrease. The production of laying hens has been reduced, and even moulting has stopped production. In the prior art, most of the feed structure is improved by increasing the calcium-phosphorus ratio and protein content to provide sufficient energy and nutrition for laying hens and restore physiological functions. Hormone levels cannot maintain the state of continuous high production during the peak egg production period. Therefore, providing a fe...

Problems solved by technology

In the prior art, most of the feed structure is improved by increasing the calcium-phosphorus ratio and protein content to provide sufficient energy and nutrition for laying hens and restore physiological functions. Therefore, providing a feed that continuously stimulates the secretion of estrogen, maintains a stable estrogen level, and has comprehensive nutrition and high protein is an important way to promote the high yield of laying hens

[0003] The patent with the application number CN201710533433.7 discloses a method for making biologically fermented feed for laying hens. Two kinds of bacillus are used to ferment the feed to increase the content of small molecule polypeptides and amino acids in the feed and improve the effective utilization of protein, but it cannot Promote and stimulate the secretion of estrogen in laying hens, but cannot solve the problem of lower estrogen levels after the peak laying period, and it is difficult to maintain high egg production rate of laying hens for a long time
