Method for preparing feed for laying hens in growing periods

Abstract

The invention discloses a method for preparing feed for laying hens in growing periods. The method includes weighing, by weight, 60-62 parts of corns, 20-25 parts of feather meal, 18-24 parts of bran, 0.5-1 part of vegetable oil, 0.3-0.6 part of table salt, 0.1-0.5 part of multi-vitamins, 0.3-0.6 part of trace elements, 1.5-2.5 parts of gamma-aminobutyric acid and 8-10 parts of traditional Chinese medicine micro-ecological micro-capsules; smashing the corns and the bran and then adding remaining raw materials into the corns and the bran to obtain mixtures; granulating the mixtures at the high temperatures and cooling the mixtures to obtain the granulated feed. The method has the advantages that obvious weight gain effects can be realized by the feed for the laying hens in the growing periods, the feed has a high benefit on the year-on-year basis, the quantities of beneficial floras in the intestinal tracts of the laying hens can be increased, reproduction of harmful bacteria in the intestinal tracts of the laying hens can be controlled, immune functions of the laying hens can be improved, the anti-stress capacity and the disease resistance of the bodies of the hens can be enhanced, group prevention administration can be reduced, and the laying hens are high in growing survival rate; the concentration of indoor ammonia gas can be obviously reduced, and the quantities of mosquitoes and flies can be reduced to a great extent; stress can be reduced, indoor environments can be protected, and the uniformity of the grown hens can be obviously improved; the laying start ages of the laying hens can be respectively brought forward by 3-5 d as compared with comparison groups, the weights of eggs can be respectively increased by 2-4 g, feed can be saved, the cost can be lowered, and accordingly the breeding economic benefit can be increased.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a preparation method of feed for laying hens in the growing period. Background technique [0002] With the development of laying hen breeding industry, the requirements for laying hen feed are getting higher and higher, especially laying hen rearing feed is a key stage in the whole laying hen production cycle, and the growth and development of chicks are directly related to the uniformity and quality of rearing chicken Egg production rate, thereby affecting the production performance of hens. The research showed that the body weight at 10 weeks old was positively correlated with egg production persistence, the correlation coefficient was 0.82; it was positively correlated with the survival rate at 60 weeks old, and the correlation coefficient was 0.71. Layer chicks moult for the first time at the age of 4-10 weeks. At this stage, the chicks grow rapidly. By the age of 8...
