[0032] This embodiment provides a feed additive for improving the laying performance and egg quality of laying hens, including 1.25 parts of 65% lysine sulfate, 1 part of arginine, 0.53 parts of cystine hydrochloride, and 0.2 parts of threonine And 0.02 parts of DL-methionine, 97 parts of dried black soldier flies.

[0033] The method for improving the laying performance and egg quality of laying hens through the feed additive test includes: mixing the above feed additive and chicken feed at a weight ratio of 6:94 to obtain a compound feed; 384 laying hens are placed in a fully enclosed chicken house , using 4-layer ladder cages, 8 chickens per cage, automatic environmental control and light, the light time reaches 16 hours / day, the temperature is about 22°C, and the relative humidity is 50-90%. During the test period, the chickens had free access to food and water, fed twice a day (09:00 and 15:00), picked eggs and cleared feces once each, and underwent routine immunization a...

Embodiment 3

[0035] This embodiment provides a feed additive for improving the laying performance and egg quality of laying hens, including 1.25 parts of 65% lysine sulfate, 1 part of arginine, 0.53 parts of cystine hydrochloride, and 0.2 parts of threonine and 0.02 parts of DL-methionine; 97 parts of black soldier flies are replaced by bran.

[0036] The method for improving the laying performance and egg quality of laying hens by the feed additive test comprises: using the above-mentioned feed additive and chicken feed in a weight ratio of 3:97 to obtain a compound feed; 384 laying hens are placed in a fully enclosed chicken house, Adopt 4 layers of ladder cages, 8 chickens per cage, automatic environmental control and light, the light time reaches 16 hours / day, the temperature is about 22 ℃, and the relative humidity is 50-90%. During the test period, the chickens had free access to food and water, fed twice a day (09:00 and 15:00), picked eggs and cleared feces once each, and underwent...

Abstract

The invention provides a feed additive for improving the egg laying performance and egg quality of laying hens and an application method of the feed additive. The feed additive comprises compound amino acid and dried black water gadflies, and the compound amino acid comprises 65% L-lysine sulphate, arginine, cystine sulphate, threonine and DL-methionine; the mass percent of the dried black water gadflies in the feed additive is 94-97%. The method for improving the egg laying performance and egg quality of the laying hens comprises the steps that the feed additive and a feed are mixed accordingto a weight ratio of (3-6):(94-97) so as to obtain a compound feed; the laying hens in the later period of the egg laying peak are fed with the compound feed twice every day, each laying hen is fed with 50-55 g of the compound feed, the environment illumination time keeps 12-16 hours/day in the feeding period, the environment temperature is 20-25 DEG C, and the relative humidity is 50-90%. According to the feed additive, the descending magnitude of the egg laying rate and salable product egg rate in the later period of the egg laying peak can be lowered, the descending rate of the egg qualityis lowered, and the egg laying period is prolonged.

Description

technical field [0001] The invention belongs to the technical field of feed additives for livestock and poultry, and in particular relates to a feed additive for improving egg production performance and egg quality of laying hens and an application thereof. Background technique [0002] With the maturity of feeding technology, laying hen farming has entered the stage of small profits. How to efficiently improve the production performance and egg quality of laying hens can directly affect the economic benefits of production. The laying performance of laying hens mainly includes the laying age of the laying hens, the peak laying period and its maintenance time, the dead rate of laying hens and the rate of genuine eggs. Among them, the peak egg production period and its maintenance time determine the production performance and egg quality in the late egg production period, and even the egg production efficiency and egg production volume of the laying hens throughout the egg pro...
