Embodiment 1

[0017] A low-protein and amino acid-balanced feed for yellow-feathered brood hens during laying period, containing 705g of corn, 130g of soybean meal, 50g of wheat bran, 70g of stone powder, 5.1g of zeolite powder, 2.4g of DL-methionine, and 2.4g of L-threo Amino acid 2.5g, lysine hydrochloride 2.9g, isoleucine 1.3g, L-valine 1.3g, calcium hydrogen phosphate 18g, salt 1.5g, additive premix 10g. The feed formulated according to the above components contains 13% crude protein, 2.72MCal / kg energy, 2.97% calcium, 0.41% available phosphorus, 0.79% lysine, 0.45% methionine, 0.59% isoleucine, and 0.69% valine , Threonine 0.55%.

[0018] The preparation process is as follows: Firstly, the small amount of small materials such as lysine hydrochloride, DL-methionine, L-threonine, isoleucine, L-valine, calcium hydrogen phosphate, salt, premix, etc. Blend until smooth in a small blender.

[0019] Then put corn, soybean meal, wheat bran, stone powder, zeolite powder and the previously mix...

Abstract

The invention discloses a low-protein amino-acid-balanced feed for yellow broiler hens at a laying period and an application of the low-protein amino-acid-balanced feed, and belongs to the field of feeds. Each kilogram of the feed comprises 13-15% of gross protein, DL-methionine, L-threonine, L-lysine monohydrochloride, isoleucine and L-valine monomers are added to maintain amino acid in the feedbalanced, and rest nutrient levels all refer to the recommended level of NY / T 33-2004 hen raising standard. The low-protein amino-acid-balanced feed does not have any negative effects on the production performance, the egg productivity, the egg quality and the incubation performance of the yellow broiler hens and the growing performance of progeny chickens, can effectively reduce the content of urea nitrogen and uric acid in plasma of the yellow broiler hens, and the nitrogen discharge quantity of excrement and urine. Therefore, according to the feed, protein feeds can be saved, nitrogen pollution can be reduced, and besides, normal reproductive performance and egg quality of the yellow broiler hens can be guaranteed.

Description

technical field [0001] The invention belongs to the field of feed, and relates to a low-protein amino acid balanced feed for yellow-feathered broiler hens during laying period and an application thereof. Background technique [0002] In recent years, the price of feed raw materials in my country has been rising, especially the dependence on protein feed imports is increasing, and the environmental nitrogen pollution caused by animal husbandry is becoming more and more serious. Therefore, the use of low-protein feed in production has important practical significance. However, if the dietary crude protein level is too low, even the supplementation of synthetic amino acids will have adverse effects on animal performance. In production practice, formulating diets based on digestible amino acids and ideal protein patterns has been implemented, and the conventional technology based on crude protein is replaced by new technologies and the addition of crystalline amino acids. Yello...
