Abstract

The invention discloses low-tryptophan feed for hybrid chicken. The low-tryptophan feed includes the components as follows: tryptophan, stone powder, Maxus, wheat bran, crushed maize, fish meal, rice bran and traditional Chinese medicine additive. The bulk pharmaceutical chemicals of the traditional Chinese medicine additive further includes: ligusticum wallichii, astragalus, dried tangerine peel, haw, scutellaria baicalensis, medical stone, folium isatidis, turmeric, wolfberry, dodder, white atractylodes rhizome, hedyotis diffusa, angelica, salvia miltiorrhiza and white paeony root. The technical benefits are as follows: concretely, the content of tryptophan meets the normal demand of the hybrid chicken by the optimization on the structure of feed materials, and the waste of tryptophan is reduced to minimum simultaneously when the demand of the hybrid chicken for tryptophan is met; and simultaneously the growth performance can be influenced negatively. The low-tryptophan feed for hybrid chicken greatly improves the survival rate of the chicken, accelerates the growth of the chicken, eliminates the injury of chemical agents to the chicken as well as the side effect of indirectly influencing food safety, adopts fully-new traditional Chinese medicine feed additive and can greatly enhance the slaughtering rate.

Description

technical field [0001] The invention relates to a feed produced by using animals and plants as raw materials, in particular to a low-tryptophan hybrid chicken feed and a preparation method thereof. Background technique [0002] At present, the amount of tryptophan added in broiler chicken diets mainly includes the following aspects: 1. Insufficient tryptophan content. With the massive addition of industrially synthesized lysine and methionine, the nutritional limitation of tryptophan has become increasingly prominent. Tryptophan deficiency can lead to growth retardation, low feed intake, poor stress resistance, and rough coat of animals. Cortamira et al. (1991) reported that tryptophan deficiency can also lead to decreased insulin secretion and decreased protein synthesis. Studies have shown that insufficient tryptophan will cause a reduction in pig feed intake. Burgoon's (1992) study on 10-20 kg piglets showed that the feed intake of piglets in the low-tryptophan (0.13%)...
