Problems solved by technology

The egg production rate has decreased, and the quality of the eggs has also decreased. Chickens that are not suitable for breeding are eliminated layer hens. The price of eliminated chickens will be cheaper. During the process of raising chickens, if chickens with diseases or poor health are found, they should also be eliminated. At present The culled layer hens are generally sold as broiler chickens, but the meat quality and nutritional value of culled chickens are significantly lower than those obtained from normal breeding, so it is difficult to sell at a higher price and cannot bring better economic benefits to farmers

Abstract

The invention relates to the technical field of poultry feeds, in particular to a feed additive for spent hens. Each part of feed additive is prepared from compounding the following raw materials in parts by weight: 3 to 5 parts of round cardamon seed, 1 to 1.5 parts of venerupis philippinarum leavening and 3 to 5 parts of lettuce enzymatic hydrolysate. The obtained feed additive is harmless to the hen bodies, and has the advantages of freeness from pollution and freeness from residues; when the feed additive is added into a spent hen feed in a weight ratio of 3 to 3.5 percent, physiological regulation of the hen bodies can be realized, and the internal secretion hormone level of the spent hens is increased, so that the laying performance of the hens is reactivated.

Description

technical field [0001] The invention relates to the technical field of poultry feed, in particular to a feed additive for weeding out laying hens. Background technique [0002] Eliminated chickens refer to chickens that are screened out by chicken farms and cannot reach a certain standard at a certain age, and are eliminated, referred to as eliminated chickens. Elimination of chicken points: layers, broilers, roosters. The egg production rate has declined, and the quality of the eggs has also declined. Chickens that are not suitable for breeding are eliminated layer hens. The price of eliminated chickens will be cheaper. During the process of raising chickens, if chickens with diseases or poor health are found, they should also be eliminated. At present Eliminated layer hens are generally sold as broiler chickens, but the meat quality and nutritional value of culled chickens are significantly lower than those obtained from normal breeding, so it is difficult to sell them at...
