Feed for increasing color grade of yolks and improving laying rate of laying hens

Abstract

The invention discloses safe feed for increasing the color grade of egg yolks and improving the laying rate of laying hens and preparation method of the feed. The feed is prepared from the following components in parts by weight: 40-65 parts of corn, 8-20 parts of soybean meal, 5-12 parts of corn protein powder, 3-10 parts of wheat middling, 5-10 parts of cottonseed meal, 3-6 parts of rapeseed meal, 2-6 parts of mountain flour, 3-10 parts of calcium hydrophosphate, 0.5-1.5 parts of soybean oil, 0.5-1.2 parts of trace elements, 0.5-1.2 parts of vitamins, 0.2-0.4 part of table salt, 0.1-0.3 partof amino acid and 2-4 parts of a toner. The feed disclosed by the invention applies the natural toner on the basis of providing necessary nutrient substances for vital activities of the laying hens,thereby increasing the color grade of the yolks and improving the quality of eggs, and meanwhile, the laying rate of the laying hens is improved; breeding profit is increased; the healthy developmentof China's poultry industry is facilitated; a very good application prospect is realized.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a feed for increasing egg yolk grade and laying hen laying rate, and a preparation method and application thereof. Background technique [0002] Eggs are delicious and cheap, and have high nutritional value. Every 100 grams of eggs contain about 14 grams of protein, which is an important source of protein. Eggs contain fat, lecithin, vitamins and a variety of trace elements needed by the human body, and contain a variety of amino acids necessary for the human body. The composition is similar to that of human protein, and it is an ideal natural food. The protein content in the egg yolk is 1.5%, and the fat content is 33.3%. The egg yolk is also rich in calcium, phosphorus, iron, vitamin A, vitamin D and B vitamins. The iron content of the egg yolk is 20 times higher than that of the protein. Egg yolk is the main carrier of egg flavor substances, an important f...
