Corn gluten meal：
It is a by-product of deep processing of corn. The product is golden yellow in color and in the form of granule powder. It has the function of promoting disease resistance to livestock. It is an excellent additive for animal husbandry and feed industry. It can extract natural yellow pigment and rich in amino acids.
Corn protein meal has high protein content and rich amino acids. It can be used to replace protein feed such as soybean cake and fish meal in the feed market where soybean cake and fish meal are in short supply. The laying rate can be increased about 15% by using corn protein powder as the main feed. It can prevent and cure chicken cartilage disease and other diseases, play the role of health care and growth promotion, and improve egg protein quality.
In cattle industry, using corn gluten powder as concentrate can make some protein which can't be digested by rumen better digested and absorbed in small intestine. Corn gluten meal contains linoleic acid, which can promote the fat metabolism of chicken and the polymerization of essential amino acids.
Corn gluten meal improves the chroma of broiler. Although the chroma of broiler skin has nothing to do with its nutritional value, influenced by traditional culture, consumers and breeders still regard the chroma of broiler as one of the main indexes to measure the quality of broiler products, which directly affects the price and demand of broiler market. Broilers can't synthesize lutein by themselves, they can only get it from feed. At present, in order to obtain ideal skin color, it is generally to add chemical synthetic colorants such as garlicin red and garlicin yellow in the feed of broilers. The price of such colorants is high, and the cost of feed will be increased after they are added, and they will remain in livestock and poultry. The content of lutein in corn gluten meal is as high as 90-180mg / kg, which is more than 5 times as much as that of yellow corn. It can be absorbed effectively, make the egg golden, and make the chicken skin yellow. The price of corn gluten meal is close to that of soybean cake. In view of this, corn gluten meal and arsanic acid can be used to replace the colorant synthesized by chemical industry to improve the colority of broiler.
2.5% corn gluten powder and 90 mg / kg arsanic acid were added to the diet of the experimental group, 100 mg / kg gallin red was added to the diet of the color additive control group, and no coloring substance was added to the diet of the blank control group. Results the color level of the experimental group and the color additive control group was significantly higher than that of the blank control group. There was no significant difference between the experimental group and the color additive control group in the increase of gum color level, and the meat of the experimental group The color of chicken shank is dark yellow, and its appearance conforms to people's consumption habits. From the perspective of the color winning effect of slaughtered broilers, the effect of adding corn protein powder is close to that of adding gallin red, which is significantly higher than that of the control group; the effect of natural lutein in feed is slightly worse than that of chemical synthetic colorant, but by adding arsanic acid, it can promote the metabolism of the body and improve the utilization and deposition rate of lutein in feed, thus changing the broilers The coloring degree of epidermis has obvious effect.
