Corn gluten meal is a by-product of the purification of corn grain by the food industry for the production of starch or the wine industry. It is rich in protein nutrients and has a special taste and color. It can be used as a feed and compared with fish meal and bean cake commonly used in the feed industry. The obvious advantages are high feed value, no toxic and harmful substances, no reprocessing, and direct use as protein raw materials.
Chinese name: Corn protein powder Foreign name: corn gluten meal
The different nutrient composition of corn gluten meal produced by different uses and different production processes directly affects the effective utilization rate and economic benefits of feed formulation. Corn protein powder produced by the pharmaceutical industry contains up to 60% protein. Its protein content is 21% and 3.7% higher than that of soybean cake and fishmeal, respectively. It is a feed material with high protein, and crude fiber content is 3.9% lower than that of soybean cake. The fat content of medical corn protein powder is higher than that of soybean cake and corn seed. After formulated into feed, dietary fat has a high content of fat, which helps to reduce amino acid oxidation and produce more body proteins, but also inhibits the conversion of glucose and other precursor substances into fats; at high temperatures, it is also conducive to energy ingestion, Reduce the body heat consumption of livestock and poultry and reduce heat stress.
Tetac corn protein meal is a by-product of the wine industry. It has a low protein content and a high crude fiber content. Its nutritional value is not as high as that of medical corn protein meal. However, due to the presence of unknown growth factors, it can significantly increase animal production performance when added to the diet. .
High protein content of corn gluten meal, rich in amino acids, can be used as a substitute for soybean meal, fish meal and other protein feeds in the feed market where soybean cakes and fishmeal are in short supply. Maize protein powder is rich in nutrients, does not contain toxic and harmful substances, does not require reprocessing, and can be directly used as a protein material, and is a feed material with a higher feed value.
1, cattle feed
The use of corn gluten meal as a concentrate feed can enable better digestion and absorption of some proteins that cannot be digested by the rumen in the small intestine. Corn gluten contains linoleic acid, which promotes lipid metabolism in chickens and promotes the polymerization of essential amino acids.
2, pig feed
The protein content of corn gluten meal is directly related to the apparent digestive energy value of pigs, and the energy or protein ratio is suitable or the raw materials that are in balance with essential amino acids and non-essential amino acids have high energy digestibility. Proteins are added to the basic feed of pigs. Different levels of corn gluten meal (CP: 52% in northeastern, 47.4%, 32% in Beijing), with added weights of 20%, 25%, and 30%, respectively, were measured for digestive energy of pigs. The test results showed that the content was 32% coarse. The apparent digestive energy of protein zein powder is higher, which may be due to its appropriate energy and protein ratio.
3, chicken feed
Egg-based egg-based chickens can increase the egg production rate by about 15%. It can prevent and treat chicken’s cartilage disease and other diseases. It plays a role of health promotion and growth, and is beneficial to improving the egg protein quality.
4, broiler coloring
Although the degree of coloration of the broiler’s epidermis has nothing to do with its nutritional value, due to the influence of traditional culture, the majority of consumers and breeders still regard broiler coloring as one of the main indicators to measure the quality of broiler chickens and directly affect the price of the broiler chicken market. And demand.
Broilers cannot synthesize lutein by themselves and can only be obtained from the feed. In order to obtain the ideal skin color, chemical colorants such as galactin and galacto yellow are commonly added to the broiler feed. Such colorants are sold. The price is higher. After the addition, the feed cost is increased and remains in the livestock and poultry. The content of lutein in corn gluten meal is as high as 90-180mg/kg, which is more than 5 times that of yellow corn. It can be effectively absorbed, and it can make the eggs golden yellow and the chicken skin yellow. The price of corn gluten meal is close to the price of soybean cake. In view of this, zein powder plus azan acid can be used instead of chemically synthesized colorants to improve the coloration of broilers.
Add 2.5% corn gluten meal and 90 mg/kg azasanolic acid to the diet of the experimental group, and add 100 mg/kg gallish red to the diet of the colorant control group. No coloring is added to the diet of the blank control group. In the test group, the control group and the colorant control group had significantly higher win and color levels than the blank control group. The difference in the color scale between the test group and the colorant control group was not significantly different. The coloration of the broiler in the test group was dark yellow and the appearance was In line with people’s spending habits. From the effect of slaughter of broilers, the effect of adding corn gluten powder is similar to that of adding celecoxib, which is very significantly higher than that of the control group. The effect of natural lutein in feed is better than that of chemical synthetic coloring agents. The effect is slightly worse, but by adding aphanelic acid, it promotes the metabolism of the body and improves the deposition rate of the lutein used in the feed, thus changing the degree of pigmentation of the broiler epidermis.
