Should I feed corn gluten feed?

There is no doubt that corn gluten feed is a type of feed that is used by many farmers, so many novice farmers are using it. Is this correct? of course not! Everything has its own particularity, not for all situations, as is corn gluten feed. If you are confused about corn gluten feed, read this article carefully and give you the answer.

This article contains the following points:

  • Introduce the nutritional value of corn gluten.

  • Corn gluten application range

  • Potential constraints



1、Introduce the nutritional value of corn gluten.

Corn gluten feed is the main feed ingredient in ruminant diets, especially beef and cows. Wet corn gluten feeds contain 40 to 60%, while dry products contain about 88%. The feed is a medium-high source of protein: it contains about 20-25% protein, more than grain and mill by-products, but lower than corn gluten meal, vinasse and most oil mash. The feed is richer than cell wall components (6-10% crude fiber, 31-49% NDF, 8-13% ADF and 1.2% low lignin content), which often limits its use in pigs and pigs. . Poultry diet. The crude fat content is usually less than 4%. The feed contains relatively high and variable amounts of residual starch, from 11% to over 30% DM. The ash content is also important (about 7%).

The composition of the feed is affected by the proportion of the soaking liquid, which contains more energy and protein than the bran. The ratio of steep liquid to bran is typically 1:3 to 2:3, and differences in nutritional value between products with low or high levels of steep liquid may be important. The color of the feed varies from tan to dark brown, depending on the amount of steep liquid, drying temperature and drying time. Dry the feeds typically darken as drying temperatures or times increase. Very dark corn gluten feeds with a "burnt" odour may be thermally damaged and protein digestibility may be reduced.


2、Corn gluten application range

  •  Beef cattle

Corn gluten feed is a good source of protein, energy and phosphorus for beef cattle. The feed contains low levels of starch. Many of the benefits of these by-products are that their energy content comes from high digestive residual fiber content. The fiber component facilitates reduction of acidosis in high grain rations and aids in fiber digestion when formulated with high forage feed. The feed is available in dry or wet form.

  •  sheep

In high-concentration mutton diets, up to 50% of the diet contains different forms of the feed (wet, dry or silage), compared to corn-urea or corn-soybean-based diets. It is beneficial. Among the growing ewes, the dehydrated the feed contained in the straw/concentrated feed at a dietary level of 10% or 20% resulted in improved animal performance. Daily weight gain and feed efficiency increase at a 10% inclusion rate.

  •  pig

Corn gluten feed contains more protein than corn kernels, but its dietary fiber content is also much higher, resulting in lower energy values. For growing pigs, the net energy of the feed is about 60% of corn kernels. In adult sows that are better able to digest dietary fiber, the net energy of the feed is 10% higher than that of growing pigs. Another limitation of the feed in pig nutrition is its low lysine and tryptophan content, combined with standardized ileal amino acid digestibility values, which are 15% lower than corn kernels due to higher dietary fiber content.

  •  rabbit

Corn gluten feed is a typical ingredient in Western European rabbit food, especially in Spain. It is used without any problems, mainly as a source of protein (even if it lacks sulfur amino acids) and as a digestible fiber.

  •  fish

Corn gluten feed has been used as a fishmeal substitute in the diet of fry and sub-adult tilapia. For fry, diets containing 67% corn gluten meal (28% total dietary protein) had better feed efficiency than diets containing 30% gluten feed (32% dietary protein). In an adult diet, the level of diet included can range from 13% to 19%. The feed has been reported to have a high feed efficiency and a cost-effective ration without compromising fish growth.


3、Potential constraints

The addition of sulfur dioxide during the wet milling process can help extract the starch. However, if the sulfur concentration in corn gluten feed is between 0.33 and 0.73%, it may be higher than the safe upper limit for cattle. Feeding large amounts of the feed can cause sulphur poisoning, resulting in reduced feed intake and possibly cattle death. A specific disease associated with excess sulfur is polio softening, which affects the nervous system, leading to blindness, disharmony and seizures. Excessive dietary sulfur also increases the risk of copper deficiency

The feed is not a very good ingredient for poultry because its protein and energy content does not meet the high demands of poultry production. Therefore, the maximum recommended level for broilers is quite low (about 10%), but it is higher for laying hens with lower energy requirements. Up to 20-25% corn gluten feed can be included in balanced diets for laying hens without degrading performance. It may be a good ingredient in the induction of molting procedures.
