What are the nutritional properties of cake feed?

Cake meal as feed includes: soybean cake (meal), peanut cake (meal), cottonseed cake (meal), rapeseed cake (meal), sunflower seed cake (meal), sesame cake and so on. The main nutrients are listed below.

1) Soybean cake (meal). Soybean cake (meal) is the residue of soybean oil extraction after being pressed into tablets and leached with solvent. It contains 45% refined protein, 1% crude fat, nitrogen-free extract, crude fiber, and 6% crude ash; Soybean cake is the residue of soybeans after they have been mechanically pressed to extract oil.

It contains crude protein, crude fat 4%, nitrogen-free extract, crude fiber, and crude ash.

2) Peanut cake (meal). Peanut cake (meal) is the residue of peanut after hulling, non-hulling, pressing or solvent leaching to extract oil.

Non-hulled peanut cake, crude fiber contains mHigh (, other nutrients contain the lowest relatively low.)

3) Cottonseed cake (meal). Cottonseed cake (meal) is the residue of cottonseed after hulling, delinquencing and oiling. Cottonseed meal contains the most nutrients:

Crude protein 36%, crude fat 1%, crude fiber, crude ash 6%. High-quality cottonseed cake (meal) has less free gossypol (below), more protein and lysine content, and high nutritional value of feed.

4) Rapeseed cake (meal). Rapeseed cake (meal) is the residue of rapeseed oil extraction. The average nutrient content of rapeseed cypress is: crude protein 35%, crude )!1% of line fat, 11% of crude fiber, and 11% of crude ash.

5) Sunflower seed cake (meal). Sunflower seed cake (meal) is the residue of sunflower seeds after oil has been extracted. The nutrient content of sunflower seed cake after hulling and oil extraction is generally as follows:

Crude protein crude fat 7%, crude fiber 13%, nitrogen-free extract, crude ash; The nutrient content of hulled sunflower seeds (meal) is generally as follows: crude protein, crude fat 4%, crude fiber, nitrogen-free extract, and crude ash. The crude fibre content of non-hulled sunflower cake (meal) was high (24% and 34% respectively), while the content of other components was relatively low.

6) Sesame cake. Sesame cake is the aftermath of sesame seeds after oil has been pressed. Its nutrient content is generally as follows:

Crude protein 48%, crude refers to fat 3%-4%, crude fiber 2%-3%, nitrogen-free extract 30%-35%, crude ash 9%. Sesame cake is a good source of protein feed for fish, which can be fed directly or used as a compound feed raw material.

Hello dear, what are the common anti-nutritional factors of cake feed? A: Legumes, soybeans, peas, chickpeas, broad beans, etc. are good protein raw materials, they all contain anti-nutritional factors, limiting the amount of addition in animal feed.

These anti-nutritional factors include protease inhibitors, phytolectins, urease, lipoxidase, cyanogenic glycosides, and antivitamin factors. By intensifying heat, these anti-nutritional factors can be destroyed, so raw soybean meal cannot be fed to livestock and poultry.

Soybean meal is one of the most widely used among all types of oil meal. The demand for soybean meal is mainly concentrated in the feeding industry and feed processing industry, which is used to produce livestock and poultry food feed.

About 85% of soybean meal is used for poultry and pig feeding. Soybean meal is rich in a variety of amino acids, which are very beneficial for poultry and pig intake. Experiments have shown that the amino acids contained in soybean meal alone are sufficient to balance the diets of poultry and pigs without the addition of animal protein, thereby promoting nutrient absorption.

Fermented soybean meal has a wider range of uses, not only suckling pig feed is available, livestock and poultry of other ages can also be used, aquatic feed can replace 50% of fishmeal, low cost, good effect, is a practical technology that can be promoted in a large area.

In pig feeding, soybean meal is the main protein feed for pigs, and animal protein is sometimes added as an additional protein additive, but in general, soybean meal is used to the maximum. If the pigs are fed, they are fed with animal protein feed and vitamins such as fishmeal, which is very beneficial to the growth of the pigs.

In dairy cows, delicious and easily digestible soybean meal increases milk production. Soybean meal is also one of the most important oilseed meals in the breeding of beef cattle. However, in the process of cattle feeding, sometimes there is no need for high-quality soybean meal, and the same feeding effect can be achieved with other meals, and because ruminants can use non-protein nitrogen such as urea, they can consider feeding less or not feeding soybean meal to help reduce feed costs.

In the feeding of chickens, soybean meal is also an excellent protein feed for laying hens. If soybean meal resources are sufficient, animal protein feed (such as fishmeal) can be fed less, or even no feed, so as to reduce feed costs. However, chicks and breeders should also be fed an appropriate amount of fishmeal.

The feed with the highest lysine content in the cake was the pararot () leakage.

a.Soybean cake meal.

b.Canola cake meal.

c.Cottonseed cake meal.

d.Peanut cake meal.

Correct answer: Soybean cake meal.

Soybean cake and meal refer to oil cake and meal made from soybeans, which are different from those made from black soybeans. Soybean cake and meal are the best cakes and meals among all cakes and meals, and are widely used by countries all over the world. The metabolic energy of soybean cake (for chickens) is high, up to megajoules per kilogram.

In the feed of cake and meal, it is only slightly lower than that of peanut cake and meal (shelling). The metabolic energy of soybean meal can reach more than megajoules per kilogram when the soybean skin is removed.

Soybean cake and meal are commonly used in the preparation of high-energy diets for fast-growing meat animals. At the same time, soybean cake and meal have good palatability, and all kinds of animals love to eat them, and even carnivores, such as mink, shrimp, fish, cats, dogs, etc. The protein content of soybean cake and meal is between 40% and 44%, and the protein content is higher.

The composition of essential amino acids is also quite good, especially the lysine content, which is the highest content in cake and meal feed, which can be as high as or even up to, which is 1 times that of cottonnut cake, rapeseed cake and even peanut cake, so it is suitable for the needs of fast-growing animals. The ratio between lysine and arginine in soybean cake and meal is also appropriate, about 100 130, which is very important for pigs and chickens.

Compatible with a large amount of corn and a small amount of fishmeal, it is especially suitable for the amino acid nutritional needs of poultry. The disadvantage of soybean cake and meal in amino acid content is that the methionine content is insufficient, which is slightly inferior to rapeseed cake, meal and sunflower kernel cake and meal, and slightly higher than cotton nut cake, meal and peanut cake and meal. Due to the high lysine content of soybean cake and meal, measured by the appropriate ratio of lysine and methionine, it is even more felt that methionine is insufficient.

Therefore, in the diet that mainly uses soybean cake and meal, DL-methionine is generally added to meet the nutritional needs of animals.

Another characteristic of soybean cake and meal is that the content of isoleucine is high, which is the most in cake and meal feed, and it is also the best one in terms of the ratio with leucine.

The content of tryptophan (and threonine) in soybean cake and meal is also particularly high, so it is compatible with corn to make up for the shortcomings of corn. In addition, the calcium and phosphorus content, trace element content and vitamin content of soybean cake and meal are also characteristic, and the selenium content of soybean cake and meal is low, and the soybean cake and meal produced in the selenium-deficient areas in the northeast of the country should be monitored. Regarding the content of vitamin E, it contains more residual oil, and the content of vitamin E is higher after storage.

The vitamin E content of other cakes and meal feeds is also subject to this limitation.
