Application of high quality vegetable protein feed for beef cattle

Protein feed refers to the feed of crude protein in dry matter and less than 18% of crude fiber. Including animal protein feed (mainly including fish meal, blood meal) and plant protein feed (mainly including beans and various cakes). Firstly, the main types of high-quality vegetable protein feed suitable for feeding beef cattle are introduced for reference by the majority of beef cattle farmers.

First, the beans are: mainly soybeans, peas, broad beans, etc., the common feature is rich in protein content (generally 25%-40% of dry matter quality), good quality, nitrogen-free extracts are lower than the cereals , high digestion energy.

Second, cakes: a by-product of oil extraction. The oil cake used in the pressing method is called the oil cake by the leaching method. The crude protein content is generally from 30% to 45%, and the crude fiber is from 6% to 17%. The minerals contained are generally more phosphorus than calcium, rich in vitamin B and lower in carotene. Chs China Feed Industry Information Network - based on feed, serving animal husbandry

1 Bean cake (粕): Its quality is the best among the cakes, containing more than 40% of crude protein and about 0.9 of beef cattle energy. The best quality of the cake is yellow and fragrant, good palatability, but not more than 20% of the dry matter of the cattle diet.

2 cotton cake (粕): the cotton cake pressed or leached by the sheller contains 32%-40% crude protein, about 10% crude fiber, and the cotton cake with shell contains up to 15%-20% crude fiber. The crude protein is about 20%. Cottonseed cake contains free gossypol toxin, which can cause poisoning after long-term feeding. The calf diet should not exceed 20%. Adult cattle can be fed to the cotton cake without poisoning, but the daily feeding amount should not exceed 2.7kg. It is best to feed the cattle after detoxification.

The detoxification methods of cottonseed cake (粕) mainly include: 1 cooking method: generally after 2-3 hours of cooking, some toxins can be destroyed. 2 Ferrous sulfate method: 1 part of cottonseed cake is soaked with 2.5 parts of 1% aqueous solution of ferrous sulfate for a day and night to be poisoned and then fed to cattle. 3 baking soda method: soak in the tank with 2% baking soda for 24h, remove it and rinse it twice with water, then you can detoxify and feed the cow. 4 Lime water soaking method: soak in 1% lime water for a day and night, soak it and rinse it with water to feed the cow. 5 bentonite method: adding 1% bentonite to cattle diet can effectively prevent gossypol poisoning. 6 Urea or ammonium bicarbonate method: mix with 1% urea or 2% ammonium carbonate, and seal the cattle for feeding after a day and night.

3 peanut cake: peanut cake is a good vegetable protein feed, containing 40%-49% crude protein, metabolizable energy content can exceed soybean cake, is the highest energy level available in cakes, but lysine Insufficient acid and methionine content. Peanut cake has good palatability and aroma. Beef cattle like to eat. It can be used as a feed for yak. ​​However, if the feed is too much, it can cause cattle to diarrhea. Peanut cake is very susceptible to aflatoxin. If the beef cattle eat a lot of peanut cake with Aspergillus flavus, it may cause poisoning. Therefore, peanut cake should be used freshly, not stored for a long time. For peanut cake infected with Aspergillus flavus, it can be fed after detoxification treatment.

4 rapeseed cake (粕): containing about 36% of crude protein, mineral and vitamin content is richer than bean cake, rapeseed cake (粕) contains mustard toxin, preferably after detoxification feeding, if not feeding poisonous rape cake (粕), the average daily feeding amount of cattle is about lkg, and it is best not to feed yak and pregnant cattle. The beef cattle can be fed after being detoxified with 100 ° C hot water. Chs China Feed Industry Information Network - based on feed, serving animal husbandry
