1, the origin of urea feed cattle
Urea is a white crystal, generally containing 42% to 46% nitrogen. After digestion and utilization of bovine stomach, one kilogram of urea is equivalent to 2.6-2.8 kilogram protein feed, but it has not been popularized. By 1922, Ricardoson et al used urea. It has been used as a feed to obtain good results and is widely promoted around the world.
2, the principle of urea feed cattle
Adult cows have developed rumen, with a capacity of 125-187 liters, containing a large number of bacteria and ciliates. Urea enters the rumen and decomposes into carbon dioxide and ammonia to form bacteria proteins, which are broken down into the stomach as the food enters the stomach. Amino acids are absorbed by stomach and intestines.
3, the method of feeding urea
The amount of feed should be appropriate, under normal circumstances, urea to replace 30% of the amount of dietary protein is more appropriate, according to the calculation of concentrates, urea accounted for 2% -3% is appropriate. Urea can not be fed alone, must have crude fiber and energy feed, but can not feed when fasting. The composition of the cow's diet cannot suddenly change, because the rumen microbes change with the nature of the feed and the diet composition suddenly changes.
Microorganisms are difficult to adapt at one time and the feeding effect of urea supplementation is poor. Yak cattle can not use urea supplements for 6 months of age and infirmity.
1.The layout of the functional modules of the equipment is reasonable, the structure is compact, and the appearance is beautiful;
2.Feeding and conveying, pressing, cutting, and discharging are completed in one line, which improves cutting quality and production efficiency, greatly reduces labor costs, and improves working conditions;
3.
The feeding conveyor belt adopts high-quality materials and a reasonable surface anti-skid structure, which is wear-resistant, non-slip, and reliable in positioning; the feeding belt component is a quick-install structure to ensure that the belt is replaced and cleaned quickly and conveniently;
