Cattle feeding urea depends on forage grass
Feed urea to cattle, urea can be digested by microorganisms in the rumen of cattle to synthesize bacterial protein, replacing part of protein feed, so urea is a high-quality protein supplement feed for cattle. However, urea is not a protein after all, and its utilization efficiency is affected by many conditions. Generally speaking, urea should be fed to cattle according to the situation of forage grass. Urea can be added in winter and spring when wheat straw, dry corn stalk and hay are the main coarse forage, and it is not suitable to feed in summer and autumn when green forage is the main forage.
The results showed that when the crude protein content in feed was below 11%, the urea utilization rate in rumen was about 70%, and the weight gain effect of cattle was obvious. When the crude protein content in the feed was more than 12%, urea could not increase the weight, but would affect the weight gain or make it lose weight obviously.
In summer and autumn, there are many kinds of wild vegetables, weeds and pastures. Cattle often take green feed as the main one, and green feed contains comprehensive nutrients, especially high crude protein content, generally 12%~ 20%. The digestion and utilization rate of crude protein is also very high, generally reaching more than 70%. At the same time, the quality of crude protein is excellent, and the essential amino acids are comprehensive and the nutritional value is high. Therefore, in feeding wild vegetables, weeds, grass and other green forage mainly when there is no need to feed urea to cattle.

Prevention and treatment of Bovine dampness

Prevention and treatment of vitamin deficiency in pigs in late winter and early spring
Pigs are easy to get vitamin deficiency in late winter and early spring, the main reason is the lack of green feed, coupled with the simple feed of some pig farmers, lack of sunlight and poor air circulation in pig houses, so pigs are easy to get vitamin deficiency in spring. Now the prevention and treatment methods are introduced as follows: vitamin A deficiency. Symptoms: dry skin, dull body hair, indigestion, loss of appetite, slow growth. Some have impaired vision and nervous disorders. Severe spasms, circles, unstable gait, motor disorders, and even hindquarters paralysis can occur. Sow
