How to process and prepare ruminant diet.

According to the different needs of ruminants, different feeds are prepared. During preparation, feed raw materials are crushed, fully mixed in a blender according to the nutritional needs of ruminants, and extruded into granular shapes by granular feed machine. Granular feed has comprehensive nutrition and can be directly fed to cattle and sheep. Granular feed is usually cylindrical. The diameter of cattle pellet feed is 4 ~ 5 mm, and the length is 10 ~ 15 mm, and the diameter of sheep pellet feed is 2 ~ 3 mm, and the length is 8 ~ 10 mm ... During processing, the loss of nutrients should be minimized.

Total Mixed Diet (TMR) is a kind of "full-price" diet provided for dairy cows according to their nutritional needs and feeding strategies at different growth and lactation stages, and according to the formula provided by nutrition experts, for dairy cows to eat freely. The traditional feeding procedure of dairy cows is: silage-concentrate supplement (mixed with water)-auxiliary materials (residue)-green feed-hay-drinking water, etc. Cows tend to be picky eaters, which leads to unbalanced nutrient intake and waste of feed. TMR can increase the dry matter intake of dairy cows, and alleviate the negative nutritional balance between energy demand and eating for high milk yield in early lactation. Can simplify the feeding procedure, facilitate the mechanization and automation of feeding, and adapt to the large-scale, professional and scattered feeding mode of dairy production; Mix the concentrate and coarse ingredients evenly to improve the palatability of the feed and avoid the phenomenon of picky eaters and unbalanced nutrition in dairy cows; It varies from cow to cow, so the feeding management is more targeted and it is easy to control the nutritional level of diet; Enhance rumen function, maintain the stability of rumen pH value, and reduce the incidence of dairy cows; Non-protein nitrogen-containing substances such as urea and ammonia can be used more effectively.
