The content of betaine is high in beet and corn. At present, there are mainly water extraction, alcohol extraction and chemical synthesis. Basically have turn methyl left and right sides, adjust osmotic pressure, lure food action, fight stress action, body fat redistribution and the physiological function such as stable vitamin. It is very important to add betaine to beef cattle feed for beef cattle growth.

Beef cattle are cattle raised for meat production (as distinguished from dairy cattle, used for milk production). The meat of mature or almost mature cattle is mostly known as beef. In beef production there are three main stages: cow-calf operations, backgrounding, and feedlot operations.

For weaned cattle, betaine can improve the growth performance, and 600mg/kg betaine has the best effect.800mg/kg betaine can increase the digestibility of dry matter and crude protein, increase the activity of proteolytic enzyme, increase lean meat rate, decrease diarrhea rate, decrease urea nitrogen and increase serum total iron binding ability.

Similarly, adding betaine can increase daily gain and decrease feed/gain of growing cattle. By improving longissimus dorsi muscle and crude fat content of growing cattle, the beef quality can be improved mainly by increasing redness, decreasing yellowness, cooking loss and shear force, and improving marbling score.

Finally, adding betaine can improve lean meat percentage and muscle fat content of fattening cattle, reduce fat percentage and backfat thickness, and improve carcass quality. The reason for the improvement of intramuscular fatty acid level by betaine may be that betaine promotes fatty acid uptake more than oxidation.
