The content of betaine in sugar beet is relatively high. At present, the main methods are water extraction, alcohol extraction and chemical synthesis. It mainly has the physiological functions of about methyl conversion, regulating osmotic pressure, inducing food, anti stress, body fat redistribution and stabilizing vitamins.
Application of betaine in piglets
For weaned piglets, adding betaine can improve growth performance, and adding 600mg/kg betaine has the best effect; 800mg/kg betaine can improve the digestibility of dry matter and crude protein, increase the activity of proteolytic enzyme, increase the lean meat rate of piglets, reduce the diarrhea rate, reduce urea nitrogen and increase the total iron binding capacity of serum.
Application of betaine in growing finishing pigs
Adding betaine can increase the daily gain of growing pigs and reduce the feed to weight ratio; By increasing the content of longissimus dorsi muscle and crude fat of growing pigs, the pork quality can be improved, mainly by increasing the redness, reducing the yellowness, cooking loss and shearing force, and improving the marbling score.
Application of betaine in finishing pigs
The addition of betaine can increase the lean meat percentage and muscle fat content of finishing pigs, reduce the fat percentage and back fat thickness, and improve the carcass quality. The reason is that the improvement of intramuscular fatty acid level by betaine may be due to the stronger role of betaine in promoting fatty acid intake than in promoting fatty acid oxidation.
Application of betaine in breeding pigs
The study on primiparous sows found that betaine could increase the number of weaned piglets at 21 days of age and the weaning litter weight, shorten the estrus interval within 7 days after weaning, and improve the reproductive performance; It can also promote ovulation and oocyte maturation of sows; Because betaine, as a methyl donor, can reduce the level of homocysteine in sow serum by promoting protein synthesis, thus promoting embryonic growth and development and improving sow reproductive performance.
