The role of monensin in feed

Monensin  can increase the ratio of propionic acid and total acid produced by rumen fermentation, and improve the conversion rate of feed; it can inhibit the growth of rumen Gram-positive bacteria; it can affect the concentration of lactic acid and volatile fatty acids to change the rumen pH value, relieve Acidosis; it can also prevent coccidiosis in chickens, lambs, calves, rabbits and other animals.

1. The role of monensin in feed

1. Monensin can increase the ratio of propionic acid and total acid produced by rumen fermentation, inhibit the production of methane, carbon dioxide and other gases, and help improve the conversion rate of feed.

2. Monensin can selectively bind to some specific cations, and then pass through the cell membrane of some rumen microorganisms. By changing the ion transport of the cell membrane, it causes a change in the ion balance inside and outside the membrane, thereby selectively reducing the rumen The number of internal bacteria, such as Gram-positive anaerobic bacteria, including bacteria that produce acetate, butyrate, hydrogen ions, lactate, and formate.

3. Monensin can regulate the rumen microbial flora, inhibit the activity of lactic acid-producing bacteria, ammonia-producing bacteria and gas-producing bacteria, thereby affecting the concentration of lactic acid and volatile fatty acids, changing the pH value of the rumen, and alleviating acidosis.

4. Monensin can reduce the degradation rate of protein in the feed in the rumen and the concentration of ammonia nitrogen in the rumen, promote the synthesis of rumen bacterial protein, and thin the intestinal wall, which is conducive to the penetration and absorption of nutrients.

5. Monensin can affect the ion balance in the worm, causing the worm to rupture and die, and it can also prevent coccidiosis in chickens, lambs, calves, rabbits and other animals.

2. Does the country allow monensin to be added to feed?

1. The country allows monensin to be added to feed.

2. When raising chickens, 900-1100g of 10% monensin sodium premix can be added per 1000kg of feed; when raising beef cattle, each head can be fed with 2-3.6g of 10% monensin sodium premix per day Mixture. Every 1000g of 10% monensin sodium premix contains 100g of monensin.

3. It should be noted that the drug is prohibited for laying hens, lactating cows, and equine animals.
