Tannic acid is a specific form of tannin and a type of polyphenol. It is defined in AAFCO as 582.20 for a source of flavour. Quebracho extract is a big complex polymer of tannin (MGM-S), specially for ruminant animals.
MGM-S has been approved to inhibit the growth and activity of methanogenic archaea in the rumen, which are responsible for producing methane as a byproduct of fermentation. It can alter the composition and activity of microbial populations, stimulating saliva production, favouring the growth of bacteria that produce less methane and increasing the proportion of propionate. Therefore, it can prevent the accumulation of lactic acid in the rumen and improve rumen pH stability, working together with marine-sourced calcium carbonate to reduce the risk of rumen acidosis.
MGM-S has been investigated for its ability to reduce the incidence of frothy bloat, which can occur when cattle consume rapidly fermentable feeds, such as high-grain diets in feedlot. MGM can help to reduce the stability of foam in the rumen by binding dietary proteins and maintain a more stable rumen environment, preventing the formation of gas bubbles and reducing the risk of bloat.
MGM-S also shows its anthelmintic effects due to its ability to disrupt the physiology and life cycle of parasites such as nematodes and coccidia.
Freshly milked dairy collected on-farm. Feed supplements like MGM-S are helping improve both milk composition and rumen health in today’s herds.
Adding 70 g MGM-S per day per cow could produce 1.2% more fat and increase milk protein by 3.3%. Adding 0.15% MGM-S to beef cattle diets for 93 days with initial body weight at 180 kg, achieved daily weight gain 180 grams and FCR was improved by 6.72% (8.18 vs. 7.63).
