What is the function of monensin?

What is the function of monensin?

Monensin is an ionophoric antibiotic used to treat bacterial, fungal, and parasitic infections. This pharmacological agent attenuates Wnt signaling, causing lower nuclear and cytoplasmic β-catenin as well as a significant decrease in the transcription of Wnt target genes.

What is the mechanism of action of monensin?

Mechanism of action Monensin A is able to transport these cations across lipid membranes of cells in an electroneutral (i.e. non-depolarizing) exchange, playing an important role as an Na+/H+ antiporter.

Can chickens eat monensin?

Broiler Chickens: Feed continuously as the only ration. May be fed up to point of laying….Directions for Use.

What is the withdrawal time for monensin?

Withdrawal of monensin from the feed for 5 or 7 days produced higher feed consumption and weight gain values compared with those of unmedicated broilers. Increasing the withdrawal period to 10 days did not produce greater growth improvement.

How does monensin modulate the fermentative metabolism in the rumen?

Monensin is a carboxylic polyether ionophore fed to ruminants to modify rumen fermentation dynamics by selectively inhibiting growth of gram-positive bacteria, which produce most of the acetate, lactate, and hydrogen in the rumen [3,4].

Is monensin an antibiotic?

Monensin was the first ionophoric antibiotic approved for use by the Food and Drug Administration (FDA) in the USA. Monensin A is an antibiotic which is used as coccidiostat and growth promoting agent in veterinary practice.

How does monensin work in cattle?

Monensin is an ionophore that increases overall energy yield from feed, and improves animal performance. It does this by reducing gram-positive bacteria that favour fibre fermentation in the rumen, thereby increasing gram-negative bacteria that favour starch fermentation, and altering the volatile fatty-acid profile.

Is monensin the same as rumensin?

In the US, monensin (trade name “Rumensin”- manufactured by Elanco Animal Health) is a feed additive for cattle indicated “for improved feed efficiency, for increased rate of weight gain, and for the prevention and control of coccidiosis caused by Eimeria bovis and Eimeria zuernii”.

What is monensin sodium?

An antiprotozoal agent produced by Streptomyces cinnamonensis. It exerts its effect during the development of first-generation trophozoites into first-generation schizonts within the intestinal epithelial cells.

What does dexamethasone treat in cattle?

Dexamethasone is a potent therapeutic for treatment of the fatty liver syndrome or primary ketosis in post partum dairy cows.

What is monensin used for in cattle?

Monensin is a feed additive produced by a strain of Streptomyces cinnamonensis that has been used to improve milk production and feed efficiency by a mechanism linked to rumen fermentation of lactating dairy cows.

Can rumensin be fed to pregnant cows?

The cows receiving 200 mg of Rumensin per head daily had a 97% pregnancy rate or 6 extra calves per one hundred cows in the herd. Looking at the Kansas State University and the Elanco studies together, an amazing effect of Rumensin for the beef cow can be seen.
