Introduction Nutritional Supplements
The ban (prohibition) on using antibiotics
Betaine is an amino acid derivative found in shellfish, spinach, cereals, and is extracted from sugar beet (a byproduct of the sugar beet industry), has recently come subject of several works in the world. It can act as osmolyte in vertebrate species and as a methyl donor. Thus partly reducing the requirements for other methyl donors (e.g., methionine, choline). Studies on the dietary betaine effect on performance of poultry and pigs show variable results In some experiments, betaine supplementation improved Average Daily Gain (ADG) and/or carcass quality parameters, whereas in others studies, betaine had no effect
It seems to have a positive impact in the fight against coccidiosis. Betaine acts on one hand by limiting parasite development in the case of E. acervulina, the other hand by maintaining the integrity of intestinal cells because of its action osmoprotectrice. Coccidial infections, mainly those of the small intestine, cause diarrhea and dehydration. Or the fluctuations in cellular hydration significantly affect
Betaine, which is an analogue of choline and a methyl donor, stabilizes cell membranes by interaction with membrane phospholipids during dehydration. By protecting against the osmotic stress associated with dehydration, betaine allows normal metabolic activity of cells. Indeed Betaine protects many types Cellular stress. Everything happens as if Betaine allows to maintain an normal activity Metabolic of intestinal cells, allowing normal growth animals even though the coccidian infection is not stopped
Observations that the dietary betaine effect increases when feed intake is restricted or increases with decreasing dietary energy density suggest that betaine can also affect energy metabolism. In broilers, betaine aids the birds’ response to a coccidia challenge. This indicates that dietary betaine may be beneficial specifically under energy-limiting and/or stressful conditions.
