Betaine dairy cows
Betaine (trimethylglycine) has numerous functions that may decrease the effect of heat stress (HS) in lactating dairy cows and increase milk production. For example, betaine (Bet) is an osmolyte and a methyl donor.
Ensure diets contain >20% ADF and 30% NDF. balance the amount of non-fibre carbohydrates. levels of NFC exceeding 42% in the diet predispose cows to acidosis. provide effective fibre.
Acidosis is a metabolic disease that occurs when rumen pH levels fall below normal. It usually occurs when cows are not properly transitioned onto high sugar/starch feeds (commonly brassicas or fodder beet) or when large quantities of high sugar/starch feeds are included in the diet.
Benefits of betaine
Betaine other functions are to act as a molecular chaperone, reduce the sensitivity of the microbiota to stress, have antibacterial effects against certain bacteria such as salmonella typhimurium, and be used as a nutrient.
During extreme heat events, milk production may be reduced by 10-15% to 50%.experiments with cows in the thermoneutral zone for 1 week and then in heat stress conditions for 2 weeks showed that milk production decreased from 32 to 27 kg/day and 23 kg during the 1st and 2nd week of heat stress /day (P<0,001;) Dry matter intake (DMI) decreased from 25.5 kg/d to 20.2 and 18.8 kg/d (P<0,001) during weeks 1 and 2 of heat stress.both milk fat and protein percentages and yields decreased after 2 weeks of heat stress. Heat stress increased rectal temperature and respiratory rate (p><0,001).
Betaine increases ADF and NDF digestibility and total nutrient digestibility by increasing the activity of rumen fiber-degrading bacteria and by increasing cell proliferation within the intestinal tissue, increasing the surface availability of absorbed nutrients and improving feed utilization efficiency.
Betaine shows positive effects during heat stress.rectal temperature in cows and sheep decreased with increasing betaine dose.betaine also increased plasma cortisol, glutathione peroxidase, superoxide dismutase, and malondialdehyde levels, resulting in improved antioxidant status when supplemented to dairy cow diets.
Betaine has positive effects on rumen health and fermentation, and can improve yield and performance in dairy cows and goats.In addition to the positive effects on the rumen, there is evidence that betaine has a positive post-rumen effect, with benefits for fertility, production and health in dairy cows and goats under heat stress and thermoneutral conditions.
