Effect of glycerol supplementation during early lactation on milk yield, milk composition, nutrient digestibility and blood metabolites of dairy buffaloes

What is it about?

The objectives of this study were to investigate the effects of feeding glycerol in early lactating dairy buffaloes on milk production, digestibility, and blood metabolites. The manuscript showed that glycerol, as a glucogenic substrate, induced the increase in blood glucose concentration and higher nutrient digestibility, and resulted to greater milk yield and milk fat percentage. In spite of the higher milk production, the glycerol feeding did not have the adverse effect on energy balance, from the results of no changes in BCS and lower blood concentrations of BHBA and NEFA. Although the effects of feeding glycerol to lactating Holstein cows were reported in some articles, those to lactating buffaloes are new finding data.
