The transition period of a cow is characterized by marked changes in metabolism as the cow prepares for parturition and lactogenesis. Aim of the present study was the evaluation of the effect of feeding dairy cows with malt extracts on milk production. Ten days before calving, 22 multiparous Holstein dairy cows were divided in two groups and received for four months the same base diet added with an experimental concentrate (1.5 kg/cow/day) containing either corn starch and malt extracts (ME) or only corn starch (CS) as the main energy source. Dry matter intake was not influenced by treatment and averaged 21.7 kg of DM/cow/day. The use of malt extracts determined a numerical increase of milk yield (+0.7 kg/cow/day, i.e. +2.5%) but this difference did not reach the significance level.

Abstract

The transition period of a cow is characterized by marked changes in metabolism as the cow prepares for parturition and lactogenesis. Aim of the present study was the evaluation of the effect of feeding dairy cows with malt extracts on milk production. Ten days before calving, 22 multiparous Holstein dairy cows were divided in two groups and received for four months the same base diet added with an experimental concentrate (1.5 kg/cow/day) containing either corn starch and malt extracts (ME) or only corn starch (CS) as the main energy source. Dry matter intake was not influenced by treatment and averaged 21.7 kg of DM/cow/day. The use of malt extracts determined a numerical increase of milk yield (+0.7 kg/cow/day, i.e. +2.5%) but this difference did not reach the significance level. Milk quality parameters were not influenced by treatment. Further studies will be needed to assess if feeding diets rich in very high fermentable carbohydrates to transition dairy cows can be a valuable strategy
