TEST ON A COMMERCIAL FARM IN SCOTLAND
The effect of pHix-up on milk production and quality was tested on a dairy farm in Scotland, comparing the production of 240 dairy cows divided into 2 groups, with and without pHix-up. The cows were fed a Total Mixed Ration (TMR) consisting of 51% concentrate, containing 19% starch and 36% DM* of NDF**.
The first group had no buffer in their diet, producing an average of 38.8 kg of milk.
The second group received 100g/cow/day of pHix-up, while the rest of the ration remained unchanged.

pHix-up vs feeding without buffer
The supplementation of pHix-up in the diet stabilized the ruminal pH, as shown by the 72% decrease in time spent with ruminal pH below 5.8, improving the intraruminal parameters of the microflora.
Regarding milk production, the supplemented group had an average increase of 1.1kg of milk, with 30g extra fat content and total protein.
