TEST IN A COMMERCIAL FARM IN ITALY
The effect of pHix-up on milk production and quality was tested on a dairy farm in Italy, comparing the production of 285 dairy cows divided into two groups. The cows were fed a Total Mixed Ration (TMR) composed of 43% concentrates, containing 30% starch and 30% DM* of NDF**.
The first group received a buffer solution of 300g/cow/day of sodium bicarbonate, producing on average 37.3kg of 4% fat corrected milk (4% FCM***).
The second group received 125g/cow/day of pHix-up, while the rest of the ration remained unchanged.

The addition of pHix-up to the diet stabilized the ruminal pH, decreasing the time spent with a ruminal pH below 5.8 by 60%, resulting in the improvement of the intraruminal microflora parameters.
Regarding milk production, the supplemented group showed an average increase of 2.8kg 4%FCM, as well as an additional 100g of total fat and protein.
