Progut® Rumen: Benefits and profitability

In University trials and farm tests the hydrolysed brewery yeast product has shown to improve the milk yield and feed utilisation of dairy cows (table). On average the milk yield has increased by 1.8 kg per cow/d and feed utilisation by 6 %. A large scale farm survey with 22 Finnish dairy farms in 2006-2007 showed that the Progut response was the same in different lactation phases (figure). The trial results are presented more in details in the Chapter "Research and Trials". Calculated with the average improvement in milk yield (1.8 kg/cow/d) and with milk price of 37 cents per litre, the economical benefit of Progut investment was more than € 200 per cow and year (value of milk - feeding costs).
