At least three quarters of the energy and protein needed for milk production is produced by rumen microbes. Microbes produce volatile fatty acids (VFA), including propionic acid, which is the main energy source for growth and lactation. Progut Rumen has in trials increased the number of microbes in the rumen, which has positively impact milk production. Moreover, the amino acid composition of microbial protein is optimal for milk protein synthesis.
Propionic acid is known to be the main raw material for blood glucose production. Higher levels of blood glucose prevent weight loss and fertility problems during early lactation. Progut Rumen has in trials modified rumen fermentation more towards propionic production instead of methane.
As enhanced microbial activity leads to higher VFA production and less methane, cows have more energy available to produce more milk!
Cows fed using Progut Rumen have in trials increased milk production up to 6 % (Table 1). At the same time feed conversion efficiency has been 5-7 percent higher (Table 2). The effect has been similar with corn silage and grass silage and has been observed throughout the entire lactation period. Rumen fermentation modification by Progut Rumen offers possibilities to achieve higher production level! Better energy status is related to cow health. It has been seen in research cows fed by Progut Rumen are more fit and somatic cell score decreases (Table 2).
