Effect of Lactobacillus Rhamnosus and Propionibacterium Freudenreichii Inoculated Silage on Nutrient Utilization by Dairy Cows

First cut red clover-grass mixture sward were ensiled in two pits with inoculant (Lactobacillus rhamnosus + Propionibacterium freudenreichii ssp. Shermanii) and without any additives. Fermentation quality, nutrient losses and aerobic stability of silages were determined. The inoculated silage had no butyric acid, nutrient losses were lowered by 19.4%. In inoculated silage organic matter digestibility and energy values were significantly higher compared to the ordinary one. In addition, a feeding study to compare influence of inoculated and non-inoculated silage on milk yield, yield of energy corrected milk (ECM), milk fat and milk protein was conducted. Ten lactating dairy cows were divided randomly into 2 groups each of 5 cows. First group of cows were fed inoculated silage (experimental) and second group was on non-inoculated silage (control). The lactating dairy cows in experimental group consumed on average 0.89 kgDM more compared to controls. Further, inoculated silage fed cows tended to increase the milk yield and ECM was by 2.1 kgday cow higher compared to non-inoculated silage fed cows. In cows on inoculated silage the output of milk fat and milk protein was by 84.8 and by 58.6 g daycow higher compared to cows on non-inoculated silage (P<0.05).
