Impact on ruminant performance of feed additives

Abstract

In order to elicit the desired reaction at animals, feed additives must be included in high concentrations in the diet. Microorganism-based feed additives for ruminants have been more popular over the last two decades, and this trend is expected to continue. Dairy farmers may utilize feed additives to enhance the nutritional content of their dairy cows' meals and boost revenues by using them properly. The use of supplements should not be seen as a substitute for well-balanced diets and sound feeding procedures, but rather as an addition to them. Although yeast biomass, a byproduct of the alcoholic beverage industry, has previously been employed as a protein source, research into feeding yeast as a probiotic began in the 1950s. Probiotics like yeast were only employed as a feed additive at a lesser level. It was in the 1940s and 1950s when Saccharomyces cerevisiae (Sc) was first used as a probiotic in tiny doses added to animal feed. Anaerobic cellulitis bacteria count and ruminal PH value may be improved by adding yeast to ruminant diets, according to research. mineral absorption is influenced by the patterns of volatile fatty acids.
