IMPLEMENTATION OF ESSENTIAL BIOSTIMULATOR TECHNOLOGY IN SUPPLEMENTARY FEED AS A MIXTURE OF REINFORCING FEED ON HAEMATOLOGICAL AND NUTRIENT PROFILES OF BEEF CATTLE SERUM (CASE STUDY OF BEEF CATTLE FATTENING ON PEOPLE'S LIVESTOCK)

The national meat self-sufficiency program in Indonesia aims to increase the cattle population to meet the country's meat consumption. Beer dregs are a potential alternative feed supplement, as they contain high crude protein and soluble carbohydrates that can affect the rumen microbial population. In addition, essential oil biostimulators derived from citronella are added to the feed as a mixture of reinforcing feed to support cattle health and productivity. This study investigates the effect of essential biostimulators in supplementary feed as a mixture of reinforcing feed on the haematological and nutrient profiles of beef cattle serum, using the case study of beef cattle fattening in People's Livestock. Results showed that the addition of citronella essential oil improved nutrient digestibility and rumen health, and the combination of beer dregs and essential biostimulators positively impacted the haematological and nutrient profiles of beef cattle serum.
