In spring dairy cows are often gradually transitioned from a silage- and concentrate-based ration (total mixed ration, TMR) to pasture. Rumen microbiota adaptability is a key feature of ruminant survival strategy. However, only little is known on the temporal and spatial microbial alterations involved. This study aims to investigate how the rumen liquid (LAAB), particle (PAAB), and epithelium (...

BACKGROUND Frequent use of antibiotics to stimulate growth and health of animals leads to the development of antibiotic-resistant populations of microorganisms. In this context, alternatives like herbs and spices to antibiotics are of importance, as they are natural products. Therefore, the present experiment was designed to evaluate the performance, carcass traits, hematology and serum biochem...

This aim of this study demonstrated the relationship between nutritional variables ration and fertility parameters in postpartum period dairy cattle farms. All farms, which used present study, were with problems (calving range ≥14 months artificial insemination number ≥1.8). Ration milk samples taken from selected Fertility records herd registration systems examined. In urea nitrogen (MUN) leve...
