Abstract :

Introduction[1] Corn grain represents the most important energy source in ruminant diets. In high-producing dairy cows, the diets contain high levels of corn in order to meet their energy requirements. Corn has a complex structure where a range of nutrients interact with each other or physically associations. Ultimately, the quantity and availability of these nutrients determines the nutrition ...

Abstract :

Introduction[1] Forages are grown mainly for feeding livestock, especially in dairy cows, because adequate roughage is needed in diets to provide good rumen function. However, as more roughage is fed, the energy density of the diet is reduced. So, the production of high quality forage is very important for dairy producers. High quality forage has direct effects on animal production efficiency, ...

AGROVOC Terms :

molasses; fattening performance; slow release urea; digestibility; rumen fermentation

Abstract :

Introduction One of the limitations of conventional urea usage in ruminant diet is rapid hydrolysis and increase in ruminal ammonia concentration and its lack of synchrony with carbohydrate degradation and microbial growth in the rumen. An alternative strategy is continuous supply of nitrogen using slow release urea (SRU) and gradual release of ammonia in the rumen. Sugar-containing liquid fee ...
