Importance of synchronization of complex protein / energy in feed for ruminants

Abstract

The objective of this review is to address synchronization between protein and energy, through the study of factors related to dry matter intake, digestibility, microbial efficiency, use of urea protection, minimum and maximum amount of non-protein nitrogen to microbial protein synthesis , nitrogen lost through the urine urea, optimizing the use of non-fiber carbohydrates, the rate of degradation of carbohydrates, food processing and level of concentrate in the diet of ruminants to produce meat and milk. The increase in microbial efficiency to increase the availability of microbial protein to be absorbed in the intestine, supplying, so the production needs of animals. The digestion of ruminants involves constant activity of rumen microorganisms symbiotic with the host, which are highly susceptible to environmental alterations, affecting not only the extent of degradation of food components, but also the quantities and proportions of the products resulting from such action. Knowledge of fractions of protein and carbohydrates is of paramount importance for the synchronization protein / energy in ruminant feed, generating satisfactory performance in animal production efficiency and advances in the formulation of diets, prediction of animal performance and planning and control system production.
