The objective of this review is approach the use sources of degradable protein and non degradable in rumen, thus like the nitrogen compounds non-proteinaceous, in ruminants nutrition. The animal nutrition proves as target of large studies because your fundamental contribution in animal production, besides being the biggest fact more costly inside the productive system. In nutrition the protein has a key role in meet metabolic demands of the animals, making your development and production of agree the physiological limits. However an important fact the nutrients are crosslinked, then don't just the protein, but the carbohydrates and energy sources should be considered too, for a effective utilization by animals. The ruminants, specifically, are anatomically adapted for utilization of nitrogen compounds non-proteinaceous source, this characteristic favors the use of foods more affordable relative to the real protein foods. However, the inclusion this source in feeding should be performed according the production system situation, ensuring a better nutritional support, and consequently superior animal performance. Knowledge about the importance and function of rumen degradable protein and rumen undegradable protein is essential for their use in ruminant diets, which may reduce the cost of feed, and the excretion of nitrogen in the environment. Through knowledge of fractions that compose the protein and their degradation rates can be formulated diets in order to maximize the degradation synchronism of carbohydrates and protein and thus promote increased efficiency of microbial synthesis. |
