The key role of protein foods that make treatments less degradable in the rumen but digested in the intestinal tract.

From a conference of the exhibition in Cremona.

Milk production is constantly rising quality standards, as well as increasing the selectivity of the dairy market. That the attention of nutritionists and nutritionists are increasingly devoted to formulating products that enhance the performance of cows milk and higher levels of animal welfare. Featured within this discussion is the theme of food protein to ruminants, with reference to treatments that make food less degradable protein in rumen but digested in the intestinal tract. He's held the conference "Sources of dietary protein bypass feeder cattle milk: benefits, processes and business applications", held last edition of the Fiera di Cremona. Here Matthias buckets, head of the Agrarian University of Bologna, recalled how the protein of microbial origin, namely that produced by rumen bacteria, covers 50-60% of protein needs for the animal, the protein source is more Economic and has an excellent amino acid profile. This protein is part of a pool of proteins postruminali with bypass protein supplied by the diet and a certain amount of endogenous proteins produced by cell turnover.
Nitrogen is the basic element of protein, and is under close observation in the plans for spreading of slurry and as a source of ammonia emission.
The crude protein value that we usually find on labels and in laboratory tests measure the amount of nitrogen, but we will not provide guidance on how the amino nitrogen, as is the non-protein, or to what extent these proteins are degraded at rumen rather than the intestine.

SYNCHRONIZED
The total protein or crude was exploded in the so-called Cornell System in specific localities, depending on the speed of degradation dall'azoto non-protein or NPN, the portion fermentable, soluble protein, insoluble or linked to that.
The modern system of rationing calculate the needs of the animal in terms of RDP or protein in rumen degradable and non-degradable protein or RUP in rumen, which represents the amount of protein that comes from microbial protein.
Moreover, in these programs as Cncps rationing in order to estimate the protein actually used by the cow, was introduced the concept of metabolisable protein, ie the proportion of protein that passes the rumen is digested and absorbed in the form amino acid. Drums then stressed the importance of the issue of synchronization of protein and carbohydrate fermentation in the rumen. To maximize the yield of the ration in terms of microbial protein, it is essential that they arrive simultaneously in the rumen protein and sugar with the same degree of fermentability, so that reactions go hand in hand and the ruminal bacteria have both always available degradation products, protein, carbohydrate and of that: the lack of it leads to either block the synthesis of microbial protein by rumen bacteria which increase in volume and number, creating metabolic disorders more or less important.
Degradable protein, therefore, are important for enhancing the efficiency of rumen fermentation, intended both as a synthesis of microbial protein, and as use of carbohydrates as well as increased fiber digestibility, resulting in a greater availability of energy and a higher amino acid profile Protein available.
