THE INFLUENCE OF CEREAL MILK CREAM IN BREEDINGS ON DAIRY PRODUCTIVITY OF CROPS

The theoretical bases of feed raw fiber influence on milk productivity of cows are revealed. Researches of many scientists have shown that crude fiber increase by 1% in the vegetative mass of any plant reduces its digestibility by 0.5%. The rate of depressive action of crude fiber is expressed by the ratio of the crude fiber content in the feed to its physiological diet requirements. In the middle of flowering phase of alfalfa its green mass has crude fiber content in percentage of dry matter as 32.5%. The cow with a daily milk yield of 40 liters of milk physiologically needs 17% of feed crude fiber. Then the ratio of 32.5% to 17 % is 1.91, which is a measure of depression.
The alfalfa green mass cut in the middle of flowering phase has the highest coefficient of depressive action of crude fiber according to analysis data on the depressive effects of crude fiber in the dry matter of alfalfa at different phases of vegetation. The cows with a daily milk yield of 40 liters of milk have such rate of depression as 1.91. In other words the production of milk on crude protein from 1 kg of this feed dry matter is 1.9 times lower than other dietary rations containing the same amount of crude protein on dry basis matter as alfalfa, but containing 17% of crude fiber as a physiological need. We have got a problematic question. What is the mechanism of such an action? The alfalfa particles with a 32.5% crude fiber content on a dry matter are found in a feed mixture with other feeds in the rumen, where the content of crude fiber is at 17%. The rumen microorganisms are attached to all the feed particles of the feed mixer. However, the concentration of substrates of nutrients, i.e. raw protein is different in the contact zone of microbial digestion. Fodder alfalfa particles containing 32.5% of crude fiber will have a lower concentration of crude protein in the contact zone of microbial fermentation than other feeds similar particles with lower fiber content. The lower concentration of the substrate will cause lower fermentation. The period of all forage mass parts presence in the rumen is the same. Thus, the alfalfa feed particle containing 32.5% of crude fiber and low level of microbial fermentation of raw protein, is fed into the subsequent departments of the gastrointestinal tract.
The depressive effect of alfalfa fiber high level occurs also in the small intestine of the cow when pancreatic enzymes are rather active. Fiber feed generates a significant surface area and "competes" for the possession of surface activity with other chyme components and the intestinal epithelium. This is the main cause of the digestion decrease and nutrients feed consumption in the small intestine with high content of neutral detergent, acid detergent and crude fiber in feed.
