INDEXES OF BULL’S BLOOD AT THE DIFFERENT RHYTHMS OF THE INTENSIVE PHASE FEEDING
The purpose of researches is to increase intensity of bull’s height at conservation in normal physiological state by use of phase feeding. Scientifically-economic experience, in which Simmental bulls were intensively grown with use of the phase feeding method, based on the periodic change of ration’s food value with 80 to 120% from norm for activation of the biological phenomenon of cattle height indemnification is conducted. It is thus possible to increase the level of the productive use the sapling of voluminous forage. In this case there was a question about the physiological state of animals, which haematological indexes was testified. It was well-proven that feeding of bulls by phase principle does not cause the substantial changes of morphological composition of blood and its biochemical indexes. During experience they were within the limits of physiological norms. It is certain that the most effective is diminishing and increase of bull's rations food value by phase principle on 20% from norm through each 10 days. Thus maintenance of red corpuscles and haemoglobin in blood of bulls increases on 11.3-11.4% and 10.3-14.8% (P>0.95), maintenance of general albumen - on 6.4-7.2%, and albumens - on 4.8-7.8%. It is testified to the increase of tension of the ORP processes in the organism of bulls, that accompanies the increase of intensity cattle height on a 15-16%. Increase of rhythm of the bull's phase feeding from 10 to 15 and 20 days accompanied by the decline of albumens maintenance in their blood on 6.4 and 5.4% in age 13 months, and on 4.8 and 7.8% - in 16 months. Accordingly, value of A/G coefficient was to most in bull’s blood, in feeding of which used phase method with a rhythm 10 days (0.77-0.83).
