NEW TREND IN RESEARCH ON THE STUDY OF PRODUCTIVE OF ANIMALS IN CONNECTION WITH VARIOUS COSMOPHYSICAL ACTIVITY

Cover Page

Abstract


Brief results of research at the Department of Zootechnics of the PFUR in more than 30 years are reported on the relationship between cosmophysical activity and animal productivity (the rhythm of milk yield of cows and the chemical composition of milk, the biochemical composition of cows' blood). It is established that in even and odd 11-year solar cycles, animals react differently to cosmophysical activity. In even cycles, the increase in solar activity contributes to the growth of milk yields. In odd cycles, increasing solar activity reduces milk yield. The data of scientific observations, covering the periods of even and odd cycles, should be grouped and analyzed separately by cycles. Within 2-3 years, at the lowest peak of solar activity, and 2-3 years - at the top peak of activity (with the change of magnetic poles on the Sun) minimal and unreliable correlations are noted. The strongest correlation was noted in the middle of the rise or decrease in solar activity. The rhythm of milk yield was noted regard-less of the lactation phase of cows. Approximately 1/3 of the time, milk yield increased, 1/3 - decreased and 1/3 - remained at the same level, with fluctuations, with periods from 2.7; 3.3; up to 5.5 days. With an increase in milk yield during 31.0% of lactation days, the content of fat and protein in milk decreased, respectively, 25.8 and 25.4% of the time. With a decrease in milk yield during 33.7% of lactation days, the fat and protein content did not change, respectively, 49.8 and 48.1% days. The most pronounced interval of rhythmicity of the concentration of fat and protein in milk from 2 to 2.5 days with an average value of 2.2 days was established. In addition rhythm 2.8; 3.4; 4.4; 8; 32; 41,1 and 72 days was marked. Approxi-mately with the same cycles in the milk, sugar concentrations, density and acidity were changed.
