Productivity of dairy cows and quality of milk-raw material with different cosmophysic activity

Abstract


The results of studies 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 raw milk) are presented. It was found that during the phase of growth of the activity of the Sun and the increase in the values of the Wolf index (sunspot) in the first half of the 24-year eleven-year cycle of solar activity, the average value of Wolf (sunspot) numbers varied from 0 to 100. For 2-3 years, at the lower peak of solar activity, and 2-3 years - at the top peak of activity, minimal and unreliable correlation relationships were observed. The most stable connections occur in the middle of an upswing or a decrease in solar activity. An increase in the relationship between the studied indicators was observed when the animals achieved maximum productivity. With an increase in milk yield from 7500 kg to 8500 kg, and further to 10,000 kg, the correlation coefficient was + 0.37, + 0.52 and + 0.64, respectively. The maximum influence of solar activity Wolf (sunspot) numbers) on the average productivity of one animal in the household is manifested at the peak of solar activity growth. It has been established that during the years of the rise of solar activity with low absolute values of Wolf (sunspot) numbers, low yields are more likely, and in high solar activity years, higher dairy values (record) are more likely. It was noted that all the components of milk decreased on days of increasing solar activity. The correlation coefficients for protein and milk fat content with Wolf (sunspot) numbers were r = -0.34 and r = -0.22, P ≥ 0.95. Correlation analysis revealed a reliable correlation of bacterial contamination and the number of somatic cells r = +0.28 and r = +0.31 (at P ≥ 0.95), respectively, with the Wolf (sunspot) numbers. In the collection milk, the negative correlation by fat content r = -0.12, density r = -0.18, acidity r = -0.17, protein content r = -0.19, sugar content r = -0.14, minerals r = -0.17 was observed with an increase in solar activity.
