Efficiency and quality of livestock production at different space activity. Part 1

It is established, that a gain of heifers and fowl, a milk yield of cows, a chemical compound of milk, an egg production of hens, safety of young animals of large horned stock, fertilization of cows and heifers correlated with parameters of space activity. On the average value of a correlation coeff...

Summary:It is established, that a gain of heifers and fowl, a milk yield of cows, a chemical compound of milk, an egg production of hens, safety of young animals of large horned stock, fertilization of cows and heifers correlated with parameters of space activity. On the average value of a correlation coefficient makes on mass 0,24, on a milk yield 0,26, on fat 0,19, on fiber 0,18. The opportunity of the forecast of changes of efficiency of animals concerning the predicted space activity is shown.
