In order to analyze the intensive use of chickens in the conditions of industrial technology, it was postulated to study the characteristics of sperm production and qualitative changes in the sperm parameters of the hams of different directions of productivity and breed in the process of their production use in the conditions of the agricultural private enterprise “Techmet-Yug” of the Vitovsky district of the Mykolaiv region.
In the conditions of the economy, the indicators of sperm production of buds-breeders of large white, Landrace, Pitren and domestic, for fitness for industrial longevity were studied. The productivity was analyzed in the following age periods: from the beginning of use to 12 months of age, 13-18 months, 19-24 months, 25-30 months, 31-36 months. At the same time studied the following indicators: the volume of ejaculate, ml; concentration ml / ml; number of spermodoses, pc.
The volume of ejaculate in the stings of the studied rocks varies with age in different ways. At the age of one and a half these differences are mainly preserved, with the only difference that the numbers go forward with the concentration of the sperm of the breed of the breed of a large white wine, they will stabilize 183 million / ml, in the piebras 108 million / ml (difference of probability P <0.001 ) And the domestic swine is removed from the harsh place, going up to other genus nnam at 29.2 30.7 million / ml (P <0.01 0.001). In 2,0 2,5 years of age, the largest number of sperm in the ejaculate of mallard root lobster (178 million / ml). The largest productive longevity is the Landrace bream, among which only 7% of animals were released during the first two years of life, and in the third year 14.0%. Almost an analogous picture is observed in the large white breed, in which up to three years of age, for various reasons, 23.0% of buds are cleared. And here, amongst the breeds of the breed, Pyrets, the same number (22.8%) is cleared already to two years and another 8.3% in the third year of life. Taking into account the number of sperm dosages obtained from buds up to the age of three, the timing and percentage of their sampling should be confidently recognized that they are most adapted to the intensive industrial technology of rodra rocks.
