Relationship of protein parameters of blood with the indicator of sperm quality in breeding boars

An assessment of the quality of sperm of sperm boars of different breeds and age, as well as correlations between its parameters and the concentration of protein metabolites is given. We used boars-producers belonging to LLC "Agrofirma Ariant". Taking into account the breed, three groups were formed: Group I - dyurks (n = 102), II-nd - Yorkshires (n = 28) and III-I - Landrace (n = 34), which are divided according to the age principle. three subgroups: the first subgroup - boars up to 1 year (10-12 months), the second subgroup - from 1 to 3 years, the third subgroup - 3 years and older. It was found that as boars grow older, the amount of total protein in the blood increases by 5.62-8.62 % due to an increase in the level of globulins (10.48-16.15 %, P
