Serhii Kramarenko Oleksandr Kramarenko Serhii Luhovyi A. Lykhach V. Lykhach

The Large White (LW) pig population used for the present study is from a pig farm managed by 'Tavriys'ki Svyni' Ltd (Kherson region, Ukraine). Three principal components (PC) accounted for near 80% of the dependency structure existing among the eight reproductive traits in the LW sows. TNB in the LW sows increased to the 5th parity and then decreased. The number of weaned piglets was the highest in sows farrowed in June-September, and the lowest in sows farrowed in winter
