Abstract
The most important part in reproductive management is the control of boar fertility. A common division of fertility traits is on the: in vitro (sperm traits) and in vivo (return rate, farrowing rate and litter size traits) fertility. In many studies were found differences between breed in the both groups of fertility traits. Variability of sperm traits of boars during the reproductive exploitation is influenced by various genetic (boar, breed) and paragenetic factors/effects (age, season, intensity of use). Good libido is desirable characteristics in boars, but the knowledge of the correlation of libido and boar fertility traits are limited. Also, there is no standardised procedure or methods for the estimation of libido of the boars. The permanent ranking of boars according to the reproductive efficiency should be performing. Good reproductive management implies the timely identification of boars with the low fertility (or close to the average).
