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).
Najvažniji segment u reproduktivnom menadžmentu je kontrola plodnosti nerasta. Uobičajena je podela osobina plodnosti na: in vitro (osobine sperme) i in vivo (procenat povađanja, procenat prašenja i osobine veličine legla) plodnost. Mnoga istraživanja pokazala su razlike između rasa u obe grupe osobina plodnosti. Varijabilnost osobina sperme nerasta tokom iskorišćavanja pod uticajem je različitih genetskih (nerast, rasa) i paragenetskih (starost, sezona, intenzitet korišćenja) faktora. Dobar libido je poželjna karakteristika nerasta, ali saznanja o povezanosti libida i plodnosti nerasta su ograničena. Takođe ne postoji standardizovana procedura ili metod za ocenu libida nerasta. Neophodno je stalno rangiranje nerasta na osnovu reproduktivne efikasnosti. Dobar reproduktivni menadžment podrazumeva pravovremenu identifikaciju nerasta sa niskom plodnošću (ili blizu proseka).
