Abstract:Cilj raziskave je bil analizirati stanje plodnostnih parametrov in lastnosti plodnosti, ki vplivajo na učinkovitost reje prašičev. V raziskavo smo vključili dva hleva, hlev A (43 plemenskih svinj) in hlev B (6 plemenskih svinj). V raziskavi smo ugotavljali vpliv trajanja laktacije na uspešnost pripustov, vzrok za majhno število gnezd/svinjo/leto, dvig oziroma padec števila živorojenih, mrtvorojenih in odstavljenih pujskov glede na laktacijo plemenske svinje in naredili primerjavo ekološke reje s konvencionalnim raziskovalnim hlevom. Vpliv dolžine laktacije, brejosti, zaporedne laktacije in načina reje na preučevane lastnosti smo izračunali z analizo variance. Razlike med obravnavanji pa smo preverili z Duncanovim testom pri 95 % tveganju. Nato smo izračunali tudi povezanost (korelacijski koeficient, r) med različnimi lastnostmi. Ugotovili smo, da pride pri dlje trajajoči laktaciji hitreje do estrusa in uspešnega pripusta, da so pregonitve posledica za vzrok manjšega števila gnezd/leto, da se z zaporedno prasitvijo poporodni premor skrajša za 14 dni ter da se število živorojenih in mrtvorojenih z zaporedno laktacijo poveča. Podatki, na katerih smo ugotavljali lastnosti plodnosti, ki vplivajo na učinkovitost reje, so precej nižji od ciljev slovenske prašičereje.

Title:Reproduction characteristies and their effects on breeding efficiency of sows
Abstract:The goal of the research was to analyse the state of fertility parameters and fertility properties that affect the efficiency of pig breeding. The research includes two stables, stable A (43 sows) and stable B (6 sows). The study tests the effect of the duration of lactation on the performance of mating, the reason of small number of nests/sow/year, the increase or decrease in the number of live births, stillbirth and weaned piglets with regard to the sow’s lactation. A comparison of ecologic breeding with the conventional research stable was also carried out. The influence of the length of lactation, gestation, successive lactation and the type of breeding on the studied properties was calculated by analysis of variance. Differences between treatments were checked with the Duncan test at 95 % risk. We than calculated the correlation (correlation coefficient, r) between different properties. It was found that longer lactation results in faster oestrus and a successful mating, that returning is the reason for smaller number of nests/year, that with successive farrowing the after-birth break is shortened by 14 days and that the number of live births and stillbirths increases with successive lactation. The data on which the properties of fertility which affect the efficiency of breeding were determined are much lower than the goals of Slovenian pig breeding.
Keywords:sows, fertility, sequence lactation, numbers of pigs/nest
