Fertility of sows of different genotypes on individual farms in regions suitable for intensive pig production
Plodnost krmača različitih genotipova na individualnim gazdinstvima u regionima pogodnim za intenzivnu proizvodnju svinja
Project: Implementation of various rearing – selection and biotechnological methods in breeding of pigs (MESTD - 31081)
Abstract
On the territory of the Mačva and Braničevo region, reproductive properties for 1902 litters were monitored in 6 pig genotypes: Swedish Landrace (SL), Large White (LW) and crosses - SL x LW, LW x SL, German Landrace (GL) x LW and LW x GL. The following parameters were observed: number of live-born piglets in the litter, number of stillborn piglets in the litter, number of piglets reared per litter, duration of lactation (days), and litter mass at weaning (kg). All sows were reared on medium size and large farms (from 20 to 120 sows). The highest number of live-born piglets was determined for LW genotype (12.39), as well as the highest number of piglets reared per litter (11.32), while the highest number of stillborn piglets was found in sows SL x LW and GL x LW (0.50). The lactation duration was the highest in genotype LW x SL (34 days), while the greatest mass of the litter was determined in sows of the LW genotype - 93.42kg. Observing the region as a factor, it was found that all investigated parameters vary statistically significant (P<0.01), except for the mass of the litter at weaning. The Braničevo region had better results for the following parameters: the number of live-born piglets, the number of stillborn piglets, while the Mačva region showed a higher number of reared piglets, a shorter lactation duration with a higher mass of litter at weaning. By testing of the significance, it has been established that the breed highly statistically significantly (P<0.01) affects all the parameters tested except for the number of live-born piglets.
Sažetak
Na teritoriji mačvanskog i braničevskog regiona praćene su reproduktivne osobine 1902 legla kod šest genotipova svinja: dve čiste rase, Švedski Landras (ŠL), Veliki Jorkšir (VJ), kao i četiri meleza nastala ukrštanejm ŠLxVJ, VJxŠL, Nemačkog Landrasa (NL) xVJ i VJx NL. Praćeni su sledeći parametri: broj živorođene prasadi u leglu, broj mrtvorođene prasadi u leglu, broj odgajene prasadi po leglu, dužina trajanja laktacije (dani) i masa legla na zalučenju (kg). Sve krmače su se nalazile na srednjim i velikim gazdinstvima (od 20 do 120 krmača). Najveći broj živorođene prasadi su imale krmače genotipa VJ (12,39), kao i najveći broj odgajene prasadi po leglu (11,32), dok je najveći broj mrtvorođene prasadi utvrđen kod krmača genotipa ŠLxVJ i NLxVJ (0,50). Dužina laktacije je bila najveća kod genotipa VJ x ŠL (34 dana), dok su najveći masu legla imale krmače genotipa VJ (93,42kg). Posmatrajući region kao faktor, utvrđeno je, da su svi ispitivani parametri statistički značajno (P<0.01) varirali, izuzev mase legla na zalučenju. Braničevski region je imao bolje rezultate za parametre: broj živorođene prasadi, broj mrtvorođene prasadi, dok je mačvanski region imao veći broj odgajene prasadi, kraće trajanje laktacije sa većom masom legla na zalučenju. Testiranjem značajnosti utvrđeno je da je genotip statistički značajno (P<0.01) uticao na sve ispitivane parametre osim na broj živorođene prasadi.
