AB  - It was demonstrated that boar sperm production and characteristics significantly decrease in the wormer period of the year. As a result, the boars reproductive exploitation efficiency decrease in the wormer season. Therefore, the aim of the present paper was to investigate the influence of cold and warm season on the boars semen quality, in the our intensive pig production conditions. The obtained results clearly show that the main semen quality parameters were significantly (p lt 0.05 or p lt 0.01) higher in the cold, compared with the warm season (ejaculate volume=274ml, sperm concentration=229'106/ml, total sperm number=60'109, progressive motility=79%, and good ejaculates=96%, vs. 218ml, 208'106/ml, 45'109, 69% and 78%, resp.). In conclusion, keeping boars cool during summer and frequent observation of boars to determine if they are being heat- stressed, can significant reduce the negative influence of elevated ambient temperature on sperm production and, consequently, improve boars reproductive exploitation efficiency.
AB  - Ustanovljeno je da su produkcija i osobine sperme nerasta značajno niže tokom toplijeg perioda godine. Posledično, u ovom periodu godine značajno se smanjuje efikasnost reproduktivnog iskorištavanja nerastova. Zbog toga je cilj ovog rada bio da se ustanovi uticaj hladne i tople godišnje sezone na parametre kvaliteta sperme u našim uslovima intenzivne proizvodnje svinja. Dobijeni rezultati jasno pokazuju da su osnovni parametri kvaliteta ejakulata značajno veći (p lt 0.05 or p lt 0.01) u hladnoj, nego u toploj godišnjoj sezoni (volumen ejakulata=274ml, koncentracija spermatozoida=229'106/ml, ukupan broj spermatozoida=60'109, progresivna pokretljivost=79% i dobrih ejakulata=96%, prema 218ml, 208'106/ml, 45'109, 69% i 78%). Zaključak je da rashlađivanje nerastova tokom leta i češća observacija prisustva toplotnog stresa, može značajno smanjiti negativan uticaj povišene ambijentalne temperature na produkciju sperme i, posledično, povećati efikasnost reproduktivnog iskorištavanja nerastova.

AB  - The aim of this study was to investigate: (a) seminal plasma protein content in the Landrace (n = 38), Large White. (n = 44) and Duroc (n = 24) boars breed, as well as boars distribution according to protein content in seminal plasma, and (b) the sperm motility in the semen samples, forming from the ejaculates with high or low protein content, stored in vitro on 17 degrees C for 3 days. Not significant (p > 0.05) differences was found in seminal plasma protein content between three boar breeds. Only 31% of the 106 investigated boars had >= 3.6% protein in seminal plasma. Progressive motility was significantly higher (p  lt  0.01) in the ejaculates with high, compared to the ejaculates with low protein content (82% vs. 76%). After 3 days of storage, in the 1:4 dilution proportion, the average progressive motility was significantly (p  lt  0.01) decreased in relation to this value in native semen from the boars with high (82% to 64%), as well from the boars with low protein content in seminal plasma (76% to 48%). However, the average diluted semen progressive motility was significantly greater (p  lt  0.01) in the boars with high (64%), compared to the boars with low protein content in seminal plasma (48%). The number of good diluted semen samples (>= 65% progressive motility), was also significantly (p  lt  0.01) greater in the boars with high (41%), compared to the boars with low protein content in seminal plasma (12%).

AB  - The aim of the present study was to investigate the possibility of increasing boar's reproductive exploitation by using AI doses of doubly reduced volume and sperm count in the intrauterine AI procedure. The experiment was conducted at a commercial pig farm in Serbia in 2014. Classic intracervical insemination (ICI) was performed by using 50 mL or 100 mL volume doses containing 4 x 10(9) or 2 x 10(9) progressively motile spermatozoa. The same volumes and sperm numbers per dose were used with intrauterine insemination (IUI). Each dose combination was used to inseminate 30 sows. Intrauterine insemination with AI doses of reduced volume (50 mL) and sperm count (2 x 10(9)) did not produce a statistically significant difference (P  lt  0.05) in the farrowing rate (76.7%) as compared with 4 x 10(9) spermatozoa in the same volume (83.3%) or with insemination by doses of 100 mL with a 2 x 10(9) (83.3%) or a 4 x 10(9) sperm count (86.7%). The number of live-born piglets (10.82) was larger following IUI using a 50 mL volume dose with a 2 x 10(9) sperm count as compared with ICI with the same AI dose volume and sperm count (9.85). The results show that the use of reduced AI dosages provides an opportunity for the swine industry to considerably exploit the reproductive potential of genetically superior boars.

AB  - Recently, it was frequently demonstrated that fertility of sows after artificially inseminated is lower than after mating.
