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 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. This is associated with a reduced fertilization capacity of overdiluted insemination doses. The aim of this study was to investigate 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. 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 the1:4 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%). These results show that seminal plasma proteins play an important role in maintaining the sperm progressive motility of diluted semen in vitro stored for 3 days.

AB  - Work on pig enhancement will continue to deal with improving reproduction characteristics, growth characteristics, feed utilization, trunk and meat quality, and management confidence. On the one hand, adequate methods of quantitative and mollecular genetics will be used, and on the other there will be efforts to increase probability that genetic potential of the animal is exhibited in practical conditions. The objective of this work was to see how and to what extent genetic potential in swine is exhibited in practical conditions. The variability of production characteristics of swine in farms in the Republic of Serbia was examined during a period of 10 years (1991-2000). Reproductive, fattening and trunk quality characteristics varied among farms, genotypes and year of investigation. The average revealed analyzed characteristics in swine are not satisfactory. There is a wide range in the variation of all characteristics among the farms. There are differences between the characteristics of the same swine genotype with regard to the tendency they exhibit per year or farm. Some of them have not shown a clear tendency to increase or reduce, but varied from year to year. The effects of selection and cross-breeding differed considerably.

Prosečna ispoljenost analiziranih osobina svinja je nezadovoljavajuća. Širok je raspon variranja svih osobina svinja između farmi. Razlike postoje između osobina istog genotipa svinja s obzirom na tendenciju koju ispoljavaju po godinama i farmama. Neke od njih nisu ispoljile jasan trend povećanja ili smanjenja već su varirale iz godine u godinu. Efekti selekcije i ukrštanja su veoma različiti.

Koliko je i kako ispoljen genetski potencijal svinja u praktičnim uslovima bio je cilj ovog rada. Varijabilnost proizvodnih osobina svinja na farmama u R. Srbiji ispitivana je u desetogodišnejm periodu (1991-2000. god). Reproduktivne, tovne i osobine kvaliteta trupa svinja variraju između farmi genotipova i godina ispitivanja. Prosečna ispoljenost analiziranih osobina svinja je nezadovoljavajuća. Širok je raspon variranja svih osobina svinja između farmi. Razlike postoje između osobina istog genotipa svinja s obzirom na tendenciju koju ispoljavaju po godinama i farmama. Neke od njih nisu ispoljile jasan trend povećanja ili smanjenja već su varirale iz godine u godinu. Efekti selekcije i ukrštanja su veoma različiti.",
