“…The highest volume was observed in autumn and the lowest in spring, which is in agreement with reports by other researchers (Wolf and Smital, 2001;Kozdrowski and Dubiel, 2004;Frydrychová et al, 2007). Semen plasma is a product of accessory glands (Pérez-Pé et al, 2001).The increasing activity of the accessory sex glands in autumn observed by Ciereszko et al (2000) could explain the higher volume ejaculated in this season.…”

-The objective of this study was to evaluate the effects of season, natural photoperiod, and room temperature at the housing facility on boar semen characteristics in Uruguay (34º66'S; 56º29'W). For this purpose, 117 ejaculates, obtained from eight adult males collected through 12 consecutive months, were assessed for sperm viability, DNA integrity, abnormalities (total, primary, and secondary), ejaculate volume, and sperm concentration. Viability, total and primary abnormalities, volume, and sperm concentration were affected by season. Sperm viability, volume, and sperm concentration were affected by natural photoperiod. In general, autumn and the decreasing photoperiod had a negative impact on most of the semen characteristics, except for volume. Housing temperature did not affect semen characteristics. In boars living in temperate climates, semen quality is negatively affected during autumn and is related to photoperiod changes; however, the effects of temperature changes in housingdo not affect these seminal characteristics. In this scenario, seasonal differences in semen quality may have a negative effect on sow fertilization. Consequently, semen quality control especially during autumn is imperative for the best boar selection to be used for insemination purposes. Seasonal differences in semen quality may have a negative effect on sow reproductive performance. This issue will be addressed in a future investigation.

The objective of this study was to determine the effect of age and reproductive season on selected properties of semen from the arctic fox, Alopex lagopus L. The experiment used 40 ejaculates collected manually from 6 animals (3 foxes aged one year and 3 foxes older than three years). Statistically less semen (0.39 cm 3 ) was collected from the young compared to the older animals, and the ejaculates obtained were characterized by higher concentration of spermatozoa (195.04 x 10 6 /cm 3 ). In turn, sperm acrosomal extracts from the older animals contained statistically more acrosin (6,4 mU/10 6 spermatozoa). In the sperm acrosomal extracts prepared during the first semen sampling, the mean acrosin activity did not exceed 2.3 mU/million spermatozoa. At subsequent semen sampling dates, the activity of the analysed enzyme increased to reach 7.72 mU/million spermatozoa. In the extracts obtained from the semen collected at the end of the breeding season of arctic foxes, the acrosin activity again reached a value obtained at the beginning of the season.

“…Boars of different breeds or hybrids may produce ejaculates with different physical characteristics (Bertani et al, 2002;Kondracki, 2003;Wysokińska & Kondracki, 2005). Hybrid boars generally produce ejaculates with more favourable traits than purebred boars (Ciereszko et al, 2000;Kondracki et al, 2003;Szostak, 2003). In a study by Milewska (2007), ejaculate volume in Pietrain×Duroc and Duroc×Pietrain crossbred boars ranged from 238 to 245 mL, and sperm concentration from 343,000 to 356,000/mm 3 .…”

The aim of the study was to determine the effect of growth rate and lean meat content in Pietrain×Duroc and Duroc×Pietrain hybrid boars on their semen characteristics. On the basis of the results of performance testing carried out on the 180 th day of life, the boars were divided into four groups according to their daily weight gain (I: 750-800 g; II: 801-850 g; III: 851-900 g; and IV: >900 g), and additionally into three groups according to lean meat content (I: 60-61%; II: 62-63%; and III: >63%). Ejaculates were evaluated for the following characteristics: volume, sperm concentration, percentage of sperm with progressive movement, number of sperm with progressive movement per ejaculate and per insemination dose, primary morphological defects and number of insemination doses obtained per ejaculate. Neither high daily weight gain in the hybrid boars during the rearing period nor their high lean meat content had a negative effect on their semen characteristics.
