the main purpose of this study was to evaluate the influence of the photoperiod on the seminal traits of crossbreed wool-producing rams throughout on year period. for the effect of photoperiod two periods were considered: decreasing daylight length (summer and autumn) and increasing daylight length (winter and spring). for the study 5 baluchi × moghani (bl×mg) and 5 arkharmerino × moghani (am×m...

The objective of this research was to determine the effect of vaccination against porcine circovirus type 2 (PCV2) on ejaculate characteristics, PCV2-specific antibody titers in serum, viremia, and viral shedding in the semen of PCV2-positive boars. Before vaccination, all boars were confirmed by PCR to be naturally infected with PCV2. The boars were vaccinated with a commercial killed vaccine ...

in order to determine iron and lead content of seminal plasma in water buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls. the semen characteristics were evaluated; its iron and lead content were estimated by atomic absorption spectrophotometer. the iron and lead content of the seminal plasma (mean ± sem) was recorded as...

Variations in the ejaculatory abstinence durations suggested by different guidance bodies have resulted in a growing concern among researchers over what the concise period of ejaculatory abstinence for an optimal semen sample ought to be. Several studies have been undertaken to examine the association between the length of sexual abstinence and semen characteristics. Not all studies, however, h...
