black bengal goat is the heritage and one of the potential genetic resources of bangladesh. genetic and phenotypic parameters for semen characteristics and their relationships with scrotal circumference in black bengal bucks were estimated in this experiment. genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanen...

Many libraries offer open access publishing funds to support authors in paying article processing charges (APC) levied by some OA journals. However, there are few standard practices for managing or assessing these funds. The Open Access Working Group (OAWG) of the Canadian Association of Research Libraries (CARL) was asked to investigate and articulate best practices for successful open access ...

Recently, D-aspartic acid (d-Asp) has been suggested as being involved in mechanisms regulating reproduction activity in animals and human. In this study we analyzed the effects of DL-Asp oral administration on sperm production in the rabbit. Bucks from 60, bred in a genetic centre and used for semen production, were divided in 2 subgroups of 6 individuals. The treated group was fed with a conc...

Ten male Merghoz goats with initial live weights of 29.2 ± 1.2 kg (Mean±SE) were used to investigate the effect of natural changes in photoperiod on dry matter intake (DMI) and reproductive activity during a 365 day study. The bucks were housed in individual pens, under natural daylength condition at west of Iran, Kermanshah (34˚ 18¢N and 47˚ 3¢E and 1420 m above sea level). A diet was offered ...
