Abstract
Umesiobi, D.O. 2004. Functional integrity of boar spermatozoa and sow fertility using raphia (Raphia hookeri) palmwine plus ‘nche’ (Saccoglotis gabonensis) urban extender. J. Appl. Anim. Res., 26: 53–56.
Ninety-six (2.5 year) cycling, non-lactating Large White sows and twelve (2 years) Large White boars were used in an AI programme to study the effects of raphia (Raphia hookeri) palmwine alone (RP) or with ‘Nche’ (Saccoglotis gabonensis) Urban (RPS) semen extender as compared with a conventional Cornell University extender (CUE) on boar semen viability and fertility of inseminated sows. RPS semen extender gave the highest sperm motility, live sperm per cent, sperm concentration and normal apical ridge with least abnormal sperm per cent, damaged and missing apical ridge and loose acrosomal cap. CUE, RP and no extender followed in that order for these characteristics. Same pattern was observed in sows' farrowing rate and total and live piglets born per sow. Thus RPS is recommended for boar semen dilution programme.
