    Effect of successive ejaculations on the spermiogram of West African dwarf goats (Capra hircus L.)
    (Faculty of Veterinary Medicine, University of Zagreb, 2000) Oyeyemi, M. O.; Akusu, M. O.; Ola-Davies, O. E.
    Twenty healthy adult male (bucks) West African dwarf goats (WADG) aged between 2 to 4 years and with a mass of from 16 to 20 kg were used in this study. They were randomly assigned into four groups of five bucks per group. In group A, semen was collected once a week for a period of eight weeks, while in group B semen was collected twice a week for a period of eight weeks, once a day for 21 days in group C, and twice daily at an interval of five hours for 21 days in group D. Live body masses, height at withers, scrotal length and scrotal circumference were not affected by successive ejaculations. The ejaculate volume decreased as the frequency of ejaculations increased, although the decrease was not significant (Group A 0.44±0.07, B 0.41±0.08, C 0.38±0.07 and D 0.36±0.08 ml) while the ejaculate colour was either milky or creamy. Mass sperm movement showed swirling waves and scored 4 in all groups, while the percentage progressive motility ranged between 88.7±3.10 and 94.54±3.00%. Percentage of live spermatozoa (Group A 96.57±2.40, B 96.24±2.53, C 96.10±2.28 and D 96.10±2.50%) was not affected by successive ejaculations although a decrease in sperm concentration was observed as the number of successive ejaculations increased. There was a significant increase (P<0.05) in abnormal spermatozoa as frequency of ejaculation increased.

    Distribution of gastrointestinal helminthosis of small ruminants in Ibadan, South Western Nigeria: Role of traditional rearing system
    (Nature and Science, 2014) Adediran, O. A.; Adebiyi, I. A.; Uwalaka, E. C.
    In Nigeria, where the great majority of herds are managed traditionally, the search for feed and water results in scavenging livestock-raising methods. This often exposes such animals to high levels of infections, causing considerable losses. A survey was conducted during the short wet season to determine the prevalence and role of factors associated with small ruminant helminthosis in Ibadan region. A total of 880 sheep and goats were examined using standard parasitological procedures. The overall prevalence of helminthosis was 92.7%. Species prevalence of helminthosis was 96.1% and 89.3% in sheep and goats respectively. Sex prevalence was 94.1% and 87.8% in females and males respectively. Peri-urban prevalence was 96.0% while urban had 88.8% of mixed helminth infection. It was also observed that 42.5% and 57.7% of animal owners in urban and peri-urban areas lacked knowledge of anthelmintic used. Others, 20% and 30% of urban and periurban owners expressed some knowledge of existence of worms but believed that scavenging animals when infected have innate ability to seek medicinal herbs and plants to graze on. A total of 10% of all owners interviewed are aware that veterinary care should be given but only when the animals are obviously sick or fail to thrive. Our results reveal that the entire Ibadan region is endemic for gastrointestinal helminthosis and owners in the region believe that the best system for rearing small ruminants is the extensive management.
