| Four healthy bucks of the West African Dwarf breed aged between 24 and 30 months were used for this study. The bucks were first used as control and later as experimental animals upon being fed daily with oiled pumpkin plant for the period of six months. The objective of the study was to investigate the effect of the pumpkin plant on the morphology of the spermatozoa of the bucks. There were significant differences (p< 0.05) between the control and experimental values for both primary and secondary morphological spermatozoa abnormalities: the pyriform head has a control value of 6 (0. 42%) and post-feeding value of 0 (0%), the beat tail; 14(0.97%) and 2 (0.16%) for the control and post feeding values respectively. The curved mid piece: 17 (1.18%) and 1... |

| Four adult sexually matured and clinically healthy West African Dwarf (WAD) rams aged between 24 and 30 months were used for the study. The rams were first used as control and later as experimental animals upon being orally dosed with Euphorbia hirta extract at 400mg/kg body weight for 14 days. Semen samples were collected from the rams a day after the administration of the plant extra and seven days after. The objective of the study was to investigate the effect of Euphorbia hirta on the semen picture of WAD rams. There were significantly differences (P <0.05) in the semen picture as reflected in a reduction of sperm motility from 80% to 47.5% and live-dead ratio from 90.75% to 32.5% in the control and post-experimental stages of the study... |

| Histomorphometry of the testes and epididymis were carried out on the domesticated adult African great cane rat (Thryonomys swinderianus), also known as the grasscutter. The average weight and age of the cane rats used in the study were 1.93 ± 0.42 kg and 18.80 ± 1.39 months respectively. The mean relative volume of the germinal epithelium, interstitium and lumen of the seminiferous tubules of the cane rats were 68.54 ± 1.63%, 8.86 ± 0.85% and 21.40 ± 1.12% respectively. The mean diameter of the seminiferous tubules of the cane rats used for this study was 183.0 ± 11.06 µm. The ductal diameter of the caput, corpus and cauda epididymis were 207.4 ± 7.41 µm, 237.8 ± 10.15 µm and 274.2 ± 9.00 µm respectively, being statistically different (p< 0.05). The... |

| Morphometric studies were carried out on the horns of 60 Uda rams. The mean values for the relative horn weight, weights of the right and left horns were 0.67%, 219.5g and 208g respectively. The mean values for the lengths of the right and left horns and the horn base circumference were 25.6cm, 27.4cm and 17.4cm respectively. There were significant differences (p< 0.05) between the lengths of the right and left horns; and between the weights of the right and left horns. There were also strong positive correlations between the body weight of the animals and the length of the horns. A graph of the length of the right horn against the body weight of the animals with a significant deviation from zero at 95% confidence intervals yielded a slope value of... |
