Item Male Reproductive System: Chapter two of the Text Book Introductory Theriogenology- Raheem A.K.(University Press PLC, Three Crowns Building, Jerico, P.M.B. 5095, Ibadan, Nigeria, 2017) Raji L.O.Male Reproductive SystemItem Reproductive pathology of experimentally induced lead poisoning in Red Sokoto Buck: Protective effect of tiger nut (Cyperus esculentus).(Faculty of Veterinary Medicine, Assiut University, Assiut, Egypt., 2020) Adam, M; Esievo, K.A.N.; Bisalla, M.; Ayo, J.O.; Aliyu, A.I.; Akanbi, O.B.; Baba, A.Y.; Raji L.O.; Salleh, A.Tiger-nut (Cyperus esculentus) is a crop that belongs to family Cyperaceae which produces rhizome and tuber that are small spherical in shape. The tubers have aphrodisiac, carminative, diuretics and several health benefits. The aim of the present study was to investigate the influence of methanol extract of tiger nut on the male reproductive pathology of chronic lead poisoning in Red Sokoto buck. The tiger nut was extracted using 95% methanol by cold extraction method. Four adults Red Sokoto bucks (12 to 25 kg) were randomly grouped into four. Group I was administered distilled water (200 mL). Group II was administered lead acetate (200 mg/kg) only. Group III was administered methanol extract of tiger nut (200 mg/kg) and lead acetate (200 mg/kg). Group IV was administered tiger nut (200 mg/kg) only. Evaluation of semen characteristics (semen motility, semen concentration, ejaculate volume and semen pH) were determined by standard method. The serum testosterone changes were determined using commercial kits. The lead acetate (200 mg/kg) group II showed decreased semen characteristics parameters while tiger-nut (LA + TN) group III showed improved values of the semen characteristics. However, the semen characteristics values on the distilled water (DW) group I and sole tiger nut (TN) group IV showed a good semen characteristics values. In conclusion the methanol extract of tiger nut contained antioxidant properties that significantly influence a protective role in ameliorating the pathological effect of lead poisoning in male reproductive pathology in Red Sokoto goat.Item Scrotal circumference as a Parameter for Breeding age in the West African Dwarf goat bucks.(Turkish Science and Technology, 2015) Raji L.O.; Ajala O.O.This study evaluated the correlation between scrotal circumference (SC), body weight (BW) and body condition score (BCS) in relation to breeding age in West African Dwarf (WAD) bucks. A total of 320 WAD bucks from birth to 15 months of age from various farms in Ibadan, Nigeria, were studied. They were grouped as A-birth to 3, B-4 to 7, C-8 to 11 and D-12 to 15 months old respectively, comprising of 80 bucks per group. Semen was collected from 10 randomly selected bucks in each group and analysed. Results showed positive correlation between SC and age; SC increased with age; and at about 8 months of age and over, a consistent SC of 17 cm–18 cm was observed. BW also increased with age; BW significantly affected SC. Also, at 8 months of age and over, SC of 17 cm-18 cm was observed from 9 kg BW and above. However, the correlation between SC and BCS was low and not significant. Semen analysis revealed the best semen quality for groups C and D bucks. In conclusion, we suggest that WAD bucks of 8 months and above, with at least SC between 17 cm–18 cm and of over 9 kg BW, could be used to breed does successfully on the farm.Item Testicular Ultrasound as a breeding soundness examination and biometric tool for West African Dwarf bucks.(National Agricultural and Food Center – Research Institute for Animal Production, Nitra, Slovakia., 2016) Raji L.O.; Ajala O.O.; Ameen S.A.This study was carried out to evaluate testicular ultrasound as a breeding soundness examination (BSE) and biometric tool for West African dwarf (WAD) buck goats. Twelve bucks of proven breeding capability were selected for this purpose. Scrotal circumferences of these animals were measured using a flexible tape. Testicular ultrasound was carried out on the transverse and longitudinal planes on the right and left testes. The electronic caliper on the ultrasound machine was used to measure the testicular length, height and width from which the testicular volume was calculated using the prolate ellipsoid formula (PEF), the prolate spheroid formula (PSF) and the Lambert formula (LF). These were compared with the true testicular volumes obtained by the water displacement method (WDM). Results showed that the mean scrotal circumference was 17.48 ± 0.31 cm. Testicular echo-texture revealed homogenously greyish parenchyma with hyper-echoic mediastinum line in the middle. The scrotal wall appeared as a hyper-echoic semi-circular border line at the caudo-dorsal portion of each testis. The heads of the epididymides of the right and left testes appeared as a small roundish hypo-echoic structure on the caudo-ventral and cranio-ventral portions of each testis respectively. Results of the parameters taken using the electronic caliper revealed that the mean width of both testes was 7.24 ± 0.16 cm. There was a high correlation between scrotal circumference and width of both testes measured on the ultrasound machine. There were no statistically significant differences between the means of the left and right testes length, height and width. Similarly, differences were not statistically significant in the testicular volumes obtained using the PEF and WDM. However, the testicular volumes obtained using the PSF and LF were significantly higher than the true testicular volumes obtained using the WDM. PEF was the best of the three formulae in estimating WAD buck testicular volume. In conclusion, we suggest that testicular ultrasound will be valuable in the BSE and in measuring the important biometric parameters in WAD buck goatsItem The effect of aqeous Aloe vera gel extract on serum mineral composition of Red sokoto bucks (Maradi).(Published by Nigerian Society for Animal Production., 2015) Ameen S.
