    Effect of dietary levels of Zingiber officinale and Allium sativum on seminal lipid peroxidation and its correlation with semen indices in rabbit bucks.
    (Nigerian Society for Animal Production, 2018) Adeyemi, AA; Ola, SI; Ajao, BH; Yekini, SD; Oloyede, OJ
    To assess the effect of dietary levels of Zingiber officinale (ZO) and Allium sativum (AS) on seminal lipid perioxidation in rabbit bucks, twenty-eight (28) bucks aged 9 - 10 months were fed diets containing 0, 5, 10, and 15 ZO and AS g/kg diet for seven (7) weeks with four bucks per treatment. Semen was collected from the bucks weekly using an artificial vaginal. Samples of fresh semen were assessed for semen volume (ml), spermatozoa motility (%) and live sperm cells (%).

    Effect of male factor on the typology of vagina lumen epithelia cells in the female greater grasscutter
    (Animal Science Association of Nigeria, 2012) Ajao, BH; Ola, SI
    Fourteen female grasscutters were divided into the following treatments: No contact (NOC), Visual-Acoustic-Olfactory contact (VAOC), Acoustic-Olfactory contact (AOC) and Full Physical contact (FPC) with the male. The female animals were housed in pairs with all the treatments having a replicate each at the beginning of the study except VAOC, which had no replicate. Vagina smears were collected every other day from all the females for 7 days. The cells in the smear were classified into, intermediate, parabasal, superficial and metoestrus epithelial cell. In addition to the vagina epithelia cells the presence of leucocytes and mucous were also observed. Intermediate (21.00 – 97.00%) and parabasal cells (2.00- 58.00%) dominated the smear in all the treatment groups. Intermediate cells were highest in treatment group VAOC (60.33%) and lowest in FPC (41.0%) contrary to parabasal cells, which were highest in treatment, group NOC (44.00%) and lowest in VAOC (18.67%). Male influence seemed to exert no impact on the abundance of the vaginal epithelia cells in the treatment groups. In conclusion, male contact levels did not have any effect on the occurrence of vaginal epithelia cells. In addition, irregular presentation of vagina epithelia cells observed in the study indicated that the grasscutter could be an induced ovulator like the rabbit.

    Effects of dietary supplementation of ginger, garlic and onion on semen profile, haematological and serum antioxidant status of rabbit bucks raised in the dry season of the humid tropic
    (Faculty of Agricultural Sciences, Sabaragamuwa University, Sri - Lanka, 2022) Ajao, BH; Ola, SI
    Purpose: The study evaluated the semen, haematological and antioxidant status of rabbit bucks fed ginger, garlic and onion supplemented diets under a severely heat stressed condition. This is to evaluate the effect of heat stress and spice supplementation on seminal parameters, haematology and antioxidant capacity of rabbit buck raised in the tropics. Research Method: Fifty - five bucks were allotted to 11 treatments comprising of control diet, three each of ginger, garlic and onion at 5g, 10g and 15g/kg feed plus positive control diet. Seminal, haematological and antioxidant traits of the bucks and their pen's Temperature – Humidity index (THI) were observed for 8 weeks. Findings: THI (29.30 - 31.10°C) recorded during the study indicated the prevalence of severe to very severe heat stress. Heat stress impacted negatively more on sperm morphology than on other seminal parameters. Sperm cell motility, viability and abnormality were similar within supplemented groups and the controls. Semen volume and concentration were highest in animals fed garlic at 10 and 15g/kg feed respectively. Spice supplementation had no significant effect (p>0.05) on the haematology and total antioxidant capacity (TAC) of experimental animals. Originality/value: The study concluded that spice supplementation mitigated heat stress effect on sperm cell morphology and was not deleterious on haematology and TAC of the bucks.

    Impact of varying temperature-humidity index on the thermo-physiological, libidinal and seminal characteristics of male rabbits raised in the wet humid tropics.
    (Animal Science Association of Nigeria, 2021) Ajao, BH; Ola, SI
    The study was conducted to investigate the effect of the wet seasonal Temperature - Humidity Index (THI) at period of high ambient temperature (11am - 2pm) on the thermophysiology, libido and seminal parameters of a composite population of male rabbits. Thirty- three rabbit bucks housed separately in cages were monitored for 8 weeks in the wet season under varying THI. Weekly average of THI (27.61 - 30.36) observed was significantly different (p<0.05) and showed that the animals were either severely stressed or very severely stressed. Respiratory rate (142.07 - 328.42 cpm) and rectal temperature (38.58 - 39.73°C) of the bucks were progressively on the rise all through the experiment. Mount and ejaculatory latencies of the animals were significantly shorter (p<0.05) at period of high THI compared to lower THI contrary to the number of mounts which was higher at period of high THI. Semen parameters of the bucks were not negatively affected by the prevalent THI during the study. However, percentage semen morphological abnormality (15.82% - 17.71%) was significantly higher (p<0.05) at relatively high THI. The results of the study showed that rabbit bucks maintained their normal libidinal and seminal characteristics despite being raised under heat stress of varying intensity.

    Vaginal lumen cytology and peripheral sex hormone concentrations at different vaginal orifice statuses in the female greater Grasscutter
    (Animal Science Association of Nigeria, 2019) Ajao, BH; Ola, SI; Oyebanji, BO; Okukpe, KM; Alli, OI
    This study aimed to characterise the oestrous cycle of the female greater grasscutter (Thryonomys swinderianus) through investigating the pattern of exfoliated vaginal epithelia cells and peripheral sex hormone profiles in two different vaginal orifice status (open and close) displayed by the animal. Vaginal smears and blood samples were collected every other day from 12 non pregnantgrasscutterdoes for 7 days regardless of the vaginal orifice status. The cells in the smear were classified into parabasal, intermediate, superficial and metoestrus epithelial cell. Blood plasmawas assayed for estradiol (E2) and progesterone (P4) hormones. Irrespective of the vaginal status, intermediate cells were predominant with 54% and 56.7% for open and close vagina orifice, respectively. Superficial cells were15 % in open vagina status as against 9 % in the close vagina status. E2 concentration was significantly higher (P ˂ 0.05) in the open vagina status (6.75 vs 3.91 ng/ml) whereas P4 concentration was similar in both statuses. In conclusion, the similarity in the occurrence of vaginal lumen cells at open and close status indicated that the grasscutter could be an induced ovulator while the higher E2 concentration in the open vagina status could mean higher sexual receptivity at this stage.
