Item 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, OJTo 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 (%).Item 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, SIFourteen 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.Item Effect of plumage colour on carcass characteristics and meat quality of Nigeria local turkeys(Animal Science Association of Nigeria, 2021) Yusuff, AT; Saheed, KR; Badmos, AA; DeCampos, JS; Ajao, BH; Aremu, JOThis study examined the effect of plumage colour on carcass characteristics and meat quality of Nigeria local turkeys. Nine 14weeks local turkeys of different plumage colour (3 blacks, 3 white, and 3 mixed colour) were studied during the experiment. The birds were allotted into treatments based on the 3 plumage colours. Data taken were carcass weight, dressing percentage, prime cuts and relative organs’ weights, pH, drip loss, cook loss, meat colour and sensory attributes of cooked meat. Data collected were subjected to analysis of variance using SPSS version 25. The result obtained revealed that plumage colour affects the pH of turkey meat with a significantly higher carcass pH (5.68) from the mixed colour plumage group. It was also noted that, carcass weight, prime cuts and relative organ weight showed no significant difference (P > 0.05) irrespective of plumage colours. Similarly, the drip loss, cook loss and meat colour (lightness, redness and yellowness) were not influenced by plumage colour of the turkey while the sensory evaluation revealed that black plumaged birds group were more juicy, and had the best aroma and overall acceptability compared to others. It is therefore concluded that plumage colour affects the pH and juiciness, aroma and overall acceptability of Nigeria local turkey meat.Item 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, SIPurpose: 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.Item Effects of human menopausal gonadotrophin (HMG) on plasma hormonal profile and egg production in local guinea hens(Animal Science Association of Nigeria, 2018) Alli, OI; Toye, AA; Adeyina, AO; Ayorinde, KL; Okukpe, KM; Ajao, BHCommercial production of guinea hens is limited because they are known to be seasonal breeders, with little or no eggs during the dry season. Natural hormones or their analogue have gained special appeal and usage as means of improving the reproductive performances of farm animals due to the health concerns associated with use of synthetic hormones. Human menopausal gonadotrophin (HMG) consists of follicle stimulating hormone (FSH) and luteinizing hormone (LH) and is aimed at improving reproductive performance. Five doses (0, 6, 12, 18 and 24 IU) of HMG were administered to guinea hens in two phases (dry and rainy seasons) to evaluate the effect on the follicle stimulating and luteinizing hormone profile and egg production for a period of eleven months. The effects were monitored during the administration and post administration periods. Egg collection was done daily and blood was collected from the birds on fortnight basis to determine concentration of FSH and luteinizing hormone LH. Data collected were subjected to analysis of variance appropriate for 2x2x5 factorial design. LH and FSH concentrations were correlated with egg production. Results indicated that both LH and FSH concentrations were higher (P<0.05) in the rainy season and during the period of post administration of HMG while doses of HMG had no effect (P>0.05) on the concentration of both hormones. LH and FSH were positively correlated in both seasons but the correlation was highly significant (P<0.01) only in the rainy season. Low negative correlation existed between egg production and LH in the dry season while positive, low and nonsignificant (P>0.05) correlation was observed in the rainy season. In conclusion, administration of HMG could be used to boost egg production in guinea hens.Item Effects of Vernonia amygdalina leaf meal on male hormone and reproductive organ weight of Thryonomys swinderianus(Nigerian Society for Experimental Biology, 2020-02-29) Okukpe, KM; Ajayi, AS; Adeyina, AO; Sanni, KM; Adeyemo, AD; Lawal, MO; DeCampos, JS; Ajao, BHGrasscutter (Thryonomys swinderianus) feeds mainly on green plants especially those with succulent stems. Vernonia amygdalina the most prominent species and one of the tropical tribes of the family Asteraceae, it is so unique that every part of it has an economic importance and has been shown to be valuable nutritionally. The aim of the experiment was to determine the effect of administering Vernonia amygdalina leaf diets on testis weight and reproductive hormones of grasscutter (Thryonomys swinderianus). A total of eighteen male weaner grasscutters weighing between 281.33g and 304.21g were allotted to six treatments in a completely randomized design (CRD). The animals in treatment A (control) were given feed without Vernonia amygdalina (VA) leaf meal, B had 1g VA/kg feed, C had 2g VA/ kg feed, D had 3g VA/kg feed, E had 4g VA/kg feed and F had 5g VA/kg feed. Feeding was done for a period of seven (7) weeks and at the end of the experiment, two animals were selected per treatment after starving for about 10hours, sedated with diethylether soaked in cotton –wool and placed close to nostril to reduce handling stress before slaughtering by severing the carotid artery and the jugular vein. Blood was collected into plain bottles, centrifuged at 500rpm for 5minutes to obtain serum for hormonal tests. The hormones tested for were luteinizing hormone, follicle stimulating hormone, oetrogen and testosterone. The penis and testis were weighed and recorded after excision and removal of adhering fats. Data collected were subjected to analysis using SAS 2008 model and mean differences separated with Tukey studentized range test. The reproductive hormones and testis weights were significantly (p<0.05) affected by the Vernonia amygdalina inclusions. It showed that Treatment F had the highest luteinizing hormone while treatment A had the lowest. Treatment D had the highest follicle stimulating hormone while treatment E had the lowest. Treatment A had the highest oestrogen level while treatment B had the lowest. Treatment A had highest testosterone while treatment B had the lowest. It was observed that the addition of Vernonia amygdalina leaf meal as feed supplement of grasscutter had no adverse effect on their reproductive parameters as could be observed from the reproductive organ weight and reproductive hormone values of the animal.Item Effects of Vernonia amygdalina Leaf Meal on Male Hormone and Reproductive Organ Weight of Thryonomys swinderianus(Nigerian Society for Experimental Biology, 2020) Okukpe, KM; Ajayi, AS; Adeyina, AO; Sanni, KM; Adeyemo, AD; Lawal, MO; DeCampos, JS; Ajao, BHGrasscutter (Thryonomys swinderianus) feeds mainly on green plants especially those with succulent stems.

The objective of the experiment was to assess the effect of clove extract on hormone profile of West African Dwarf (WAD) bucks. One hundred and fifty WAD bucks with average weights of 10kg were randomly assigned to five treatments with 30bucks per treatment in a completely randomized design. Treatment A (control) and B were subcutaneously administered 0.1mL/kg of normal saline solution and 0.1mL/kg sildenafil citrate, respectively. Treatments C, D and E were administered 0.1, 0.2, and 0.3mL/kg of clove extract, respectively. The result showed a significant increase in WBC while PCV decreased with corresponding increase in extract doses. The extracts also significantly cause a reduction in creatinine, alkaline phosphatase (ALP) and aspartate aminotransferase (AST) with a significant increase in serum urea and alanine aminotransferase (ALT). There were significant increase in serum testosterone and prolactin while follicle stimulating hormone and luteinizing hormone were reduced. It was therefore concluded that subcutaneous administration of syzygium aromaticum extract could enhance sexual function at low doses of 0.1mL/kg body weight of bucks with no observable tissue damageItem 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, SIThe 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.Item Milk yield and Milk Composition of West Africa Dwarf Does as influenced by Body weight and Body Temperature(Kebbi State University of Science and Technology, Aliero, Nigeria, 2022-01-01) Yusuff, AT; Adeyemi, AA; Lawal, MO; DeCampos, JS; Ajao, BH; Aremu, JOThe study was conducted to determine the effect of bodyweight and body temperature on milk yield and milk composition of West Africa Dwarf (WAD) does. A total number of sixteen lactating WAD does of different body weight were selected for the experiment. The bodyweight and body temperature of the does were taken before every milking period which lasted up to 8 weeks. Milk sample from each doe was subjected to milk composition analysis using milk analyzer. The bodyweight of the does and its corresponding milk yield were grouped into four classes (12 -15 kg, 15.1 -18 kg, 18.1-21 kg, 21.1-24 kg) while the body temperature and its corresponding milk yield and properties were portioned into three ranges (low: 36.10 – 37.00 oC; medium: 37.10 – 38.00 oC; high: 38.10 – 39.00 oC). The data obtained were subjected to one-way analysis of variance of completely randomized design. The results revealed that bodyweight significantly (P<0.05) affects milk yield but not milk composition while body temperature range of 38.10-39.00 oC influences higher milk yield (580.60 ml) It is therefore concluded that WAD does has a relatively stable milk composition irrespective of body temperature or bodyweight while the does of higher body weight produce more milk. It is therefore recommended that body temperature and bodyweight should be among the considerable criteria when selecting WAD goats for dairy purposeItem Repeatability and heritability estimates of five rabbit genotypes at various ages.(Nigerian Society for Animal Production, 2015) Olupitan, E0; Chineke, CA; Ajao, BHThis breeding experiment was carried out at the Rabbit Unit, Teaching and Research Farm, Federal University of Technology, Akure (FUTA) between 2009 and 2010. Data on litter traits such as individual kit weight (IKW), average litter weight (ALW), litter weight (LTW), litter size (LTZ) of the animals were collected. Data on the litter traits were taken at birth, 21, 35 and 56 days of age from 13 progenies and 5 parental genotypes. Heritability estimates due to dam ranged from very low value of 0.00014 (IKTW) at 21 days to a very high value of 0.774 (LTW) at 35 days. Repeatability followed similar trend but ranged from extremely low value of 0.00004 (IKW) at 21 days to medium value of 0.194 (LTW) at 35 days. The study show that selection could be better made for the traits at 35 days of age as that would bring improvement for the traits in question. The results also indicated the superiority of the dam over the sire in selection for improvement of the traits.Item 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, OIThis 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.
