Item Influence of sex and processing methods on physicochemical and organoleptic quality of rabbit meat(2012-08) Apata, E. S.; Koleosho, T. S.; Apata, O. C.; Okubanjo, A. O.The objective of this study was to determine the influence of sex and processing (Cooking) methods on pysicochemical and organoleptic properties of rabbit meat. Thirty-two matured rabbits of different breeds (16 males and 16 females) were used for this study. The rabbits were purchased from Abeokuta and transported to Olabisi Onabanjo University, Yewa Campus, Ayetoro, where this study was conducted. The rabbits were rested for 2 weeks, starved for 16 h, then slaughtered and dressed conventionally. Their carcasses were assigned randomly to four cooking treatments viz: frying, broiling, roasting and stewing. 100 g of meat samples were excised from leg cuts of rabbit carcasses from each treatment and cooked for 20 min after which physical, chemical and sensory attributes of rabbit meat were determined. Data generated were subjected to analysis of variance (ANOVA) for completely randomized design with 4x2 factorial arrangement (P = 0.05). The results showed that cooking loss, thermal shortening and shear force values were higher (P < 0.05) in fried rabbit meat, while water holding capacity and cooking yield were higher (P < 0.05) in stewed rabbit meat. Moisture and protein contents were higher (P < 0.05) in stewed rabbit meat while, they were lower (P < 0.05) in fried rabbit meat. Meat from female rabbits had higher (P < 0.05) proximate component values except nitrogen free extract values that were higher (P < 0.05) in male rabbit meat. The results revealed that colour and flavour scores were higher (P < 0.05) in fried rabbit meat, followed by boiled ones also, fried rabbit meat were accepted more than broiled, roasted and stewed ones. Also, male rabbit meat was highly relished than female rabbit meat in this study. It was suggested therefore, that frying and broiling methods be employed, also male rabbits be preferred if rabbit meat is to be processed since fried and broiled rabbit meat as well as meat from male rabbits were accepted more than these from female rabbits, in this study.Item Sex differences in biochemical contents of telfaira occidentalis hook F.(WFL Publishers, 2006) Ajibade, S. R.; Balogun, M. O.; Afolabi, O. O.; Kupolati, M. D.In order to evolve ways of early sex identification in Telfairia, the biochemical contents of leaf, vine and root of male and female plants were determined in three genotypes. Female plants had significantly higher concentrations of protein and fat while the male plant was higher in fibre, as hand all the anti-nutrients. The concentration of trypsin inhibitor was most influential in distinguishing between the sexes especially for root and vines while the fibre content was most important for the leaf. Leaf fibre content is therefore recommended for sex identification since it can be easily determined at any stage of plant development without destroying the whole plant.Item Sex comparism of white Fulani cattle blood profile in Southwestern Nigeria(Animal Science Association of Nigeria, 2013) Ladokun, A. O.; Oyebode, O. A.; Abiona, J. A.; Ososanya, T. O.Sexual dimorphism has been established in the brain regions of farm animals and poultry, but for their blood, reports do not agree as to differences at the same age. While some reports show no differences except for pregnant and lactating females, others indicate Otherwise. This study was carried out to investigate the blood of white Fulani breed of cattle in southwestern Nigeria if there could be differences at same mature age (4yr). A total of 100 cattle were used consisting of 50 bulls and 50 cows. Full haematology was investigated using the Vet AutoHaemoanalyser machine. Some serum metabolites were also investigated including total Protein, Albumin and total cholesterol. Data obtained were subjected to one-way analysis of variance (ANOVA). The results show that white blood cell count (WBC) was significantly (P<0.05) higher in females (17.23±1.08) than in males (12.25±0.77). Mean Corpuscular haemoglobin concentration (MCHC) also showed sex differences with females having higher and significant (P<0.05) average value (33.8±0.19) than males (32.6±0.24). The results from Serum analysis show that bulls (with 37.8±0.54) have higher and significant (P<0.05) Albumin values than cows (34.9±0.29). Though the results obtained in this study fall within normal ranges for this species, it however does not indicate any specific sex effect for this breed.
