Item Effect of cinnamon powder on the shelf life and quality attributes of zobo drinks.(Department of Science Education, Federal University of Technology, Minna, Nigeria., 2020) Salami, Khadijat Onozare; Badmos, A.A.; Lawal, M.O.; Kayode, Rowland M.O.; Balogun, M.A.; Lawal, A.O.Zobo is a highly acceptable beverage in West Africa with limited shelf life. This study determined the sensory and microbial attributes of Zobo drinks in storage when blended with cinnamon, a natural preservative. A Completely Randomized Design of six treatments (C0, C1, C1.5, C2, C2.5 and C3) was used, wherein the cinnamon content was varied, from 0 to 3g per 200 ml zobo drink. The pH, sensory properties, and Total Viable Count (cfu/ml) of the Zobo samples during a seven-day storage were monitored. The results revealed that pH of sample decreased with higher cinnamon content and days of storage, while the control sample increased in pH with storage. The taste scores of the zero cinnamon control was highest on the day of production, but decreased considerably with storage. The C3 (highest cinnamon level) sample was however highest in aroma, taste and general acceptability for the seven storage days. The C3 zobo sample inhibited microbial growth most throughout the days of zobo storage. It was concluded that cinnamon is a potent additive and preservative that improved the sensory properties and increased the shelf life by inhibiting microbial spoilage of zobo drink. The use of cinnamon additive at 3 g for every 200 ml of zobo drink is thus recommended.Item Effects of Vernonia amygdalina Leaf Meal on Male Hormone and Reproductive Organ Weight of Thryonomys swinderianus(Bioscience Research Journal, Nigerian Society for Experimental Biology, 2020) Okukpe, Kehinde Matthias; Ajayi, A.S.; Adeyina, Adebisi Olusegun; Sanni, Kafayat Modupeola; Adeyemo, A.D.; Lawal, M.O.; DeCampos, John Sunday; Ajao, Babatunde H.Item Haematology and Blood Biochemistry of West African Dwarf Bucks Fed Graded Levels of Black Plum (Vitex doniana) Leave Meal(Animal Science Association of Nigeria and National Institute for Animal Science, 2018) Okukpe, Kehinde Matthias; Ayangbade, S.A.; Adeyina, Adebisi Olusegun; Alli, Oluwasayope Ibidapo; DeCampos, John Sunday; Aderibigbe, T.A.; Lawal, M.O.Item Impact of Black plum (Vitex doniana) Leaf Meal on Blood Biochemistry, Hormone and Cholesterol Level of West African Dwarf Bucks(Animal Science Association of Nigeria, 2019) Okukpe, Kehinde Matthias; Lawal, M.O.; Sanni, Kafayat Modupeola; Adeyina, Adebisi Olusegun; Alli, Oluwasayope Ibidapo; DeCampos, John Sunday; Aderibigbe, T.A.Item Influence of dietary supplementation of Crassocephalum crepidioides leaf on growth, immune status, caecal microbiota, and meat quality in broiler chickens(Springer Nature, 2021) Adeyemi, K.D.; Sola-Ojo, F.E.; Ajayi, F.B.; Isamot, H.O.; Lawal, M.O.The effect of dietary supplementation of Crassocephalum crepidioides leaf powder (CCLP) in comparison with oxytetracycline and butylated hydroxyanisole (BHA) on growth, caecal microbiota, immune status, blood chemistry, carcass traits, meat quality, and oxidative stability in broiler chickens was evaluated. Two hundred and eighty 1-day-old Arbor acre chicks were randomly assigned to a basal diet containing either no additive (control, CON), 400 ppm oxytetracycline + 150 ppm BHA (ANTIBIOX), 1000 ppm CCLP (CCLP-1), or 2000 ppm CCLP (CCLP-2) for 42 days. Each dietary group had seven replicates with ten birds per replicate. Supplemented birds had higher (P < 0.05) feed efficiency, hemoglobin, and hematocrit compared with the CON birds. Diet did not affect feed intake, body weight gain, splenic interleukin-1β, interleukin-6, interleukin-10, and serum IgM. The CCLP-2 birds had lower (P < 0.05) serum total and LDL cholesterol than did birds fed other treatments. Salmonella spp. and Escherichia coli counts and serum IgG were higher in the CON birds than in the supplemented birds. The ANTIBIOX birds had lower (P < 0.05) Lactobacillus spp. count, and higher (P < 0.05) E. coli count compared with the CCLP-supplemented birds. Carcass, muscle pH, and cook loss were not affected by diet. The CON breast meat had higher drip loss and lower redness than did the breast meat of the supplemented birds. Carbonyl content and TBARS value in the thigh and breast meat of the supplemented birds were lower (P < 0.05) than those of the CON birds. These results infer that CCLP exhibited antioxidant and antimicrobial properties that were comparable to those of BHA and oxytetracycline in the diet of broiler chickens.
