    Performance and meat quality attributes of broiler chickens fed onion skin extract and onion skin meal supplemented diets at the finisher stage
    (2018-06) Olusola, O. O.; Tella, A. K.; Olasunkanmi, A. A.
    Aims: This study was carried out to investigate the meat quality attributes of broiler chickens fed onion skin extract and onion skin meal supplemented diets at the finisher stage. Study Design: The experiment employed a complete randomized design; all data generated were subjected to analysis of variance, P=0.05. Place and Duration of Study: The study was carried out at the Teaching and Research Farm of the University of Ibadan, Ibadan, Nigeria, between October and December, 2016 Methodology: Four experimental diets were formulated such that treatment 1 contained the basal diet with synthetic antioxidant, treatment 2 was a basal diet without any antioxidant, and treatment 3 was basal diet supplemented with 30g/kg of onion skin extract while treatment 4 contained basal diet supplemented with 100 g/kg of onion skin meal. One hundred and sixty eight broiler birds were randomly assigned to four treatments of six replicates each at seven birds per replicate. They were raised for 8 weeks. At the expiration of the experiment, three birds from each replicate were randomly selected, tagged, fasted, weighed and slaughtered. Carcass and organs were obtained and weighed. Samples for cooking loss, pH and cooking yield were taken. Thiobarbituric Acid Reactive Substances (TBARS) was employed to assess the shelf stability of the product.

    Meat characteristics of bunaji, gudali and keteku breeds of cattle
    (2004) Okubanjo, A. O.; Omojola, A. B.; Ogunsola, O. O.; Adewunmi, M. K.; Ajiboro, O .G.; Alabi, G. F.; Babayemi, O. J.
    Carcass and meat quality traits of three breeds of cattle, which include Bunaji, Gudali and Keteku, were investigated. A total of five animals per breed were used for the study. The mean ages and live weights were not significantly different. Also, the mean carcass weight did not differ (p>0.05) significantly. The dressing percentage for Bunaji was lower (p<0.05) than for Gudali and Keteku. Back fat thickness was significantly higher (p<0.05) for Keteku and Bunaji than for Gudali while the rib eye area that was measured on the longissimus dorsi was higher in Keteku with 50cm2 while Gudali and Bunaji had 41cm2 and 33cm2 respectively. Texture of the lean meat was scored highest (p<0.05) in Gudali, followed by Bunaji while the least score was recorded for Keteku. However, the meat colour and marbling scores were not different (p>0.05) across the breeds. Shear force and cooking loss were least (p<0.05) in Keteku while Bunaji and Gudali had similar values (p>0.05) for both traits respectively.
