    Evaluation of meat characteristics of West African dwarf rams fed graded levels of fungal treated maize cobs
    (Animal Science Association of Nigeria, 2015-09) Akinfemi, A.; Ososanya, T. O.; Aderiye, J. A.
    An experiment was conducted to determine the impact of fungal treated maize cob (FTMC) used as supplement on the carcass characteristics of West African dwarf (WAD) ram. Maize cob treated with Pleurotus tuber reguim was supplemented at 0, 10, 20, 30 and 40% w/w to complete feed mixtures (CFM). A total of 20 grower rams with an average age of ten months were selected for the evaluation of carcass characteristics. The animals were starved of feed for 16 hours, weighed, stunned, slaughtered and properly bled. The thoroughly bled carcass were dressed and eviscerated. The dressed carcass were cut into half carcasses, left half was dissected to determine internal offal while the other half was cut into primal cuts: neck, rack, loin, flank and leg. The final body weight (27.33kg), mean weight gain (11.58kg), rib eye area (10.70%) and dressing percentage (50.11%) were significantly better far rams on treatment 5 and in general all rams on FTMC supplemented diets compared with the control. Similarly hot carcass weight increased with supplementation from 9.55kg (T)) to 11.99kg (T2). Variations in rack and kidney weights as affected by treatments was not significant (P>0.05). Treatment effect on shoulder weight was significant (P<0.05) far animals on FTMC compared with the control groups. However, no significant (P>0.05) differences was observed far those 011 diets 3, 4 and .5 It can be concluded from the results obtained in this experiment that WAD rams fed FTMC improve the dressing percentage and rib eye area without any noticeable detrimental effect on the organ parts.

    Effect of different feeding patterns on carcass characteristics and primal cuts of broilers chickens
    (Sciencedomain International, 2017) Adeyemo, G. O.; Badmus, R. T.
    An experiment was conducted to assess carcass characteristics and offals of broilers fed on varying forms of feeding regimes. 240, 1-day old broiler chicks-were randomly allotted to four feeding regimes each in 6 replicates of 10 birds per replicate designated as treatments as follows: ad libitum, twice a day split feeding, thrice a day split feeding and 3 hours restriction feeding. Birds were slaughtered on day 42 to determine the relative weights of the primal cuts and visceral organs. Significant differences (P<0.05) were obtained on carcass parameters' measured. Birds on ad libitum feeding had the highest bled (87.6), dressed (61.9), eviscerated (67.0) and de-feathered weights (82.5%) while the least values were obtained from birds fed thrice a day, though the values were not significantly different (P>0.05) from those of birds on twice a day split feeding regime. Birds fed ad-libitum had the highest drumstick weight (8.84%) and wing percentages (6.73%). The neck percentages were 4.47, 4.22, 3.04 and 2.84 for ad-libitum, twice a day, 3 hour restriction and thrice a day feeding respectively. Liver, abdominal and crop weights were similar (P>0.05) for ad libitum and twice feeding regime but were different (P<0.05) from thrice and restricted feeding regime. Broilers on ad libitum and twice a day feeding regimes gave the best results for carcass, primal cuts and organ weights measured.
