    Effect of stocking density on the perfonnance, carcass yield and meat composition of broiler chickens
    (Sciencedomain International, 2016) Adeyemo, G. O.; Fashola, O. O.; Ademulegun, T. I.
    Broiler chickens require adequate feed intake and uninterrupted emission of heat for intensive growth. An eight-week feeding trial was conducted to investigate the effects of stocking density on performance, carcass yield and meat composition of broilers. A total of 240 one-day old Arbor acre broiler chicks were randomly allocated to three stocking densities: Lower stocking density (LSD) of 10 birds/m2; Recommended stocking density (RSD) of 12 birds/m2; and Higher stocking density (HSD) of 14 birds/m2 respectively, with 4 replicates each having 20 birds per replicate. Feed and water were supplied ad libitum. Final live weight(FLW); Feed intake(FI); Feed conversion ratio(FCR); Mortality(%); Dressed weight(%); Prima cuts(%); Abdominal fat(%) and meat composition were assessed. Data were subjected to descriptive statistics and ANOVA °°=0.05. Birds on HSD had numerically higher FLW (2262.80 g), better FCR (2.08) that was similar to that of LSD (2.07) and significantly lower mortality (0.00%). The values of the prime cuts (thigh, drumstick and breast), abdominal fat and meat protein were similar between birds on LSD and HSD. Up to stocking density 14birds/m2 broiler chickens' performance and carcass characteristics were not negatively affected.

    Effect of stocking density on the welfare, haematology and serum biochemical indices of broiler chickens
    (Society of Animal Science, Department of Livestock & Avian Science, Wayamba University of Sri Lanka, 2011) Adeyemo, G. O.; Fashola, O. O.; Ademulegun, T. I.
    Influence of stocking density on welfare parameters (Litter temperature and moisture, microbial load, Gait score), haematology and serum biochemical indices (as indicators of condition of stress) on broilers was studied in an eight week feeding trial. A total of 240 one- day old Arbor acre broiler chicks were randomly allotted to three treatments (stocking densities) with 4 replicates each having 20 birds per replicate. The stocking densities rates were 10birds/m2, 12birds/m2 and 14 birds/ m2 respectively. Data obtained were subjected to one way analysis of variance. Serum biochemical indices and microbial load were not significantly (p>0.05) influenced by the treatments. A fraction of haematology, the haemoglobin (Hb) and eosinophil (Eos) were significantly (p<0.05) influenced by different stocking densities. Microbial toad, Utter moisture and temperature increased linearly with increasing stocking density across the treatments. Blood profile of the broiler chickens indicated no negative effect of stocking density except on Hb and Eos which reflected the packed condition of the birds. In conclusion, stocking density of 10birds/m2 can be recommended as birds fared best under this treatment.
