“…Although free range was available to slow-growing strains, their growth rate was not comparable with Cobb-500. Similar findings were reported in a study in which intensively reared Harco black genotype had higher morphological lengths of tibia than free-range Novogen strains (Sogunle et al, 2012). Contrary to the current findings, Akşit et al (2017) reported no effect of environmental enrichment on tibia length.…”

The behaviour, welfare, and tibia characteristics of fast- and slow-growing chickens were evaluated in free-range and intensive production systems. A total of 720 birds of three strains were subjected to these systems after 21 days of rearing under the same intensive environment. Each treatment was replicated six times with 20 birds in each replicate. Data were collected for welfare aspects, including feather condition, footpad, hock joint and tonic immobility, behavioural features, especially feeding or foraging, sitting, walking, scratching, pecking and dust-bathing, and tibia characteristics, including weight, length, width, medullary canal diameter and robusticity index (4 - 8 weeks). Production system had significant effects on all welfare and behaviour aspects of the birds. However, tibia characteristics were not influenced by production system, except for medullary canal diameter. The strains differed significantly in welfare, tibia characteristics and behaviour. For example, the slow-growing strains had better feather condition, footpad and hock joint scores. Significant interactions of strain and production system were noted for all characteristics. It was recommended that Rhode Island Red chickens could be raised under either production system without compromising their welfare or causing adverse effects on leg health.

The present investigation was carried out for comparing the carcass and meat quality attributes of improved chicken variety ie) rajasri male chicken and broilers meat to assess the extent of suitability for preparing the processed/value added chicken meat products. Rajasri chicken recorded significantly (P<0.05) lower pre slaughter weight, dressing per cent, giblet yeild and cut up parts yield compare to broilers. Broilers meat recorded significantly (P<0.05) lower drip loss, pH, muscle fibre diameter, collagen content, cooking loss, total protein and total fat content and significantly (P<0.05) higher waterholding capacity, total protein extractability and collagen solubility than rajasri chicken meat. Broiler meat recorded significantly (P<0.05) superior sensory scores compared to rajasri chicken meat. From these results, it can be concluded that rajasri meat is lower carcass and meat quality attributes compared to broiler meat but this can also be utilized for preparation of processed and value added chicken meat products without adverse affect on quality of finished processed meat product.

“…The variation in the amount of certain tissue will influence the proportion of other tissues and, in situations of similar weight, birds with a higher amount of muscle tissue will indicate individuals with a higher potential for growth and meat production (SOGUNLE et al, 2013). This was also observed for females that presented a higher proportion of meat and a lower proportion of bone in the legs (Table 3).…”

This study aimed to assess the effect of different breeds and crosses of broiler chickens and sex on growth, carcass characteristics, and tissue composition. The experimental design was a completely randomized design in a 6 × 2 factorial scheme, with six genotypes (New Hampshire – NHS, Jersey Black Giant – JBG, Rodhe Island Red – RIR, Indigenous Giant – IG, and the hybrids IG × NHS and IG × JBG) and two sexes (male and female). Each treatment was composed of five replications with three broiler chickens, totaling 180 broiler chickens. Zootechnical performance and growth were assessed through the Gompertz equation parameters. After slaughtering at 105 days, the characteristics of carcass and main cuts were determined by means of weight, yield, and proportion of tissue constituents (meat, bone, and skin). Regarding the Gompertz equation parameters, the genotype NHS presented a higher growth potential. Males presented higher live weight and carcass weights, except for IG. No difference was observed between genotypes and sexes (P > 0.05) for carcass yield. The genotype JBG presented the highest average for breast yield (24.4%). Males presented the highest average for leg yield (30.5%). The genotype IG presented the highest value of breast meat yield (71.2%), being similar to the genotypes from the crosses IG × NHS, and IG × JBG (68.9 and 68.3%, respectively). For meat to breastbone ratio, the genotype IG presented the highest value (3.4) and, considering the sex, females presented a higher average (3.2) for this characteristic. Regarding the proportion of leg meat, an effect was observed for genotype and sex (P < 0.05) with the highest values observed for the hybrid IG × JBG and females (66.3 and 66.0%, respectively). For meat to leg bone ratio, the genotypes NHS, JBG, RIR, and IG × NHS presented the highest values (2.6, 2.7, 2.6, and 2.6, respectively), with females presenting the highest value (P < 0.05) (2.7). The genotypes IG, IG × NHS and IG × JBG presented the best growth and carcass characteristics, being recommended to be reared under an alternative system. Females presented the highest breast yield and, proportionally, the highest amount of leg meat, which are important attributes in a chicken meat production system.
