“…Variation among chicken breeds due to muscle fiber is largely associated with selection. Findings of the present study correspond with the study of Devatkal et al [12], who found variation in carcass traits among different meat-type chickens. Higher slaughter weight was observed for white broiler and the lowest for Aseel.…”

Introduction Genetic improvement in rural poultry can be accomplished by selection or crossbreeding while selection procedures are long-term but definite. Crossbreeding of indigenous germplasm with exotic breeds gives an advantage for artificial selection for performance of exotic breeds and natural selection for resistance and acclimatization of indigenous breeds for the local environment [1]. Crossbreeding results in the development of birds that have better growth, morphometric, and carcass characteristics and reproductive traits, hence reducing the total cost of production [2,3]. Birds under free-range housing systems have access to enriched environments that promote behavioral activities, i.e. scratching and foraging, and improve the overall welfare of the birds. Environmental enrichment can stimulate and encourage explorative behaviors and create a series of behavioral opportunities [4]. The benefits of such enrichments are numerous and give an opportunity to birds for more even distribution, which reduces aggression, stress, and fear response [5]. Such types of housing systems coupled with higher welfare standards can produced a better quality of poultry meat that is more suitable for consumer preferences in Europe, America, and Asia [4,6]. Meat quality attributes of organic and free-range housed chickens are considered more valued as far as quality is concerned. There are numerous factors that affect the quality of meat, such as genotype, nutrition, housing system, slaughter age, and motor activity [7-9]. Indigenous chicken breeds are generally nominated for free-range housing systems because of their hardy nature and better acclimatization in extreme weather conditions. Moreover, some studies reported that under intensive housing systems birds are unable to exploit their maximum genetic potential and their growth is limited because of deficient nutrition [10,11].

“…The quality of meat is a complex trait affected by genetic and nongenetic factors, and the variation in meat quality within and between birds can be wide [12]. Therefore, alternative housing systems and genotypes need to be further investigated.…”

“…Feeding of commercial diet was found to significantly improve live weight and dressing per centage in FNC as compared to BNC. Similar to the findings of the present study higher weight and dressing per cent has been recorded by Poltowicz and Doktor (2012) in hybrid birds, Haunshi et al (2013) in Aseel and Kadaknath birds, Patel et al (2014) in Gramapriya birds reared under backyard system and Devatkal et al (2018) in Aseel. Dressing per centage is related to the age of the bird and as age advances there is considerable reduction in dressing per centage due to shrinkage of muscle.…”

Background: The commercial rearing of native chicken has been gaining importance due to higher demand for natural and organic meat. In this context the present study was designed to compare the carcass and meat quality characteristics of native chicken reared under backyard system as compared to native chicken reared under farm setting in Karnataka.Methods: Sixty (30 backyard and 30 farm reared) native birds were used to evaluate the carcass characteristics viz., dressing per cent, yield of cut up parts and meat bone ratio. Breast muscle was used to evaluate physico-chemical (pH, WHC, colour, drip loss and cooking loss), compositional (proximate composition, cholesterol content and collagen content), structural characteristics (muscle fibre diameter, sarcomere length, shear force) and sensory characteristics.Result: A significant difference (P less than 0.05) in live weight, carcass weight and dressing per centage was evident in backyard native chicken (BNC) and farm reared native chicken with higher weight being recorded in FNC, whereas no significance could be observed in yield of various primal cuts between them. Physico-chemical and compositional characteristics revealed no significant difference, whereas farm reared birds had lower shear force and collagen compared to backyard birds. Sensory evaluation revealed no negative influence on any of the eating quality indicating that commercial rearing of native chicken could be advocated for faster growth of native birds without compromising on the quality of meat.

“…The drip loss was calculated as (weight initial –weight 24 h )/weight initial × 100%. The shear force of the breast muscle and thigh muscle was measured ( Devatkal et al., 2018 ) using a Texture Analyzer (TA.XTPlus; Stable Micro System, England).…”

Maternal dietary methionine supplementation influences egg production and the growth performance and meat quality of the offspring

et al. 2020

This study aimed to investigate the effects of maternal dietary coated methionine ( Met ) on egg production and the quality, growth performance, carcass traits, and meat quality of the offspring. In total, 288 female Ross parental chickens were randomly assigned to 3 groups with 3 replicates of 32 chickens each. From week 37 to 46, the hens of different groups were fed diets containing low (0.27% Met), adequate (0.27% Met + 0.1% coated Met) ( AM ), and high (0.27% Met + 0.2% coated Met) ( HM ) Met. There was a positive response in laying rate and albumen weight in AM and HM groups. For the offspring at market age, BW, eviscerated weight, and muscle weight were increased in the AM group ( P < 0.05), whereas excessive supplementation was proven to be negative with those traits. The meat quality (color, pH, and shear force) of breast muscle was significantly influenced by different supplementation levels. The lightness and yellowness were increased in the HM group ( P < 0.05, P < 0.01, respectively), and redness was decreased in the AM group ( P < 0.05). A lower pH value occurred in chickens of the HM group ( P < 0.05). The expressions of meat quality–related genes were altered in the supplementation groups. The pH-related genes PRDX4 and PRKAG2 were found to be significantly differentially expressed ( P < 0.05, P < 0.01, respectively) and consistent with pH changes. The meat color–related gene BCO1 was also differentially expressed ( P < 0.01) and showed a corresponding change with yellowness value. Collectively, the best production performance was in the offspring with 0.1% coated Met supplementation (AM group). Supplementation with 0.2% coated Met (HM group) seemed to be excessive, but laying rate was increased in the HM group. Both results of phenotypic measurements and gene expression demonstrated that maternal-coated Met supplementation resulted in fluctuation of some meat quality indices in the offspring, but all values were still within the range found in normal chickens.
