“…of heritability between walking ability classes across the four growth rate quartiles for the 0-12, 12-20, and 0-20-week periods using a multivariate threshold model showed non-negligible variation due mainly to changes in genetic variances across growth quartiles. However, heritability estimates (0.18-0.26) across growth quartiles and period are consistent with reported estimates in the literature [9,13,25]. Our estimates were higher than those reported by [14] for gait scores, tibial dyschondroplasia foot dermatitis, and valgus and varus deformities (0.03-0.15) but almost identical to heritability estimates for WA (0.18-25) obtained by Quinton et al [9].…”

The aim of this study was to investigate the potential non-linear relationship between growth and walking ability (WA). The phenotypic data included body weights at 12 and 20 weeks and WA at 20 weeks of age measured on 276,059 male turkeys. The growth rate at three age periods (0 to 12, 12 to 20 and 0 to 20 weeks) was calculated. Each bird was assigned to one of the quartiles of the growth rate distribution for each age period. Between the first and fourth quartiles, the incidence of score 1 (bad WA) increased by 31, 18, and 33% for the first, second, and third age periods, respectively. For good WA (scores 4, 5, and 6), the incidence decreased by 55, 66, and 72% between the first and fourth quartiles for the first, second, and third age periods, respectively. Estimates of heritability of WA ranged between 0.18 and 0.26. The genetic correlations between adjacent growth rate quartiles were high and decayed as the interval between quartiles increased. The magnitude of the variation in the incidence of walking scores and genetic correlations across the growth rate quartiles point towards a non-linear relationship between growth and mobility suggesting other factors may affect walking ability.

“…In breast muscles, a lower pH was accompanied by a lighter colour of muscles, while it was the opposite in thigh muscles. The pH values in the breast muscles measured during the study were not in good agreement with those of Hiscock et al [ 73 ]. By contrast, Owens et al [ 75 ] found a PSE defect in turkey meat with pH = 5.72 and a lightness exceeding 54%.…”

“…Meat quality can be described based on its physical and nutritional attributes. The physical properties can be determined by the genetic line and nutrition [ 10 , 72 , 73 ]. Yalcin et al [ 1 ] claimed that the selection for larger, faster-growing birds continues, and there has been a noticeable increase in meat quality defects.…”

In order to increase growth performance and carcass composition, including meat quality, as demanded by modern customers, alternative feed additives are sought after as a result of the withdrawal of antibiotics employed as growth promoters in poultry feeding. Therefore, we conducted a study to see how effective three feed additives added to the diets and water of turkey hens were. The experiment consisted of 200 Big 6 turkey hens divided into two equinumerous groups (C and E), with five subgroups in each. The 14-week-long growth performance study comprised five feeding periods. Both groups of birds were fed complete feed rations with mineral and vitamin supplements. The factor differentiating the groups were effective microorganisms and Humokarbowit added to the birds’ diets and garlic extract added to the drinking water in the experimental group (E) only. It was demonstrated that the included feed additives in the diets and water of turkey hens significantly increased (by 10%) the FBW and decreased (by 14%) the FCR throughout the rearing period. Birds from the E group scored significantly higher (by 3.6%) on the dressing percentage, and their muscularity and fattening grade were improved. Turkey fed rations containing the evaluated feed additives had a smaller share of the gastrointestinal tract in the body weight and a shorter duodenum and caecum (p ≤ 0.05). The muscles of turkey hens from group E featured a lower pH24 and were of lighter colour (p ≤ 0.05). To sum up, the use of effective microorganisms and Humokarbowit in the diets and garlic extract in the drinking water of turkey hens should be recommended in view of improved growth performance and carcass composition.

“…On the other hand, when fewer resources are available, the status of a native genotype can be approached through phenotypes, since phenotypic traits are a direct consequence of the genotype ( 24 ). This approach has been followed in studies comparing meat and carcass quality attributes between turkey breeds and varieties ( 4–8 , 13 , 30 , 31 ) and their crossbreeds ( 32–34 ).…”

“…Describing the correlation of traits is crucial to increasing the efficiency of resource allocation in the method since the reduction of measures is possible by selecting highly explanatory and correlated variables. Thus, correlations between the most common meat and carcass traits have been reported in several poultry species ( 4 , 36–38 ).…”

The present study aims to develop a statistical tool for turkey breed traceability testing based on meat and carcass quality characteristics. To this end, a comprehensive meta-analysis was performed, collecting data from a total of 75 studies approaching meat and carcass attributes of 37 turkey strains and landraces since the late 1960s. A total of 22 meat and carcass traits were considered variables, grouped in the following clusters: carcass dressing traits, muscle fiber properties, pH, colorimetry, water-capacity traits, texture-related attributes, and nutritional composition of the meat. Once the multicollinearity analysis allowed the deletion of redundant variables, cold carcass weight, slaughter weight, muscle fiber diameter, sex-female, carcass/piece weight, meat redness, ashes, pH24, meat lightness, moisture, fat, and water-holding capacity showed explanatory properties in the discriminating analysis (p < 0.05). In addition, strong positive and negative correlations were found among those variables studied. Carcass traits were positively associated, particularly slaughter weight and cold carcass weight (+0.561). Among meat physical traits, pH showed positive correlations with drip loss (+0.490) and pH24 (+0.327), and water-holding capacity was positively associated with cholesterol (+0.434) and negatively associated with collagen (−0.398). According to nutritional traits, fat and ash showed a strong correlation (+0.595), and both were negatively associated with moisture (−0.375 and −0.498, respectively). Strong negative correlations were found as well between meat protein and fat (−0.460) and between collagen and cholesterol (−0.654). Finally, the Mahalanobis distance suggested a clustering pattern based on meat and carcass characteristics that report information about interbreeding and variety proximity. This study establishes a departure point in the development of a tool for breed traceability guaranteeing aimed at enhancing distinguished, local breed-based turkey meat.
