“…Previous studies in quail and chicken revealed that TM chicks had a larger relative breast muscle weight (4, 5, 7, and 19). These results are attributable to a higher percentage of larger diameter (hypertrophy) muscle fibers than the control group (7,19).…”

“…Adaptation for thermotolerance and breast muscle yield were enhanced without any significant alterations in the characteristics of breast meat quality (5). The intermittent embryonic TM of Japanese quail at ED 6 -8 improved final body weight at post-hatch day 35 which was manifested by significant breast muscle hypertrophy (6,7). The reduction of the abdominal fat pad relative weight is one of the goals of broiler management.…”

Embryonic thermal manipulation was known as an effective protocol for improving post-hatch growth performance and thermotolerance acquisition among avian species. Previously, we evaluated the impact of embryonic thermal manipulation of Japanese quail on embryonic development, hatchability, and post-hatch performance. We conducted the current study to furtherly elucidate the effects of thermal manipulations of Japanese quail embryos on internal organ weights, carcass traits, and meat quality parameters at post-hatch day 35. Quail eggs of control group were incubated at 37.7 °C and relative humidity (RH) 55%. Three thermally manipulated groups of quail eggs were incubated intermittently at 41°C and 65% RH intermittently (3 hours/day): the early embryonic group (TM1) was thermally challenged at embryonic day (ED6) to ED8, the late embryonic group (TM2) was thermally challenged at ED12-14, and early/late embryonic group (TM3) was thermally challenged in both time windows. Quail meat quality parameters, carcass traits, and internal organ weights were evaluated at post-hatch day 35. The results revealed that early embryonic thermal manipulation (TM1 group) is an effective protocol for decreasing fat pad accumulation. The pH value of breast meat in all TM treatments revealed significant (P < 0.05) decreases by 5% in comparison with that of control without any negative effects on breast meat composition or sensory criteria. Early embryonic thermal manipulation would be recommended as an enhanced protocol that can be used to reach the favored lucrative effects of the thermal treatment in meat-type quail.

“…The poultry industry wants fast-growing and uniform broilers (Bryant et al, 2021). However, the chick quality and hatchability are affected by some factors, such as broiler breeder age (Damaziak et al, 2021b), egg size (Luquetti et al, 2004), length of time eggs are stored (Tesarova et al, 2021), temperature (El-Shater et al, 2021), humidity (Abioja et al, 2021), controlled atmosphere (Damaziak et al, 2021a), and the orientation and position of the eggs (Ozlu et al, 2021b). There is a complex relationship between these factors.…”

An experiment was conducted to assess how hatchability performance of eggs is affected by line and age of female broiler breeders. Response variables analyzed were hatchability, infertility, pipping (i.e., pipped shell but not emerged), embryonic mortality (1st, 2nd, and 3rd wk), and embryonic malposition. The trials involved a total of 2,880 fertile eggs from two broiler breeder lines (Ross 308 and Cobb 500) at two different ages (30 and 50 wk). A 2 x 2 factorial design was used, where the broiler breeder line and broiler breeder age were the main effects. The hatchability in the Ross 308 line was higher than the Cobb 500 line, but its infertility was higher than the Ross 308 line. Hatchability in interaction (50 wk age of the hen in the Cobb 500 line) was less, and their infertility was higher. Embryonic mortality, pipping, and embryonic malposition did not present differences for the interaction between factors. The results suggest that hatchability performance of eggs can be improved, if egg management and incubation procedures are adjusted to account for the interaction between broiler breeder line and broiler breeder age.
