1. Two environmentally-controlled houses, one at a constant 21°C (low temperature), the other diurnally cycling at 21 to 30°C (high temperature) and two diets of 13.0 MJ ME/kg (low energy, LE) and 13.8 MJ ME/kg (high energy, HE) were used to study the effects of age and sex on broiler carcase portions, dissected tissue proportions, and meat quality. 2. Slaughtering at 54 d instead of 34 d produced broilers with breast and leg weights of 277 and 308 instead of 284 and 319 g/kg carcase respectively, and a higher cutting loss (31 versus 6 g/kg carcass). 3. Males had lower proportions of breast, breast meat and fat, but higher proportions of leg, leg bone, and total meat to fat ratio than females. 4. Cycling high temperature resulted in higher breast, and lower leg proportions than constant low temperature. 5. High dietary energy content increased cutting loss, proportion of breast fat and lowered meat to fat ratio when compared to low energy, but did not affect the flavour of the meat, which was improved by age and high environmental temperature.
(nemacki) Zusammenfassung: In einem Vergleich mit Perlh?hnern, Fasanen und Broilern wurden die Merkmale des Schlachtk?rpers und der Fleischqualit?t miteinander verglichen (n = 190). In Abh?ngigkeit des Produktionsverfahrens sind die Lebendgewichte, Schlachtgewichte und deren Anteile des Schlachtk?rpers unterschiedlich. Die h?chste Fleischmenge ergaben die Fasane gefolgt von Perlh?hnern und Broilern. Die beste sensorische Bewertung erreichten die Broiler. Die Fasane hatten im Brustfleisch den h?chsten Protein- und den niedrigsten Fettgehalt. Das Fetts?uremuster unterlag dem Einfluss der Tierart.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
