Genetic selection has significantly improved the muscle development of fast-growing broiler chickens in the last 50 yr. However, improvement in muscle growth has coincided with relatively poor development of visceral systems, resulting in impaired ability to cope with high environmental temperatures. The aim of this study was to elucidate the effects of thermal manipulation (TM) during differen...

The study was conducted to evaluate the impact of feeding multistrain probiotic on breast muscle characteristics of avian pathogenic Escherichia coli (APEC) infected broilers. Three hundred and thirty six Lohmann MB-202 day-old-chicks were divided to four treatment groups, including CNTRL (chicks receiving basal diet and not infected), APEC (chicks receiving basal diet and infected with APEC), ...

The present study evaluated the carcass and meat quality traits of three groups Japanese quails. These {i.e. selected for 4-week body-weight group (WBS), egg number (EBS), random-bred control (RBC)}, were consecutive generations from a base population 1125 In total, 2700 four-week-old quails lines (225 birds per generation) slaughtered in total four (G0 to G3). effects selection on generations....

introduction poultry meat enriched with long-chain polyunsaturated fatty acids n-3 (pufa lc n-3) can make a nutritionally meaningful contribution to western diets in which consumption of pufa lc n-3 is low. enrichment of poultry meat with this fatty acid is usually achieved by inclusion of fish oil in broiler diet (23, 24). however, meat enriched in this way is susceptible to quality deteriorat...

This study analyzed the effects of salt reduction on microbiological composition and quality characteristics of deli-style turkey breast and roast beef. Turkey breast and roast beef were manufactured with salt concentrations of 1.0%, 1.5%, 2.0%, and 2.5% on a meat block basis in addition to sugar, phosphate, and water. Samples were cooked, chilled overnight, sliced, and packaged. On the day of ...

Carcass measurements and some immunocompetence parameters were investigated in naked neck (NaNa & Nana) and normally feathered (nana) genotypes under summer season conditions of Egypt. Two hundred and ten broiler chicks (70 of each genotype) were reared under similar environmental, managerial and hygienic conditions. The feed and water were provided ad libitum. The average high and low ambient ...

The influence of the season and market class of broiler chickens on breast meat quality traits was determined on a total of 18 flocks reared and processed under commercial conditions. According to the Italian poultry production system the following classes of birds were considered: light size (1.2 kg of carcass weight; n = 90) and medium size (1.8 kg of carcass weight; n = 90), represented by f...

Background: One of the concerns of consumers of animal protein sources is the residues of heavy metals in meat. The accumulation of these elements in meat and the consumption by humans can cause acute and chronic disorders in the function of vital organs. Methods: For the estimation of cadmium, zinc and silver in the poultry meat products, 100 samples of chicken breasts, thighs, hearts and liv...

The objective of this study was to establish the effects chestnut tannin extract or vitamin E added linseed oil-enriched diets on growth performance, meat quality, and intestinal morphology broiler chickens. A total 240 day-old Ross 308 male chicks were included in trial. 5% cold-pressed oil finisher (21–40 days), three feeding treatments with four replicates formed: without additives; + 200 IU...
