| Abstract: The objective of this work was to evaluate the inclusion of sunflower cake (SC) and the addition of enzymes in the ration of lightweight replacement pullets in the growth phase, as well as their effects on the variables feed consumption and conversion, productive performance, sexual maturity, egg quality at the beginning of the laying phase, and economic viability. Five hundred and forty pullets of the Hy-Line W-36 light line were used. The experimental design was completely randomized, in a 2×2+1 factorial arrangement, with two inclusion levels of SC (10 and 20%), with or without the addition of enzymes, and a control treatment. At the end of the growth phase (7 to 17 weeks age), 360 birds were transferred to the laying shed until their... |

| ABSTRACT With this study we aimed to evaluate and compare physicochemical and microbiological characteristics of frozen and chilled chicken meat. Only the prime cuts (breast, thighs, and drumsticks) were considered for the analysis of chemical composition, pH, color, water-holding capacity (WHC), thawing-cooking loss (TCL), and shear force (SF). For microbiological analysis, mesophilic bacteria, thermotolerant coliforms, and Salmonella spp. were considered. The frozen and chilled chicken meat showed no PSE (pale, soft, and exudative) or DFD (dark, firm, and dry) type of anomalies. The chromaticity showed higher redness in the breast (a* = 0.23) and yellowness in the thigh (b* = 5.64) for the frozen meat. The chilled meat showed better values for... |
