| Se evaluó la actividad antioxidante (AA) de cuatro alimentos comerciales (1, 2, 3 y 4) en la actividad antioxidante y estabilidad oxidativa (EO) de lomo crudo (Longissimus dorsi) de conejos de tres genotipos (Nueva Zelanda, NZ, California, CAL y NZ*CAL) a tres tiempos de refrigeración (0, 3, y 6 días). La AA de todos los alimentos disminuyó a los 30 días de almacenamiento; sin embargo, el alimento 1 presentó mayor cantidad de antioxidantes (p<0.05). Con todos los genotipos y alimentos, la AA del lomo crudo disminuyó al día 6 de refrigeración. El genotipo NZ*CAL presentó mayor AA con el alimento 1 (p<0.05) y menor con el alimento 3 con respecto al genotipo NZ. Todos los genotipos presentaron un incremento de la oxidación lipídica a partir del día 3... |

| El uso de maíz para la producción de etanol genera grandes volúmenes de granos secos de destilería (DDGS: siglas en inglés), subproducto con destacado valor nutricional para la alimentación animal. Por ello, el objetivo del presente estudio fue evaluar el efecto de incluir DDGS en la dieta de corderos en crecimiento sobre el comportamiento productivo, variables ruminales (pH, AGV y N-NH3), degradabilidad in vitro de la MS (DIVMS), digestibilidad total aparente de la MS (DIAMS), FDN (DAFDN) y FDA (DAFDA), características de la canal y calidad de la carne. El diseño experimental fue completamente al azar usando 27 corderos criollos encastados con Rambouillet (PVI=24±2.41 kg), y los tratamientos fueron: 1) dieta testigo, sin DDGS; 2) con 20 % de DDGS y 3) con... |

| The MYF5 gene is first inducibly expressed in muscle cell during embryonic muscle development and plays an important role in regulating the differentiation of skeletal muscle precursors. In this study we used PCR-RFLP to investigate two pig (Sus scrofa) populations (n = 302) for two MYF5 gene polymorphisms, a previously unreported novel Met-Leu shift single nucleotide polymorphism (SNP) MYF5/Hsp92II located on exon 1 and the previously identified intron 1 MYF5/HinfI SNP. Haplotype and association analysis showed that haplotypes of the two SNPs were significantly associated with drip loss rate (DLR, p < 0.05), water holding capacity (WHC, p < 0.05), biceps femoris meat color value (MCV2, p < 0.05), biceps femoris marbling score (MM2, p < 0.01),... |

| The PSS genotypes of 596 F2 pigs produced by initial mating of Brazilian commercial sows and native boars were characterized by PCR-RFLP and the pork quality traits were evaluated. Among the 596 pigs studied, 493 (82.7%) were NN and 103 (17.3%) were Nn. There were no differences between NN and Nn pigs in the following pork qualities: pHu (5.71 ± 0.16 vs 5.70 ± 0.11), intramuscular fat (1.55 ± 0.64% vs 1.65 ± 0.67%), shear force (5552 ± 878 g/1.2 cm vs 5507 ± 826 g/1.2 cm), lightness (44.96 ± 2.05 vs 45.01 ± 1.92), redness (0.64 ± 0.60 vs 0.79 ± 0.55), yellowness (6.62 ± 0.56 vs 6.65 ± 0.48), hue (84.28 ± 5.53 vs 83.41 ± 4.85), or chroma (6.68 ± 0.52 vs 6.73 ± 0.52). However, pork from Nn pigs had a significantly (p < 0.05) lower pH45 (6.41 ± 0.27 vs... |

| The activity of the calpains/calpastatin proteolytic system is closely related to the postmortem tenderization of meat. We investigated the association between beef tenderness and single nucleotide polymorphism (SNP) markers on the CAPN1 gene (SNP316, alleles C/G; SNP530 alleles A/G) and the CAST gene 3' untranslated region (SNP2870, alleles A/G). We sampled nine slaughter groups comprising 313 steers which had been reared in beef production systems in Argentina between 2002 and 2004 from crosses between Angus, Hereford and Limousin cattle. Minor allele frequencies for the markers were 0.27 to 0.46 (C), 0.02 to 0.18 (A), and 0.24 to 0.53 (A), respectively. The presence of CAPN1 markers had significant effects on meat shear force but no detectable effects... |

| O termo qualidade é definido pela International Organization of Standardization (ISO) como: ?totalidade de aspectos e características de um produto que leve sua habilidade em satisfazer uma necessidade anunciada ou implícita??. Esta definição deixa evidente a relação existente entre a escolha e a satisfação, onde a primeira é a tentativa direta de alcance da segunda. A qualidade da carne suína engloba diferentes enfoques por parte das indústrias e dos consumidores. As indústrias utilizam como parâmetros a porcentagem de carne magra, rendimento de cortes, necessidade mínima de acabamento, aparência atrativa e alta estabilidade durante a estocagem a frio. Os consumidores, além do aspecto nutricional, percebem como relevantes os aspectos sensoriais, os quais... |

| Na produção de carne bovina são desejados modelos de sistemas que levam a uma menor idade ao abate e também a carcaças com mais atributos qualitativos desejáveis. Conhecido como novilho precoce, este modelo agrega ambas as qualidades e ainda é abrangente tanto para machos quanto para fêmeas e também quanto ao nível tecnológico necessário para sua execução. Do ponto de vista ambiental, possui características que se alinham a uma maior sustentabilidade. Por fim, observa-se o fortalecimento de iniciativas públicas e privadas de valorização do novilho precoce. Por todos estes aspectos, a Embrapa tem no novilho precoce uma referência de modelo produtivo e reconhece a importância de esforços de pesquisa, desenvolvimento e inovação para seu fomento. Assim, este... |

| The blue mussel, Mytilus edulis has been reared along the Normandy coast line since the 1960s. The gonadal cycle of this mussel species shows a sharp decrease in meat quality during the winter period after spawning. This decline in meat quality is so severe that sales have to be suspended from December to July. Another species of mussel, Mytilus galloprovincialis, which is reared in the lagoons along the French shore of the Mediterranean Sea has a different spawning cycle. An experiment was undertaken to study the meat quality of M. Galloprovincialis throughout the year after the spat were transferred from the Mediterranean Sea to the Normandy coast. This species showed an immediate adaptation to the gonadal cycle of M. edulis. Despite suggestions from... |

| Neuromuscular compartments are subvolumens supplied by a primary nerve branch with homogeneous fiber characteristics. This muscular organization is important for understanding the muscle function in relation to postural and dynamic implications and also is relevant for appraising meat quality. Current researches associate fiber muscle characteristics with perimortem processes that regulate muscle transformation into meat. It is known that pig muscle has four heavy chain myosin isoforms: I, IIa, IIx and IIb. Castrated male pigs were slaughtered at 100 kg live weight. Semitendinosus muscle samples of each subvolumen determined previously (R1, R2, R3, R4) were frozen in liquid nitrogen and reacted for myofibrillar ATPase and NADH-TR for determining fiber... |

| Abstract: The objective of this work was to analyze the effects of immunocastration on the performance and carcass quality of steers in the finishing phase, compared with non-castration and surgical castration. Data from ten studies with records of 1,261 male bovines were analyzed. The studies included in the meta-analysis necessarily contained treatments with immunocastration specifically against the gonadotropin-releasing hormone. Each study was considered as a random effect in the statistical model used. The data were tested for homogeneity of variances and residue normality, and then subjected to the analysis of variance. Means were compared by Student’s t-test. Non-castrated steers showed greater daily weight gain, feed efficiency, slaughter and hot... |
