This study configures a first report regarding the variability of meat quality of locally adapted Pantaneiro sheep depending on different physiological stages and breeding systems. Pantaneiro sheep are raised in Brazil under a tropical wetland ecosystem denominated Pantanal. Twenty-nine Pantaneiro sheep from different sex and physiological stages were sorted into three groups, simulating three ...

Steaks from USDA Select inside rounds (Exp. 1) and shoulder clods (Exp. 2) were used to test the interactive effect of cookery method and endpoint temperature on Warner-Bratzler shear force (WBSF) and internal cooked color. Pairs of 2.5-cm-thick semimembranosus (SM) or infraspinatus (INF) steaks ( = 360/muscle) were cut from each subprimal, labeled, vacuum packaged, and frozen at -30°C in the d...

Three experiments were conducted to determine whether feeding 25-hydroxyvitamin D3 (25OH D3) or 1,25-dihydroxyvitamin D3 (1,25-(OH)2 D3) improves the tenderness of longissimus dorsi (LD), semimembranosus (SM), and infraspinatus (IF) muscles similar to supplemental vitamin D3 without leaving residual vitamin D3 and its metabolites in muscle. In the first two experiments, 24 crossbred steers were...

2255-4971 On March 1, Prof. Dr. Eduardo Álvaro Vieira passed away. n 1971, he was the first orthopedics and traumatology resient of the Sorocaba Medical School of the Pontifical Catholic niversity of São Paulo (PUC-SP), of which he became a proessor in the same year. He was a pupil of Professor Luiz ustavo Wertheimer, became interested in knee surgery and onducted extensive anatomical studies o...

Distal myopathies are a clinically and genetically heterogenous group of disorders in which the distal limb musculature is selectively or disproportionately affected. Precisely defining specific categories is a challenge because of overlapping clinical phenotypes, making it difficult to decide which of the many known causative genes to screen in individual cases. In this study we define the dis...

The impact of selecting for lean meat yield using breeding values for increased eye muscle depth (PEMD) and decreased fat depth (PFAT) on the consumer acceptance of lamb meat was evaluated. Consumer sensory scores (tenderness, juiciness, flavour, odour, overall liking) were obtained for the longissimus lumborum (loin) and semimembranosus (topside) muscles of 1471 lambs. On average loin samples ...

Knowledge of the anatomical organization of the hamstring muscles is necessary to understand their functions, and to assist in the development of accurate clinical and biomechanical models. The hamstring muscles were examined by dissection in six embalmed human lower limbs with the purpose of clarifying their gross morphology. In addition to obtaining evidence for or against anatomical partitio...

Abstract To investigate the effects of maternal nutritional plane and selenium (Se) level on offspring muscle development in first parity ewes, Rambouillet ewes (n = 84) were stratified by BW randomized to receive diets formulated contain adequate Se (ASe) or high (HSe) initiated at breeding. On d 40 gestation, assigned randomly within treatments supply 60% (RES), 100% (CON), 140% (HI) NRC requ...

Pen housing has been proposed in rabbits as an alternative to standard-sized cages. Rabbits reared in pens show greater physical activity. This study investigated whether jump exercise could modify body composition, muscle biochemical and histological characteristics, and some meat quality traits, including the biomechanical properties of tendons. Male weaned rabbits of similar BW (793 +/- 11 g...
