Effect of growth-promoting technologies on Longissimus lumborum muscle fiber morphometrics, collagen solubility, and cooked meat tenderness.
The objective of the study was to examine the effect of growth-promoting technologies (GP) on Longissimus lumborum steak tenderness, muscle fiber cross-sectional area (CSA), and collagen solubility. Crossbred feedlot heifers ( = 33; initial BW 464 ± 6 kg) were blocked by BW and assigned to 1 of 3 treatments: no GP (CON; = 11); implant, no zilpaterol hydrochloride (IMP; = 11); implant and zilpat...
متن کاملMeat tenderness and muscle growth: is there any relationship?
Our objectives for this manuscript are to review the mechanisms of muscle growth, the biological basis of meat tenderness, and the relationship between these two processes. Muscle growth is determined by hyperplasia and hypertrophy. Muscle cell size is determined by the balance between the amount of muscle protein synthesized and the amount of muscle protein degraded. Current evidence suggests ...
متن کاملAntioxidative, Antihyperlipidemic, and Growth-Promoting Effects of Kelussia odoratissima in Meat-type Chickens
Due to the presence of polyphenols and phthalides in Kelussia odoratissima Mozzaf (Umbelliferae; K. odoratissima hereafter), this medicinal plant might be a robust in-feed additive to modulate lipid peroxidation in meat-type chickens. The present study evaluates antioxidative, antihyperlipidemic, and growth-promoting effects of K. odoratissima in meat-type chickens. In a 37-day trial (5-42 days...

Crossbred feedlot heifers (n = 33; initial BW 464 ± 6 kg) were blocked by BW and assigned to 1 of 3 treatments: no GP (CON; n = 11); implant, no zilpaterol hydrochloride (IMP; n = 11); implant and z...
متن کاملResponse time of broiler chickens to cimaterol: meat tenderness, muscle composition fiber size, and carcass characteristics.
The response time to cimaterol (CIM), a beta-adrenergic agonist, by broiler chickens for carcass characteristics, muscle composition, muscle fiber size, catheptic enzyme activity, and tenderness was determined. Two trials were conducted in which chickens were fed a control diet (CON) containing 0 ppm of CIM or a diet containing 1 ppm of CIM. Trial 1 consisted of 55, 31-d-old broiler chickens in...
