Muscle Growth and Poultry Meat Quality Issues
Over the past 50 years the worldwide growing demand of poultry meat has resulted in pressure on breeders, nutritionists and growers to increase the growth rate of birds, feed efficiency, size of breast muscle and reduction in abdominal fatness. Moreover, the shift toward further processed products has emphasized the necessity for higher standards in poultry meat to improve sensory characteristi...
متن کاملRelationship between muscle growth and poultry meat quality.
For a number of years, poultry selection has concentrated on growth velocity in meat lines, producing improvements in growth that have not been without consequence for muscle structure, metabolism, and meat quality. Higher growth rates may induce morphological abnormalities, induce larger fiber diameters and a higher proportion of glycolytic fibers, and a lower proteolytic potential in the musc...
متن کاملMeat Science and Muscle Biology: Beef Quality
The aim of this study was to establish the feeding duration and dietary level of vitamin E offered to young bulls which does not affect performance but positively improve shelf-life of beef. Three experiments were carried out: E1) 1,000 IU vitamin E/animal per d fed during 37, 49, and 63 d; E2) 2,000 IU vitamin E/animal per d fed for 77 d and E3) 3,000 IU vitamin E/animal per d fed for 55 d. In...
متن کاملPost-mortem Muscle Metabolism and Meat Quality
PSE, DCB and DFD meat are stress-related conditions. PSE meat occurs in pigs and turkeys. In pigs it is common in particular breeds which are known as stress-sensitive (SS) or halothane-positive (nn) genotypes. This chapter focuses on some of the key features in post-mortem muscle metabolism which lead to these meat quality problems, and so helps to explain how preslaughter stress influences me...
متن کاملMeat Science and Muscle Biology Symposium: extracellular matrix in skeletal muscle development and meat quality.
For decades, research in muscle biology has been focused on enlarging skeletal muscle mass, which increases the quantity of meat production. It has been well established that myogenic cells are derived from multipotent mesenychmal stem cells (MSC). During the embryonic and fetal stages, muscle fibers are formed through the fusion of myogenic cells; enhancing the proliferation and myogenic diffe...
