Abstract
The study was conducted to find out the effect of age on carcass, meat quality
characteristics and nutritional composition of Nand anam Turkey-Il. Totally twelve birds were
separated into two different age groups viz., young (20 weeks) and adult (40 weeks). The
birds were slaughtered and breast muscle was obtained. The carcass, meat quality characters,
proximate composition, amino acid, fatty acid and cholesterol content of meat of two age
groups were analysed. The carcass characteristics viz., edible offal weight, in-edible offal,
blood weight, feather weight and head weight had significant difference (P<O.O 1) between two
age groups. Meat quality characteristics viz., pH (P<0.05), muscle fibre diameter (P<O.O 1) and
myofibrillar fragmentation index (P<O.O 1) of young turkey meat were significantly lower than
adult turkey meat. The young turkey meat had significantly higher moisture content (P<O.O 1),
while it showed significantly lower protein, fat and total ash content than adult turkey meat.
The significant difference (P<0.05) was observed in lysine and phenylalanine and highly
significant difference (P<O.OI) was observed in arginine, isoleucine, threonine, valine,
alanine, aspartic acid, glutamic acid and glycine contents of meat from young and adult age
groups of turkey. The meat of young turkey had significantly lower total saturated fatty acids
(P<0.01), mono unsaturated fatty acids (P<0.05) and higher poly unsaturated fatty acids
(P<O.OI), PIS ratio when compared to adult turkey meat. The cholesterol content of young
turkey meat was significantly (P<O.OI) lower than adult turkey meat. Based on the results
it was concluded that the meat of young Nandanam Turkey-Il had the superior meat quality
characters and nutritional composition than the meat of adult birds.
