摘要: Abstract Seven selected muscles of 96 indigenous Nigeria (32 female, 32 castrated male and intact male) pigs aged between birth 504 days were analysed for chemical fat. Highly significant age effects observed the seven muscles. Statistically sex differences all except semitendinosus . Generally, fat values lower than other two sexes. While non-significant sex-age interactions biceps femoris, semitendinosus, semimembranosous longissimus dorsi muscles, highly psoas major, triceps brachii infraspinatus Growth coefficients b derived from log-log regressions intramuscular weight on body ranged an average 1·088 ( R 2 = 0·956) M. to 1·348 0·934) femoris 0·604 0·945) 0·756 0·941) when related carcass Average growth fore limb less hind spinal column Fat in depots is reported comparison with
