The aim of this research was to investigate the anatomical location of muscles and their meat quality traits, including muscle pH, water-holding capacity, meat color, tenderness, and sarcomere length, of Korean native black goat(KNBG). Five male KNBGs of 18 months of age were slaughtered and four major muscles-longissimus dorsi(LD), psoas major(PM), semimembranosus (SM), and gluteus medius(GM)-were sampled to determine proximate analysis and meat quality traits. There were no significant(p>0.05) differences in chemical components among the four muscles. The water-holding capacity(WHC) of the four muscles was significantly(p<0.05) affected by muscle type, although the pHu and meat color were not significantly(p>0.05) different among the four muscles. The Warner-Bratzler shear force of PM(4.07 kg/㎠) was significantly(p<0.05) lower than that of SM(5.57 kg/㎠) muscle. In addition, the sarcomere length of PM(1.99 ㎛) was significantly(p<0.05) longer than that of SM(1.72 ㎛) and LD (1.76 ㎛). Results suggest that the lower shear force of PM muscle is due to its longer sarcomere length.

The objective of this experiment was to investigate amino acids and mineral compositions of the four major muscles (LD: longissimus dorsi, PM: psoas major, SM: semimembranosus, and GM: gluteus medius) from Korean native black goat (KNBG). Five uncastrated male KNBGs of 36 months of age were commercially slaughtered and the four muscles were sampled to determine concentrations of myoglobin, collagen, amino acids and minerals. There were significant differences (p<0.05) in myoglobin and collagen content among the four muscles. Myoglobin content of PM was significantly higher (p<0.05) than those of SM and GM. Collagen content of SM was significantly higher (p<0.05) than that of LD. There were significant differences (p<0.05) in cystine and leucine concentrations among the four muscles, and PM had the highest concentrations of the two amino acids compared to other muscles (p<0.05). Also, there were significant differences (p<0.05) in K, P, Mg and Fe contents among the four muscles from KNBG. PM had the highest mineral content while the lowest mineral content was observed in LD. In addition, Fe contents of PM and GM were higher than those of LD and SM (p<0.05). These results indicated that amino acids and mineral content vary considerably with the anatomical location of muscles of Korean native black goat.
