Abstract
Growth characteristics and meat quality in Japanese black somatic cell cloned cattle were investigated in 11 clone-derived animals, the original donor animal and nine conventional cattle. The coefficients of variation (CV) of growth characteristics for body weight, withers height and chest girth in the clones were lower than those of the conventional control animals. The CVs of carcass characteristics, including beef marbling standard number (BMS No.), in the clones were lower than those of the controls. The CVs of almost all physicochemical traits analyzed, except for collagen and muscle fiber, and sensory traits in the longissimus muscle, were lower in the clones than those of the controls. All growth characteristics were similar between clones and controls (P > 0.05). Although there were statistical differences between clones and controls in many meat qualities, there was no remarkable biological difference ; indeed, most differences were caused by alterations in intramuscular fat content as a result of genetic background. Furthermore, there is a possibility that mitochondrial DNA affected intramuscular fat deposition, although its effect might be slight. High similarities between clones and the original donor in growth and carcass characteristics were recognized. These results suggested that the similarity among the somatic cell clones in growth characteristics and meat quality was high, and that growth characteristics and meat quality derived from somatic cell clones were similar to those from in conventional cattle.
