사양환경이 제주산마(제주마×더러브렛)의 생리적 특성과 생산성 및 등심근 특성에 미치는 영향

This experiment was conducted to investigate the effects of individual management and group management of Jeju cross-bred horses on the physiological characteristics, productivity, and characteristics of the loin muscle of the horse meat. Sixteen herds of Jeju cross-bred horses older than 44 months were selected as experimental subjects. The experiment was conducted by dividing the herds into eight herds for individual management and another eight herds for group management. Herds were fed with concentrated feed of 2.5% of the body weight for four times a day and roughage and water were fed ad libitum. In the 12th week, the intestinal pH was statistically significantly lower with group management than with individual management (p<0.05). However, no symptoms of colic were observed. With regard to the general composition of the loin muscle, fat content was a statistically significant difference between the 7.83% with individual management and 5.65% with group management (p<0.05), indicating that individual management is more effective than group management in terms of fattening. In conclusion, feeding a concentrated feed at a level of 2.5% of body weight with individual management during fattening of Jeju cross-bred horses could be utilized as a fattening method.
