초록

본 연구는 농후사료의 급여 횟수에 따른 제주산마의 체중 변화 및 산통에 미치는 효과를 구명하기 위하여 수행되었다. 공시축으로 36개월 내외의 제주산마를 공시하였으며, 농후사료를 체중의 2.5%로 2회, 3회, 4회로 급여한 후 체중 변화 및 생리적 변화와 혈액 특성을 조사하였다. 총 증체량은 농후사료 일일 2회 급여구에서 55.80kg, 3회 급여구에서 54.40kg, 4회 급여구에서 63.00kg을 나타내 유의적인 차이는 없었다(p>0.05). 일당 증체량은 농후사료 일일 2회, 3회, 4회 급여구에서 각각 0.69kg, 0.67kg, 0.78kg을 나타내어 일일 2, 3회 급여구보다 4회 급여구에서 일일 증체량이 높은 경향을 나타냈으나 유의적인 차이는 없었다(p>0.05). 모든 처리구에서 직장 온도는 정상 범위보다 높은 경향을 보였고, 분 pH는 정상 범위보다 낮았으나 12주차에 모든 처리구에서 6.0보다 높아지는 경향을 보였다. 모든 처리구에서 높은 직장 온도와 낮은 분 pH를 보였지만 산통 증상은 나타나지 않았는데 이는 품종에 따른 차이에 의한 것으로 사료된다. 산통 지표로 알려진 피브리노겐과 질병 발생의 지표로 알려진 백혈구는 정상 범위 내에 있었고 시험 기간 동안 유의적인 차이를 나타내지 않았다(p>0.05). 결론적으로 제주산마에게 일반적인 농후사료 급여량보다 높은 양인 체중의 2.5%의 농후사료를 급여할 경우, 여러 번에 나누어 주는 것이 산통 발생 방지 및 소화에 도움이 될 것으로 가정했으나 급여 횟수에 따른 증체량, 혈액, 생리적 특성의 차이는 나타나지는 않았다. 결론적으로 제주산마에게 체중의 2.5% 농후사료를 12주간 2회, 3회, 4회 급여하는 것에 따른 생산성 및 산통 발생에 차이가 없어 노동력의 투입을 감안했을 때 2회로 나누어 주는 것이 유리할 것으로 사료된다.

This study was conducted to investigate the effects of concentrate feeding frequency on weight change and the colic of Jeju cross-bred horses. Around thirty-six old Jeju cross-bred horses were divided into three groups and were investigated by feeding the concentrate feed at 2.5% of their body weight 2 times, 3 times, or 4 times daily. Although the total weight gain and daily weight gain for the different feeding frequencies were higher with feeding concentrates 4 times daily compared with the other treatment groups, there was no statistically significant difference between the groups (p>0.05). Rectal temperatures were above the normal range in weeks 11 to 12, but there was no statistically significant difference between the groups (p>0.05). Fecal pH was below the normal range in weeks 1 to 12, but there were no colic symptoms with any of the treatments and there was no statistically significant difference between the groups (p>0.05). When feeding concentrate feed at 2.5% of body weight, it was assumed that trying to feed it several times per day would help to prevent colic; however, there was no difference in weight gain, blood characteristics, and physiological characteristics in accordance with the number of feeding times.
