This study recommends effective ways to establish management strategies by suggesting to hog farm managers the importance of variables` tendency to affect MSY according to hog management. Study subjects included 55 hog farms, which were analyzed using factor and regression analyses to determine each variable`s importance (22 total) for hog management, using MSY as the dependent variable. In the analysis result, the main necessary factor controlling MSY improvement was vaccination, followed, according to decreasing significance, by stages of growth classified breeding, thermo-humidity and ventilation control, and veterinary and hygienic control. Based on these results, suggesting the main factors to improve MSY to hog farms will establish management strategies. |
