Two experiments with daily supplementation of from 1 g vitamin C pr. pig at 10-12 kg live weight, gradually increased to about 8 g at 100 kg live weight, are described. Experiment I consisted of 9 pigs supplemented with vitamin C on the food once a day, and 9 pigs used as control group. Experiment II consisted of 2 litters, each of 10 pigs. Five pigs from each litter were given vitamin C supplement intramuscularly once a week until 6 weeks of age, thereafter on the food once a day, and the other 5 were used as control group. Incidence and degree of lesions in the elbow joint, in the distal epiphyseal plate of ulna and in the medial condyle of femur were examined after slaughtering. There was no statistically significant difference in incidence or degree of lesions between the comparable groups. However, in experiment I there was a tendency toward less severity of lesions among pigs getting vitamin C (Table I). groups were slaughtered at the same age. The mean slaughter weight was 5.2 kg higher for the pigs which had gotten vitamin C. The difference was not statistically significant.
描述了两项实验,在猪体重10 - 12千克时,每头猪每日补充1克维生素C,到体重100千克时逐渐增加至约8克。实验I包括9头猪,每天在食物中补充一次维生素C,9头猪作为对照组。实验II包括2窝猪,每窝10头。每窝中的5头猪每周肌肉注射一次维生素C,直至6周龄,此后每天在食物中补充,另外5头作为对照组。屠宰后检查肘关节、尺骨远端骨骺板和股骨内侧髁的病变发生率和程度。可比组之间在病变发生率或程度上没有统计学上的显著差异。然而,在实验I中,补充维生素C的猪的病变严重程度有降低的趋势(表I)。各组在相同年龄屠宰。补充维生素C的猪的平均屠宰体重高5.2千克。差异无统计学意义。
