Field efficacy of enterotoxigenic Escherichia coli-specific phage (ΦCJ19) as a feed additive was evaluated in weaning piglets. Fifty-four piglets at 3~4 weeks old were allocated in three different groups and two of them were fed with bacteriophage at different concentrations (106 PFU/kg feed and 108 PFU/kg feed, respectively) for 30 days. Body weight and feed intake were measured at 10 days interval and body condition and fecal score were inspected every day. Based on the measurement, feed conversion rate (FCR) and average daily gain (ADG) of each group during 30 days were analyzed. The analysis suggests that the bacteriophage may help the improvement of FCR and ADG at 108 PFU/kg of bacteriophage feeding group in 30 days. A result from analysis of fecal score indicates that the bacteriophage also may help to relieve the intermittent diarrhea in post-weaning stage. Those results suggest that bacteriophage might help the growth of piglets in post-weaning stage.

This study was attempted to verify the mechanisms of RBC survival time shortened with vitamin E deficient and decrement of phospholipid concentrations by administration of iron. The concentration of iron in basal ration (group A and group B) was 40 mg/kg of feed, and the final concentrations of iron in the Fe (OH)3 supplemented-rations (group C and group D) were 13,496 mg/kg and 26,973 mg/kg, respectively
