The experiment was conducted to determine the feeding value of Russian Comfrey (Symphtyum peregrenium) by growing pigs. Sixteen Berkshire gilts were alloted into 4 treatments according to the levels of Russian Comfrey (R.C.) in pig ration such as 0%, 10%, 20%, and 30% on air-dried basis. Body weight gain, feed efficiency, economical feeding value and palatability in each treatment were investigated. The experimental results obtained were as follows; 1) In weight gain the pigs fed 10% R.C. ration showed more gain (P$lt;0.05), but those fed 30% R.C. ration showed less gain (P$lt;0.05) than control group of pigs did. And the pigs fed 20% R.C. ration showed no more gain than the control pigs statistically. 2) Feed efficiency in 10% R.C. ration was also higher than that in any other rations. 3) Feed cost per ㎏. weight gain was lowest in 10% R.C. ration and slightly higher 30% R.C. ration than that in control ration. 4) From the feed intake it was considered that Russian Comfrey should be considerably palatable to pigs. And from the above results, it was estimated that Russian Comfrey could be supplemented by 20% in the pig ration successfully.
