다국어 초록 (Multilingual Abstract)

This experiment was conducted to observe the effect of 3-vitro-4-hydroxyphenylarsonic acid on the growth rate and feed efficiency of broilers. For the experiment, 540 baby chicks of Indian River broiler type were raised for the period of 7 weeks in three different groups. The results obtained are summarized as follows; 1. The levels of adding 3-vitro-4-hydroxyphenylarsonic acid in the diet were not effective for the growth stimulation, but improved the feed efficiency. Symptoms of toxicity resulting from dietary arsenical were not found. 2. For the feed efficiency, there was highly significant difference between 0.009% 3-vitro-fed group and two other groups of 0% and 0.005%. Although no difference was recognized between 0.005% 3-vitro-fed group and the control, 0.005% group resulted in a slight improvement in comparison to the control. 3. The feed cost required for 1㎏ gain was the cheapest for 0.009% 3-nitro-fed group. There was little difference observed between 0.005% and the control groups. 4. Another attempt should be made for further evidence of the effect of an arsenical on the body gain which was not improved in this experiment.
