다국어 초록 (Multilingual Abstract)

These experiments were carried out to determine the effect of liberal feeding of rabbit feces and residual forage on the growth, feed efficiency, feed cost and health of weaned pigs. The same litter pigs used were alloted into 3 pigs in the control and 3 pigs in the experimental in the trial I and 2 pigs in the control and 3 pigs in each of 3 experimental feeding groups in the trial II. All the weaned pigs were equally raised for 7 weeks of period. The results obtained were summarized as follows; 1. The liberal feeding of rabbit feces and residual forage resulted in slightly but not significantly more average daily gain (0.39㎏) of pigs during the experimental period. 2. The liberal feeding of rabbit feces and residual forage resulted in slightly more feed consumption but decreased the feed consumption and cost for 1 ㎏ of body gain to 3.10 ㎏ and 298 won, respectively. The decrease in feed cost for 1 ㎏ of body gain from the liberal feeding of rabbit feces and residual forage was estimated to be 52 won. 3. Rabbit feces and residual forage seemed to contained considerably much crude protein of 13.3% and 20.1% due to the urea of rabbit urine on the air-dry basis, respectively, and their excess in crude fiber and crude ash with low content in nitrogen free extracts was considered to be undesirable as a pig`s feed source. 4. The rabbit feces and residual forage had considerably high palatability to pigs and they were found to have no factors against pig`s health clinically. 5. The urea N concentration in blood plasma of control pigs (18.01㎎/100㎖) was similar to that of pigs fed rabbit feces but was lower than that of pigs fed residual forage (30.11㎎/100㎖) or rabbit feces and residual forage (22.75㎎/100㎖).
