다국어 초록 (Multilingual Abstract)

This is the second step report of the three years plan on the development of sheep range in the Mt.Chiri. To investigate the effect of the native grasses in the Mt. Chiri on the growth rate, wool production and economical value of sheep this experiment was carried out for 288 days from June, 29,1970 to April,19,1971. Numbers of experimental animal used in this experiment was 12.
The results obtained here were as follows;
1. The sheep used in this experiment obtained approximately 17.0 to 23.2 ㎏. of body weight. However, there was no great difference among each experimental animal in the body gain.
2. 2 to 2.6 ㎏. of diet was consumed a day at the grazing period and 1.4 to 1.5 ㎏. of diet at the housing period.
3. 1.7 to 2.3 ㎏. of wool was produced by a sheep.
4. Health condition of sheep for trial period was largely good. However, 3 of experimental animal was infected with Lumbar Paralysis and 2 was recovered from Lumbar Paralysis by spatonin injection and 1 was died of However, it was difficult for infectious location to assert to infected animal because experimental animal was transport from the livestock experimental station, Goryong J1-branch at Dae Gwan Fyong in June.
5. Approximately 30 kinds of native grasses and legumes can used for ration of sheep.
6. In the chemical composition of native grasses, Dry matter of grasses was approximately contented 90 %. and content of crude protein was 5 to 17 %. Content of crude fiber was 24 to 40 %, and crude fat contented 1 to 2 %, crude 2 %, crude ash contented 4 to 7 %, and that of NFE was 40 to 80 %.
7. 1,645 to 3,331 Won of net income be able to get per sheep for throughout experimental period.
According to above results, it was found that it is most profitable for use of feed resources of native grasses speading 5,400 ha. area in the Mt. Chiri to rear sheep. On the other hand, to improve the growth rate, wool production and economical value of sheep by feeding of native grasses in the Mt. Chiri, it must considered problems such as grass improvement, moderate cutting of native grass, supplement of deficient nutrient by single feeding of native grass, technical guidance of sheep feeding and import of good gualified sheep.
