The present study aimed to examine the effect of dietary Ptecticu tenebrifer powder mixtures as pet dogfeed ingredients on crude fat and ash digestibility. Three groups of feeds Feed A, Feed B, and Feed C supplied from three farms were fed to a total of 45 dogs. The dietary Ptecticu tenebrifer powder mixture were prepared by mixing 25 g of Ptecticu tenebrifer powder with 100 g of canned food. Feed A, Feed B, and Feed C containing dietary Ptecticu tenebrifer powder mixtures were fed to 15 dogs of each breed of bichon, poodle, and chihuahua that were divided into three groups following a completely randomized design. For measuring the crude fat and crude ash digestibility, manure of each dog breed from each group were collected. Crude fat digestibility was not statistically significant among the dog breeds fed with feed C (p>0.05), but overall there was a statistical difference between the feed and the group by dog breed (p<0.05). In terms of crude ash digestibility, the three types of feed showed differences with respect to dog breeds (p<0.05). However, the group with no significant difference was observed in Feed B by dog breed (p>0.05). In conclusion, feeding Ptecticu tenebrifer powder mixture to dog breeds had no positive effect on the crude fat and ash digestibility and can be used as pet dogfeed ingredients.

수집종 아주까리 40종의 유전자원을 농촌진흥청 농업생명공학연구원 유전자원과로부터 분양받아 바이오디젤 가능 작물로서 조지방 및 지방산 분석결과는 다음과 같다. 수집종 아주까리 종자의 gas chromatogram은 6개의 피크를 보였고, ricinoleic acid의 retention time은 12.7분대이었다. 아주까리 수집종의 평균 기름 함량은 44.6~49.4%이었으며, 최저 41.4%와 최고 52.2%로 10.8%의 차이가 있었다. 지방산 조성은 불포화지방산이 97.6%로 대부분이었으며, 포화지방산은 2.4% 정도로 낮은 함량을 보였다. 지방산 조성은 87.3%가 ricinoleic acid이었으며, oleic acid와 linoleic acid가 각각 4.6%, 5.2%이었다. palmitic acid와 stearic acid의 함량은 1% 내외로 차이가 미미하였고, linolenic acid의 함량은 0.6% 정도로 가장 낮았다.
