Abstract

The object of this experiment was to investigate the food habits of sika deer fed with various roughage sources. The feeding trials were conducted at Chungnam National University and Unbong Animal Genetic Resources Station in 2007. The experimental roughages sources were five including 25 species in all; grass sources; 5 species(Lolium perenne, Festuca arundinacea, Poa pratensis, Agrostis alba and mixed grass), legume sources; 5 species(Trifolium pratense, Medicago sativa, Trifolium repens, Melilotus officinalis and Vicia villosa), browse sources; 5 species(Quercus serrata Thunb., Prunus jamasakura Sieb., Quercus aliena Blume, Robinia pseudoaccacia and Pinus densiflora), weed sources; 5 species(Artemisia princeps Pampanini, Erigeron canadensis, Alopecurus aegualis Sobolewski, Echinochloa crusgalli var. frumentacea(Roxb.) Wight and Rumex crispus), and native grass sources; 5 species(Zoysia japonica Steudel, Agropyron tsukushiense var. transiens(Hack) Ohwi., Arundinella hirta(Thunb.) Tanaka, Miscanthus sinensis Anderss and Phragmites comunis Trin). Five sika deer were selected which had nearly the same body weight(average 92.5kg) as experimental animal. Experimental roughages were prepared by 0.5kg(DM basis) per 1 species fed to sika deer, and the experiment was carried out from 08:00 to the next day 06:00. The chemical composition and dry matter digestibility of each roughage source and species were significantly different at the sampling area, plant species, growth stages and cutting period. The sika deer ate more roughages which had low fibrous contents, but high dry matter digestibility. Among all the 25 species of roughages, the favorite intake species ranking by sika deer was observed like this: Quercus aliena Blume, Prunus jamasakura Sieb, Quercus serrata Thunb. and Trifolium pratense, respectively, and the lower intake species was Phragmites comunis Trin. On the other hand, compared to each roughage source, total intake amount by sika deer was showed as browse(36.5%), Legumes(34.2%), grasses(14.0%), native grasses(13.5%) and weeds(1.8%), respectively. Based on the result, the food habits of sika deer seems to be closer to typically browser type.

본 연구는 2007년 3월부터 12월까지 충남대학교 부속사육장 및 전북 남원시 운봉읍 소재 가축유전자원시험장에서 수행하였다. 공시시료는 화본과목초(grasses)는 Lolium perenne, Festuca arundinacea, Poa pratensis, Agrostis alba 및 mixed grass의 5종과, 두과목초(legumes)는 Trifolium pratense, Medicago sativa, Trifolium repens, Melilotus officinalis 및 Vicia villosa의 5종, 수엽(browse)으로 Quercus serrata Thunb., Prunus jamasakura Sieb., Quercus aliena Blume, Robinia pseudoaccacia 및 Pinus densiflora의 5종과 잡초(weeds)는 Artemisia princeps Pampanini, Erigeron canadensis, Alopecurus aegualis Sobolewski, Echinochloa crusgalli var. frumentacea(Roxb.) Wight 및 Rumex crispus의 5종을, 야초(Weeds)는 Zoysia japonica Steudel, Agropyron tsukushiense var. transiens(HACK) Ohwi., Arundinella hirta(Thunb.) Tanaka, Miscanthus sinensis Anderss 및 Phragmites comunis Trin의 5종 등 총 25종을 공시하였다. 시험축은 꽃사슴(수컷) 5두를 공시하였으며, 평균체중은 92.5 kg이었다. 시료는 초종 당 건물기준으로 0.5 kg씩 급여하여 시험하였으로 시험결과는 다음과 같다. 공시시료의 조사료원별로 분석한 화학적 성분과 건물소화율은 대체적으로 채취장소, 초종, 생육단계 및 예취시기에 따라 차이를 보였다. 채식량, 채식비율 및 채식순위는 초종 및 수종에 따라 차이를 보였으며, 대체적으로 섬유소물질의 함량이 낮은 반면에 건물소화율이 높은 조사료를 더 즐겨 채식하는 양상을 나타내었다. 꽃사슴은 Quercus aliena Blume(갈참나무 잎, 500g)을 가장 즐겨 채식하였으며, 다음은 Prunus jamasakura Sieb.(벚나무 잎, 491g)과 Quercus serrata Thunb.(졸참나무 잎, 491g), Trifolium pratense(red clover, 481g) 순으로 즐겨 채식하였던 반면에, Phragmites comunis Trin(갈대, 8g)를 가장 적게 채식하였다. 꽃사슴의 채식습성은 수엽 36.5%, 두과목초 34.2%, 화본과목초 14.0%, 야초는 13.5% 및 잡초를 1.8% 채식하였던 것으로 보아 채식습성은 전형적인 수엽채식형(browser type)에 가깝다고 하겠다.
