- 出版タイプ： VoR2008-2010年度科学研究費補助金(若手研究(B))研究成果報告書 課題番号：20780194 研究代表者：高山耕二 (鹿児島大学農学部准教授)本研究は，ガチョウ放飼による果樹園の下草管理技術の開発を目的として，ガチョウの(1)除草，(2)産肉および(3)産卵能力について検討を行った．(1)ナシ園に放飼したガチョウのイネ科草本に対する嗜好性は他の植物種よりも高く，除草効果は顕著であった．(2) ナシ園放飼したガチョウ(補助飼料なし)の発育は増加傾向を示し，放飼終了時には2,820g に達した．(3) 草のみを採食したガチョウは配合飼料を給与した場合に比べ産卵率が低下したものの，約24％の産卵率を示した．以上より，果樹園におけるガチョウ放飼は下草管理に有効であることが示された．This study was carried out to obtain basic information on the effective use of geese for sustainablemanagement of vegetation in orchards. (1) Weed control: free-ranging geese tended to prefer grasses to other plants and the use of free-ranging animals for weed control in the orchard of Japanese pears was effective. (2) Meat productivity: the growth of the free-ranging geese (no supplementary feed) tended to increase gradually, and their mean BW was 2,820g at the end of the free-ranging period. (3) Egg productivity: free-ranging geese that were not provided supplementary feed in the pasture had lower egg productivity than did the geese fed with formula feed; however, an egg production rate of approximately 24% could be achieved. These results indicated that the use of free-ranging geese for weed control in the orchard was effective.
