中文摘要:
本研究乃為因應行政院農業委員會家畜衛生試驗所水禽小病毒感染症活毒減毒疫苗及油質死毒疫苗、水禽雷氏症等鴨用疫苗之研發及相關疫苗檢定等之需,進行最少病原番鴨設施、飼養管理及疾病監測的規劃與執行,以期增加實驗用番鴨受精蛋與雛鴨之生產與供應。於2006年,有關於動物房設計與施工,係利用舊有平房約38坪,改建成光控溫控鴨舍一棟二房間,每間飼育室?15坪。動物房以水簾控溫,飼育室全不透光全程以微電腦控制光照,飼養床面採高床設計,高床網採直徑5.6mm之鍍鋅鐵條。同年秋由畜產試驗所宜蘭分所引進番鴨雛鴨89隻,先於另一處房舍內進行隔離檢疫,待抗體檢測無水禽小病毒抗體後,正式移入本設施之一房間內飼養。飼養管理以高生物安全措施方式,人員進入時均經全身沐浴,更換乾淨工作服,飼料經幅射滅菌。自2007年2月開始產蛋,至2008年4月底已生產供應番鴨蛋4,009枚。另一方面,選取前述番鴨群所生產的受精蛋以碘酒消毒外殼後,孵化繁殖二代番鴨80隻,於2007年5月移入本設施第二間房間,以相同方法飼養管理,至2008年4月底已生產2,745枚。其間,將二代番鴨小鴨送請國立中興大學獸醫學院檢測水禽小病毒、新城病、家禽流行性感冒、傳染性華氏囊病、里奧病毒等抗體,結果均為陰性,符合本所相關實驗的動物品質要求。又配合孵化時程,依據番鴨光照需求設置光照控制,可有效調節產蛋期。這些清淨無污染番鴨群將進一步進行更多種疾病之監測,以進一步提升其品質,從而強化我國生物科技或生醫產業之發展環境,有利於生物學、生物醫學或動物醫學之研究與發展。
英文摘要:
With a view of self-supply of fertilized Muscovy duck eggs for the production of duck live and/or inactivated parvovirus vaccines and for the need of Pasteurella anatipestifer vaccine development, this study was schemed to set up an animal house appropriate for raising Muscovy ducks of minimum disease-free. An old plain house, about 125 square meters, at the Animal Drug Inspection Branch Institute, Animal Health Research Institute, was restructured and remodeled into animal house with two closed rooms. The size of each animal room is about 50 square meters and is equipped a water cooling and light control system to lower room temperature during warm season and to control artificial lightening time as breeding duck needs by a micro-computer control system. The slotted surface flooring of animal rooms is the galvanized wire plates and wire’s diameter is 5.6mm. In December 2007, 89 Muscovy ducklings of the first herd were first introduced from the I-lan Branch Institute, Taiwan Livestock Research Institute into a quarantine room at the Branch Institute. The testing samples collected from the ducklings were sent for proving them free from duck parvovirus infection. Then the ducklings were moved into one of animal room. Duck care and management follows the common biosecurity measures. In general duck keepers bath and change clean clothes before entering. Feed is treated by radiation sterilization. This first herd started egg production during February, 2007, and totally produce 4009 of eggs at end of April, 2008. For setting up the second herd, fertilized eggs produced from the first herd were selected and each egg surface of the eggs was disinfected with iodine tincture and then used for hatching. Samples collected from the ducklings of the second herd were also sent to an animal disease center for disease monitoring and surveillance, and antibody tests against parvovirus, Newcastle disease, avian influenza, infectious bursa disease and avian reoviruses were proved all negative, and these results indicated Muscovy fertilized eggs produced by this establishment meet egg requirements for experimental use of this Institute. In addition, the shift of egg production period by light control is also shown by this study. The feasibility of egg production period shift is thought to be good for whole-year production of fertilized Muscovy duck eggs for experimental use. Based on this study, further researches will be focused on upgrading disease free status of the herd by more extensive disease monitoring and surveillance and therefore, more institutes could make more use of the benefits of these produced eggs in research and development of biology, biomedicine or animal medicine.
