中文摘要 | 採用畜產試驗所育成之4種近親品系與其二元雜交土雞、臺灣商用紅羽土雞(以下簡稱紅羽土雞)以及2種雜交土雞(紅羽母雞分別與配臺畜公十一號公雞及中興大學L2公雞)等8種不同遺傳來源的土雞,定期採血監測抗體力價及篩選鄒白痢雞,藉此瞭解所施打之疫苗是否能有效且穩定地增加其免疫力,作為日後預防性投藥與疫苗使用之參考,以期建立土雞最少疾病種原族群。試驗結果顯示,於正常防疫計畫下,依6種疾病血清抗體力價的檢測結果,4種近視品系土雞之新城雞病(New Castle disease,ND)、傳染性華氏囊病(Infectious bursal disease,IBD)與傳染性支氣管炎(Infectious bronchitis,IB)等抗體力價均表現良好;其於8與18週雛白痢(Pullorum disease,PD)之陽性檢出率則介5~30%之間,經淘汰陽性反應雞後於35週齡之雛白痢發生率降為0~6.9%二元種土雞除傳染性喉頭氣管炎(Infectious laryngotracheitis,ILT)外,抗體力價表現均良好,雛白痢陽性檢出率則介於0~16.7%之間。紅羽及2種雜交種母土雞之抗體力價表現均良好,而雛白痢,8週齡之陽性檢出率為5.06%,18週齡者則增至14.9%,雖已於19週齡淘汰陽性反應雞,然其陽性檢出率仍有隨週齡增加而上升之趨勢(22週齡21.8% vs. 35週齡27.1%)。因此,種土雞場除了有適當之防疫計畫外,尚必須加強雛白痢之篩選。 |
英文摘要 | The chickens surveyed in the present study included four inbred lines and one two-line cross of Taiwan Country chicken (TC) bred by Taiwan Livestock Research Institute (TLRI), one commercial stock of red feathered TC (RF) and two breedcrosses from mating of RF females with either TLRI Taishu Male No. 11 or L2 males of National chung-Hsing University. The chickens were periodically blood sampled for the surveillance of serum antibody titers and pullorum disease (PD) for the effectiveness of vaccination program to enhance immunity. It was expected to be a good reference of medication and vaccination for establishing the least pathogen genetic stock of TC. The results of antibody titers of six different diseases indicated that under normal vaccination program, good levels of antibody titers to New Castle disease (ND), infectious bursal disease (IBD) and infectious bronchitis (IB) were found in these four TLRI inbred lines. The percentages of positive reacting chicken to PD in these four inbred lines were among 5 to 30% at 8 and 18 weeks of age, and after culling the positive reacting chicken, it was reduced to 0~6.9% at 35 weeks of age. Except for the infectious laryngotracheitis (ILT), the levels of serum antibody titer in the two-line cross TC expressed very well and the percentages of positive reacting chicken to PD were 0-16.7%. The serum antibody titer levels of RF and their breedcrosses were expressed very well and the percentages of positive reacting chicken to PD were 5.06 and 14.9% at 8 and 18 weeks of age respectively. However, even after culling the positive reacting chicken 19 weeks of age, there was a trend to increase the percentage of positive reacting chicken to Pd with age. They were 21.8 and 27.1% at 22 and 35 weeks of age, respectively. Therefore, the breeders not only have to adopt an appropriate vaccination program, but a strict surveillance program to pullorum disease. |
