Trong thời gian thực hiện (2005-2007), ba mục tiêu của dự án, bao gồm: 1) Cải thiện lĩnh vực và chẩn đoán phòng thí nghiệm của preweaning tiêu chảy, 2) Sản xuất và thử nghiệm của locallyproduced E. vắc xin coli; 3) Phát triển một kế hoạch quản lý cho preweaning tiêu chảy bằng cách sử dụng một mô hình cải tiến liên tục (CIP) đã được tiến hành và hoàn thành. Một số thành tựu này là: 1) Một thủ tục chẩn đoán nguyên nhân chính gây ra tiêu chảy ở lợn sữa đã được áp dụng thành công tại Khoa Vi trùng, NIVR | Collaboration for Agriculture and Rural Development CARD Program RESULTS ON STRENGTHENING DIAGNOSTIC CAPACITY AND CONTROL OF DIARRHOEA IN SUCKLING PIGS Project title Diagnosis and control of diarrhoea in suckling pigs Project code CARD 001 04VIE Authors Do Ngoc Thuy1 Cu Huu Phu1 Au Xuan Tuan1 Nguyen Xuan Huyen1 Truong Van Dung1 Tony Fahy1 Steve Driesen2 Karen Moore2 Aileen Vanderfeen2 Darren Trott3 Collaborating organisations 1 National Institute of Veterinary Research 2 Pig Research Unit Victorian Department of Primary Industry Melbourne Australia 3 The University of Queensland Australia SUMMARY During the implementation time 2005-2007 three objectives of the project including 1 Improved field and laboratory diagnosis of preweaning diarrhoea 2 Production and testing of locally-produced E. coli vaccines 3 Development of a management plan for preweaning diarrhoea using a continuous improvement CIP model had been conducted and completed. Some achievements are 1 A diagnostic procedure of six major causes of diarrhoea in suckling pigs has been applied successfully at Department of Bacteriology NIVR. 2 A vaccine containing E. coli strains bearing full pathogenic factors fimbriae toxins has been produced and proven safe and effective in laboratory and in the field. 3 An continuous improvement model focused mainly on management of sows during farrowing and lactation has been developed and utilized in order to improve pig production and minimize the losses due to diarrhoea in suckling period. 1. Introduction Diarrhoea during the suckling period has been recognised as the principle health problem affecting both smallholder and commercial pig production in Vietnam. Previous research 4 7 has confirmed the presence of a new fimbrial type in E. coli strains causing colibacillosis in Vietnam that would not be controlled by existing vaccines. Existing vaccines are currently imported into Vietnam at considerable cost. In addition there are many other causes of suckling diarrhoea .
