Development of a multivalent oral vaccineagainst chicken coccidiosis using localisolates”Ten attenuation trials were carried out inchicken using the 10 field isolates of Eimeria tenellacollected from Coimbatore, Namakkal, Pakkam,Vellore, Tiruchitrampalam, Thanjavur, Nellore,Chittoor, Bangaluru and Nagpur. A markedreduction in the prepatent period from 142 to 136hours with reduction in the gross lesion score from+3 to +1 were also observed in most of the fieldisolates subjected to attenuation indicatingreduction in virulence. Molecular analysis of variousEimeria species were carried out using ITS andSCAR primers for E.tenella, E.brunetti, E.maxima,E.acervulina, E.necatrix and E.mitis to evaluate themolecular changes during attenuation.ANIMAL PRODUCTIONPreparation of Dietetic frozen bifido yoghurt.Frozen yoghurt is a dessert similar to icecream but lower in fat. Frozen bifido yoghurt is aunique way of combining the characteristics of icecream and the therapeutic character of yoghurt.Incorporation of Bifidobacterium bifidum, a probioticorganism with traditional yoghurt will be highlybeneficial to the consumers. Bifido yoghurt madewith artificial sweetners will not only be highlybeneficial in exerting probiotic and possibletherapeutic effects but also in avoiding health risksassociated with caloric sweetners.Formulation of a sugar free icecreamSucralose could be satisfactorily used in thepreparation of acceptable quality ice creamreplacing even upto 100 percent of sugar. Further, itwas observed that a maximum of 50 percent ofAcesulfame k with sugar and 75 percent ofNeotame with sugar could be satisfactorily used inthe preparation of good quality ice cream.Development of synbiotic ice creamAbout 100 ml of control, probiotic andsynbiotic ice creams were served to the volunteersfor 15 days and their faecal samples were analyzedfor pH, L. acidophilus and coliform counts on days0, 7 and 15.
