| dc.description.abstract | The aim of this research was to study the resistance against S. pulloruminfection on IPB- D1 crossbreed, kampong and commercial broiler chickens. Chicken IPB-D1 is derived from a cross between a male line of F1 pelungx sentul (PS crossbreed) with a female line of F1kampongx broiler parent stock, Cobb strain(KB crossbreed). A total of 31 chickens consisting of IPB-D1 (11 birds), kampong (13 birds) and commercial broiler (13 birds) were used in this research. All of chickens are collection of Division of Animal Breeding and
Genetics, Department of Animal Production and Technology, Faculty of Animal Science, Bogor Agricultural University (IPB). The experiment was designed using a completely randomized design.Biological assays of resistance indicator were measured, including leukocytes profile (leucocytes concentration and its differentiation, H/L value), and clearance test using S.pullorum. Data from all observations were statistically analyzed using analysis of varian. The result of this research showed that the value of leukocytes profile and body resistance parameters from IPB-D1 crossbreed and kampong chicken were not significantly
different, but on both these chickens, these parameters were significantly different than those in commercial broiler chickens. The conclusion is the IPB-D1 crossbreed biologically have the same resistance against S. pullorum infection with the kampong chicken and it higher than commercial broiler chickens. | id |
