Intestinal contents from 12 scaled quail (Callipepla squamata), 10 bobwhite quail (Colinus virginianus), 20 harlequin quail (Cyrtonyx montezumae), 35 California quail (Lophortyx californicus), 15 Gambel's quail (Lophortyx gambelii), and 29 mountain quail (Oreortyx pictus) were examined for coccidian oocysts. Only 18 (14.9%) of 121 birds had coccidian oocysts in their feces at the time of collec...

Two commercial, pure broiler lines with different susceptibility to coccidiosis were used to fine-map QTL associated with the previously identified marker LEI0101, located at 259 cM on chromosome 1 and shown to be significantly associated with disease resistance. Eight additional microsatellite markers linked to LEI0101 were used for genotyping of F(1) parents and F(2) offspring (n = 314), and ...

To study the immune response in poultry, a non-specific host for pheasant Eimeria colchici coccidium, ten-day-old chickens were each orally inoculated with 106 oocysts. For determination and comparison of coccidia invas...

A study was carried out to investigate the effects of a drug-free feeding program on broiler performance and intestinal morphology. Chicks vaccinated against coccidia were randomly assigned to 4 dietary treatments: 1) negative control (NC), basal diet; 2) positive control (PC), diet 1 + Lincomycin; 3) program 1 (PG1); diet 1 + Bio-Mos, Vegpro, MTB-100, Acid Pak 4-Way, and All-Lac XCL; 4) and pr...
