    condition. Three supplemental betaine levels (0, 0.6 or 1.2 g kg-1) were fed to 189 mixed-sex broilers chicks which were randomly assigned to 9 floor cages in a completely random design with 3 replicates. To simulate a coccidiosis challenge, at day 28 of age the chickens were inoculated with a mixed culture of Eimeria tenellaeimeria tenellaSubject Category: Organism Names

    subjected to coccidiosis-infection. The IgA content of both sera (p<0.05) and gut tissue (p<0.01) were increased by added betaine to diet. Variations in osmolarity and moisture of both ileum and cecum contents were similar and they were significantly (p<0.001 and p<0.05, respectively) decreased in day 42 measurement by betaine inclusion into the diet. Positive effects of dietary betaine on performance, immunity and digesta moisture and osmolarity redoubles the importance of adding betaine to diet of broilers especially, in stress conditions like coccidiosis-infection.
