Shojaei SR, Hajikhani R, Malekan M, Anooshepour A., Effect of coccidiosis on serum carotenoids in Arbor-acres and Ross 308 broilers, Onl J Vet Res., 26 (9): 655-660, 2022. Coccidiosis in poultry is associated with malabsorption that reduces serum albumin, protein and carotenoids but in chickens depends on breed, sex, feed, Eimeria species, intensity, severity and immunity. Twenty 20 Arbor-acres and 20 Ross 308 one day broilers were inoculated on day 12 into crop with 100 ul sporulated oocysts of Eimeria acervulina, Eimeria maxima, Eimeria necatrix and Eimeria tenella. Blood was taken on day 3, 5 and 7 after challenge and serum carotenoids measured by n-hexane method. Compared with non-infected controls, infected Ross 308 showed sharp ~60% drops in serum carotenoids 5 to 7 days after challenge whereas Ann Arbor broilers only declined ~38% (P < 0.05). Results suggest that Arbor Acres broiler may be more resistant and/or maintain intestinal absorption.


Key words: carotenoid, broiler, coccidiosis, Arbor-Acres breed, Ross 308 breed.
