A survey into the prevalence of poultry helminths in northwest Arkansas commercial broiler chickens.

A 12-month survey was conducted to determine the prevalence of poultry helminths in Northwest Arkansas commercial broiler chickens. Intestinal tracts from market-ready broilers were collected weekly from two commercial broiler companies; a total of 3542 intestinal tracts were collected for parasite enumeration from 67 company A and 52 company B farms. Ascaridia galli was found on 37.3% of company A farms and 3.9% of company B farms, Raillietina cesticillus was found on 67.2% of company A farms and 69.2% of company B farms, and Heterakis gallinarum was found on 7.5% of company A farms and 1.9% of company B farms. No other parasitic helminths were found. No significant relationship was detected between grow-out feed efficiency and helminth infection rate or magnitude.
