Effect of Arsonic Acid Derivatives in Stimulating Growth of Chickens

A review on exposure and effects of arsenic in passerine birds

“…Some organic arsenicals such as roxarsone and 4-arsanilic acid are used as feed additives in the poultry industry in order to prevent coccidiosis, increase weight gain and feed efficiency, and improve meat pigmentation (Bird et al, 1949;Silbergeld and Nachman, 2008). Laying hens were fed 0, 11, 22, 44 or 88 μg/g roxarsone for 4 weeks (Chiou et al, 1997b).…”

Some Effects of Selenium, Arsenicals, and Vitamin B12 on Chick Growth

“…The reports by Bird et al (1949) and Morehouse (1949) that the latter compounds would improve chick growth under practical conditions with relative safety stimulated the desire to determine their possible value in the control of selenium poisoning. EXPERIMENTAL Chicks for this work were wing banded, weighed at one day of age and uniformly distributed into the various groups.…”

Unidentified growth factors in fish meal: Experiments with organic arsenic compounds in broiler diets

“…Libby et al (1955) observed growth increases of 5 to 6% in caged chicks receiving 0-009% arsenilic acid up to the age of 6 weeks. Bird et al (1949), using 0-005% arsenilic acid, also obtained growth increases in various experiments of 0-5 to 33% for chicks up to the age of 6 weeks. Demertzis (1971) found a 10% weight increase in cockerels receiving o-oi% arsenilic acid up to 8 weeks.…”
