“…Morrison et al (1961) developed an anticoccidial index. The indices reported herein were calculated on the basis of percent survival, plus percent gain of initial weight, minus fecal score, minus lesion score, minus oocyst score.…”

Efficacy of Salinomycin and Stenorol against Various Species of Eimeria and Effect on Chick Performance

Three experiments were designed to test the efficacy of salinomycin and stenorol against infection by various Eimeria species on cage reared broiler type chicks. Efficacy was based on a coccidial index. Sixty parts per million salinomycin alone or in combination with 50 ppm 3 nitro significantly improved the index over basal treatments or when 3 nitro was used alone. The differences in index values recorded for coban and salinomycin were not significant. Stenorol significantly improved the index and appeared to be a most effective anticoccidial product. Broiler chickens reared in floor pens to 8 weeks showed a significant reduction in weight gain when the diet contained salinomycin +3 nitro or coban. Stenorol at 3, 6, or 9 ppm reduced body weight, with linear regression for this effect being highly significant (P less than .01). No coccidiosis was observed.

“…This might be explained as Zoalene affects sporulation rate more in E. tenella. Morrison (1961) reported rate of weight gain as 57% and 61% and the difference could be due to the fact that he used 5x105 oocysts of 5 different species for inoculation. Also Chapman (1976) reported weight gain of 69.7% using 2x105 oocysts of E. tenella.…”

“…The maximum recommended dose for chickens is 0.0125% wt:wt in the food, and poor growth and even toxic symptoms develop if this is much exceeded. In this respect poor growth and reduced efficiency of food conversion were reported by Morrison et al (1961), Bigland et al (1963) and Kaemmerer (1965). Nervous signs were observed by Brion et al (1963) and Bigland et al (1963), but histological brain lesions were seen only by the former workers.…”

Depression and ataxia was seen in 24-day-old chicks accidentally fed excess zoalene from 14 days of age. The presence of a small amount of furazolidone in the ration probably exacerbated the effect. There were no deaths. No other causes could be found for the condition and replacing the rations with food containing less than the recommended level of zoalene and no furazolidone resulted in recovery within 4 to 5 days. In an experimental study the syndrome was reproduced in baby chicks with as little as 2(1/2) times the recommended level of zoalene in the food. Increasing the amount of zoalene hastened the onset and increased the severity of symptoms and markedly depressed weight gains; the addition of a small amount of furazolidone had a synergistic effect. Inappetance may be largely responsible for the depression in weight gain, and damage to Purkinje cells seems to account for the ataxia and nervous signs. In laying birds 10 times the recommended level of zoalene in the food over 30 days caused inappetance, cessation of egg production, and progressive weakness, but no nervous signs.
