Three polyether, ionophorous anticoccidial drugs were fed to broiler chickens in floor pens for 5 or 6 weeks, then withdrawn for 2 weeks or 1 week, respectively. With monensin and salinomycin there was evidence of increased feed consumption and compensatory growth during the first week, but not the second week, after drug withdrawal. There was no evidence of compensatory growth in birds fed lasalocid. Final weights were best in birds fed lasalocid and salinomycin in comparison with unmedicated… Expand
Research note: does compensatory growth occur following withdrawal of salinomycin from the diet of broilers?
Two floor pen studies were conducted to determine whether compensatory growth occurs following withdrawal of the anticoccidial drug salinomycin from the feed of broilers reared to 46 days of age.Expand
Effects of coccidiostats and dietary protein on performance and water consumption in broiler chickens.
Although a significant lasalocid SAA-sparing effect was not observed, diet X coccidiostat interactions were apparent and attributable to an apparent "protein-spared" effect upon body weight gain when salinomycin was fed in combination with the low protein diet. Expand
Effects of Amprolium (Anticoccidial) on Some Productive and Reproductive Parameters of Rabbit Doe (Oryctolagus cuniculus)
The main results showed that the pregnancy length of treated rabbits decreased with increasing doses of amprolium, with a significant difference on feed and water consumption, body weight gain, feed efficiency, average weight at birth, sex-ratio and viability of young rabbits in any of the study groups.

Effects of different concentrations of monensin and monensin withdrawal upon the control of coccidiosis in the turkey.
There was no significant difference in the weight gain or feed conversion of poults from 10 to 14 wk of age whether monensin was present in the feed or had been withdrawn, and no evidence of compensatory growth was found in the present study. Expand
Do Anticoccidials Interfere with Development of Protective Immunity Against Coccidiosis in Broilers
Results suggest that any drug of those tested could be used without interfering appreciably with protective immunity in chickens after inoculation with recent field isolates of Eimeria acervulina, E. tenella and E. maxima. Expand
Forty years of monensin for the control of coccidiosis in poultry.
The discovery, mode of action, and efficacy of monensin are discussed, together with matters of importance to the poultry industry such as commercial use, drug resistance, toxicity, pharmacology and residues, host immunity to coccidiosis, and effects in other avian species. Expand
Final-week performance of straight-run broilers as affected by early coccidiostat withdrawal followed by increased dietary salt.
Elevated salt levels do not appear to be a reliable means of offsetting reduced performance related to early coccidiostat withdrawal, nor were such performance problems demonstrable for lasalocid in these trials. Expand
Feed and water consumption and performance of male and female broilers fed salinomycin and maduramicin followed by a withdrawal ration.
A 3 x 2 factorial floor pen experiment was conducted to determine the effects of feeding salinomycin (60 ppm) or maduramicin (5 ppm) for 49 days followed by a 3-day withdrawal ration upon both maleExpand
Nicarbazin stimulates intestinal transport of L-leucine in rabbit.
Results obtained show that nicarbazin decreases L-leucine accumulation in the jejunal tissue, and increases mucosal to serosal transepithelial fluxes of this amino acid in a dose-dependent way, without modifying its diffusion across the intestinal epithelium. Expand

Current diagnostic criteria for ionophore toxicity are unsatisfactory and there is a clear need to investigate other diagnostic approaches. Expand


The Effects of Feed Restriction Time on the Growth and Feed conversion of Broiler Males
The weight of the digestive system was significantly larger for the birds limited in feeding time to 15 minutes every four hours for broiler male chicks, and feed conversion was consistently improved by limiting feeding time. Expand
