In - vivo evaluation of  the  efficacy of test anti - coccidial efficacy of salinomycin and amprolium carried out in two different trials in 228 commercial chicken revealed 100% efficacy against mixed eimeria sp on comparative evaluation with standed in feed anti - coccidials.  There was marked reduction in the oocyst output with increased body weight gain and improved feed conversation efficiency in the experimental study.

In - vivo evaluation of  the  efficacy of test anti - coccidial efficacy of salinomycin and amprolium carried out in two different trials in 228 commercial chicken revealed 100% efficacy against mixed eimeria sp on comparative evaluation with standed in feed anti - coccidials.  There was marked reduction in the oocyst output with increased body weight gain and improved feed conversation efficiency in the experimental study.

The present study was conducted to determine the effect of salinomycin at a concentration 60 and 120 ppm alone and with vitamin E or selenium on haematological and biochemical parameters and histopathological changes of the treated chicken. Salinomycin (120 ppm) induced decrease in body weight, feed consumption and feed conversion efficiency. In addition, when salinomycin (120 ppm) given with vitamin E, the body performance improved significantly, but when sodium selenite used, body performance significantly decreased. Salinomycin at concentration 120 ppm induced decrease in blood parameters (RBCs count, TLC count, Hb content and PCV %). Concurrent use of vitamin E with salinomycin leads to improvement of these parameters. Salinomycin at 120 ppm induced significant increase in enzymes activities (ALT and AST). The uses of vitamin E with slinomycin (120 ppm) caused significant decrease in these activities. In contrast to selenium, which reduce the activity of AST enzyme only. Salinomycin at 120 ppm decreased the total protein concentration and increased the level of creatinine and uric acid. Concurrent administrations of vitamin E or selenium with salinomycin have no effect on these parameters. At 120 ppm salinomycin, selenium increased the creatinine concentration in blood serum. The drug at 60 or 120 ppm induced various pathological changes in certain tissues (liver, heart, kidney and skeletal muscle) ranged from degeneration to necrosis of these tissues. Concurrent administration of salinomycin with vitamin E or selenium revealed that vitamin E decreased the pathological changes of studied tissues.

Objective: The objective of this study was to investigate the cause of death of large number of camels during an outbreak in Saudi Arabia. Material and methods: History was taken from the camel owners and breeders. Besides, clinical and post-mortem (PM) examinations were conducted. In this study, ten locations were surveyed and all camels were examined. Wheat bran was suspected as the source of the havoc. For establishing this assumption, a feeding trial was conducted with three camels, six mice, one rabbit and four of each chickens and ducklings using the incriminated wheat bran. Samples were collected from the suspicious wheat bran and the afflected animals, and were sent to international reference laboratories for diagnosis. The clinical signs elicited by the feeding trial were compared with the signs recorded in the outbreak. Results: The body temperature of the affected camels ranged from 36.4◦C to 41.9◦C. The clinical signs included hyper-excitability, muscle tremors, in-coordination of the hind quarters, sternal or lateral recumbence, inability to stand, and death. PM examination revealed no remarkable pathological changes in internal organs but the rumens were full of gases, and showed hyperemia and petechial hemorrhages. Within a period of twelve days from the onset of the crisis, 2,800 of the affected camels died. The clinical signs showed by the two camels in the feeding trial were similar to those observed in field outbreak. The tentative diagnosis of toxicosis, which was made based on the clinical signs was confirmed by the reference laboratories. Salinomycin (300 to 400 mg/Kg feed), Aluminium (230 ppm), Aspergillus clavatus and A. flavus were detected in the incriminated wheat bran. Conclusion: Salinomycin causes heavy mortalities in one-humped camels in the affected areas. Owners and breeders are adviced to avoid feeding low quality feed to their camels.
