Abstract     In the research the effect of clinoptilolite of own production on the breeding of broilers was examined. The folllowing facts were examined: the effects on the microclimate in the buildings, on the weight of the animals, yield of fodder conversion, on red blood cell count and histological picture of the liver. In the macroexperiment the clinoptilolite in fooder and in bedding caused ammonia reduction in the air of the majority of buildings. Ammonia reduction in the air was highest in the buildings where clinoptilolite was added both to fodder and bedding. The ammonia concentrations in the air of the test groups of animals were by 28.3% lower in comparison with the control ones. In the buildings where clinoptilolite was added only fodder the ammonia concentrations were by 14.2% lower, and in the buildings with clinoptilolite added only to beddings they were by 7.9% lower. As additive added to fodder and bedding clinoptilolite influences the increase in final weight of the animals and fodder conversion. In the buildings with clinoptilolite in fodder the weight of the animals was on the average by 5.3% higher and in the buildings where clinoptilolite was added to bedding it was on the average by 1.52% higher. In these buildings the fodder conversion was improved; mostly the fodder consumption was not higher than 2.145 kg in order to reach 1 kg of liveweight of the animal. In the microexperiment the highest final weight was achieved with animals with 2% of clinoptilolite added to fodder. That means an increase of 3.8% in comparis on with the group of animals that did not receive clinoptilolite in fodder. The same animals had the lowest fodder conversion during the research. The analyses of zinc in the blood serum of broilers showed that quanitities were the highest at the end of the research in the group that received 2% of clinoptilolite in fodder.(Abstract truncated)
