Research results of environmental factors integrated influence on Tilapia reproductive characteristics when growing in waste and geothermal waters are described in the article.

We studied the acute and sub-chronical toxicity of the drugs on the basis of еnrofloxacin and colistin in laboratory animals. The drug according to GOST 12.1.007-76 apply to Class 3 danger - little dangerous. We studied the influence of the drug on the basis of composite еnrofloxacin and colistin at doses 0,5, 1,0 and 5,0 ml per 10 kg body weight on the clinical and biochemical indicators of the blood in piglets and calves. It was found that the therapeutical efficacy of new drug with kolibakterioze calves equaled 90,7%, piglets - 91,4%, while the effectiveness dizparcolum (base product) was 78,9% and 80,0% respectively.

The main symptom of porcine reproductive and respiratory syndrome is a violation of reproductive function in sows, which is accompanied by abortion, premature birth of dead, weak and ugly piglets and mummified fetuses. Clinical signs of disease in sows usually develop in late gestating (100-114 days). The greatest number of stillbirths and deaths of piglets in the first days of life in PRRS observed in epizootic period of flow, when passing in the enzootic period, the number of stillborn piglets markedly reduced. In households, where the vaccine against the disease was not carried out, re-epizootic outbreaks occur every 18-19 months, and continue 4-5 months. The number of stillborn piglets in the initial appearance of reproductive respiratory syndrome of pigs is higher than in its recurrence.
