The effect of feed with extruded grains and phytobiotics on meat productivity and health of feeder young cattle
The article describes the results of a comprehensive study extruded feed and extruded feed with phytobiotics influencing on the health and growth of feeder young cattle (Ayrshire breed). The research methods: clinical, microbiological, statistical, biochemical analysis. The results of the study showed that the use of extruded grains and extruded grains with phytobiotics increases meat productivity, has a positive impact on the development of animals, reduces the cost of production per production unit.

Optimization of veterinary and sanitary expertise of honey based on mathematical modeling of the dependence of the diastaznoe number on the amount of pollen grains
The present paper contains results of a laboratory expertise of 20 honey samples from different regions. The correlation dependence of the diastaznoe number on the amount of pollen grains in the sample was analyzed, a statistically significant mathematical model of interrelation was tested, on the basis of which the average expected limits of the honey quality index by the diastaznoe number were calculated. This allows one to obtain a quick result, without spending a detailed laboratory expertise of samples.
The effect of yeast products on the milk production of cows
The article presents the study results of the effect of the yeast supplements “Optisaf” and “Progut Rumen” on the productivity and quality milk indicators from highly productive cows. It has been established that at the doses recommended by the manufacturer, their use improves the eatability of feed of the basic diet, increases the milk productivity and leads to an increase in the mass fraction of fat.
The effect of additives based on fodder yeasts on some biochemical indicators of blood in lactating cows
The article presents the results of studying the effect of yeast-based feed additives on metabolism of lactating cows. It has been stated that in the doses recommended by the manufacturer they do not have a negative impact on metabolism. The use of fodder yeasts allows to optimize the level of protein metabolism in animals.
