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.

Analysis of health condition, milk production and reproduction of cows when using in rations food additives based on needles
In order to increase the productivity of dairy cows and maintain their health, the search for complex food additives with multifactorial positive properties is continuously carried out. A scientific and economic experiment of a new food additive based on needles developed by the technical and research centre “Khiminvest” has been conducted. The experiment has been conducted by the method of groups-analogues on highly productive cows. Food additive based on pine needles has had a positive impact on milk productivity, milk protein content, carotene and nonspecific immunity, as well as individual indicators of reproduction. The effectiveness of the additive has been 29.50 rubles per 1 cow a day.
Comparative evaluation of methods and justification of the operational method for experimental determining the isomerization proportion of lactose into lactulose
The article gives a comparative assessment of methods for experimental determination of lactulose. It has been established, that the polarimetric method of analysis is the most appropriate one for the operational method of experimental determination of the lactose isomerization fraction into lactulose.
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.
Intensive production technology of a lactulose-based feed additive with high bifidogenic activity
The article describes the prebiotic action mechanism, in particular lactulose. The article presents the production technology of lactulose syrups. The authors give the results of using the lactulose-based prebiotic additive with weaned piglets.
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.
