Реакція пілоричної зони шлунка свиней на згодовування пробіотичних препаратів
The type of animals feeding has a considerable influence on the alimentary canal morphological peculiarities; they connect the structural changes in the animal bodies with their productivity formation in the feeding conditions. It is very important to take into account this point feeding the animals by new feed additives, because the aim is to minimize the adaptation cost for major diet energy use for synthetic processes but not to eliminate stress. That’s why the goal of our work was to research the influence of feed additives feeding on the structure of young pigs’ pyloric area. The stomach of slaughtered pigs was prepared, weighted, the samples were taken and fixed in neutral formalin. Then the researches of wall thickness of the mucous and serous-muscle membranes have been conducted. As a result it was investigated that enriching of young animals diet by the researched preparations doesn’t have considerable influence on the stomach weight. The peculiar feature of stomach pyloric area of early weaned pigs is thickening of the sero-muscular coat by 18.5%, and a tendency to increase the wall thickness of 11.9% at nearly the same size mucosa. The young pigs for breeding has tendency for increasing the thickness of sero-muscular coat by 14.6%, while the figures of the wall thickness and the mucosa has a tendency to bulge. The stomach pyloric area of fattening young pigs has the thickness both of walls and some separate stomach coats using all the researched feed additives.
