Abstract

This work deals with histrostructural, histochemical and morphometric parameters of hen – broilers jejunum wall at the influence of different doses of probiotic supplements. The experiment was carried out under the production conditions on chickens – broilers in the number of 1200 heads. It was formed four research groups of two–days chickens – broilers, with an initial body mass of 37–40 g (300 heads in each group): the first group – received standard diet with added probiotic supplements «Probion forte» at a dose of 1 g/kg, the second –«Probion forte» at a dose of 0.5 g/kg, the third group has got fodder with probiotic additive “Bio Plus2B” at a dose of 0,4 g/kg, the fourth group – control, which were fed a basic ration without adding any preparation. On the 15, 30, 42 day of the experiment 10 animals from each group were taken out of the experiment for further morphological researches of tissues. At histo–morpho–metrical research of jejunum wall in the process of growth and hen–broilers development it was found, which is by the 15th day in chickens of the first and second groups, which were given «Probion forte»with forage at a dose of 1 g/kg and 0,5 g/kg of mixed fodder, villus height and crypt depth mucosa were significantly increased, and in the third group of poultry which were fed with a probiotic supplement «BioPlus2V» at a dose of 0.4 g/kg tendentiously, compared with control. At the 30th day of the experiment it were observed a slight decrease in villus height in all experimental groups with further growth on the 42nd day. The most probable increasing of villus height and thickness of the muscular layer was installed in the jejunum of chicken – broilers, which were fed with probiotic «Probionforte» at a dose of 1 g/kg. In the mucosa of chicken – broilers of the first, second and third groups as well installed a significant increase of the height of columnar epithelial villi and the relative increase in the content of glycosaminoglycans and PAS – positive substances of goblet cells.
