Investigation of influence of complex probiotic preparation Laktimet obtained by means of cultivation of bifidus bacteria and lactic acid bacillus on morphological indexes of pancreatic gland of laying hens was realized in the conditions of the Republic of Belarus. Two groups of laying hens of 121-130 days old were used in the experiment. The experimental hens were given probiotic Laktimet with water in dose of 1 ml/head every day in 4 cycles during 7 days and with 7 days intervals. Total condition, dynamics of body weight, and egg production were estimated. Research results showed that body weight of experimental hens increased on 6,4 % on the 10-th day; on 12,1% - on the 24-th day; on 6% - on the 40-th day; and 7,5% - on the 50-th day of experiment. Pancreas weight of experimental hens increased on 4-9%. Acinus size increased on 11%. Morphological indexes in exocrine pancreatic cells showed that altitude of basal pole increased on 3-7%. Application of probiotic Laktimet rendered positive influence on laying hens that was evident in increasing of their productivity (there was an increasing of live weight on 4-8%, and egg-laying capacity – on 18-33%). The positive dynamics of the majority of morphofunctional indexes of exocrinous and endocrine parts of pancreatic gland proved its significant role in maintenance of general state of laying hens and metabolic processes
