anglais. The aim of the project was to investigate the local processing plant by-products using high-quality output options deer production. The objectives were: to investigate rape cake (by-product of rapeseed oil production) use patterns of deer feed rations and their impact on productivity, deer natural food background and environmental relationships animals’ faecal chemical and microbiological composition of 1 time per month, deer digestive tract morphology studies. Rapeseed cake into the feeding of deer increased their productivity Deer carcass lean of animals’ in the experimental group was 67.23%, 5.66% fat and 27.11% bones. Muscle and fat of deer carcass in test group were by 4.43% and 2.32% percentage higher while the proportions of bone 6.75% lower than in the control group. Accordingly, the proceeds from the sales of meat from an average of one animal of experimental red deer group were 15.50 Ls or 4.85% higher revenues than in the control group of deer carcass muscle. Rape-cake into the red deer rations did not change the morphofunctional state of the animals’ digestive tract. The present study describes results of histological and immuno-hystochemical (IHC) investigations of different parts of digestive tract and diffuse neuroendocrine system of captive farmed red deer (Cervus elaphus) in Latvia.
