The influence of aspen cell juice on morphological and biochemical parameters of broiler chickens’ blood

The study presents the results of the research of the influence of biologically active additive - aspen cell juice, on morphological and biochemical indices of blood of cross-country broiler chickens "Isa-15." The research was carried out at the Chair of Technologies of Processing and Storage of Livestock Products and on the basis of Research Testing Center for the Quality Control of Agricultural Raw Materials and Food Products of FSBEI HE "Krasnoyarsk State Agrarian University," as well as poultry farms "Krasnoyarskaya" of JSC "Sibirskaya Guberniya" of Berezovsky area of Krasnoyarsk Region. For the experiment three groups of broiler chickens were formed - one control and two experimental groups, 25 heads in each. Aspen cell juice (ACJ) was obtained at Siberian Institute of New Technologies (Krasnoyarsk) by pressing in a screw feeder made of crushed aspen wood. The product was a clear, greenish liquid and was biologically active additive. Aspen cell juice was given to the bird during morning feeding at the dose of 1 and 1.5 % of feed volume. The duration of the experience was 42 days. Morphological (total erythrocyte and leukocyte content) and biochemical (total protein and albumins in blood serum) blood indices of experimental group poultry were studied. It was found that the use of aspen cell juice as a biologically active additive in an amount of 1.5 % in the broiler chicken diet had had a positive effect on blood morphological and biochemical indices, which was characterized by a reliable increase in the level of total protein and albumins in blood serum and the tendency to increase hemoglobin concentration, total erythrocyte and leukocyte content.
