2006 m. Nr. 4 Influence of a prebiotic feed additive on some
biochemical indices of blood and intestinal
microbiota of broiler chickens
Investigations were carried out in 2005 at the Research Laboratory of Biological Diversity and Technologies of Vilnius Pedagogical University and on the poultry farm “Petkus”. The object of the study was chicken broilers divided into two groups (control and trial) each containing 100 day-old chickens (50 male and 50 female). Chickens were fed dry standard feed of the same composition and nutritional value in both groups, but to the feed of the trial group the prebiotic feed additive BIO-MOS was added. The dosage of the prebiotic additive was different at various periods of age of the chickens: 0–7 d. (2 kg/t feed), 7–35 d. (1 kg/t feed) and at 35–39 d. (0.5 kg/t feed).
The blood of the chickens at the age of 21 and 39 days was examined by the colorimetric method for total proteins and total nucleic acids. Serum protein fractions were investigated by electroforesis. Microbiological investigations of the intestinal content were carried out by standard methods. Results of our study showed that in the trial group the total amount of nucleoacids in the blood of male chickens increased by 26.34% (P < 0.01) at 21 days of age in comparison with the control group. Total proteins in the serum of male and female chickens of the trial groups increased by 3% during all the trial period in comparison with the control group. The level of globulins in the serum of the trial group male chickens at the age of 21 and 39 days increased by 2.3% and 3.3% and in the serum of female chickens by 1.30% and 1% in comparison with the control group. Analysis of different fractions of serum globulins showed that in the serum of the trial group chickens the content of γ fraction globulins was by 2.42% higher in comparison with the control group. A positive effect on the population of „beneficial“ bacteria in the intestinal tract of chickens from the trial group was stated after the microbiological analysis of their gut content. Addition of the prebiotic BIO-MOS to the feed had a positive influence on some biochemical indices of blood which are important for a good immunity and growth of chicken broilers.
