Metabolic effects in quails when applying horse chestnut tannin

The aim of research is to study the metabolic effects in quails when using horse chestnut tannin. The quails received a standard ration produced at OAO BKZ (open joint stock company). The experimental group of quails was fed with horse chestnut tannin at 25 mg per kilogram of live weight. On the last day of the experiment, venous blood was taken from the axillary vein from the quail into vacuum tubes. The blood was subjected to clinical biochemical analysis for the content of biochemical markers: substrates, minerals and enzymes. The analysis was carried out using diagnostic kits, methods recommended by the International Federation of Clinical Chemistry. The analysis was carried out on an automatic biochemical analyzer Hemm Well 2910 Combi (USA). The research results were subjected to mathematical analysis using the methods included in the Statistica 10 (64-bit) software package. Sample normality was assessed using the Shapiro-Wilk test. As a result of the study, the following positive effects were revealed: an improvement in the exchange of heme-containing proteins, which was expressed in a decrease in the level of serum iron by 24.8 %, and an increase in the production of total bilirubin by a factor of 2.1. This positive effect was confirmed by a decrease in the activity of alkaline phosphatase by 19 % and γ-GTP by 48.6 %. A positive effect was also noted, expressed in a decrease in cholinesterase activity by 12 %, which indicates a decrease in inflammatory processes in the small intestine of quail and an increase in α-amylase activity by 79.8 %, which indicates an improvement in the formation of digestive enzymes. There were also negative effects that were thought to be related to the anti-nutritional effects of horse chestnut tannin.
