Abstract
Quails are a valuable type of poultry, as their eggs and meat have high nutritional value. Moreover, quails are distinguished by early sexual maturity, high egg production and small body size. These unique characteristics make them an attractive object for breeding and scientific research. The purpose of the study was to investigate the effect of feed with extruded components and phytobiotics on the meat productivity and blood biochemistry of Texas quails. The methodology involved dividing 200 quails into experimental and control groups, feeding them different diets over a 60-day period, and analysing their growth performance, meat yield, and biochemical blood parameters using statistical analysis tools. As a result of the research, it was revealed that feed produced according to the developed recipe has a positive effect on the weight gain of quails. In the experimental group (EG), the absolute increase was 313.7 ± 4.34 g, in the control group (CG) – 275.9 ± 2.89 g (not significant difference, P > 0.05). Furthermore, the feed with extruded components and phytobiotics led to improved feed conversion ratio in the EG compared to the control. The birds in the EG also demonstrated higher carcass weight and yield. The experimental diet also appeared to have a positive influence on the immune status of the quails. The results demonstrate the potential benefits of incorporating extruded components and phytobiotics into quail feed to improve growth performance and maintain healthy physiological parameters. Evaluating the biochemical blood test results, it can be indicated that no significant changes in the blood composition were detected, which may indicate the absence of a negative effect of the developed feed on the body of birds. The results obtained may be of practical importance for developing optimal diets for meat quails and improving the quality and safety of their products
