Use of protein concentrate “Agro-Matic” in feeding young chickens

Introduction. Problems and promising areas of the poultry farming industry are closely related to adequate poultry feeding. Feed accounts for up to 70% of the total cost structure. Therefore, today the search for alternative feed sources in poultry feeding that has better feed advantages and is characterized by low cost remains relevant. One of these is the protein concentrate “Agro-Matic”. In connection with the above, we studied the effect of the protein concentrate “Agro-Matic” in feed for young chickens on hematological parameters and the dynamics of live weight.
Materials and methods. Scientific and economic experiments on young chickens were carried out at the JSC Volzhskaya poultry farm in the Sredneakhtubinsky district of the Volgograd region. The Hisex Brown cross bird was selected into four similar groups, taking into account age, development, etc. There were 80 birds in each group (control and three experimental ones). The duration of the studies was 17 weeks. Throughout the entire experiment, young chickens in the control group received feed with full-fat soybeans. The birds of the I-, IIand III-experimental groups received feed in which full-fat soybean was partially or completely replaced by the Agro-Matic protein concentrate in the amount of 50%, 75% and 100%, respectively (of the weight of soybeans in the diet). The conditions for keeping and feeding poultry of all experimental groups were the same and complied with the recommendations of VNITIP.
Results and conclusions. At the end of the experiment, an increase in the live weight of pullets of the experimental groups was noted compared to the control group, so in experimental group I (1408.33 g) by 12.13 g, in experimental group II (1431.30 g) by 22.97 g, in the III experimental group (1440.04 g) – by 31.75 g. Based on the studies conducted, it should be noted that the hematological parameters in birds of all experimental groups were within the physiological norm. However, the birds of the I-, II- and III experimental groups, compared with the control group, tended to increase the content of erythrocytes by 8.01%, 9.70%, 10.97%, hemoglobin by 6.98%, 8. 12%, 8.53%, total protein by 2.69%, 3.05%, 3.54%, glucose by 2.73%, 3.12%, 3.52%, calcium by 6.64%, 11.80%, 15.13% phosphorus by 4.88%, 6.09%, 13.41% The observed trend in the blood of birds of the experimental groups indicates a greater intensity of metabolic processes in their body, compared with control analogues. Thus, partial and complete replacement of soybean with protein concentrate “Agro-Matic” in feed recipes had a positive effect on the hematological parameters and live weight of pullets.
