Blood indicators of quails when protein supplements are used in feeding

The conducted studies of the chemical composition of soybean and lupine seeds feed additives showed that the total amount of protein in the samples was 38.4 and 32.6%, respectively. The crude fat content of extruded soybean (ES) seeds was 39.5% higher than in extruded lupine (EL) seed samples. The level of crude starch prevailed in EL seeds almost 2 times. Further, in the experiment on quails, 2 groups of Texas breed birds of 25 heads each were formed. The first (control) group received ES in addition to the main diet, the second experimental group was given EL instead of soy with an equivalent amount of protein as an alternative source to replace expensive and imported soy. Feeding EL contributed to the enhancement of hematopoiesis, the hemoglobin and hematocrit indices at the end of the experiment were 9.8% and 21.8% higher than in ES. By the end of the experiment, the total protein index in the EL groups was 5.0% higher than in the control. The activity of liver enzymes: ALP and AST were 16.2% and 20.4% lower than in the control. At the same time, the ALT level in both groups was within 14.22-14.26 unit/l, which indicates normal functional activity of the liver. It should be noted that despite the lower content of crude protein and fat, the lupine feed additive did not have a negative effect on the physiological status of the birds and can be used as an alternative source of vegetable protein in the diet for quails.
