A study was conducted to establish the possibilities for replacing 5 and 10% of wheat in the combined feed for domestic quails with extruded bakery waste and to study its impact on the growth and productivity of quails. 270 domestic quails from the specialized meat production line WG were included in the experiment and divided according to the principle of analogues into 3 aligned groups: control, fed with mixtures without the inclusion of extruded waste from bakeries; experimental I, in the mixtures of which 5% of the wheat was replaced with extruded bakery waste and experimental II, in which 10% of the wheat in the mixtures was replaced by extruded bakery waste. The experiment continued until the age of 35 days. The following signs were monitored: mortality (%), live weight (g), average daily weight gain (g), feed consumption (g), feed conversion (kg/kg weight gain). The study showed that for the 35-day period, the quails from the specialized meat production line WG consumed an average of 812-817 g of compound feed, with an average increase of the weight gain 255-258 g. Under these conditions, the average feed conversion ratio is in the range of 3.15-3.20. In the course of the trial it was found that the replacement of 5 and 10% of wheat in the feed mixture with extruded bakery waste reduces the value of compound feed by an average of 0.85 and 1.7%, but does not affect the studied productivity traits and economic indicators from fattening. When summarizing the results for the 35-day period, the differences between the control and experimental groups on the studied productive traits are less than 2%, and the difference in the value of 1 kg weight gain between the groups is less than 1%. |
