THE USE OF UNCONVENTIONAL PROTEIN FEED FOR FATTENING BROILER DUCKLINGS
Abstract
The article presents the results of research on the possibility of using unconventional protein feeds, such as canola and camelina meal, in feeding ducklings of the Blagovarsky cross with broiler fattening technology. It was found that the inclusion of 5% of camelina meal in the compound feed instead of sunflower meal does not have a negative effect on the growth rate of young birds, their livability, slaughter yield and feed conversion. It is not considered rational to increase camelina meal, instead of sunflower one, in the content up to 10%, since it is accompanied by a decrease of the European Efficiency Factor by 8.9% due to a decrease in meat productivity and the livability of ducklings by 3.7 and 6.7%. The inclusion of 5% canola meal instead of sunflower led to an increase in the live weight of ducklings in the first and second half of fattening by 2.8 and 3.4% (P < 0.05) in comparison with the control. The inclusion of 10% canola meal contributed to obtaining a higher live weight of young birds at the age of 21 days and at the end of fattening by 3.8 and 4.5% (P < 0.05), compared with the control. Replacing 5 and 10% of sunflower meal with a similar amount of canola meal in duckling feed resulted in an increase of the European Efficiency Factor by 8.3 and 12.8%, which increased the profitability of meat production by 4.9 and 8.0%.
