The use of domestic enzymes in compound feeds for ducklings

The digestive system of farm animals and birds contains a small amount of enzymes that are necessary for the digestion of fiber and non-starchy polysaccharides that are part of the feed. To increase the efficiency of using plant feeds, especially during early weaning and intensive rearing of young animals, experts recommend adding complex enzymes to animal and bird feeds. The research topic is relevant, since the use of enzymes in compound feeds for ducklings is currently insufficiently studied. The aim of our work was to study the feasibility of including a mixture of enzymes of domestic production in compound feeds for ducklings and their impact on growth, development and meat productivity. The study was carried out on ducklings of the “Agidel” cross. Three groups of ducklings of 50 heads each at the age of one day were formed. The duration of the study was 63 days. Enzymes were not included in the feed for the experimental ducklings of the control group. Ducklings of experimental group I received a mixture of amylosubtilin G3x + protosubtilin G3x enzymes together with feed, and young ducks of experimental group II received a mixture of amylosubtilin G3x + cellulux-F enzymes. The live weight of ducklings at the beginning of the study was the same - 0.052 kg. By the end of the study, the live weight of the experimental ducklings varied: ducklings of the control group weighed an average of 3.424 kg, ducklings of the first experimental group - 3.712 kg, ducklings of the second experimental group - 3.804 kg. In experimental ducklings, when a mixture of enzymes was included in the composition of compound feeds, exterior measurements and, accordingly, body indices increased. In terms of slaughter qualities, the ratio of edible and inedible parts, ducklings of the second experimental group were superior to representatives of other groups. Thus, the use of a mixture of domestic enzymes in feeding ducklings had a beneficial effect on growth, development and meat productivity.
