Flax cake – an effective means of optimizing the protein feeding of poultry

Анотація

Cake is a by-product that is obtained after
the oil extraction from the oilseeds. Flax cake in
Ukraine is made in accordance with DSTU 8241: 2015
in the form of crushed or shell-shaped compressed
particles. The purpose of the work was to analyze
the chemical composition of flax cake and to prove
the feasibility of its use in feeding poultry. It has
been shown that the energy nutrition of flax cake is
as close as possible to soybean cake, and is almost
identical to that of crude protein. It is positively
distinguished from the sunflower cake by a lower
concentration of crude fiber more than three times.
Due to the inclusion of flax cake in the fodder poultry
feed, the diet may be adjusted according to the
ratio of fatty acids ω-3 to ω-6. Flax cake is a highly
nutritious source of vegetable protein with increased
digestibility in poultry. This is due to the significant
accumulation of essential amino acids and low
concentration of crude fiber in the product. Flax cake
can be included in the compound feed of the poultry,
starting with the pre-start diet. Poultry older than 2
weeks of age can be fed flax cake in the feed at a dose
of 3–5% by weight, and for 5-week old chickens and
older, up to 7% of this additive instead of sunflower
flakes and partially soybean cake.
