Abstract
This article presents data on the use of feed additives in the diet of laying hens based on a 55 %
water-oil emulsion of fish oil and flaxseed oil, produced by Firm A-BIO LLC, Moscow. The experimental
part of the work was carried out in the vivarium of the Department of Parasitology
and Veterinary and Sanitary Expertise, in the experiment we used laying hens at 120 days of age
purchased from Mayskie Prostori LLC, the birds were kept in a three-tier cage with six heads per
tier, fed and watered freely, used PK1 compound feed for breeding laying hens 21–47 weeks in accordance
with GOST 18221-98.
The use of feed additives based on a 55 % water-oil emulsion of fish oil and flaxseed oil in the diet
of laying hens contributed to an increase in the amount of essential amino acids in the first experimental
group by 1.02 % and in the second, experimental group by 0,72 %, essential amino acids by
2,0 % in the first experimental group and by 1,7 % in the second experimental group in relation to
the control.
We noted an increase in the weight of one egg in the experimental groups in the first experimental
group by 5,2 % and in the second experimental group by 3,5 % relative to the control group; we
also noted an increase in the weight of eggs without shell in the first experimental group by 4,3 %
and in the second experimental group by 4,7 % compared to the control.
According to the results of the tasting assessment of eggs, we did not notice any foreign odor or
taste in chicken eggs that were fed with a water-oil emulsion of fish oil; according to the tasting assessment,
eggs from all groups were rated on a 5,0 point scale.
