Influence of soybean oil and fermented algae soluble lipid complex on productivity and quality of laying hen eggs

The studies examined the effects of soybean oil and various doses of a watersoluble lipid complex in a standard diet consisting of corn, soybean meal, sunflower meal, wheat germ and bran, limestone, monocalcium phosphate, table salt, baking soda, L-lysine, choline chloride, DL-methionine, L-threonine, adsorbent, and a vitamin and mineral mixture. During the experiment, egg productivity, feed consumption, live weight, physiological condition and safety of the controlled livestock were monitored. The eggs obtained during the experiment were weighed, morphometric indicators were determined (egg mass, mass of albumen, yolk, shell and its thickness and strength, shape index, viscosity coefficient, pH of albumen and yolk, refractive index). The content of total lipids and vitamins A and E was determined in the egg yolk. As a result of the research, it was found that the egg-laying process in all experimental groups began at 115 days and at 140 days of age the productivity was 39,50–42,35 %. The peak of egg productivity occurred at 200 days and was 95,30–96,80 % and was maintained at a high level until 320 days of age (94,50–95,75 %). On average, for the entire period of the experiment, which lasted until the age of 450 days, egg production was 84,23–85,79 %. The highest productivity was in the III experimental group, which received 1,0–1,3 % of the fermented water-soluble lipid complex. Morphometric indicators of eggs in all experimental groups were approximately at the unit level and were within the normal range. At the age of the most intensive egg laying, the mass of eggs was 60,15–61,85 g. The highest mass of eggs was in the III and IV groups, which received 1,0–1,6 % of the fermented watersoluble lipid complex. During the experimental period, 15,97–17,09 kg of egg mass per head was obtained from laying hens. The content of total lipids, vitamins A and E was higher in the III experimental group, by 8,10; 5,81 and 10,71 %, respectively. The live weight of laying hens corresponded to the recommendations for keeping laying hens Loman LSL-classic. Therefore, adding a fermented water-soluble lipid complex instead of soybean oil is appropriate and economically beneficial, since its cost is 24 % lower.

Keywords: laying hens, egg production, morphometric indicators, soybean oil, water-soluble lipid complex, egg yolk, total lipids, vitamins A, E.
