“…Previous studies have con rmed that dietary lipid types do not affect egg production and egg weight (Abbasi et al 2019, Ceylan et al 2011. It was reported that egg yield, egg weight, and feed intake did not change with the inclusion of different lipid sources (cotton, corn, ax, soybean, olive, sun ower, sh, tallow, and rendering) in the diet (Balevi and Coskun 2000).…”

This study compared the effects of hemp seed oil versus four different UFA-rich seed oils in the diet of laying hens on egg production, quality, and fatty acid profile of the yolk. Soybean, sunflower, corn, canola, and hemp seed oils were included in the hens' diets in equal proportions. A total of one hundred and twenty 42-week old White Leghorn hens were placed in five diet groups with 8 replicates. The trial lasted 84 days and data were collected on egg production, quality, and fatty acid profile of the yolk. The data showed that none of the incorporated seed oils affected egg production or quality. However, hemp seed oil altered yolk colour values similarly to canola oil by increasing the L* value of the yolk while decreasing the a* value (P < 0.05). Hemp oil increased the PUFA content in the yolk, similar to soybean, corn, and sunflower oil, but unlike the latter, it also enriched the n-3 fatty acids in the yolk (P < 0.05). In conclusion, hemp seed oil can be safely used in the diet of chickens without having negative effects on egg production and quality like other seed oils. Furthermore, hemp seed oil can improve the desirable fatty acid content in the yolk and has the potential to produce n-3 design eggs.

The article presents experimental data on the influence of the feeding diet on the biochemical blood parameters of laying hens. As feed additives in the poultry diet were used: feed vitamin-mineral concentrate (FVMC) in the amount of 0.3% of the basic diet (BD) (1st experimental group), probiotic additive “Bacell-M” in the amount of 0.2% of BD (2nd experimental group), complex feed concentrate (CFC), containing FVMC and probiotic additive “Bacell-M”, in the amount of 0.3% of BD (3rd experimental group). The control group received only BD. It was found that the introduction of the feed additives into the diet of laying hens stimulated the metabolic processes in the poultry body, which was manifested by an increase in a number of biochemical constants. So, the level of total protein in the 1st experimental group increased by 34%, in the 2nd and 3rd experimental groups it increased in 1.43 and 1.42 times in comparison with the control group. The urea concentration exceeded the analogical values of the control poultry by 27% (1st experimental group), by 23.2% (2nd experimental group) and by 24.3% (3rd experimental group), respectively. The use of feed additives influenced the state of carbohydrate and lipid metabolism of hens, which was manifested by an increase in glucose concentration in the groups by 6.3%, 13.1% and 21.5% and by an increase of triglycerides by 13.2%, in 1.7 and in 2.0 times respectively. The inclusion of additives in the feeding schemes contributed to the correction of mineral metabolism, providing more complete absorption of calcium by the poultry, the increase of which in the experimental groups was by 16.2%, 1.68% and in 2.21 times, and also prevented the development of hepatocyte cytolysis, as indicated by a decrease in the activity of hepatoindicatory of enzymes: ALT decreased by 9.8%, 29.5% and in 1.85 times, AST decreased by 7.9%, 12.7% and 18.9%, respectively. The maximum positive effect in the indicators of the biochemical status of laying hens was observed when CFC was used in the diet, which was due to the synergy of FVMC and the Bacell-M probiotic additive.
