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 |
