This research investigated the effects of adding nonindustrial hemp seed to the diets of laying hens over a four-month period. Ninety-six Lohmann Brown classic hens were divided into four feeding groups receiving either a standard control diet or diets supplemented with 10 percent, 20 percent, or 30 percent hemp seed. The results revealed that dietary hemp seed substantially altered the nutritional qualities of the egg yolk. Specifically, feeding hens higher levels of hemp seed, particularly at the 30 percent inclusion rate, significantly raised the levels of omega-3 and omega-6 polyunsaturated fatty acids while lowering the omega-6 to omega-3 ratio. Total tocopherol content in the yolk also rose significantly by day 84. In contrast, the cholesterol content of the egg yolk was not affected by the dietary additions.
Consumers and food producers increasingly seek practical ways to boost the nutritional value of everyday foods. This study shows that incorporating nonindustrial hemp seed into poultry feed enhances beneficial fatty acids and vitamin compounds in eggs without altering cholesterol levels, presenting a straightforward dietary approach to producing more nutrient-dense eggs.
This work is an applied animal feeding trial relevant to animal feed manufacturers and poultry farmers looking to produce enriched functional food products. By demonstrating that hemp seed can serve as an effective poultry feed ingredient to enhance egg nutritional value, it presents a potential formulation strategy, though commercial deployment would require evaluating local regulatory approvals and supply-chain costs.

The purpose of this study was to evaluate how cannabis-derived nonindustrial hemp seed (HS) inclusion in laying hen diets, as well as treatment duration, affected the fatty acid (FA) profile, cholesterol level, and tocopherol composition of egg yolks. Ninety-six ( <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" id="M1"> <a:mi>n</a:mi> <a:mo>=</a:mo> <a:mn>96</a:mn> </a:math> ) Lohmann Brown classic laying hens were randomly assigned to one of the four groups: control (standard diet) and HS-containing diets (10% HS, 20% HS, and 30% HS). The study was conducted for a period of 4 months. The findings demonstrated that the FA profile and the tocopherol composition are strongly impacted by the addition of HS to the diet of laying hens ( <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" id="M2"> <c:mi>p</c:mi> <c:mo><</c:mo> <c:mn>0.05</c:mn> </c:math> ), but the cholesterol content remained unaffected. The increase in the dose of cannabis incorporated into the hen’s diet (HS-30% group) led to a significant increase in the amounts of the polyunsaturated fatty acids n-3 and n-6 content of egg yolk. This enrichment was accompanied by a considerable decrease in the n-6/n-3 ratio ( <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" id="M3"> <e:mi>p</e:mi> <e:mo><</e:mo> <e:mn>0.001</e:mn> </e:math> ) from 8.19 to 4.88, on day 84 of the experiment. The total tocopherol content significantly increased ( <g:math xmlns:g="http://www.w3.org/1998/Math/MathML" id="M4"> <g:mi>p</g:mi> <g:mo><</g:mo> <g:mn>0.05</g:mn> </g:math> ) from 281.44 (control) to 327.02 μg/g yolk (HS-30%) on day 84. Finally, in the context of warfare, these seeds might be used as a feed additive for laying hens to produce higher nutritive value eggs with affordable prices.
