The production of nonindustrial cannabis is highly developed in the Moroccan Rif region; however, local farmers consider hemp seeds which are rich in omega 3 and tocopherols, only as by-products of cannabis cultivation with low market value. The local ecotype is considered to be a plant with a cannabinoid content of more than 0.4%. So, the objective of this research is to investigate how the incorporation of this local hemp seed affects productive performance and egg quality traits. The experiment is conducted to evaluate the effects of hemp seed (HS) incorporation on hen laying performance and physical egg quality at three levels: 10% (HS-10% group), 20% (HS-20% group), and 30% (HS-30% group). Ninety-six Lohmann Brown classic laying hens were randomly assigned to a control group and three feed treatments. The sampling was taken after the 28-week rearing period (peak egg laying). Throughout the experiment, low-rate HS inclusion (HS-10%) showed no significant differences in egg-laying performance ( > 0.05). However, the high incorporation rates of HS (20% and 30%) negatively affected the egg-laying performance (84-94% and 80-86%, respectively). The albumen quality was also improved by the HS inclusion, where the highest values of the Haugh unit were recorded, ranging between 68.69 and 73.91 for the HS-30% groups. The results also show that HS inclusion and duration influence significantly the yolk color ( < 0.001). The yellow intensity decreases with HS incorporation and aging, from a dark yellow ( = 38.63 for the control group) to a very pale yellow ( = 26.29 for HS 30% group). Based on these findings, we can conclude that the incorporation of nonindustrial Moroccan cannabis seeds (ecotype ) at low rate in the diet of laying hens does not alter the laying performance or the quality of the egg; therefore, they could be used in poultry feeding as an alternative constituent to partially replace high-cost imported ingredients, such as corn and soybeans.
摩洛哥里夫地区非工业用大麻的种植十分发达；然而，当地农民仅将富含欧米伽3和生育酚的大麻籽视为大麻种植的低市场价值副产品。当地生态型被认为是一种大麻素含量超过0.4%的植物。因此，本研究的目的是调查这种当地大麻籽的掺入如何影响生产性能和蛋品质性状。进行该实验以评估大麻籽（HS）掺入对母鸡产蛋性能和蛋的物理品质的影响，设置三个水平：10%（HS - 10%组）、20%（HS -
20%组）和30%（HS - 30%组）。96只罗曼褐经典蛋鸡被随机分配到一个对照组和三种饲料处理组。在28周的饲养期（产蛋高峰期）后进行采样。在整个实验过程中，低比例掺入HS（HS - 10%）在产蛋性能方面没有显著差异（P＞0.05）。然而，高比例掺入HS（20%和30%）对产蛋性能有负面影响（分别为84 - 94%和80 - 86%）。HS的掺入也改善了蛋白品质，HS - 30%组的哈夫单位值最高，范围在68.69至73.91之间。结果还表明，HS的掺入和持续时间对蛋黄颜色有显著影响（P＜0.001）。随着HS的掺入和蛋的存放时间延长，黄色强度降低，从深黄色（对照组为38.63）变为非常浅黄色（HS 30%组为26.29）。基于这些发现，我们可以得出结论，在蛋鸡日粮中低比例掺入摩洛哥非工业用大麻籽（生态型）不会改变产蛋性能或蛋的品质；因此，它们可用于家禽饲养，作为部分替代高成本进口成分（如玉米和大豆）的替代成分。
