Effect of dietary hemp seed cake on the performance of commercial laying hens

The cultivation of hemp was prohibited due to its high content the psychoactive substance Δ-9 tetrahydrocannabinol (THC). Regulatory changes from several countries allow that permits plants and plant parts with less than 0.3% THC. concern levels THC still remains; therefore, testing seed cake (HSC) contributes new information about effect this ingredient on livestock. objective study evaluate HSC feed intake, body weight (BW), egg production, eggs per hen housed (EHH), conversion ratio (FCR), livability laying hens. Eight hundred 30-week old hens were randomly distributed fed four treatments for 19 weeks, no (C0), 10% (H10), 20% (H20) 30% (H30) replicated 8 times 25 replicate. Feed intake not affected by supplementation. BWs reduced across all significant lower impact treatments, EHH FCR consistently within normal range breed. results confirm supplementation in does affect performance Key words: Hemp, (HSC), performance, tetrahydrocannabinol, (THC), safety.&nbsp
