A meta-analysis was conducted to determine the effects of herbal plant extracts on growth performance, blood parameters, nutrient digestibility and carcase quality farmed rabbits. dataset created from 33 in vivo studies comprising 121 experimental units. Statistical performed using a random-effects model linear-mixed meta-regression R software (v. 4.3.0). Our results showed that although supplemental herbs did not affect average daily gain (ADG) final body weight (BW), they reduced (P <...

The legalization of industrial hemp by the 2018 Farm Bill in US has driven a sharp increase its cultivation, including for cannabinoid extraction. Spent biomass (SHB), produced from extraction cannabinoids, can potentially be used as feed dairy cows; however, it is still illegal to do so US, according FDA-CVM, due presence cannabinoids and lack data on effect animals. To assess safety this by-product cows, late-lactation Jersey cows (245 ± 37 DIM; 483 38 kg BW; 10 multiparous 8 primiparous)...
