The present study evaluated the effect of a commercial product containing Scutellaria baiacalensis (SB) extract administered as a top dressing in the feedbunk during 160 d (beginning of the fattening period to slaughter) as supplemental antioxidant on intake, health, vitamin E status and growth performances of Charolaise beef cattle. A total of 143 male cattle were allotted into 12 pens of 11-12 animals each. The pens were assigned to one of 2 dietary treatments: control (463.9±21.48 kg body weight; BW) and treated (469.8±17.91 kg BW) in which 20 g SB/animal/d was added. Each thesis was replicated in 2 subgroups of 3 pens. Feed intake was measured monthly on a pen base by difference between the amount of feed delivered and orts of 2 consecutive d. The total mixed ration (1 kg) was sampled for each pen and pooled by subgroup for chemical analysis. The correspondent pooled faecal samples were collected and analysed to monitor digestibility. Blood samples were collected at the beginning of the trial and at slaughter for individual α-Tocopherol and metabolic profile determination (total protein, albumin, globulin, urea, NEFA, glucose, total cholesterol, triglycerides, AST-GOT, GGT, bilirubin, creatine kinase, Ca, P, Mg, BHBA). Final BW at slaughter (BWS) and carcass weight were measured individually to calculate carcass yield, average daily gain (ADG) and feed conversion ratio (FCR). Overall, no differences in digestibility were observed during the whole experiment. The dietary SB inclusion did not affect feed intake, growth performances, BWS, ADG, FCR, blood α-Tocopherol or metabolic profile. These findings suggest that the supplemental doses of SB do not exert a negative impact on diet palatability and animal health. The present research was funded with the support of EU Horizon 2020 under grant agreement N° 774340 (OrganicPlus project).

Abstract
The present study evaluated the effect of a commercial product containing Scutellaria baiacalensis (SB) extract administered as a top dressing in the feedbunk during 160 d (beginning of the fattening period to slaughter) as supplemental antioxidant on intake, health, vitamin E status and growth performances of Charolaise beef cattle. A total of 143 male cattle were allotted into 12 pens of 11-12 animals each. The pens were assigned to one of 2 dietary treatments: control (463.9±21.48 kg body weight; BW) and treated (469.8±17.91 kg BW) in which 20 g SB/animal/d was added. Each thesis was replicated in 2 subgroups of 3 pens. Feed intake was measured monthly on a pen base by difference between the amount of feed delivered and orts of 2 consecutive d. The total mixed ration (1 kg) was sampled for each pen and pooled by subgroup for chemical analysis. The correspondent pooled faecal samples were collected and analysed to monitor digestibility. Blood samples were collected at the beginning of the trial and at slaughter for individual α-Tocopherol and metabolic profile determination (total protein, albumin, globulin, urea, NEFA, glucose, total cholesterol, triglycerides, AST-GOT, GGT, bilirubin, creatine kinase, Ca, P, Mg, BHBA). Final BW at slaughter (BWS) and carcass weight were measured individually to calculate carcass yield, average daily gain (ADG) and feed conversion ratio (FCR). Overall, no differences in digestibility were observed during the whole experiment. The dietary SB inclusion did not affect feed intake, growth performances, BWS, ADG, FCR, blood α-Tocopherol or metabolic profile. These findings suggest that the supplemental doses of SB do not exert a negative impact on diet palatability and animal health.
