Dietary inclusion of tannin extract from red quebracho trees (Schinopsis spp.) in the rabbit meat production

Two levels (1% and 3%) of condensed tannin extract from red quebracho (QT) were added to a diet of growing rabbits in a 6-wk feeding trial up to 12 wk of age. Health status was unaf- fected by the QT supplementation. The E. coli count of caecal content denoted a bactericidal activity of the QT. Weig...

Description
Summary:Two levels (1% and 3%) of condensed tannin extract from red quebracho (QT) were added to a diet of growing rabbits in a 6-wk feeding trial up to 12 wk of age. Health status was unaf- fected by the QT supplementation. The E. coli count of caecal content denoted a bactericidal activity of the QT. Weight gain and slaughter weigh were significantly higher and conversion index was sig- nificantly lower in rabbits fed QT diets, compared to those fed the control diet (P<0.05). Meat traits, as well the meat fatty acid profile weren&rsquo;t influenced by the QT supplementation. Our results contributed to increase the knowledge on the dietary use of QT in the rabbit. QT extract supplemented at 1% and 3% in fattening rabbits diet had a clear beneficial effect on live performance. Further studies are needed to assess if supplementing diets with QT can be a valuable strategy.
