“…Some studies have shown that the inclusion of natural sources of polyphenols such as CTs in the diet of small ruminants improves productive variables, preserves the quality of the meat, prolongs shelf life, and prevents deterioration (Dawson et al, 2011;Elmer et al, 2017;Mkhize et al, 2018).

Therefore, the objective of this study was to determine the fattening performance and characteristics of the lambs supplemented with CTs from the extract of Acacia mearnsii (EAM).…”
