Abstract
Effects of Long-Term Supplementation of Different Levels of Tannins Extract on Meat Quality and Carcass Traits of Hairy Lambs
Highlights
Tannins are a complex group of polyphenolic compounds found in many plant species commonly consumed by ruminants
Even when tannins be toxic when it consumes at high concentrations, at moderate level of intake has been shown benefits on growth performance and/or dietary energy utilization in cattle (Rivera-Méndez et al, 2016) and lambs (RojasRomán et al, 2017)
It has been reported that the period of supplementation can determine the magnitude of the effects of tannins supplementation (Rojas-Román et al, 2017); the aim of the present study was to investigate the dietary supplementation of a different levels (4 and 6 g tannins extract (TAN)/kg diet DM) concentrate source of hydrolysable and condensed tannins on meat quality of hairy lamb finished with a high-energy diet during 70 days
Summary
Abstract | Forty male hairy lambs (1⁄4 Pelibuey and 3⁄4 Katahdin, 31.53 ± 3.8 kg initial LW) were fed during 70 days with total mixed ration corn-based finishing diet supplemented with 0, 2, 4, or 6 g tannins extract/kg dietary dry matter (Control, TAN2, TAN4, and TAN6, respectively) in order to evaluate the effects of long-term tannin supplementation on meat quality. It is concluded that longterm supplementation of tannins may affect color and tenderness of meat lamb when is supplemented beyond 4 g/kg DM. Further research must be performed in order to establish the maximum dose level of supplementation with positive effects on meat quality but without detrimental effects of tannins on feed intake, nutrient utilization and health.
