This work was conducted to ensure that the consumption of a small amount of a chestnut
hydrolysable tannin (HT) extract, included in the diet (20.8 g·kg–1 DM) of finishing lambs as a feed
additive, does not cause toxic effects or does not negatively affect lamb performance. Thirteen
Merino lambs were finished from 15 to 25 kg of live weight, which is the most typical slaughter
weight for lambs in Spain. They were divided into two groups: one was used as the control (Control)
and the other one received the treatment with tannins (TAN). The only difference between the
groups was that the soya bean meal incorporated as the protein supplement in the TAN concentrate
had been treated with the chestnut HT extract. No significant differences (P > 0.10) in voluntary
intake, feed conversion, daily gain or length of fattening period were observed between the two
groups. The histopathological examination showed no signs of toxicity due to the tannins. Likewise,
the carcasses of the TAN group did not show residues of analysed HT metabolites (gallic acid,
ellagic acid, resorcinol, pyrogallol and phloroglucinol). The raised activities of the enzymes GGT
(gamma glutamyl-transferase) and AST (aspartate amino-transferase) in the TAN lambs suggest that
experiments of longer duration need to be conducted, to further check for toxicity effects under
these conditions. |
