Abstract


It was evaluated the effect of adding Salix babylonica L. extracts and exogenous enzymes in
combination or individually on meat quality in growing Suffolk lambs. Animals were divided into 4
groups of 4 animals each in a completely randomized design (CRD). Treatments were: (i) Control: basal
diet of concentrate (30%) mixture and corn silage roughage (70%); (ii) EZE (exogenous enzymes): basal
diet plus 10 g of enzyme (Zado®); (iii) SB (Salix babylonica): basal diet plus 30 ml of S babylonica
extracts, and (iv) EZESB (exogenous enzymes + Salix babylonica): basal diet plus 10 g enzyme and 30
ml of S. Babylonica extracts. Lambs were housed in individual cages for 60 days. Extracts were dosed
orally while EZE was mixed with concentrate. At the end of the trial, lambs were slaughtered and
Longissimus dorsi samples were analysed. Samples were analysed for CP, CF, ash and DM. Meat
quality parameters included color, pH, carcass temperature and kidney fat. No significant differences for
live weight, chemical composition, as well as hot carcass weight and cold, initial and final temperature
and kideny fat. Meat lightness (variable L *) and pHf were improved (P<0.05) with EZESB treatment
compared to the other three treatments, and the most optimal pHf four treatments being the most acidic.
Lambs fed SB or EZE were not different from the control. In conclusion, a combined administration of
EZESB to the basal diet improves meat quality by reducing the pH and increasing its lightness when
compared to either EZE or SB, individually.
