Abstract
An experiment was conducted to evaluate the effects of thyme dried leaves
(TL), thyme extracted oil (TO) at two levels of each, and antibiotic (Lincomycin
Hydrochloride, AB) incorporated to broiler diets on growth performance, carcass
characteristics as well as bacteria enumeration, blood serum parameters and economic
efficiency. One hundred and eighty unsexed one day old of age Hubbard chicks were
weighed and randomly allocated into 6 treatments of 30 chicks in three replicates. The
experimental diets were as follows; basal diet without supplementation (control, TR1R), 1.5 g
TL/kg (TR2R), 3.0g TL/kg (TR3R), 125 mg TO/kg (TR4R), 250 mg TO/kg (TR5R) and 1.0g AB/kg
(TR6R). The main results obtained can be summarized as follows: Chicks fed basal diets
supplemented with TO (TR5R) or AB (TR6R) recorded an equal growth performance to chicks
fed the control diet. However, they recorded significant lower values of feed conversion
ratio. Carcass characteristics were non-significantly different for all treatment groups
except abdominal fat % and thymus %. Blood parameters showed insignificant figures in
most parameters. However, the addition of TO (TR5R) or TL (TR3R) has a significant effect on
total plasma albumin or ALT concentration.
