Summary

   This study investigated the in vivo effects of two mixtures of herbal compounds on
growth performance of broiler chickens. 240 male broiler chicks (Ross-308) were
provided by PINDOS SA hatchery and were raised throughout the study period on
used litter, allocated into three treatments (8 pens of 10 chicks per treatment). Litter
was kept from a former study and all chickens were supplemented with a 5-fold cocci
vaccine EVANT®, HIPRA, on first day of treatments to get a mild challenge. All
chicks were vaccinated on hatchery against infectious bronchitis, Newcastle disease
and Gumboro. The CONTROL treatment was fed using commercial diets (starter,
grower, finisher) based on corn and soybean meal without antibiotics or anticoccidials.
The second treatment (HERB1) and third treatment (HERB2) received the same diets.
However, water in second and third groups was further supplemented with the herbal
mixture 1 and 2, respectively. Herbal mixtures contained garlic essential oil and other
phytochemical compounds and were administered at the level of 1 mg/lt of drinking
water. Total phenolic content of HERB1 and HERB2 test compounds was found to be
100 and 200 mg of gallic acid equivalents (GAE), respectively. Feed and water were
offered to the birds ad libitum. Temperature, moisture and air speed were monitored
throughout the trial. At the end of the trial (day 28), all birds were slaughtered, and
meat was examined for chemical composition. The HERB2 treatment had improved
(P<0.05) final body weight compared to both CONTROL and HERB1 groups (1280 g
vs 1226 g and 1217 g, respectively). Water intake also differed between the group,
since HERB2 treatment had higher (P<0.05) water intake compared to both
CONTROL and HERB1 groups (3611.6 g vs 3472.5 g and 3447.8 g, respectively).

Feed conversion ratio was better in HERB1 group (1.117) compared to HERB2 and
CONTROL groups (1.515 and 1.567). Chemical composition of breast and thigh meat
did not differ between the experimental groups. According to the results, the use of the
herbal products in the drinking water supported growth of chickens raised in an old
litter without antibiotic or anticoccidial drugs. Further studies could elucidate the
potential effects of the examined substances, as well as the underlying synergistic or
antagonistic mechanisms with feed constituents that may affect digestion and
absorption throughout the intestinal tract or the intestinal microbiota.
