ABSTRACT
Akbari SM, Rahimian Y.,
Effect of Glycyrrhiza glabra
(licorice) supplement on performance of Ross 308 broiler chicks, Onl J Vet Res., 21(7):387-392, 2017. Groups of day old 25
birds each were fed 42 days with basal diets of corn and soybean meal as
controls and basal diet with 200 or 400gr/ton Glycyrrhiza glabra licorice powder.
Feed intake, body weight gain and feed conversion ratios were determined
weekly. At day 42, four chicks from each group were slaughtered for carcass
evaluation. Blood cholesterol, triglycerides, HDL, LDL and Newcastle antibody were measured. Digesta
was used to determine Escherichia coli
and lactobacillus populations. Compared with controls, findings
suggested that body weight, feed to gain ratios, liver weight, blood and
antibody titers may have been affected by the supplement of licorice powder
(p<0.05). However, there were no effects on drumstick and breast meat
percentages. Glycyrrhiza glabra
licorice powder supplement in basal
diet may have reduced intestinal Escherichia coli but increased lactobacillus
compared with controls (p<0.05).
Key words: Blood biochemical,
Broiler chicks, Carcass traits, Licorice, Performance.
