Abstract
The extensive use of antibiotics growth promoters leads to residues and
bacterial resistance; therefore,
temulawak nanoemulsion (TN)
is expected to be a potential alternative as natural growth promoter (NGP) in
broiler chickens. This study was aimed to assess the effect of TN on broiler
chickens’ productivity, blood profile, and antibiotic resistance. A total of 72
one-day-old broiler chicks strain MB (Lohman 202) were reared for 35 days and
divided into four groups: negative control (without supplementation), positive
control (AGP 50 mg/L), and administration of TN 2 mg/kg and 4 mg/kg BW. Body
weight (BW), feed intake (FI), feed conversion ratio (FCR), and index
performance (IP) were calculated to evaluate broiler chicken’ productivity. On
day 35, blood and cloacal samples were collected for hematology and antibiotic
resistance tests. The data were analysed using SPSS software. The results showed
that supplementation of TN 4 mg/kg BW improved broiler chickens’ productivity
with efficient FI (P>0.05),
optimum FCR (P>0.05) during 30-34 days of trial, and the highest IP value. TN 4
mg/kg BW group also had the lowest increasing levels of WBC and eosinophil
compared to other groups, while PCV, RBC, and other leukocyte differential
levels were normal compared to standards (P>0.05).
Moreover, this group showed a decrease in the resistance rate to Amoxicillin and
Ceftriaxone compared to control and AGP treatment. It was concluded that TN 4
mg/kg BW could be used as NGP.
