Meta-Analysis of Probiotic

A
meta-analysis was conducted to determine relationship between lactic acid
bacteria and yeast as probiotic to broiler diets on the growth performance,
relative organ weight, blood parameters, and immune response of the broiler. A database was designed based on published
data that reported the use of probiotic on the broiler. The method used for
selecting articles was based on the SYRCLE's method. The final database
consists of 49 in vivo articles, 93 studies, and 225 treatments. The analysis
statement in the system was a PROC MIXED procedure of SAS software. The level
of probiotic increased (p <0.001) body weight, body weight gain, and feed
intake of broiler. There was a reduction (p <0.01) on FCR and mortality on
the level probiotic given to broiler. Supplementation of probiotics in broiler
diet increased (p <0.001) the weight of liver, spleen, gizzard, bursa of
fabricius and carcass yield, while reduced (p<0.001) abdominal fat weight.
The probiotic given increased the total of red and white blood cells (both at p
< 0.001) but did not affect lymphocyte.
Yeast act as supporting agent that serve lactic acid bacteria as
probiotic increases the growth performance, relative organ weight, blood
parameters, and immune response of the broiler.
