| Summary: | An experiment was conducted to evaluate the effect of various culture media used to
provide nutrients for lactic acid bacteria (LAB) on performance, carcass yield, blood
parameters, natural antibody titers, and lipid and protein metabolism namely plasma
triglycerides, total protein, albumin, and urea in broiler chickens. A total of 400 one-dayold
Cobb broiler chicks was allocated to four treatments: a control feed (no probiotics),
feed supplemented with 2% probiotic powder, which had been cultured in one of the
following media: (1) 100% cow milk (CM), (2) a mixture of 50% cow milk and 50%
soybean milk (SM), or (3) a combination of 50% cow milk, 25% soybean milk, and 25%
mung bean milk (MM), reared for 28 days of experimental period. The results showed
that, birds fed SM exhibited higher body weight, body weight gain, feed intake, and better
feed conversion ratio than other groups, as well as higher carcass percentages, lower
abdominal fat, and lower plasma and meat cholesterol. They also showed significantly
lower plasma triglyceride, total protein, and albumin levels (P<0.01) and reduced IgY
and IgM antibody titers binding keyhole limpet hemocyanin (KLH). Nonetheless,
all treatments demonstrated an increasing immune response over time. These data
indicate that a 50:50 cow milk and soybean milk probiotic culture could enhance broiler
performance, carcass yield, plasma lipid metabolism, blood metabolite profiles (such as
protein, albumin, and urea) and immune status. |
