Abstract
The present experiment was conducted to study the effect of feeding yeast
(Saccharomyces cerevisiae) with phytobiotic (Thyme oil) on performance, blood
biochemical parameters, gut parameters, carcass traits, nutrient digestibility and
economics of Japanese quails. Two hundred and forty, day-old birds were randomly
distributed into 4 treatment groups; each treatment group having 4 replicates of 15
chicks. The dietary treatments were T0 (standard quail diet as per ICAR, 2013), T1 (T0 + thyme essential oil @ 450 mg/kg diet), T2 (T0 + yeast (Saccharomyces cerevisiae) @ 200 g/ ton) and T3 (T0 + thyme essential oil @ 450 mg/kg diet + yeast
(Saccharomyces cerevisiae) @ 200 g/ ton). At the end of the experiment i.e. 5th week, significantly higher (P<0.01)
body weight and feed efficiency (P<0.05) was recorded in treatment group T3 followed by treatment group T1, T2 and T0 (control group). However, body weight
gain and feed consumption were found to be non-significant in all treatment groups.
Blood biochemical parameters viz., total protein, albumin and globulin
were increased significantly and cholesterol and triglyceride were decreased (P<0.05)
in the treatment group T3. Carcass traits parameters like fasting body weight,
debleeding weight, defeathering weight and giblet percentage were found to be non
significant in all treatment groups whereas treatment group T3 showed significantly increased dressing percentage. Gut parameter study exhibited significant decrease in
ileal pH, E.coli and Salmonella count in treatment group T3; on the contrary, intestinal weight, length and thickness showed non-significant results. Similarly, there
was significant increase in dry matter digestibility and nitrogen retention in treatment
group T3.
It was concluded that supplementation of standard quail diet with thyme
oil and yeast Saccharomyces cerevisiae has beneficial effects on the performance of
Japanese quail. Moreover, it aids in procuring higher net profit per bird ultimately
leading towards a more profitable quail production.
