Abstract
An experiment was conducted to evaluate the effect of incorporation of garlic
and ginger in diet of broiler birds. Two hundred forty cobb-400 broilers chicks were
randomly divided into four groups with three replications of twenty birds each. Each
group was assigned with one of the four dietary treatments (Ti, T2, T3 and T4) for a
period of 42 days. The experimental birds under control group Ti were fed as per BIS
(1992). While in group T2, group T3 and group T4 were additionally supplemented
with 1% garlic, 1% ginger and combination of 1% garlic and 1% ginger respectively,
with control diet.
Average initial and final body weights of birds of experiment were 40.10 ±
0.05 & 1646.68 ± 1.15, 40.00 ± 0.02 & 1689.32 ± 52.88, 40.02 ± 0.05 & 1758.89 ±
38.06 and 40.12 ± 0.16 & 1638.26 ± 59.01 g in the Ti, T2, T3 and T4 experimental
groups, respectively.
The average values for weekly body weight gain (g^ird/week) and total body
weight gain (g^ird) were 267.76 ± 8.62 and 1606.70 ± 1.83 in Ti, 274.88 ± 18.87 and
1649.17 ± 53.08 in T2, 286.20 ± 11.49 and 1724.17 ± 33.78 in T3 and 266.34 ± 10.64
and 1598.36 ± 59.26 in T4 experimental groups, respectively. The total weight gain
during the experiment was highest in T3 group followed by T2 group which differed
significantly (P < 0.05) from that of Ti and T4 group.
The values for overall feed intake were 3270.56 ± 54.48, 3259.12 ± 81.83,
3367.77 ± 136.43 and 3395.61 ± 155.74 g/bird in Ti, T2, T3 and T4 groups
respectively. The total feed intake during the experiment was highest in T4 followed
by T3 and Ti which significantly (P < 0.05) higher from the T2. The mean values for
PGR of broilers were found to be 1.92± 0.02, 1.87± 0.06, 1.84 ± 0.03 and 1.99 ± 0.01
in Ti, T2, T3 and T4 experimental groups, respectively. PGR showed non-significant
difference among different experimental groups.
The corresponding values of average dressing percentage were 65.66 ± 1.45,
67.00 ± 0.57, 65.33 ± 0.33 and 65.66 ± 0.33 in Ti, T2, T3 and T4 experimental groups,
respectively. There is significantly (P < 0.05) higher dressing percent in group T2 from
the Ti group. While dressing percent of T2, T3 and T4 groups are at par. Weights of
organs like heart, liver, intestine, gizzard and shank differ significantly (P < 0.05)
among experimental groups. Statistical analysis of sensory evaluation suggests that T3
group showed significant (P < 0.05) higher values for all parameters among different
treatment groups. Definite pattern in different parameter values also suggest that
ginger affect carcass quality positively.
