Karma Nidup & Pema WangchukFigure 1: Typical growth rate of broiler at different age. Source: Lacy, 2001The actual live-weight gain (final live-weight – initial live-weight) in41 days for each SFG bird is 2.41 kg with daily weight gain of 58.76 gm.On the other hand, actual live-weight gain of each bird in KFG is 2.14kg with daily gain of 52.28 gm. This may be the fact that CP content ofSF is better than KF. The growth curve generated is very much in linewith schematic representation of growth curves for broiler chickenssuggested by Lesson & Summers (1991) as depicted in Figure 2.Figure 2: Schematic representational growth curves of broiler chickens.

Comparative Study of Broiler in BhutanGrowth rate of birds in both groups have taken a shape of line C (Figure3). Both groups had initially slow growth rate but accelerate at somepoint ( week 3) towards projected market weight of 2.0 kg in 42 days.Birds with growth rate of such trend are likely to exhibit a superior feedconversion since its maintenance requirement will be less (Leeson &Summers, 1991). The reason for this reduced maintenancerequirement is that at any specific age, prior to projected market weight,the birds had smaller body mass to maintain, and so will need less feednutrient for this purpose. However, such growth trend would meanincreased carcass fat composition, which was also true in thisexperiment.Figure 3: Growth curve of the KFG and SFG.The statistical analysis of Two-sample t-test for final market liveweightof KFG and SFG birds suggest that there is a significantdifference (P-Value = 0.000) between the groups at 95% confidenceinterval. In other words, SFG birds had significantly higher marketlive-weight than KFG birds. The box plot (Figure 4) generated below isan illustrative indication of the live-weight gain of KFG (KLWt) andSFG (SLWt).19
