Karma Nidup & Pema WangchukFigure 4: Comparison of final live weight between KFG and SFG.In addition to this, the carcass-weight of both the categories of birdswas compared. The SFG birds had significantly higher (P
while KFG birds had eaten 2.65 kg of feed to gain 1 kg live-weight.This suggests that animals that have low FCR are considered efficientusers of feed. In fact, FCR was better than the standard value suggestedby Saxena (1999). The ideal environmental temperature, good housingconditions (air quality, litter management), and aflatoxin free feedsmay have been the reasons for good feed efficiency.Since two categories of feeds were used, FCR alone cannot reveal theefficiency of feed. It is also important to calculate the cost effectivenessof feed used. The total feed consumed in six weeks by 94 birds in SFGis 465.25 kg costing Nu. 6112.21. On other hand, total feed consumedby KFG was 532.99 kg of feed costing Nu. 6350.11. Both from thepoint of FCR and cost effectiveness of feed, SF has proven to be betterthan KF. Although, it is not clear how Vencobb broiler birds have beenbred, the genetic potential of this strain to convert feed into meat maybe another factor contributing to good feed efficiency. There has beensteady genetic progress in growth rate of broilers over the last twodecades (Nicholson, 1998).CONCLUSIONSComparative Study of Broiler in BhutanThe performance of broiler birds fed with imported feed was betterthan the feed manufactured in Bhutan. It was justifiable for privatebroilers farms or any other broiler farms in Bhutan to import feed fromIndia. However, this experiment does not indicate that KF is a poorquality feed. In fact, it has achieved 2.14 kg live-weight and this ishighly acceptable market live-weight at 42 days. To further improveKF, the study recommends following:There is a need to increase CP content of in-country broiler starterfeed (at least up to 23% CP).Physical form (particle size) of feed needs improvement if KF is toattract customers within and outside Bhutan. Studies have shownthat feeding pellets made into crumbs as starter diet, and pellets asfinisher diet significantly increases live-weight and improves feedefficiency (Yule, 1974; Saxena, 1999; Coon, 2001).To further substantiate this experiment, similar studies with21
