part of the data while some are exported to Minitab (version 13) forsimple statistical analysis.RESULTAND DISCUSSIONNutrient Content andAflatoxinPoultry feed contains all nutrients needed to grow muscles, bones,internal organs, fat and feathers.About 65-75% of the total expenditureof commercial poultry farming goes to feeding, therefore success ofpoultry farming depends mainly on use of balanced but cost effectivefeeds. Proteins, which are metabolized and converted into variousamino acids, are essential for chickens.Nutrient analysis revealed that KF starter has not met recommended orstandard crude protein requirement (Cheeke, 1999; Coon, 2001) by1.31% while SF starter contain 1.07% CP higher than actualrequirement (Table 1). In other words, latter contains 2.38% CP higherthan former. It is also evident from Figure 4 that performance of SFGhas taken new turn from day 14 to day 20 as CP requirement is highestin the first 2-3 weeks (Lacy, 2001). However, both SF and KF containslightly higher CP than the standard requirement (Table 1). Whencompared among the two feeds, SF contains 0.34 % CPhigher than KF.Table : Comparison of nutrients in two feed samples (analyzed at SPAL) as comparedto standard nutrient recommendation (Cheeke, 1999; Coon, 2001)SamratStarterKarma Nidup & Pema WangchukSamratFinisherStandardNutrientRequirement(Starter)16StandardNutrientRequirement(Finisher)KarmaStarterKarmaFinisherCrude Protein 24.07% 20.93% 23.00% 20.00% 21.69% 20.59%Crude Fiber 5.67% 6.61% 2.5% 2.4% 6.38% 7.02%Either extract 4.00% 5.85% 3.81% 3.13%Dry matter 90.09 91.31% 90.26 90.27%%Calcium 1.03% .90% 1.00% 0.90% 0.86% 0.75%Phosphorus 0.52% 0.49% 0.45% 0.40% 0.58% 0.47%Potassium 1.85% 0.60% 0.40% 0.35% 1.02% 1.22%Magnesium 0.03% 0.18% 600mg 600mg 0.04% 0.09%NDF 20.69%ADF 19.77%
