Effect of substitution of soybean meal with canola and sunflower meals on the performance of broilers

摘要

A study was conducted to determine the effect of replacement of soybean meal (SBM) with locally available oilseed meals i.e. Canola (CM) and Sunflower meal (SFM) on performance of broiler chicks. Five different experimental rations A, B, C, D and Econtaining SBM 15 percent. SBM and CM 7.5 percent each. CM 15 percent. SBM 7.5 percent plus 3.75 percent CM and SFM each and SFM 15 percent respectively, were offered to the day-old broiler chicks up to six weeks of age. The effect of different rationswas observed in terms of the performance parameters of broiler chicks. The results showed that the weight gain. feed consumption, feed conversion ratio, carcass weight and dressing percentage were comparatively improved (P<0.05) where SBM was used as a source of vegetable protein. However. CM and SFM could successfully replace 50 percent of SBM. The 100 percent substitution of SBM with SFM resulted in high feed consumption with poor weight gain, feed conversion ratio, carcass weight, dressing percentageand liver enlargement, which could be attributed to comparative poor nutritional value and mycotoxin sesceptibility of SFM.
