EFFECTS OF GRADUAL FEED DILUTION WITH INERT OR LESS NUTRITIVE MATERIALS ON GROWTH PERFORMANCE, FEED COST AND MEAT ORGANOLEPTIC PROPERTIES OF BROILER CHICKEN

ABSTRACT The objective of the present study was to determine the effects of the gradual dilution of broiler finisher diets with inert or less nutritive materials on growth performance, feed cost, and meat organoleptic properties. Broiler chicks (n=147) were allocated into 49 pens and fed a mash broi... Full description

description: ABSTRACT The objective of the present study was to determine the effects of the gradual dilution of broiler finisher diets with inert or less nutritive materials on growth performance, feed cost, and meat organoleptic properties. Broiler chicks (n=147) were allocated into 49 pens and fed a mash broiler finisher diet (control) or the control diet diluted either with cassava leaf meal (CLM), gliricidia leaf meal (GLM), grass meal (GM), rice bran (RB), sand (SND), or sawdust (SD). For a given diluent, six diets were prepared by mixing the control diet with the respective diluents (w/w) at 0% (fed from 27-28d),2% (fed from 29-30d), 4% (fed from 31-32d), 6% (fed from 33-34d), 8% (fed from 35-36d) and 10% (fed from 37-40d). SD, RB, GLM and GM significantly reduced the diluent-adjusted feed intake (total feed intake-diluent intake). Except for GLM and SD, other diluents resulted in similar weight gains as the control diet. The dietary dilution with rice bran reported the best feed conversion ratio (FCR) (1.91). The total feed cost of the birds fed control and sand diluted diet was higher (p< 0.001) than those fed other diets. Compared with the control diet, the gradual dilution of feed with RB and SND reduced the feed cost per kg of live weight gain by 12 and 10 Rs, respectively. Meat organoleptic properties of the birds fed RB diluted diet were similar to those of the control birds. It was concluded that gradual feed dilution with inert or less nutritive materials could be used as an alternative to conventional phase feeding. Among the tested materials, rice bran was identified as the best candidate for such gradual feed dilution programs.
