The effect of different feed forms on the performance and carcass yield of broiler chickens

The aim of the research was to prove that the different feed forms affects the performance and carcass production. In total 240 New Lohmann MB 202 day-old chickens were randomly divided into five groups of treatment for 35 days of rearing period. There were 6 replications with 8 birds per pen. The chickens were fed starter feed at 1-21 days and finisher feed at 22-35 days with different feed forms: mash-mash (MM), mash-crumble (MC), mash-pellet (MP), crumble-crumble (CC), and crumble-pellet (CP). The data were obtained and statistically analyzed by ANOVA, then followed by Duncan's New Multiple Range Test. Feed form did not give any effect to feed consumption and weight gain but it affected feed conversion (P>0.05). MP kept the highest rate of feed conversion by the end of rearing period. Carcass yield showed that various feed form on days 0-21 did not affect carcass percentage of broiler chickens. The birds which ate pelleted feed on days 22-35 have higher (P>0.05) carcass weight than those consumed mashed and crumbled feeds. It is concluded that chicken fed with mash-pellet feed had the best feed conversion. Besides, the birds which ate pelleted feed on days 22-35 had highest carcass weight. © Published under licence by IOP Publishing Ltd.
