摘要

The effects of stocking densities of 30, 35, 40 and 45 kg body weight (BW)/m2 on the growth performance of Ross 308 and Hubbard broiler chickens were studied in a 49-day production period. Ross 308 was superior to Hubbard in weight gain and market weight and consumed more feed (p<0.05) but the strains did not differ significantly in feed efficiency, mortality rate and abdominal fatness. Overall, birds raised at stocking densities of 30, 35 and 40 kg BW/m2 performed equally well in weight gain, feed consumption and 49-day live weight and outperformed those raised at 45 kg BW/m2 (p<0.05). It is suggested that for profitable broiler production under tropical conditions Ross 308 and stocking density of 40 kg BW/m2 be considered.Digital Object Identifier http://dx.doi.org/10.1007/s11250-011-9907-0
