Influence of rearing system on growth performance, carcass traits, and meat quality of Yangzhou geese

ABSTRACT An experiment was conducted using a total of 540 one-day-old Yangzhou geese to study the effect of rearing system on growth performance, carcass traits, and meat quality of male and female Yangzhou geese. The birds were divided into homogeneous groups according to initial BW and sex. The male and female geese were raised in separate pens under 5 different treatments, with 3 replicate pens of 18 male or 18 female geese per pen for each treatment. This experiment included 2 stages, with geese at 1 to 28 d of age (the first stage) and 29 to 70 d of age (the second stage). The 5 different treatments were 1) system A (geese raised on a wire floor), 2) system B (geese raised on the floor), 3) system C (geese raised on the floor and transferred to to a wire floor), 4) system D (geese raised on a wire floor and transferred to the floor), and 5) system E (gees raised on the floor and transferred to a free range). Results showed that feed conversion rate, BW, and BW gain were significantly affected by rearing system and sex (P 0.05). Differences between sexes, but not rearing systems, were observed for only breast yield, thigh yield, and liver yield (P 0.05) by the rearing system, and only water, protein, and pH of the meat were affected by sex (P
