Effect of supplementation on the growth and laying performance of confined and scavenging local chickens

Thuy NT, Ogle B


A total of 225 crossbred male and female local chickens (Noi x Tau Vang) at 4 weeks of age were allocated at random to 3 treatments, and with 3 households as replications. The treatments were Control: (CPFD), total confinement, with paddy rice (P), fishmeal (F) and duckweed (D) provided ad-libitum in 3 separate feeders; SPFD: scavenging, with P, F and D provided ad-libitum and SPD: scavenging, with P and D provided ad libitum. The birds were weighed each week between 4 and 20 weeks of age and feed consumption was recorded each day throughout the growing period. Egg production and egg quality were recorded from 21 to 30 weeks of age. Total feed dry matter (DM) and crude protein (CP) intake and average daily weight gain were significantly different among treatments (P<0.05). DM and CP intakes in CPFD (63.2 and 10.8 g/day, respectively) were higher than in SPFD (54.6 and 8.93 g/day, respectively) and SPD (47.7 and 5.01g/day, respectively). However, there were no significant differences in feed conversion ratio among treatments. Liver and gizzard weights and abdominal fat in CPFD were higher than on the other two treatments, although there were no differences in carcass yield. Hen-day production in CPFD was higher (25.4 %) than that in SPFD (21.9 %) and SPD (17.7 %) (P<0.001). However, there were no significant differences in feed consumed per egg, egg weight and egg yolk color among treatments
