Productive performance of commercial VST12 eggs-type ducks rearing in farming conditions
The present study aimed to investigate the productive performance of VST12 eggs-type commercial ducks rearing in two farming models in Tan Long commune, Mang Thit district, Vinh Long province from 2020 to 2021. In each model, 1750 one-day-old ducklings (then selecting 1500 ducks for laying) for each model were arranged in an open sided house with backyard and swimming pond, appling rearing method of VIGOVA. The results show that survival rate from 0 to 8 weeks of age in model 1 and 2 were 96.91 and 97.71%; from 9 to 16 weeks of age were 98.58 and 99.03% respectively. Body weight at 16 weeks of age in model 1 and model 2 were 1308.6 g và 1322.2 g respectively. Laying rate, egg production, feed conversion ratio for 10 eggs and egg weight were 77.39%, 281.69 eggs/hen/52 weeks of laying, 1.95 and 71.40 g in model 1; 77.39%, 283.89 eggs, 1.93 and 70.09 g in model 2 respectively. Results confirmed that VST12 eggs-type commercial ducks rearing under farming conditions adapt well and have high productivity.
