Determination the rate of crude protein and energy metabolism suitable for crossbred meat Ducks which were reared on terrestrial ground in Tieu Can district, Tra Vinh province
Assessment for growth performance and supply mixture concentrate feed of meat duck from August to October 2021 at household farm on Tieu Can district, Tra Vinh province. Collected numerical data was on 150 crossbred meat ducks from 1 day - age which was devided into 3 treatments (NT1, NT2, NT3) by completely random menthod and repeating 5 times for every treatment (10 ducks/time/experimental unit). Feeding process was designed with 2 phases follow rates of crude protein (CP) and metabolism energy (ME) of experimental diets that was compatible with each period of ages. Last of staring phase, growth ability of young ducks was effected not significantly by types of experimental diets but difference were significant statistically in consumption feed and ME intake content of meat ducks between 3 treatments. However experimental conditions have been affected significantly to the levels of CPI, MEI and consumption of nutrients content of ducks during growing phase (P < 0.05). When ending experimental process body weight and increasing average body weight gain of ducks with 3 treatment those were the best effect (sequence of 1,436g và 197.4 g/duck/day) and feed conversion ratio was also better without this treatment than the others (2.07 kg/kg increasing average body weight gain). Generally efficiency of adaptation and development with meat ducks were more clearly defined when rearing on terrestrial ground with characteristics of diet through the condition of this experiment.
