The Production Capability of Grandparent Flock of CV Super M Duck Raised without Pond at Ha Noi University of Agriculture

Abstract

      An exotic grandparent flock of CV super M ducks conisisting of 4 lines A, B, C and D was completely raised without pond at Ha Noi University of Agriculture to assess the productive performance of gilt and laying stage. The results showed that, in gilt period (up to 24 weeks), the survival rate was very high, reaching 95 - 97%. At maturation age, the physical appearance of ducks was characteristic of high-yield of super meat duck. The body weight of two male lines A and C was 4.3 kg and 3.8 kg, respectively; while the other two female lines B and C was 3.6 and 2.8 kg, respectively, equivalent to the supplier firm’s specification. The average feeding cost for a grandparent gilt duck was VND 248,802.5. About 5% of CV super M ducks lays egg at 175 - 177 days of age, and reached the peak at 223 -

224 days old. Within 24 laying weeks, an average birth rate and egg production of B line was 69.12% and 116.1 egg/duck, respectively. The similar figure for D line was 75.70% and 127.2 egg/duck. The feed used for producing 10 eggs of B line was 4.4 kg, and for 10 hatching eggs was 5.0 kg. The figure for D line was 4.1 kg and 4.8 kg. The cost to produce 10 hatching eggs of both these lines was VND40,400 and VND 38.267, respectively. Both lines had good quality hatching eggs, the percentage of type I / total hatching eggs was 71% and 73% with line B and line D, respectively.
