The Effect of Raising Manner on The Moscovy Duck's Breeding Performance

By observing the raising manner how influence the moscovy ducks' breeding performance,we can discover the average laying rate from the ducks which are raised on the mash(37.25%)is higher than the data which comes from the ducks raised on the ground(33.15%)(P<0.05).There are no significant difference in the egg eligibility and livability,which is 95.43%,95.34%,100%,99.96% respectively.The ground raising's fertility(96.28%)is significantly higher than the mesh raising's(83.56%)(P<0.01).The results showed that Muscovy duck raised on mash had higher feeding benefits.
