Journal Title: Acta Scientiarum Polonorum Zootechnica - Year 2015, Vol 14, Issue 3
Abstract
The aim of the study was to compare growth rate and body weight of Pekin and Muscovy ducks and their hybrids (mulards). It was established that up to week 6 of life inclusive, Pekin ducks weighed more compared to Muscovy ducks and mulards, differences were confirmed statistically. From week 1 to 7 of life, mulards had significantly lowest body weight compared to ducks from other two groups. Pekin ducks showed significantly highest body weight gain between weeks 3 and 4 of life, and for Muscovy ducks of both sexes it was between weeks 4 and 5 of breeding. On the other hand, for mulards the highest gains of body weight was observed between weeks 5 and 6 of life. In all groups of ducks the highest growth rate was noted between weeks 1 and 2 (from 100 to 119%). After week 3 of life, intensity of Pekin ducks’ growth decreased from 38 to 9% between weeks 7 and 8, for Muscovy drakes from 43 to 2% between weeks 11 and 12, for Muscovy ducks from 46 to 3% between weeks 9 and 10 and for mulard ducks from 46 to 5% between weeks 9 and 10 of life.
