ABSTRACT: In a previous study, we demonstrated that a 15% feed restriction (FR) during the first 2 wk after hatch could improve gait in Pekin meat ducks, but did result in reduced breast mass. We hypothesized that feed restriction after day 5 followi

Publikováno v: Journal of Applied Poultry Research, Vol 28, Iss 4, Pp 858-866 (2019)

SUMMARY: Like other poultry species, Pekin ducks may develop gait abnormalities due to increased muscle growth relative to the skeletal system. Previous studies have shown that Pekin leg bones grow exponentially in terms of mineral deposition during

ABSTRACT: By some accounts, ducks were domesticated between 400 and 10,000 yr ago and have been a growing portion of the poultry industry for decades. Ducks specifically, and waterfowl in general, have unique health, housing, nutrition and welfare co

Publikováno v: Catalysis Communications, Vol 152, Iss , Pp 106284- (2021)

Iron-based catalysts are the most suitable candidates for converting CO2 or CO2-rich syngas to hydrocarbons. However, several issues about the mechanism of CO2 hydrogenation are still unclear. In this work, we investigated the performance of an iron-
