Effect On Growth

ABSTRACT Pekin ducks grow faster and show a faster and higher thyroidal 131I uptake than Muscovy ducks. Treatment with a total of 15 mg stilboestrol during the first 4 weeks had no effect on growth, thyroid weight or thyroidal 131I uptake in male or female Pekin ducklings. In male Muscovy ducklings the same treatment caused a marked inhibition of growth, a decrease in thyroid weight and a lowered thyroidal 131I uptake. Thyroxine, administered simultaneously in physiological doses, did not prevent inhibition of growth. It is therefore concluded that this inhibition is not due to the lowered thyroid function.

Pathogenic prion protein (PrPSc), converted from normal prion protein (PrPC), causes prion disease. Although prion disease has been reported in several mammalian species, chickens are known to show strong resistance to prion diseases. In addition to chickens, the domestic duck occupies a large proportion in the poultry industry and may be regarded as a potential resistant host against prion disease. However, the DNA sequence of the prion protein gene (PRNP) has not been reported in domestic ducks. Here, we performed amplicon sequencing targeting the duck PRNP gene with the genomic DNA of Pekin ducks. In addition, we aligned the PrP sequence of the Pekin duck with that of various species using ClustalW2 and carried out phylogenetic analysis using Molecular Evolutionary Genetics Analysis X (MEGA X). We also constructed the structural modeling of the tertiary and secondary structures in avian PrP using SWISS-MODEL. Last, we investigated the aggregation propensity on Pekin duck PrP using AMYCO. We first reported the DNA sequence of the PRNP gene in Pekin ducks and found that the PrP sequence of Pekin ducks is more similar to that of geese than to that of chickens and mallards (wild ducks). Interestingly, Pekin duck PrP showed a high proportion of β-sheets compared to that of chicken PrP, and a high aggregation propensity compared to that of avian PrPs. However, Pekin duck PrP with substitutions of chicken-specific amino acids showed reduced aggregation propensities. To the best of our knowledge, this is the first report on the genetic characteristics of the PRNP sequence in Pekin ducks.
