Semen characteristics of the muscovy drake ( Cairina moschata ) as affected by seasonal variation
Seasonal variations of semen characteristics of the Muscovy drake were examined between January and July, 1981. Interrelationships among semen characteristics and libido as affected by seasonal changes in temperature, humidity and daylight hours revealed the following : conditioning the Muscovy drake to give semen increased its libido and improved semen quality ; in addition, peaks of sperm pro...
متن کاملOccurrence of reovirus infection in Muscovy ducks (Cairina moschata) in south western Poland.
During the summer 2012 an incidence of high mortality, above 44 percent, in two flocks of Muscovy ducklings in Poland was noted. The clinical signs included considerable weight loss and inability to walk. During the post-mortem evaluations dehydration and enteritis, gouty kidneys as well as hemorrhagic liver and spleen lesions were found. The laboratory diagnosis included agar gel precipitation...
متن کاملDescription of the Muscovy duck (Cairina moschata) karyotype.
The karyotype of the Muscovy duck originating from Cairina moschata was characterised on the basis of R and C bands. Chromosomal preparations obtained from an in vitro blood lymphocyte culture were RBG- and CBG-stained. The structures of nine and fourteen pairs of chromosomes were examined based on R bands and C bands, respectively. Ideograms of banded patterns of the analysed chromosomes were ...
متن کاملOverfeeding and genetics affect the composition of intestinal microbiota in Anas platyrhynchos (Pekin) and Cairina moschata (Muscovy) ducks.
To investigate the effect of overfeeding on the ileal and cecal microbiota of two genotypes of ducks (Pekin and Muscovy), high-throughput 16S rRNA gene-based pyrosequencing was used. The ducks were overfed for 12 days with 58% maize flour and 42% maize grain. Samples were collected before the overfeeding period (at 12 weeks), at 13 weeks, at 14 weeks, and 3 h after feeding. In parallel, ducks f...
متن کاملMolecular characterization and tissue-specific expression of invariant chain in the muscovy duck (Cairina moschata).
The invariant chain (Ii) plays an important role as a chaperone for MHC II maturation and facilitates antigen presentation in vertebrates. We cloned, characterized and made a homology analysis of healthy adult muscovy duck Ii (MDIi), from a poultry farm in the suburban district of Hefei city in China, by rapid amplification of cDNA ends (RACE)-PCR and by measuring expression of the MDIi ge...
