The transcriptome landscapes of ovary and three oviduct segments during chicken (Gallus gallus) egg formation.

The avian embryo develops within a specialized biological container (eggshell) that contains crucial nutritional compartments (albumen, yolk). We analyzed the transcriptome of ovary and three segments of oviduct, including magnum, isthmus and uterus in the chicken during egg formation. RNA-Seq libraries (42 in total) for ovary and three different parts of the oviduct were sequenced for two different phases of egg formation.

De novo transcriptome assembly and identification of genes associated with feed conversion ratio and breast muscle yield in domestic ducks.

Breast muscle yield and feed conversion efficiency are the major breeding aims in duck breeding. Understanding the role of specific transcripts in the muscle and small intestine might lead to the elucidation of interrelated biological processes. In this study, we obtained jejunum and breast muscle samples from two strains of Peking ducks that were sorted by feed conversion ratio (FCR) and breast muscle percentage into two-tailed populations.
