Histology of the Ovary of the Laying Hen (Gallus domesticus)
The laying hen (Gallus domesticus) is a robust animal model for epithelial ovarian cancer. The use of animal models is critical in identifying early disease markers and developing and testing chemotherapies. We describe the microscopic characteristics of the normally functioning laying hen ovary and proximal oviduct to establish baselines from which lesions associated with ovarian cancer can be...
متن کاملThe vocal expression of feeding motivation and frustration in the domestic laying hen, Gallus gallus domesticus.
Thwarting of feeding behaviour in the laying hen results in an increase in stereotyped pacing, displacement preening, and the gakel-call. These behaviours therefore reflect the frustration arousal caused by the thwarting of feeding behaviour. This raises the question whether the level of frustration also varies with the intensity of the motivation to perform the thwarted behaviour. This study i...
متن کاملExpression and localization of growth hormone receptor in the oviduct of the laying hen (Gallus domesticus).
The purpose of the present study was to examine growth hormone receptor (GHR) gene expression by real-time PCR and demonstrate immunocytochemically the localization of GHR in four chicken oviductal parts, i.e. infundibulum, magnum, isthmus and shell gland. Experiments were carried out on Hy-Line laying hens decapitated 2 h after oviposition. GHR mRNA was expressed in all examined oviductal segm...
متن کاملEffects of fasting on serum lipids and lipoprotein profiles in the egg-laying hen (Gallus domesticus).
The effects of a 24-h fast on serum lipids and lipoprotein profiles in commercial laying hens were investigated. Blood was analyzed at 34 and 46 weeks of age from Single Comb White Leghorn hens that had been either fed ad libitum or had been fasted for 24 h prior to collection. At 12 weeks, birds were divided into 16 biological isolation units, with 8 replicate units assigned to each treatment ...

Hen’s native chicken reproductive organ health status evaluation is important for raising Indonesian native chicken in order to support protein supply for people demand. This study aimed to discover the images of Indonesian hen’s native chicken reproductive organ using ultrasonography. There were 18 hens that used in this study and divided into two groups, 15 hens for brightnessmode ultrasonogr...
