Seminal Plasma Protein as a Biomarker for Fertility and Hatchability in the Domestic Fowl Gallus Domesticus
نویسنده
چکیده
This study was aimed at investigating the use of seminal plasma protein concentration to predict fertility and hatchability in the domestic fowl. Forty cocks with acceptable sperm motility and morphology were used and the seminal plasma protein concentration determined by the Biuret method. The result revealed a negative significant correlation between the seminal plasma protein concentration with sperm motility (r = -0.5920, p<0.05), Y = -0.3144X+2.1578X+74.324, R = 0.3506 (p<0.05). A significant positive correlation with percentage dead spermatozoa r = 0.9743 (p<0.01), R = 0.9493, p<0.01), percent abnormal spermatozoa, r = 0.8425, p<0.01), R = 0.7098 (p<0.01), Y = 0.357X+1.5364X+9.1886. Egg fertility and Hatchability were negative but significantly correlated with seminal plasma protein concentration r = -0.6302 (p<0.01) vs r = -0.8438 (p<0.01) and Y = 0.8977X-5.8289X+81.628 vs Y = -0.2391X+3.3871X+60.771, respectively. There was low correlation with the quantitative semen characteristics. Prediction of Ymax from Seminal plasma protein concentration (X) showed that the best semen quality, highest percent fertility and hatchability would be obtained when the concentration of seminal plasma protein is >3.00 g/100 mL but <6.00 g/100 mL. It was concluded that seminal plasma protein concentration could be used as a biomarker for prediction of fertility and hatchability in the domestic fowl.

Background: Foreign body in esophagus in birds is rarely reported in literature. Most common site of foreign body in birds is proventriculus and ventriculus. The purpose of this study is to discuss the diagnosis of a large sharp foreign body in the distal third of the neck by plain radiography and its retrieval through esophagotomy and subsequent survival of the fowl.

When domestic fowl were maintained under constant incandescent illumination from time of hatching, the rate of egg production was similar to that of control birds on a diurnal schedule. Hatchability offertile eggs produced by such hens was found to be unaffected by lighting treatment of the parents. Fertility was, however, markedly impaired in the males reared under continuous light. Artificial...

An adult native cock (Gallus gallus domesticus) referred to the aviary clinic with multiple different sizes of round dermal nodules. The bird died few days later, and was then submitted for further evaluation. Macroscopic and microscopic examinations as well as a PCR test were done to identify type and cause of the tumor. In histopathological assessment of biopsy specimen, it consisted of inter...
