Brahma Rasayana enhances in vivo antioxidant status in cold-stressed chickens (Gallus gallus domesticus)

Sex differences in yolk hormones depend on maternal social status in Leghorn chickens (Gallus gallus domesticus).

Maternal hormones are known to be present in avian eggs and can have beneficial effects on chick development. Recently, differences in avian yolk steroid concentrations between the sexes have been demonstrated, and in this context steroids have been proposed to be part of the avian sex-determining mechanism. In our study, we show that it is very unlikely that androgen concentrations alone are t...

Evaluation of Intravenous Lidocaine Overdose in Chickens (Gallus domesticus)

Objective- To evaluate the total toxic dose of lidocaine and serum lidocaine concentrations resulting in clinical signs of toxicity in chickens. Design- Experimental study Animals- Eight healthy, female, 55-week-old chickens (Lohman breed) weighing 1.45 ± 0.17 kg (mean ± SD) Procedure- A loading dose of 2% lidocaine (4 mg/kg) was administered IV, followed by a constant-rate infusion at a dose o...

ANG II and baroreflex control of heart rate in embryonic chickens (Gallus gallus domesticus).

ANG II alters the short-term blood pressure buffering capacity of the baroreflex in many adult animals. In embryonic chickens, high plasma ANG II levels contribute to baseline mean arterial pressure (MAP, kPa) without changing heart rate (ƒH, beats/min). We hypothesized, on the basis of these features, that an ANG II-induced reduction in baroreflex sensitivity is present in embryonic chickens a...

Final Thesis Feto-Maternal Communication in Broiler Chickens (Gallus gallus domesticus)

CORAL SNAKE ANTIVENOM PRODUCED IN CHICKENS (Gallus domesticus)

The production of anti-snake venom from large mammal's blood has been found to be low-yielding and arduous, consequently, antivenom immunoglobulins for treatment are achieved regularly as polyvalent serum. We have standardized an undemanding technique for making purified immunoglobulin IgY antivenom consisting of polyclonal antibodies against coral snake venom in the egg yolk of immunized hens....
