Effect of Corticosterone on Hypothalamic Corticotropin-releasing Hormone Expression in Broiler Chicks (Gallus gallus domesticus) Fed a High Energy Diet

Effect of L-Thyroxine on Some Blood Parameters in Broiler Chicks (Gallus gallus) of Different Ages

The effect of intraperitoneal administration of a single dose (1μg/g) of thyroxine (T4) after 24, 48 and 98 hours on plasma total proteins, albumin fraction, uric acid, glucose, triglycerides and cholesterol has been investigated in broiler (Hubbard) chicks of 15, 25 and 35 days of age. Thyroxine treatment resulted in a significant decrease of plasma proteins after 96 hours of the experiment in...

Effect of Feed Withdrawal and Heat Acclimatization on Stress Responses of Male Broiler and Layer-type Chickens (Gallus gallus domesticus)

This experiment was conducted to evaluate the effect of feed withdrawal (F) and heat acclimatization (A) on malebroiler and -layer chickens responses to acute heat stress (AHS) at four weeks of age. Totals of ninety male chicks of broiler or layer type were randomly allocated into 30 pens of grower batteries with raised wire floors. Chicks were subjected to F and A three times a week through th...

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

Optics of cone photoreceptors in the chicken (Gallus gallus domesticus)

Vision is the primary sensory modality of birds, and its importance is evident in the sophistication of their visual systems. Coloured oil droplets in the cone photoreceptors represent an adaptation in the avian retina, acting as long-pass colour filters. However, we currently lack understanding of how the optical properties and morphology of component structures (e.g. oil droplet, mitochondria...
