PANIC has been defined as ‘frantic and sudden fright’ (MacDonald 1972) and in animals is generally characterised by some form of disorientated, excessive escape behaviour, which is often inappropriate to the situation in which it occurs (Mills and Faure 1990).

Renal haemodynamics in the laying hen

Comparative Biochemistry and Physiology Part A: Physiology, 1981
Abstract 1. 1. The glomerular filtration rate (GFR) in colostomised laying hens decreased significantly during active shell formation. This reduction may play a role in the renal conservation of calcium during this period. 2. 2. Renal plasma flow (RPF) increased significantly during shell dormation.

Calcium metabolism and the laying hen

Journal of the Science of Food and Agriculture, 1963
AbstractThe rate at which calcium is removed from the blood during egg shell formation (100–150 mg./h.) is greater than the mean rate of calcium absorption from the food, and the balance is made good by mobilisation of skeletal reserves. The phosphorus liberated simultaneously is largely excreted in the urine.Occasionally the skeletons of laying birds ...
