The ontogeny of the tonic immobility (TI) response in domestic fowl chicks was studied during the first week of life. The TI response of naive White-Leghorn Gallus domesticus male chicks ( N =5–9), was tested at the age of 1, 2, 3, 5 and 7 days. TI

A study was conducted to examine the effect of contact lenses on egg production, egg weight, fear response, and mortality in White Leghorn hens. Two hundred laying hens in their second laying period (76 to 104 wk of age) were housed in 48.5 × 45.5 c

Estradiol benzoate (E 2 ) increases plasma lipids in hypothalamic obese, functionally castrated (OFC), obese laying (OL), and control laying hens (CONT). However, E 2 reduces fattiness in OFC but not in OL or CONT hens. Antiestrogen, such as tamoxife
