Physiological Stress in Laying Hens

Poultry Science, 2006
Stress responses in laying hens were mediated by continuous infusion of adrenocorticotropin (ACTH) via osmotic pumps. The ACTH was dissolved in saline solution (0.85%), and each pump delivered 8 IU of ACTH per kilogram of BW per day at the rate of 1 microL/h for 7 d. Control hens received pumps loaded with saline. Measurements were made at 6 d postpump

U.S. Consumer Preferences for Cage‐Free Eggs and Hen Housing Policies

Agribusiness, EarlyView.
ABSTRACT Farm animal welfare (FAW) continues to be a divisive issue in the egg industry. In the United States, 10 states and most major retailers have implemented policies or voluntary pledges to transition to 100% cage‐free egg sales. We use best‐worst scaling and discrete choice experiments to evaluate U.S.

A Study of Aflatoxicosis in Laying Hens

Poultry Science, 1970
Abstract INTRODUCTION THE lethal potential of aflatoxins was recognized when aflatoxins were discovered and found to be the etiological agent responsible for the losses of turkey poults (Blount, 1961), ducklings and chickens (Asplin and Carnaghan, 1961), swine (Loosmore and Harding, 1961), and calves (Loosmore and Markson, 1961) in Great Britain ...
