TY - JOUR AU - Swanson, Milo H. AU - Johnston, Gary W. TI - Restricted feeding of Leghorn layers JF - California Agriculture JO - Calif Agr Y1 - 1975/11/01 VL - 29 IS - 11 SP - 10 EP - 11 PB - University of California Agriculture and Nature Resources SN - 0008-0845 UR - http://www.ucanr.edu/sites/calagjournal/archive/?article=ca.v029n11p10 AB - A number of variables govern the amount of feed consumed daily by full-fed laying hens. Most important are body weight, ambient temperature, energy level of the feed, and egg production rate. A change in any one of these variables causes a compensatory change in feed intake as the birds attempt to adjust energy consumption to energy needs. But chickens are not all equally proficient in making that adjustment.
