tlooto Summary
This study investigates the effects of alternating low and high calcium diets on laying hen performance, egg quality, and serum indexes at the late stage of laying.
Abstract
: The purpose of this experiment was to study the effects of alternation feeding of high 262 and low calcium diets on performance, egg quality and serum indexes of laying hens at late period 263 of laying. Sixty-weight 68-week-old Dawufen No.1 hen breeders were selected and randomly 264 divided into 2 groups with 32 birds in each group, and single cage reared in individual intelligent 265 cage. The laying hens in control group were fed 43.3 and 86.7 g middle calcium diet (calcium 266 content was 3.66%) at 08:00 and 14:00, respectively. The laying hens in experimental group were
