Cold Drinking Water Boosts the Cellular and Humoral Immunity in Heat-Exposed Laying Hens by Hatem M. Eltahan, Chang W. Kang, Vishwajit S. Chowdhury, Hossam M. Eltahan, Mostafa A. Abdel-Maksoud, Ayman Mubarak, Chun Ik Lim

“…This study aimed to investigate the effects of cold drinking water on cellular and humoral immunity in heat-exposed laying hens. One hundred and eight laying hens at 19 weeks old were placed into three treatments with six replicates of six hens in each group as follows: (1) hens were provided with normal drinking water (NW) under the control of thermoneutral temperature (CT: 25 ± 1 °C; CT + NW), (2) hens were provided with NW under high ambient temperature (HT: 35 ± 1 °C; HT + NW) for 8 h/d for a month, and (3) hens were treated under HT with cold drinking water (CW: 15 ± 1 °C; HT + CW) for 8 h/d for a 4-weeks. …”

Effects of Dietary Supplementation of Pomegranate Peel with Xylanase on Egg Quality and Antioxidant Parameters in Laying Hens by Styliani Lioliopoulou, Georgios A. Papadopoulos, Ilias Giannenas, Konstantina Vasilopoulou, Clare Squires, Paschalis Fortomaris, Fani Th. Mantzouridou

“…In this study, two levels of pomegranate peel byproduct (PPB) with or without the inclusion of xylanase enzyme were used to supplement laying hens’ diet, in a 2 × 2 full factorial design. A total of 48 Isa brown laying hens were fed the following experimental diets for 8 weeks: T1 (2.5% PPB); T2 (2.5% PPB and xylanase); T3 (5% PPB); T4 (5% PPB and xylanase). …”
