H/L, Laying Hen, malondialdehyde, THI, uric acid
This study is conducted to investigate the effect of THI on the concentration ofMDA, uric acid blood plasma and lymphocytes: heterophil ratio of laying hen. One hundred laying hens arerandomly divided into two treatments, each treatment consist 50 birds. Treatments in this work are two levels of temperature humidity index rim = 89 and 72), which calculated based on dry and wet bulb thermometer in laying housing, located in Kuningan and Bandung. The experiment period lasted 8 weeks, blood samples were collected weekly Malondialdehyde, uric acid and lymphocytes: heterophilratio is recorded by spectrophotometer following Biolabo Kit. Data are analysed using paired t-test method. Based on results of this study, the level ofMDA and uric acid significantly increase (P < 0.01) in the high THI (89). On the other hand, lymphocytes/ hetemphils (H/L) ratio decreases (P < 0.05). These data suggest that high THI (89) enntrihutes of laying stress is caused by the level of temperature and humidity in environment and inside the housing.
