Abstract

Physiological effects of Roselle calyces extract in some blood parameters in laying hensR. J. T. Al-Baghdadi Coll. of Vet. Med./ Univ of Al-QadisiyaAbstractThis study was designed to investigate the physiological effects of alcoholic extract of Calyces of Roselle (Hibiscus sabdariffa) in some blood parameters in laying hens. 30 layers, 49 week old belonging to the Isa Brown breed were randomly divided into two groups of 15 layers each, both are received basal diet. Group 1 served as control which was orally administered 2ml/kg body weight of distilled water. Group 2 served as treated group which was orally administered alcohol extract of Hibiscus sabdariffa calyces at a dose of 200mg/kg BW dissolved in 2 ml of distilled water. The groups received the water and extract daily to individual layers at 6:00 o’clock in morning, after that drinking water and feed were provided ad libitum, the experiment lasted 8 weeks from 25/12/2009 until 25/2/2010. The effect of the extract was assessed by estimating red blood cells count, Hb concentration, white blood cell count, and serum: total protein, cholesterol, LDL and HDL, The results revealed that Roselle calyces extract produced significant increase in the levels of Hb conc., white blood cells and HDL, and significant decrease in the level of LDL, while the numbers of red blood cells and levels of total serum protein & cholesterol had non significant elevation in Group 2 compared to Group 1.
