Title: Physiological Responses of Goats (Capra hircus) to Haemorrhage as Influenced by Splenectomy
Author: Abdalla, Selma E.; Abdelatif, Abdalla M.
Abstract: The objective of this study was to evaluate and compare the effects of 25% haemorrhage on physiological responses in spleen-intact and splenectomized adult goats. The magnitude of blood loss was expressed as percentage of initial blood volume after plasma volume determination by dye dilution. Haemorrhage resulted in significant increases in rectal temperature (Tr), respiration rate (RR) and heart rate (HR) values in normal and splenectomized animals. The values of packed cell volume (PCV), haemoglobin concentration (Hb) and total leukocyte count (TLC) were significantly lower in haemorrhaged normal and splenectomized animals. These parameters decreased immediately after haemorrhage in splenectomized animals and after 6 hrs in normal animals. In haemorrhaged animals, the lymphocytes, eosinophils and monocytes ratios showed lower values whereas neutrophils ratios were higher. The serum total protein and albumin concentrations decreased significantly in response to haemorrhage in normal and splenectomized animals. The plasma glucose level increased significantly in haemrrhaged animals. During recovery, haemorrhaged splenectomized animals maintained higher values of (Tr) and (HR) and lower values of (PCV) and (Hb) compared to haemorrhaged spleen-intact animals.
