Effects of Some Factors on Some Blood Constituents of Saanen and Nilotic Goats (Capra hircus) in Sudan

Abstract

The present study was conducted to determine the effect of the breed, sex, season and the physiological status on some haematological and serum biochemical parameters of Saanen goats, under Sudan conditions . The effect of the breed was done by comparing the studied parameters in the Saanen goats with Nilotic ones of the same age. The Nilotic goats showed significantly higher values for Hb, PCV, MCV, MCH, MCHC, ALP and K. The reverse was true for neutrophils T.P, uric acid, AST, cholesterol, Na, Ca, P. RBC, TWBC, lympohcytes, monocytes, eosinophils basophils, glucose, albumin, globulin, creatinine , urea , triglycerides , ALT and Mg were not influenced by the breed . The investigated parameters were measured in Saanen goats during winter and the wet summer of the year 2008.RBC, TWBC, T.P, albumin, creatinine, AST, ALP, Na, Mg, Ca, were significantly higher during winter than wet summer. Conversely, MCV, MCH, MCHC, monocytes, eosinophils, glucose, urea, uric acid, ALT, K and P were low in winter animals compared with wet summer animals . Hb, PCV, neutrophils, lymphocytes, globulin, cholesterol and triglycerides did not vary with the season. Female goats had significantly higher Hb, PCV, RBC, MCH, TWBC, eosinophils, cholesterol, urea, uric acid, ALT, and Na than male goats .In contrast male animals had significantly higher , neutrophils, creatinine, AST and ALP than females. No intersex variations were observed in MCV,MCH, lymphocytes, monocytes, glucose , T.P , albumin , globulin , triglycerides ,K , Mg ,Ca or P. For the physiological state study three groups of animals were used, pregnant-lactating, non pregnant-lactating and non pregnant-dry. The physiological state did not affect neutrophils , lymphocytes , monocytes , cholesterol or triglycerides. The non pregnant dry animals had the highest , Hb , PCV, MCV, Mg and P. The pregnant –lactating animals had the highest ,RBC , TWBC, T.P, albumin, globulin , creatinine , AST, ALP and Ca. the non pregnant-lactating ones exhibited high MCH, MCHC, eosinophils, glucose, urea ,uric acid, ALT, K and P. The results were compared and discussed with other researchers findings. xi It is recommended that further studies to be done and to correlate the studied parameters with the animals metabolic and nutritional status.
