Haematological and Plasma Biochemical Parameters in Response to Natural Coccidian Infection in Barbari and Jamunapari Goat Breeds in Semi-arid Tropics

Abstract

Background: Small ruminants like goats are considered the most resourceful and efficient animal all over the world. Eimeria species causes disease in goats associated with poor growth, diarrhoea and decrease in production, high morbidity and mortalities. The present study was conducted to analyse the haematological and biochemical parameters in response to natural coccidian infection in Barbari and Jamunapari goat breeds in semi-arid tropics. Methods: A total of 474 goats were examined; 96 goats were selected (48 Barbari and 48 Jamunapari) and divided on the basis of high (12 males and 12 females) and low (12 males and 12 females) oocyst per gram (OPG) counts of both Barbari and Jamunapari goats. The blood was aseptically collected from the jugular vein, using a 22-gauge needle for each animal separately in 5 ml blood for the haematological and biochemical estimations. Result: In haematological parameters of Barbari goats there were no significant (P greater than 0.05) differences in males and females. Although significantly higher values of RBC were observed in low OPG females, similar results were also observed in Hct, Mcv, Hb, MCH and MCHC. Whereas, in WBC, Lymphocyte, Monocyte and Granulocyte statistically had no significant (P greater than 0.05) differences among all the groups. In haematological parameters of Jamunapari goats no significant (P greater than 0.05) differences was seen in males and females of both the groups. The same group of Barbari goats were also selected for biochemical parameters and high OPG females had significantly (P less than 0.05) higher blood glucose values. The blood potassium concentration was found to be significantly (P less than 0.05) higher in low OPG males compared to high OPG males. The same group of Jamunapari goats were selected for biochemical parameters and ALT, total protein and globulin had significantly (P less than 0.05) higher values in high OPG females than others. A/G ratio had significantly (P less than 0.05) higher value observed in high OPG males.
