Variations in some haemato-biochemical markers from a small flock of free ranging Nguni, Boer and Non-descript goats during late gestation and early lactation periods

This study aimed to assess the influence of genotype and physiological status on blood metabolites of Nguni (10), Boer (10) and Non-descript (10) goats during late gestation and early lactation periods. Blood samples were collected and analysed using standard methods. The result revealed that, Nguni goat had higher (P < 0.05) mean values of red cell counts (13.37 x10¹¹/L), haemoglobin (9.07 g/dL) and creatine kinase (269.54 U/L) compared to Boer (9.96 x 10¹¹/L, 7.94 g/dL and 132.16U/L) and Non-descript (12.98 x10¹¹/L, 7.85 g/dLand 143.50 U/L) goats, respectively. TheNgunigoat alsohad higher mean values of glucose (3.38 mmol/L) and urea content (5.51 mmol/L) compared to Boer goats (2.96 mmol/L and 4.45 mmol/L) and Non-descript (2.50 mmol/L and 3.90 mmol/L). There was higher mean values of red cell counts (14.44 x 10¹¹/L), haemoglobin (8.57 g/dL), glucose (3.12 mmol/L), sodium (141.74 mmol/L) and calcium content (2.37 mmol/L) during late gestation compared to early lactation (9.77x 10¹¹/L, 8.00 g/dL, 2.77 mmol/L, 137.37 mmol/L and 2.23 mmol/L) period. It was concluded that, genotypes and physiological status had influence on blood metabolites of goats.
