Haematological, serum biochemical and hormonal profile in West African Dwarf goats during pregnancy

Abstract

Abstract The haematological attributes during pregnancy assumed new importance when it was realised that pregnancy is a form of physiological stress and hormones appear to be involved in the process of pregnancy and parturition. Hence, an experiment aimed at assessing and determining the haematological, biochemical and hormonal profile during pregnancy was conducted for five (5) months using twelve (12) artificially inseminated female West African Dwarf goats aged 2 – 4 years with live weights ranging from 15 to 26 kg. Does were raised semi‑intensively throughout the duration of the experiment. Blood was collected once a month for haematological, biochemical and hormonal analysis. Data obtained were analysed by the method of least squares analysis of variance (SAS, 2003) using a general linear model appropriate for a completely randomised design. The gestation period had a highly significant (p < 0.001) effect on red blood cell (RBC) and white blood cell (WBC) counts. Cholesterol and glucose were significantly (p < 0.001) affected by the gestation period, similar to the cortisol and progesterone profile (p < 0.001). It can be concluded from this study that RBC counts were highest in the 4th week, WBC counts in the 8th week, cholesterol in the 12th week, glucose in the 8th week, progesterone and cortisol concentrations in the 20th week of gestation, respectively, in the West African Dwarf goats which reflect the physiological demands of pregnancy, foetal growth, and development. These changes can be used as a tool for monitoring foetal health and proper handling of pregnant does.
