dc.description.abstractThis study was conducted to determine the body condition, metabolic and haematologic profiles reflecting the metabolic energy status prior to artificial insemination, during the different trimesters of pregnancy and at postpartum period (PP), in Friesian x Bunaji (FR x BJ) and Bunaji (BJ) cows, placed on the same feeding regimen. Twenty eight cows comprising of 11 FR x BJ and 17 BJ were observed for normal cyclicity. Only 8 cows (4 FR x BJ and 4 BJ) that showed normal cyclicity were used for the study. They where synchronized using a single intramuscular injection of 25 mg of PGF2α and inseminated using Friesian semen. Body condition score (BCS) was obtained every morning before feeding during pre–insemination, pregnancy and PP at 30 days interval. Blood samples were similarly obtained, processed for serum and assayed for metabolites, electrolytes and calcium. Also, blood samples in sodium salt of ethylenediaminetetraacetate containing bottles were used for the determination of haematological parameters. The body condition score of the BJ cows was significantly (P < 0.05) higher than that of the FR x BJ cows in the second trimester of pregnancy (3.79 ± 0.10 vs 3.29 ± 0.07). The pre–insemination (control) values (range) for metabolic parameters for both breeds were glucose (GL) (2.17 ± 0.44 – 2.29 ± 0.32 mMol/L), tryglycerides (TRG) (0.61 ± 0.07 – 0.74 ± 0.08 mMol/L), cholesterol (CHL) (4.85 ± 0.77 – 5.15 ± 0.58 mMol/L), urea (UR) (7.41 ± 0.97 – 10.46 ± 2.68 mMol/L), creatinine (CRT) (188.68 ± 15.32 – 135.13 ± 23.05 mMol/L), sodium (Na+) (152.38 ± 7.43 – 152.75 ± 5.53 mMol/L), potassium (K+) (4.30 ± 0.29 – 4.31 ± 0.29 mMol/L) chloride (Cl–) (103.38 ± 5.16 – 106.25 ± 3.69 mMol/L), bicarbonate (HCO3 2–) (17.23 ± 2.72 – 23.00 ± 2.49 mMol/L), total protein (TP) (55.19 ± 5.16 – 59.54 ± 6.05 g/l) and albumin (ALB) (27.69 ± 3.10 – 29.02 ± 5.27 g/l). There was increase in GL, TRG, CHL, HCO3 2–, Ca2+, TP, and ALB levels in the two breeds, with onset of pregnancy, 7 but CRT, UR, Na+, K+, and Cl– levels decreased with onset of pregnancy. There were no significant differences (P > 0.05) in the levels of GL, UR, CHL, Na+, K+, HCO3 2–, Ca2+, TP and ALB of the two breeds, throughout the reproductive stages. However, significant differences were obtained in other metabolic parameters at different reproductive stages. The control values for haematologic profiles for both breeds were Packed cell Volume (PCV) (37.38 ± 3.24 - 27.20 ± 5.34), Haemoglobin Concentration (Hb. Conc.) (13.10 ± 0.90 - 27.23 ± 5.27) and White blood cell count (WBC) (11.19 ± 2.01 - 14.67 ± 2.24). There was an increase in white blood cell count with onset of pregnancy in the FR x BJ, but a continuous drop throughout pregnancy, in the Bunaji cows. The present research has provided a baseline data on especially metabolic parameters of FR x BJ and BJ cows prior to insemination, during the different trimesters of pregnancy and at postpartum period, valuable in future clinical and experimental applications.en_US
