Haematology of the crosses of West African dwarf rams with Permer and their castrates.

The haematological status of five West African dwarf (WAD) x Permer (P) rams and five WAD x Permer castrated rams (PC) was determined at 9.00 a.m. and 6.00 p.m. every Monday for five weeks. The variables measured were: haemoglobin content (Hb), packed cell volume (PCV), mean corpuscular haemoglobin concentration (MCHC), platelet (P), white blood cell (WBC), neutrophil (N), lymphocyte (L), monocyte (M), and eosinophil (E) counts. With the exception of N, L, and E, the values were not constant. The values of WBC, N, and L depended on the type of ram used. The time of the blood collection affected the Hb, WBC, and E concentrations. The value of M varied most (depending on the time of blood collection, week of determination, type of ram).
