Twenty four West African Dwarf (WAD) goats of both sexes (12 bucks and 12 does) raised under intensive system and weighing between 5 and 11 kg with different coat colours (Black, Brown, Tan and White) were used for this study to evaluate the effects of sex and coat colour on their haematological and physiological parameters in south-western Nigeria. Blood sampling was done weekly for 8 weeks. Parameters examined were Red Blood Cell count (RBC), White Blood Cell count (WBC), Haematocrit (HCT), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC), Mean Corpuscular Volume (MCV), Haemoglobin Concentration (Hb) Red Cell Distribution Width (RDW), Pulse Rate (PR), Respiratory Rate (RR), Rectal Temperature (RT) and Skin Temperature (ST). Results showed that coat colour had significant effects (p0.05) influence of sex on RR, RT and ST. Variation in coat colour had significant (p0.05) among goats of different coat colours. White coat coloured goats recorded the highest value of PR (97.2±0.10 bm-1) which was similar (p>0.05) to the observed value for goats with Black coat colour. Goats with Black coat colour had higher (p |
