Abstract:
Blood samples collected on 206 rabbits from breeding experiment conducted at rabbit unit of Teaching and Research, Federal University of Technology, Akure were analysed to study the effects of genotype, sex and age on some haematological values namely Packed Cell Volume (PCV), hemoglobin concentration (HBC), Red Blood Cells (RBC), White Blood Cells (WBC), Mean Corpuscular Haemolobin (MCH), Mean Corpuscular Haemolobin Concentration (MCHC), Mean Corpuscular Volume (MCV) and Erythrocyte Sedimentation Rate (ESR). The 206 rabbits, 59 males and 147 females used in the study comprised 7 genetic groups viz 54 New Zealand whitexNew Zealand white (NZWxNZW), 65 ChinchillaxChinchilla (CHAxCHA), 17 ChinchillaxNew Zealand white Dutch belted (CHAxNZWDBD), 28 New Zealand white Dutch beltedxNew Zealand white Dutch belted (NZWDBDxNZWDBD), 14 New Zealand whitexNew Zealand white Dutch belted (NZWxNZWDBD),7 New Zealand white CroelxNew Zealand white Croel (NZWCRLxNZWCRL) and 11 New Zealand whitexChinchilla (NZWxCHA), were aged 3-4, 5-6, 7-8, 9-10 and 11-12 months and above. The least squares model included main effects of genotype, sex and age as factors among others that contribute to variations in haematological values in rabbits. There was genotype differences (p<0.05) in PCV, WBC, MCH and ESR. Genotype NZWxCHA recorded highest mean values in PCV, HBC and RBC. The haematological variables by sex were not different (p>0 .05) except in ESR where females recorded higher significant (p<0.05) mean value than the males. Age effect were obtained (p<0.001) for WBC and ESR and for ((p<0.05) HBC, MCH and MCHC. The haematological values reported in this study could be useful for reference in health management of rabbits of different genotypes, sexes and ages in the humid tropics.
