Item Effects of dietary replacement of fish meal with crayfish waste meal on the blood profile of rabbits(Nigerian Journal of Animal Production 49(1) 304-312, 2022) Emerue, P.C.; Akinbola, E.T.; Omole, A.J.This study was conducted to evaluate the effect of the dietary replacement of fish meal (FM) with crayfish waste meal (CWM) on the blood profile of rabbits. A total of sixteen crossbred rabbits of about 10 weeks of age, with an average weight of 4.0±0.06kg were used for the experiment in a 90-day feeding trial. The diets used for the experiment contained graded levels of Crayfish waste meal (CWM)as replacement for fish meal (FM). The rabbits were assigned to four dietary treatments with four rabbits per treatment in a completely randomized design (CRD). Dietary treatments contained 0%, 50%, 75% and 100% crayfish waste meal for diets 1, 2, 3 and 4 respectively. Data collected were packed cell volume (PCV), Red blood cells (RBC), White blood cells (WBC), Mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC), serum metabolites, total protein, albumin, aspartate amino transferase (AST), alanine amino transferase (ALT) and others. Data were analyzed using analysis of variance and the means were separated using Duncan multiple range test. There were no significant differences (P<0.05) in all the parameters measured for haematology across dietary treatments except in the PCV, RBC and MCV. Rabbits in T2 had higher PCV (25.50%) and RBC (6.61x106 uL) than those in T1, (18.50% and 5.07x106 uL, respectively). The blood biochemical composition showed no significant differences (P<0.05) in Albumin, ALT and creatinine across the dietary treatments. However, total serum protein, globulin, albuminglobulin ratio, AST, urea, glucose and cholesterol of the rabbits were significantly (P<0.05) influenced by the treatments with T4 having significantly higher total protein (12.75g/dl) and globulin (10.10g/dl) than the other treatments. Therefore, the values of haematological and biochemical parameters obtained in this study which were in the normal range and the good health status of the rabbit across the treatments is an indication that cray fish waste meal is nutritionally adequate without any deleterious effect on the animals.Item HAEMATOLOGICAL PROFILE OF RAMS FED GRADED LEVELS OF CASSAVA PULP AND DRY POULTRY DROPPINGS BASED DIET(2022) Emerue, P.C.; Akinbola, E.T.The study was carried out to assess the haematological indices in rams fed cassava pulp and sun-dried poultry droppings as an alternative energy and protein source. A total of twelve West African Dwarf rams aged 9-12 months were used for the experiment of 70 days feeding trial. Chopped elephant grass (Pennisetum purpureum) was used as basal diet and four diets of Cassava pulp and Dry poultry droppings as concentrate supplements-based diets. The four diets (T1 - 0% Cassava pulp and 0% Dry poultry droppings, T2 - 25% Cassava pulp and 25% Dry poultry droppings, T3 - 50% Cassava pulp and 50% Dry poultry droppings, and T4 - 75% Cassava pulp and 75% Dry poultry droppings) were fed to the rams at the rate of 3% of the body weight. The rams were divided into four treatments in a completely randomized design. Data collected were haematological parameters such as packed cell volume, red blood cell, white blood cell, haemoglobin and many others. Data were analyzed using analysis of variance and the mean were separated using Duncan multiple range test. The haematological indices of the animals were within the normal range reported for sheep. The PCV, haemoglobin, RBC, WBC, platelet and lymphocyte were however significantly (P<0.05) higher in T1 rams than other treatment groups. These are indications of no deleterious effect of cassava pulp and dried poultry droppings on the blood profile and health of the animals.
