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.Item EFFECTS OF WALLOWING, SEX AND DAYTIME ON THE THERMOREGULATORY RESPONSE OF GEESE AT HIGH TEMPERATURE HUMIDITY INDEX(Proceedings of 26th Annual Conference of ASAN-NIAS, 2021) Ewuola, E.O.; Akinbola, E.T.; Ogundele, A.A.; Oyewale, J.O.24 geese (12 males and 12 females) were used to assess the effect of wallowing on the haematology and thermoregulatory response of geese at high temperature humidity index. The male and female geese were randomly divided each into 2 treatments which were the wallowed group and non- wallowed group and the experiment lasted for 5 weeks. The temperature, humidity, pulse rate, respiratory rate and rectal temperature were measured every alternate day for a period of 5 weeks while the blood samples of the animals was collected and analysed for haematological profile twice during the experiment: 2 weeks post wallowing and 4 weeks post wallowing. Significantly higher values were observed in the respiratory rate and pulse rate of non-wallowed geese than the wallowed geese for the wallowing effect. Sex did not have any significant effect on all the parameters. The values for their respiratory rate, rectal temperature and pulse rate ranged from 20.24±2.48-21.15±3.69 breaths/minutes, 40.42±0.35-40.43±0.450C and 152.74±22.32-156.33±17.43 beats/minutes respectively. Their respiratory rate and rectal temperature were also observed to be significantly higher in the afternoon and evening than in the morning. However, there was no significant difference in their pulse rate. Therefore, this study indicated that wallowing and daytime influenced the thermoregulatory response of the geese at high temperature humidity index.Item VARIATIONS IN THE THERMOREGULATORY RESPONSE OF GEESE DURING LOW TEMPERATURE – HUMIDITY INDEX(NIGERIAN SOCIETY FOR ANIMAL PRODUCTION (NSAP) 46TH ANNUAL CONFERENCE, 2021) Akinbola, E.T.; Ewuola, E.O.; Olujimi, A.T.In a 28–day trial, the effects of sex and daytime on the thermoregulatory response of geese during low temperature – humidity index was investigated. Twenty four geese (12 males and 12 females) were allotted into two treatments according to their sex in a completely randomized design. Their cloaca temperature, respiratory rate and pulse rate were measured and recorded in the morning, afternoon and evening for the entire experimental period. Also, the ambient temperature and relative humidity of the pen were recorded daily. Males had significantly (p < 0.05) higher respiratory rate (20.84±2.06 breaths/minute) than females (19.49±1.37 breaths/minute). However, pulse rate and cloaca temperature were not significantly (p > 0.05) different between the two sexes. The respective mean temperature, humidity and temperature-humidity index (THI) values recorded were 25.20±1.460C, 91.93±4.38% and 24.92±1.38 (morning); 28.98±1.870C, 73.64±9.00% and 27.74±1.37 (afternoon) and 28.88±2.300C, 72.39±8.87% and 27.60±1.86 (evening). The cloaca temperature in the morning was significantly (p < 0.05) lower than in the afternoon and evening while their pulse rate and respiratory rate were not significantly (p<0.05) different at the respective daytimes. Hence, sex and daytime independently influenced the thermoregulatory response of the geese.Item Variations in the thermoregulatory response of geese during high temperature – humidity index(Proceedings of 25th Annual Conference of ASAN, 2020) Akinbola, E.T.; Ewuola, E.O.Geese have a seasonal reproductive pattern governed by environmental fluctuation. Birds must therefore be in homeostasis with their environment for optimum performance and reproductive efficiency. In a 21–day trial, the effects of sex and daytime on the thermoregulatory response of geese during high temperature – humidity index was investigated. Twenty four geese (12 males and 12 females) were allotted into two treatments according to their sexes in a completely randomized design. Their respiratory rate, rectal temperature, pulse rate and panting rate were measured and recorded in the morning, afternoon and evening throughout the entire experimental period. Also, the ambient temperature and relative humidity of the pen were recorded on a daily basis. Results showed that females had significantly (p<0.05) higher respiratory rate and pulse rate than males. However, males had significantly (p<0.05) higher rectal temperature than the females. The panting rate was not significantly different (p>0.05) between the two sexes. The respective mean temperature, humidity and temperature-humidity index values recorded were 26.59oC, 85.65% and 40.69 (morning); 34.16oC, 46.05% and 48.25 (afternoon) and 34.39oC, 47.45% and 47.84 (evening). The rectal temperature in the morning was significantly (p<0.05) lower than in the afternoon and evening and their pulse rate decreased (p<0.05) inversely with daytime. Hence, it can be concluded that sex and daytime independently has effect on the thermoregulatory response of geese.Item Growth performance, haematology and serum biochemistry of rabbits fed varying levels and forms of cassava peel(Trop. Anim. Prod. Invest. 22 (2):35-45, 2019) Akinbola, E.T.; Aromoye, R.A.; Oladimeji, S.O.; Tewe, O.O.In a 56 – day feeding trial, performance, haematology and serum biochemistry in grower rabbits fed varying levels of conventional, coarse and fine cassava peel were investigated. Seven diets (I to VII) were formulated with varying levels of cassava peel inclusions. Twenty- eight grower rabbits were randomly distributed to the 7 dietary treatments with four animals per treatment in a completely randomized design. Rabbits fed diet I had significantly (p < 0.05) higher daily weight gain and total weight gain than those fed diet V but was comparable to others. Also, rabbits fed diet VII had significantly (p < 0.05) higher average daily feed intake than those fed diets II, IV and V but was comparable to others. Feed conversion ratio of the diets were comparable to each other except diets I and IV. The values for all the treatments ranged from 4.83 to 5.86. Significantly (p < 0.05) lower dry matter digestibility was observed in rabbits fed diets V and VI (0.73 and 0.75 respectively). Crude protein digestibility was significantly (p < 0.05) higher in rabbits fed diets I and VII than diet III, ether extract digestibility values were significantly (p < 0.05) lower in rabbits fed diets III, V and VI while crude fibre digestibility improved in rabbits fed diets II, IV and VII ( 0.67, 0.70 and 0.72 respectively). Rabbits fed diet VI had significantly lower red blood cell count (4.23 x 106/L) compared to those fed with diets III, IV, V and VII. Also, rabbits fed diets V and VII had significantly (p < 0.05) higher haemoglobin than those fed diet II. The overall value ranged from 10.10 to 12.05g/dl. Rabbits fed diet I also had significantly (p < 0.05) higher albumin compared to those fed diet IV.
