A study on haematology and serum biochemistry of wattled and non wattled Red Sokoto does and their offspring *Kolo, P. S., Otu, B., Banjo, A. A., and Kolo, H. N. Department of Animal Production, Federal University of Technology, Minna, Niger State, Nigeria. Corresponding author: kolo.philip@futminna.edu.ng; +2347035071871 Wattle is of utmost ornamental importance for courting potential mates and influencing thermoregulatory mechanisms which help the animal adapt to the environment. It also provides information on relationship between haematological and serum biochemical parameters. A study on haematology and serum biochemistry of wattled and non wattled Red Sokoto does and their offspring was carried out at the Teaching and Research Farm of the Department of Animal Production, Federal University of Technology, Minna. Fifty (52) Red Sokoto goats comprising of thirty-two (32) does four (4) bucks and sixteen (16) weaned kids managed semi-intensively were used for the study Blood samples were collected using 5 ml syringe and 22-guage needle from the jugular vein. 5 ml of blood was collected from each goat used out of which 2.5 ml was dispensed into Ethylene Diamine Tetra Acetic Acid (EDTA) bottle while the remaining 2.5 ml was dispensed into plain (anticoagulant free) bottles and labelled properly according to the treatment group. Data collected were analyzed using SAS statistical package. It was observed: that wattle had significant effect (p<0.05) on Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC), White Blood Cell (WBC), Sodium, Potassium, Calcium, Chloride, Phosphorus, Cholesterol, Total Protein, Low Density Lipoprotein (LDL) and Total Bilirubin of Red Sokoto Does but had no significant influence on the haematology and serum biochemistry of wean Red Sokoto kids. Does in T had the highest MCH values of 63.50 mmo/l while treatments T1 3 , T2 and T4 had values of 23.00 mmo/l, 33.00mmo/l and 34.00mmo/l respectively. Also Does in T2, T3 and T4 recorded higher calcium levels of 2.54mmo/l, 2.56mmol/l and 2.61mmo/l) respectively compared to values of 2.29mmo/l recorded in T1. These relevant influence of wattle therefore should suggest the deployment of deliberate effort to preserve the wattle gene to prevent the goats carrying the gene from going to extinction.
Carcass yield and haematological indices of broiler chickens fed diets containing varying levels of dried watermelon rind (DWMR)
(Nigerian Journal Animal Science, 2021) Banjo, A. A.; Otu, B. O.; Kolo, P. S.; Kolo, H. N.; Omolola, B.; Sajoh, M
150 day old unsex broiler chicks were used for the experiment to determine the effect of replacement of wheat offal with dried watermelon rind on the carcass yield and haematological indices of broiler birds. The chicks were randomly distributed into five treatments with each treatment having three replicates with ten chicks per replicate. Carcass yield and haematological indices were conducted in a completely randomized design comprising five dietary treatments such that T1 was served as the control, T2 were fed 25% DWMR replacement, T3 had 50 % DWMR, T4 had 75 % DWMR and T5 were given 100 % DWMR. At the end of the eight weeks, three birds from each dietary group were sacrificed to estimate the dressing yield and relative weight of organs (liver, heart and gizzard) while blood was collected for haematology and serum biochemistry analysis. Data collected were subjected to analysis of variance (ANOVA). Replacement of wheat offal with DWMR significantly (p<0.05) improved the thigh, back, heart and lungs characteristics whereas it did not significantly (p>0.05) influenced the live weight, slaughter weight, eviscerated weight and other primal cut parts. RBC and MCHC were significantly (p<0.05) affected. It can be concluded from this study that DWMR can be included in broiler chickens diet with no negative effect on the carcass characteristics and serum indices
EFFECT OF AQUEOUS EXTRACT OF WATERMELON PULP ON THE MORPHOMETRIC CHARACTERISTICS OF RABBIT (Oryctolagus cuniculus) REPRODUCTIVE TRACT
(Journal of Arid Agriculture, 2024) Kolo, P. S.; Adama, J. Y.; Obi, C.C.; Dikko, A. H.; Kolo, H. N.; Abubakar, M. B.
The effect of aqueous extract of watermelon pulp on the morphometric characteristics of 40 matured mixed breeds of rabbit about 1200-1400g (comprising of 20 bucks, 20 does) reproductive tract was investigated. Watermelon pulp extract was at zinclusion levels of 0, 5, 10, 15 and 20 g per 80-ml of water. The rabbits were randomly allocated to five treatments comprising of four replicates per treatment at two rabbits per replicate making eight rabbits per treatment in a completely randomized design. Feeds were given ad-libitum for twelve weeks and water was provided daily for 20 hours while for the remaining hours of the day (4 hours), they were deprived of water so that they can take of the treatment dosage. At the end of the experiment, 4 rabbits (2 bucks and 2 does) were randomly selected from each treatment. The animals were sacrificed and eviscerated for reproductive organ weight determination. Data obtained were subjected to the analysis of variance (ANOVA) following completely randomized. design. Duncan’s Multiple Range Test, Duncan (1955) was used to determine the significant differences (p<0.05) among treatments means. The experimental results showed that the inclusion level of aqueous extract of watermelon pulp at 5 g per 80-ml of water produced the best performance in terms of reproductive organ weight and length for both the rabbit bucks and does. From the results obtained it is observed that inclusion of aqueous extract of watermelon pulp at 5 g per 80-ml water will lead to increased productivity in rabbit breeding programmes, however higher levels may result in decrease performance and should not be encouraged.
Microbial Evaluation Of Boiled Eggs Sold In Retail Outlets In Zaria, Nigeria.
(International Conference of Agriculture and Agricultural Technology, 2019-04-21) Kolo, H. N.; Okolocha, E. C.; Samuel, F. U.; Kolo, P. S.; Banjo, A. A.; Ewa, C. E.; Azeez, S. O.
One hundred and fifty samples of boiled eggs were collected from three designated sampling areas in Zaria, Nigeria, for the isolation of Escherichia coli and Staphylococcus aureus, widely known to be contaminants and in some cases pathogens in readyto-eat foods. Total aerobic plate count was carried out using nutrient agar. The total aerobic plate count ranged from 1.0 x 109 to 7.1 x 1010 cfu/g. The average aerobic plate count was 1.8 x 1010 cfu/g. The samples were inoculated on Eosin Methylene Blue (EMB) and staphylococcus 110 agars and the susceptible isolates were subjected to standard biochemical tests and pathogenicity tests for proper biochemical characterization and identification of the pathogens respectively. The results showed that out of 7 suspected isolates of Escherichia coli and 9 of the suspected Staphylococcus aureus isolates, there were no Escherichia coli confirmed in all 7 (100%) isolates and 9(100%) was confirmed as Staphylococcus aureus. Therefore, the work shows that boiled eggs can be contaminated and that unsanitary, and unhygienic practices, during preparation and presentation especially cracked shell eggs for consumption can pose serious health hazards.
Semen Characteristics Of Rabbit Bucks Fed Graded Levels Of Newbouldia Laevis Leaf Meal.
(International Conference of Agriculture and Agricultural Technology, 2022-12-12) Kolo, H. N.; Abdulraheem, B. O.; Otu, B. O.; Kolo, P. S.; Banjo, A. A.; Dikko, A. H.
This study evaluated the effect of Newbouldia laevis leaf meal on the semen characteristics of Rabbit bucks. Twenty four rabbit bucks of 5-6 months old weighing 1.44 kg – 1.96 kg were acclimatized and allotted randomly into four treatments: T1 (control), T2, T3 and T4. The crude protein was set at 16% with inclusion levels of 0 %, 2.5 %, 5 % and 7.5 % Newbouldia laevis leaf meal respectively for12 weeks. Semen samples were collected and evaluated fortnightly for semen volume, semen motility and semen concentration. The mean values of semen volume and semen motility of rabbit bucks was not significantly (p>0.05) different across all the groups. The mean values for semen concentration of T4 was significantly (p<0.05) different from the controls. It was concluded that Newbouldia laevis leaf meal improved the testicular functions of rabbit buck.
