The proximate, minerals, and phytochemical composition of Ocimum gratissimum plant (OGP) that grew with different manure were investigated. OGseeds were planted in experimental plots in a Randomized Complete Block Design (RCBD) laid out in Oyo State College of Agriculture, Igboora with three replicates having plot size 3 m x 3 m of four treatments namely; Treatment A-No fertilizer or manure -(control), B-Poultry manure, C-N:P:K 15:15:15 and D-Compost manure respectively. Other parameters studied were planted height, leave areas, number of leaves and plant girth. The pre-soil test carried out indicated that the soil had organic matter (OM) content of 1.56%, total N 0.11% and available P 16.92 mg/g. This low level of nutrients justified the need for fertilizer Original Research Article
The study evaluated the growth performance and carcass characteristics of weaned rabbits fed varying levels of undigested/unfermented and lye digested/fermented cocoa pod husk meal in different diets as a source of fibre. A Completely Randomised Design (CRD) was used which comprised of forty unsexed weaned New Zealand and Chinchilla cross rabbits which were randomly allotted into five treatments A, B, C, D and E. Each treatment consisted of eight replicates. Treatment A served as the control diet (without CPHM), B and C had 30% and 40% unfermented CPHM while D and E contained 30% and 40% lye digested\fermented CPHM respectively. Freshly broken cocoa pod husk were collected from a fermentary unit of the Cocoa Research Institute of Nigeria (CRIN) and processed. A known quantity was sundried into a constant weight before milling while the other part was soaked in lye water for one hundred and twenty hours (digested/fermented) i.e five days before being sun dried into a constant weight and milled. The milled unfermented and digested/fermented CPHM were incorporated into the experimental diets at 30% and 40% inclusion levels. The study showed that rabbits fed Diets D and E had significantly (p<0.05) higher body weight gain, feed intake, water consumption and Feed Conversion Ratio (FCR) than those fed diets B,C and A. Rabbits in A (the Control) scored lowest in all the parameters. The carcass analysis also showed that the eviscerated weight, hind limbs, fore-limbs, back and tail weight of rabbits on diets D and E were significantly higher in weight (p<0.05) than those on diets A, B and C. There was no death attributable to CPHM in the diet, therefore, fermented CPHM is recommended as fibre inclusion in rabbit diet in the tropics.Key words: Rabbits, Cocoa Pod Husk Meal, Lye, growth performance, carcass characteristics
Matured leaves of Ocimum gratissimum were harvested and the extracts used to cure Suya (an intermediate moisture meat). O. gratissimum leaves were collected from Oyo state south west region of Nigeria, rinsed in distilled water and squeezed to extract the fluid. The meat used was Semi membranosus muscle from beef carcass, which was trimmed of all visible fat and connective tissues. The meat cut was sliced into sheets of 0.18cm-0.35cm thick and lengths of between 5.0cm-7.1cm. The study comprised five treatments with 10 replicates each in a completely randomized design. Treatment A (TA) served as the control (Suya without O. gratissimum extract(OGE), while treatment B (TB),treatment C (TC), treatment D (TD) and treatment E (TE) were Suya soaked in OGE for ½ hr, 1hr, l½ hrs and 2 hrs, respectively, before coating with Suya ingredients. A total of 50 sticks of Suya weighing from 38.10 - 59.30 grams of sliced meat per stick were prepared for each treatment. The meat on sticks was properly coated with Suya ingredients and arranged around glowing embers of charcoal. The morphological and biochemical characterization of aerobic bacteria, coliform and lactic acid isolates from the five treatments was carried out. At Day 0, isolates from samples of the five treatments include: Aerobic species of Pseudomonas, Bacillus, Micrococcus, and Flavobacterium species. Three Coliform species isolated were: Proteus, Aeromonas and Enterobacter species. The four Lactic acid bacteria isolated were Pediococcus, Streptococcus, Lactobacillus species and Enterococcus feacalis. The bacterial count on Suya meat soaked in OGE at different curing times of ½ hr, 1hr, 1½ hrs and 2hrs differed. The aerobic counts (0.001x105-2.2x105) were relatively low at the third and fifth days for TC, TD, and TE while for Lactic acid bacteria, the count reduced from 3.0x105 in TA to 0.2x105 in TE. Coliform counts of 6.0x105 and 7.0x105 recorded at day 7 for TA and TB were exceptionally high. O. gratissimum extract, used as a curing agent in suya production significantly reduced the aerobic count of treated meat, thus enhancing the keeping quality of the products.
Blood reflects the pathological status of animals exposed to toxicants and other conditions. Blood examination helps to clinically investigate the presence of metabolites and other constituents in the body of animals and plays vital roles in the physiological, nutritional and pathological status of animals. Blood constituents change in relation to the physiological status of an animal.A total of 144 one-day-old Isa-brown pullet chicks were randomly picked from a larger flock, weighed and distributed to groups with 4 replicates of 9 chicks each in a completely randomized design (CRD). Four feeds were formulated to meet the NRC requirement and allotted one each to the 4 group of birds. T1 was the control, T2, T3 and T4 contained 2% of Moringa oleifera, Ocimum gratissimum and Vernonia amgydalina leaf meals respectively. At the end of the experiment which lasted for 8 weeks 2 birds were randomly selected from each replicate for haematological and serum boichemical examination. All the haematological parameters measured were not significant (P>0.05) except eosinophils while for serum biochemistry cholesterol and albumin to globulin ratio were significantly affected by dietary treatment ( P<0.05).The highest value (3.50 % eosinophils) was observed in the birds on diet 4 which had 2% of Vernonia amgydalina leaf meal and these birds also had the lowest (139.25 mg/dl) cholesterol value. It was therefore concluded that 2% of these leaf meals especially of Vernoniaamgy dalinacanbe incorporated in the diets of pullet chicks to reduce their blood cholesterol and boost the immunity
