Four dietsD1, D2, D3 and D4 containing 0, 3, 4.5 and 6% inclusion levels of urea respectively and 60% maize stovers each were fed to the goats during 14 weeks feeding experiment, for digestibility trials, weighed feed was fed each day for 7 days after an initial 14 day adaptation period, urine, faecal and diet samples were collected and analysed. Results showed that crude protein (CP) content of diets increased as the inclusion level of urea increases while voluntary dry matter intake (DMI) of all nutrients by bucks, decreased significantly (P<0.05) with the increase in dietary urea. There were significant differences (P<0.05) in the apparent digestibility of crude fibre (CF) and nitrogen free extract (NFE) of diets but all other nutrients showed no significant variation (P>0.05) in digestibility. Mineral intake by bucks decreased significantly (P<0.05) with increasing level of dietary urea inclusion. The highest value of mineral retention was recorded for goats on diet D1. The inadequacy of some minerals in experimental diets may require supplementation when a urea-mixed milled maize stover (UMMS) diet is fed to goats during the dry season.

D. Adams against Escherichia coli , Pseudomonas aeruginosa , Staphylococcus aureus , Staphylococcus saphrophyticus were determined using agar diffusion method. The minimum inhibitory concentration (MIC) was determined. The minimum inhibitory concentration (MIC) was determined. The result showed that the MIC ranges from 21.3-42.5 mg, 42.5-85.0 mg and 85.0 mg for M. oleifera , A. indica and A. africana leaf extracts respectively against E. coli and S. aureus . The phytochemical screening of the leaves revealed the presence of secondary metabolites such as tannin, saponin, alkaloid, flavonoid and phenol. The secondary metabolites detected in the leaves are responsible for the observed antibacterial activity of the plant and hence, its potential use as medicinal herb in the treatment of infections caused by the test organisms.

The chemical properties of two different commercial microbial phytases (Natuphos and Ronoxyme P) ... more The chemical properties of two different commercial microbial phytases (Natuphos and Ronoxyme P) were compared. Natuphus production was based on the use of a recombinant of Aspergillus niger strain while the Ronoxyme P was from Peniophora lycii. The enzymes were studied for their optimum pH, optimum temperature and enzyme stability, resistance to protease and stability in digesta supernatants. The phytases were found to exhibit different properties depending on source of the phytase gene and production organism. An optimum pH of 5.5 was recorded for the enzyme from Peniophora lycii while pH of 5.0 was recorded for the enzyme from Aspergillus niger. Both phytases had 50 0 C as their optimum temperature. The result of the enzyme - stability in aqueous solution indicated that the Peniophora lycii phytase was more thermo-stable than the Aspergillus niger phytase. Incubation of the phytases preparations with porcine proteases revealed that Aspergillus niger was more resistant to pepsin a...

Four concentrate supplements were formulated to include 0 (MO), 15 (M15), 30 (M30) and 45 (M45) mg monensin/kg dry matter. Twenty-four WAD bucks (7.3±1.20 kg initial body weight, aged 9-12 months) were randomly allotted to four experimental diets in a completely randomised design for 90 days, six animals per diet. Results indicated that animals fed M15, M30 and M45 diets had lower (P<0.01) dry matter and water intake than those fed M0 diet. Crude protein and neutral detergent fibre intakes by the bucks followed similar trend. Animals on M15, M30 and M45 had better (P< 0.001) feed and protein efficiency ratio than those fed M0 diet. Rumen pH and total volatile fatty acid concentration were maintained (P>0.05) while monensin decreased (P< 0.001) acetate/propionate ratio. Blood glucose increased (P<0.001) from 59.1 mg/dl in animals on M0 diet to 67.8, 66.0 and 66.3 mg/dl in animals on M15, M30 and M45 diets. Overall, there were no variations among animals on M15, M30 and M45 diets. It is concluded that feeding monensin at 15 to 45 mg/kg DM of supplemental concentrate diets to West African dwarf bucks could be effective in improving feed and protein efficiency, manipulating the rumen for increased propionate production and increasing blood glucose levels.

It is a fermentation vat filled with microbial populations which collaborate to digest cellulose and other polysaccharides, producing carbon dioxide, methane and organic acids. The rumen is an anaerobic environment; i.e. no oxygen. Ingested food first enters the rumen (pH 6.5, temperature of 300C) where it is microbially digested for ~ 9 hours. The gaseous products of the microbial degradation are expelled from the animal (eructation). The material from the rumen, called the cud, is regurgitated. This regurgitated mixture of microorganisms and partially digested materials then travels through the abomasum, the omasum (pH ~ 2), and the rest of the digestive tract, for further digestion.

At the end of the study blood samples were also collected for haematological and serum assay. Results showed that the addition of C. odorata to the diets influenced (p 0.05) affected by dietary inclusion of C. odorata. Haematological parameters were not differed (p>0.05) across the dietary treatments. However, serum glucose and aspartate aminotransferase increased (p<0.05) with increase in inclusion of C. odorata. It can be concluded that t...
