  Two cultivars of Panicum maximum (cultivars T58 and Ntchisi) were evaluated to determine the influence of soil type(texture and class) on their mineral and feeding values. The grasses were planted at two different locations on the farm site. Results shows that those planted on the sandy loam soil performed best. The grasses were not able to withstand the presence of clay at all. The number of tillers produced in the sandy clay soil was lower (4,250 kg ha 1) than the one in the sandy loam soil (5,826.5 kg ha 1). The presence of clay influenced the minerals present and especially made most other minerals not really available to the plant. The soil types affected the grass feeding value. The pH of the soil had no influence on the dry matter productivity of these grasses, but determined the level of acidity or basicity of the soil and had a direct link to the type and available minerals at any particular time.

  Experiment were conducted to evaluate the nutritive of 15 forage legumes collected from 5 locations Ogbomoso local government area of Oyo state in Nigeria. Analysis carried out for macro and micro-mineral contents of these plants showed high percentages of Mg (0.31), P (0.28), Ca (1.25), Na (0.02) and K (2.44). Overall mean levels were 23.64 ppm for Zn, 315.66 for Fe, 86.42 for Mn, 9.43 for Cu and 108.90 for Se. In all forages the concentrations of physic-acid (28.55-316.22mg g-1), physic-phosphorus (20.1792.50 mg g-1), oxalates (0.540.82) and nitrates (0.13-0.66%) were moderate to high. Saponin and hydrogen cyanide contents were inherently low or low due to a high drying temperature of the samples. Tannin acid differed considerably among the different species, being absent or low in some forages and extremely high in others. These differences may be genetic or due to cultural practices and soil composition. The nutritional implications of the results are discussed.

  Panicum maximum cv T58 was established on a three Nitrogen (0, 100 and 200 KgN ha-1) and spacing (50x50, 75x 75 and 100x100 cm) regimes in factorial arrangement using randomized complete block and split plot designs. The three nitrogen levels were the main treatments while the spacing was the sub treatments each replicated three times. Dry matter evaluation was done and nutrient quality analyzed after 8 weeks of planting. The harvested grass was fed to twenty-seven West African Dwarf Sheep in nine treatments with three replicates each. Feed intake, weight gain, feed digestibility, feed utilization and feed to gain ratio were parameters measured. From the results, animals on the 200 KgN ha-1/50x50 cm plot with a crude protein of 11.8% had the highest feed intake, weight gain and utilization values. The lowest were recorded for the 0KgN ha-1 treatment (5.2% CP). The 100 KgN ha-1/50x50 cm (10.8% CP) and 100 KgN ha-1/75x75 cm (8.6% CP) were not significantly different (p<0.05) in performance when compared to the 200 KgN ha-1/50x50 cm spacing (11..8% CP) and 200 KgN ha-1/75x75 cm spacing (9.6% CP), respectively. The phosphorus level followed the trend for the nitrogen level in all grass samples, which affected the acceptability level. Therefore, Panicum maximum cv T58 can be established on a 200 KgN ha-1/50x50 cm or 100 KgN ha-1/50x50 cm or on the 75x75 cm spacing and feed at 8 weeks for optimum animal production in the derived savanna zone.

  Panicum maximum cv T58 was evaluated in the derived savanna zone of Nigeria for its yield and nutritive value when fed to the WAD sheep. The agronomic experiment was a split plot design with fertilizer Nitrogen levels (0, 100, 200 and 400 KgN/ha) as main plots. Each was replicated thrice and cutting intervals (6 and 8 weeks) served as sub plots. Grasses harvested at both the 6th week and 8th week after planting were fed to the 8 WAD sheep in a latin square design for the digestibility trials which lasted 21 days. Feed intake and weight gain of the animals were recorded at the beginning and end of the trails. Animals on the 200 KgN/ha fertilized grasses at 8 weeks gained an average of 2.1 g/day after consuming an average of 1.3 KgDMY per day. They had a CP digestibility of about 89.1%, which was significantly different (p<0.05) from the control that had 79.7% CP digestibility. The animals on the control gained about 0.04 g/day after consuming an average of 0.9 KgDMY/day. Mineral content except for copper increased in significant proportion (p<0.05) as the nitrogen level increased in the soil. The increase in the phosphorus level might be responsible for the higher feed intake recorded for animals on the 200 KgN ha-1 grass plot since it increased the palatability and acceptability level. Proximate analysis of the grass revealed a crude protein value of 6.9, 9.2, 12.8 and 13.1% CP for 0, 100, 200 and 400KgN ha-1 respectively at 8 weeks. The 6-week cutting had 5.5, 7.5, 9.2 and 10.1% crude protein values for the different treatments, respectively.
