Haematological values and blood urea nitrogen levels of growing Uda lambs fed forestomach digesta (FSD) and poultry litter waste (PLW) were studied. The experimental animals were randomly allotted (n=4/treatments) to diets A (20% FSD), B (20% PLW), C (10% each of FSD and PLW), D (6.67% FSD and 13.33% PLW) and E (13.33% FSD and 6.67% PLW). The experiment lasted for 84 days. Blood samples were collected prior to and after the feeding trial for haematological and blood urea nitrogen determination. Initial packed cell volume and final red blood cell counts were not significantly different between treatments (P>0.05). Initial haemoglobin concentration (HB) was similar (P>0.05) to those on treatments A, C, D, and E while final HB concentration was similar (P>0.05) for those on treatments B, C, and E. Initial and final values of neutrophil and lymphocyte counts were not significantly different (P>0.05) for all treatments. There were no traces of eosinophils at the end of the feeding trial while monocyte counts were not significantly different (P>0.05) at the beginning and end of the feeding trial. Total protein showed no significant difference in all the treatments at initial and final collections of blood. Similar results were observed for albumin and globulin concentrations. Haematological values and blood urea nitrogen were within normal values; indicating that there was no toxicity associated with the feeding of FSD and PLW alone or in mixtures to growing lambs. It was concluded that the test diets were not toxic to animals based on the haematological indices and blood biochemical parameters which were within recommended values.

A Field experiment was conducted in 2010 and repeated in 2011 cropping seasons at the Usmanu Danfodiyo University Teaching and Research Farm, Dabagi to determine the effect of intra row spacing on growth and yield of Lablab purpureus. Treatments consisted three intra row spacings (20, 30 and 40cm) laid out in a Randomized Complete Block Design (RCBD) replicated three times. The results of the trial showed that intra row spacing significantly (P < 0.05) affected stand establishment count with 20cm producing the highest (43.3)number of stands and plant height at week 3 after sowing in 2011 cropping season. Tallest plants (42.2 cm) were produced by 20cm intra row spacing. Leaf number was significant (P< 0.05) at 9 weeks after sowing in 2010 cropping season. Thirty (30) cm intra row spacing produced the highest no. of leaves (25). Leaf length was not significantly affected (P > 0.05) by intra row spacing. The longest leaf (9.9 cm) was produced by 30 cm intra row spacing. Leaf width was also not significantly affected (P > 0.05) by intra row spacing with 30 cm intra row spacing producing the widest leaf (8.9 cm). Dry matter yield was not affected (P > 0.05) by intra row spacing however, 30 cm intra row spacing produced the highest dry matter yield of 1707.7 kg/ha. It was concluded from this research that 30 cm intra row spacing produced the highest dry matter yield of Lablab purpureus (L) and is recommended for semi arid Sokoto environment.
