A study was conducted to determine the nutrient intake and digestibility of graded levels of maggot-upgraded poultry droppings (MUPD) in west African dwarf (WAD) rams. Three diets were formulated to contain MUPD at 0, 10, and 20% level, designated diets A, B and C respectively. Six WAD rams aged between 12 to 16 months with weight range of 7 to 9 Kg were randomly assigned to the three (3) diets in a 3X3 Latin square design experiment. The rams were put separately in metabolism cages for easy collection of faeces and urine. The feeds and faeces samples were analyzed for proximate composition, while the urine samples were analyzed for nitrogen. The crude protein and ether extract were significantly (P<0.05) higher in diets B (14.12, 4.99) and C (14.30, 4.98) than diet A (13.18, 4.59), while the NFE was significantly  Production and evaluation of Watermelon juice (Citrul/us lanatus) using different varieties (Dansuke, Orangeglo and Cream of Saskatchewan) was investigated, using single strength Orange juice as control. The samples were examined for presence of defects and weighed. The rind and seeds were removed to obtain the pulp which was cut into tiny slices and crushed to homogenize, and the juice was pressed out, and pasteurized. The sample products were analyzed for proximate, physiochemical and sensory properties. Results showed that there was a significant difference (P<0.05) in the proximate composition and vitamin contents of the samples. The watermelon varieties formed a fairly good source of vitamins A (6.94%) and C (13.73%) for Dansuke watermelon; 6.52% of Vitamin A and 11.85% of Vitamin C for Orangeglo; and 6.72% of Vitamin A and 13.52% of Vitamin C for Cream of Saskatchewan respectively. Of all the watermelon samples, Dansuke watermelon has the highest value of Vitamins, followed by Cream of Saskatchewan, then O rang egbo watermelon Minerals including potassium and calcium were Significantly different (P<0.05) with Dansuke having o.005% potassium and 0.006% calcium, Orangegb0 had 0.004% potassium and 0.0075% calcium, while Cream of Saskatchewan had 0.35% potassium and o.06% calcium respectively. Accept-" of the fruit juices was significant C(64.04) than those on diet A (50.19). the apparent digestibility coefficient (%) of crude protein and ether extract were significantly (P<0.05) higher in the diets B (54.12, 39.01) and C (55.37, 39.96) groups than the diet A (50.13, 34.12) group. Crude fibre was better (P<zo.05) digested by the diet B (43.67) group than the diet A (41.52) and diet C (42.18) groups. Nitrogen free extract had significantly (P<0.05) higher coefficient of digestion in group A (39.66) than B (33.65) and C (35.14) groups while animals in diet C had better (P<0.05) coefficient of digestion than B group. The results of this study indicated that WAD rams fed 20% dietary MUPD had higher apparent-N-digestibility and digestibility coefficient of crude protein than those fed the control diet (0%) MUPD. It is therefore recommended that the 20% level of MUPD can be incorporated in diets of WAD sheep as nitrogen source, for better utilization of nitrogen in the diets.
