  Cockroach, earthworm and soldier ants were analyzed for their proximate compositions, minerals and phytate contents. Values for proximate composition ranged thus: cockroach (protein 9.26%; fat 21.21%; fibre 7.52%; ash 6.85%; moisture 13.85% and carbohydrate 41.33%; earthworm (protein 50.22%; fat 8.62%; fibre 1.36%; ash 26.56%; moisture 8.53% and carbohydrate 4.73%; soldier ants (protein 12.09%; fat 18.92%; fibre 20.13% ash 8.54% moisture 12.62% and carbohydrate 27.72%. Calcium was the most abundant mineral present while Cd was not detectable. The levels of phytate and phytate phosphorus were high and the samples had more than 30% of their total phosphorus linked to phytate. The Ca: Phytate molar ratios of the samples were relatively low. Based on the results it is suggested that nutritional potentials of cockroach, soldier ants and earthworm should be harnessed for use in animal feed formulation.

  Three hundred and fifty broiler chickens (Anak, 2000) were used to study the effect of partial replacement of soya bean meal (SBM) protein with cassava and or leucaena leaf meals. Diet 1 was the control diet with soyabean meal but no leaf meal. Diets 2 and 3 had 30% and 60% SBM protein respectively replaced with cassava leaf meal (CLM) protein. In diets 4 and 5, 30% and 60% of the SBM protein respectively, were replaced with leucaena leaf meal (LLM) protein. The SBM protein in diets 6 and 7 was substituted at 30% and 60% respectively with 50:50 CLM and LLM protein. The birds were assigned to the experimental diets at 10 birds per replicate and 5 replicates per treatment. The energy to protein ratios of the diets were similar. The response criteria measured were feed intake, weight gain, nitrogen retention, shank and skin pigmentation, selected carcass, organ and muscle characteristics and economics of production. The results showed that weight gain (WG, 52.1±1.00 g/day) and feed intake (134±4.37 g/day) were higher (P<0.05) in birds fed the control diets. On other diets, WG were 44.4±4.18 g (Diet 2), 43.7±2.10 g (Diet 6), 40.2±4.32 g (Diet 4), 37.2±4.13 g (Diet 3), 34.9±1.04 g (Diet 7) and 26.0±4.86 g (Diet 5) per day. Nitrogen retention was apparently highest (P>0.05) for birds on the control diet. Shanks of birds on leaf meal diets were more pigmented (P<0.05) than the control. Carcass, organ and muscle characteristics were not affected (P<0.05) by dietary treatments. Cost of feed per kilogram weight gain were similar for broiler on Diets 1, 2 and 6 ( 110, 108 and 109 respectively) and highest for Diet 5 (150). It was concluded that 30% replacement of soyabean meal protein in a 14% soyabean meal ration with cassava (10.50% of diet) or 50:50 cassava and leucaena (9.55% of diet) leaf meal protein would optimize growth performance and economic returns from broiler production especially during periods of high cost and scarcity of soyabean meal.

  Water troughs from deep litter and caged chicken water troughs (drinkers) fixed to each of the different 3-tier cages containing layer chickens in Farms A, B and C were subjected to a 7-day study which involved the monitoring of poultry farm hygiene. Drinkers were washed before filling with water on Day 1. For Days 3, 5 and 7 water was served without prior washing. The occurrence and characterization of the bacteria isolates were investigated and data obtained were analyzed and compared. For the bacterial count on Day 1, for layer chickens on cage system, no significant differences (p>0.05) among the farms and between the farms tier interactions. On Day 3, no significant difference (p>0.05) among the parameters. On Day 5, there was significant difference (p<0.05) among the farms and on Day 7, there was high significant difference (p<0.01) among the farms. On Days 5 and 7, there were no significant differences (p>0.05) among the tiers nor between the interactions of the farms and tiers. The bacterial count in water troughs of layer chickens in deep litter system, on Day 1, had no significant differences (p>0.05) between the farms, water troughs and their interactions. On Day 3, no significant difference (p>0.05) among the parameters. On Days 5 and 7, there were significant difference (p<0.05) and a high significant difference (p<0.01) between the farms respectively. On Days 5 and 7, no significant differences between the water troughs and between the interaction of the farms and the water troughs. Farm A isolates contained Staphylococcus aureus, Proteus vulgaris, Streptococcus faecalis, Escherichia coli, Staphylococcus epidermis, Klebsiella sp., Salmonella sp., Bacillus subtilis, Lactobacillus salivarius and Corynebacterium sp. Farm B had Staphylococcus aureus, S. epidermis, Bacillus subtilis, Corynebacterium sp., Escherichia coli, Streptococcus faecalis and Klebsiella sp. while for Farm C, apart from the prevalent bacteria isolates obtained in Farms A and B, additional 2 bacterial isolates, Lactobacillus salivarius and Pseudomonas aeuriginosa were found. In conclusion, water troughs when cleaned on daily basis carry minimum bacterial load. Those left for 3, 5 and 7 days uncleaned had progressively high bacterial loads, suggesting that the flock of birds and the consumers of the eggs and meat from the chickens are at risk of bacterial infection unless strict farm hygiene is ensured through regular monitoring.

  Water is the most universally used single necessity of life. To attain a safe water quality to various communities, an understanding of water microbiology and chemistry is therefore imperative. In this study, well water at different storage durations of 0, 2, 4, 6 and 8 weeks were assessed for bacteriological quality using standard microbiological techniques. Black barrel-shaped plastic containers (300 liter capacity) were used for different storage durations. Water samples at the different storage durations were collected from each corresponding containers. Sterile swabs were used to sample the sides and bottom of the storage containers to determine the prevalence of specific bacteria present in the samples. The results obtained showed that 0 week storage had the highest (100.00 CFU mL-1) coliform counts while the lowest (28 CFU mL-1) was obtained for 8 weeks of storage. Escherichia coli were not found in 4, 6 and 8 weeks old water. 0 and 2 weeks old water contained E. coli and the mean values were 1.80x104±0.03 and 1.43x104±0.01CFU mL-1, respectively (p<0.05). Salmonella organisms were found in the 0 week old water but absent in the 2, 4, 6 and 8 weeks old water. Shigella count (62.33x102±45.30 CFU mL-1) was highest in 4 week old water while the lowest (11.0x103±1.00 CFU mL-1) was found in 6 week old water (p<0.05). Zero week old water had the lowest significant (p<0.05) value of 0.35x104±0.05 CFU mL-1 for mesophilic bacteria and the highest value of 50.00x104±10.0 CFU mL-1 was recorded in the 8 weeks old water. Sides and bottom samples were contaminated with coliforms, E. coli, Salmonella and Shigella organisms. It was concluded that the variously stored well water samples were contaminated with bacteria and the values obtained were above the recommended standards by the World Health Organization (WHO).
