  A feeding trial of 84 day was conducted to evaluate the performance and egg quality characteristics of layers fed different combinations of Cassava Root Meal (CRM) and Bambara Groundnut Offal (BGO). Four layer diets were formulated such that diet T1 (control) contained 50% maize, while diets T2, T3 and T4 contained CRM and BGO in the ratios of 2:1, 1:1 and 1:2, respectively, completely replacing maize. Ninety six Shaver Brown point-of-lay pullets were allotted into four experimental groups of 24 pullets each and each group was replicated twice with eight pullets per replicate. These birds were randomly assigned to the experimental dies in a Completely Randomized Design (CRD) experiment. Results indicated that daily feed intake was significantly (p<0.05) higher for layers on diet T3 and T4 than those on diet T1. Daily feed intake was significantly higher (129.48 and 128.60 g) for layers on the diet (T1) than other treatment groups, while layers on diets T2, T3 and T4 recorded higher egg weights than those on the control diet. Hen-day production was significantly (p<0.05) higher among layers fed diet T1 (control) than those on the other treatment groups which contained different combination ratios of CRM and BGO. FCR was highest (2.11) and lowest (1.99) for layers fed diets T3 and T2, respectively. Yolk index, albumen index and yolk colour showed no statistical difference (p>0.05) in all the treatment groups. However, layers on diet T4 and T3, respectively recorded the highest (0.35 mm) and lowest (0.33 mm) shell thickness while those on diet T1 and T4, respectively recorded the highest (69.64) and lowest (60.62) Haugh units. It would appear that the different combinations of CRM and BGO significantly depressed the performance of laying birds.

  This study evaluated animal manure production, management techniques, utilization and effect on soil productivity in Amuzu Mbaise, Southeastern Nigeria. The study, which was conducted in 2006 used structured interview schedule at a phase of the study. In another phase, we studied the effects of animal manures from muturu (Local cattle), goats, sheep and pigs on a degraded Isohyperthermic Kandiudult using maize (Zea mays L.) as a test crop. The potted experiment was set up in a greenhouse using a Completely Randomized Design (CRD), with each treatment replicated 9 times. Five treatments used included manures from Muturu, goats, sheep, pigs and control. Relevant measures of central tendency and dispersion were used in the statistical analysis of socio-economic and agronomic data. Results showed that a greater number of households engaged in goats and sheep, thereby making their manures relatively more abundant than other livestock. Majority of the livestock fend for of themselves in rangelands with pigs being more confined. Animal manures were collected and used although they were inadequate and bulky while there was poor knowledge of urine as biofertilizer quality of manures differed with handing technique and manure improved maize (Zea mays L.) performance significantly (p = 0. 05). Soil chemical fertility was significantly (p = 0.05) improved. Integrated studies especially is if affects indigenous knowledge will be helpful.
