  Poultry egg is a vehicle for reproduction; it also serves as a source of food for human consumption. The size and shape of avian eggs differs among the various species of birds, but all eggs have three main parts-yolk, albumen and shell. The quality of eggs depends on physical make up and chemical composition of its constituent parts. Due to the diversity in the potential uses of poultry eggs and the subsequent consumer demands that egg quality become extremely difficult to define. Egg quality is the more important price contributing factor in table and hatching eggs. It is obvious that quality of egg is important from producer’s point of view. One of the biggest challenges for the poultry industry is to provide consistent quality egg products to the consumer. Thus breeding companies are shifting selection emphasis to improved egg quality. Problems associated with egg quality include: egg shell defect and internal defects which can be broadly categorized into three groups namely: defects affecting yolk quality, defects affecting albumin quality and defects affecting overall quality. Egg quality defects are usually easily resolved, but can be costly if they are not dealt with quickly.

  The efficacy of wetting sun-dried cassava tuber meal as a method of reducing its hydrocyanide (HCN) content and improving its nutritive value for laying hens was investigated. Cassava tubers were peeled, chopped into pieces, sun-dried and then milled. Part of the Sun-dried Cassava Tuber Meal (SCTM) was soaked in water at the rate of 5 parts of water to 4 parts of the meal, thinly spread on the floor for 5 h and then taken out and sun-dried again. The Raw Cassava Tuber Meal (RCTM), Sun-dried Cassava Tuber Meal (SCTM) and Wetted Sun-dried Cassava Tuber Meal (WSCTM) were analyzed for HCN content. Five diets were made such that diet 1 (control) contained no cassava tuber meal; in diets 2 and 3, 50% of the maize in diet 1 was replaced with SCTM and WSCTM, respectively, while in diets 4 and 5, 100% of the maize was replaced with SCTM and WSCTM, respectively. Each diet was fed to a group of 24 laying hens for 12 weeks. At the end of the feeding trial, 4 birds were randomly selected from each group and used for determination of internal organ weights and haematological indices. Raw cassava tuber meal contained 800 ppm HCN, SCTM contained 50 ppm HCN while WSCTM contained 10 ppm HCN. The group on 100% WSCTM diet consumed significantly (p<0.05) less feed, gained least body weight and recorded least hen-day egg production, possibly due to very powdery nature of the diet. Egg weight and feed conversion ratio were not affected by the treatments (p>0.05). Egg quality indices were also not affected by the treatments (p>0.05). Internal organ weights were not affected by the treatments (p>0.05) but the birds on cassava diets recorded significantly (p<0.05) more abdominal fat. The birds on cassava diets also recorded significantly (p<0.05) less WBC and PCV values relative to the control group.

  Several processing methods have been used to reduce the cyanogenic glycoside content of cassava used in animal feeding, resulting in wide variations in the physicochemical and hydrogen cyanide (HCN) contents of available processed cassava products. This study evaluated the physicochemical and HCN contents of three differently processed cassava products used for feeding poultry in Nigeria. The three products were designated Abi (AB), Nali (NB) and Local (LB) brands. They were analyzed for their physical properties Bulk Density (BD), Water Holding Capacity (WHC) and specific gravity (SP); chemical properties Moisture Content (MC), Crude Protein (CP), Crude Fiber (CF), Ether Extract (EE) Ash Content (AC), Nitrogen Free Extract (NFE) and Metabolizable Energy (ME) and hydrogen cyanide contents. The LB and AB had significantly higher (p<0.05) WHC than NB while LB had the lowest BD and SG which were again significantly different from those of AB and NB (p<0.05), indicating significantly higher insoluble Non Starch Polysaccharides (NSP) or indigestible fiber in LB. The AB and LB were similar in their CF, AC and NFE values (p>0.05) which were significantly different from the NB values (p<0.05). The significantly higher CF (5.5%) in NB is chiefly soluble NSP as shown by the low WHC of the brand. The NB recorded very high HCN value (100-200 ppm), while the LB and AB had 5-15 ppm, indicating value in poultry feeding. Comparatively, NB, which is an oven toasted product, recorded superior physicochemical values, while the AB and LB gave more desirable HCN values. The Nali and Abi processing methods could be combined to produce a superior cassava product for the feeding of poultry in Nigeria.

  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.
