“…Siddhartha, Nitscke, and Contiero (2012), posited that cassava wastes can serve as substrate for microbial processes in the production of different products that are beneficial. Although cassava tubers has become an integral part of commercial animal feed production (Omede, Ahiwe, Zhu, Fru-Nji, and Iji, 2018), smallholder farmers in the rural areas find cassava peels as a cheap source of feed for livestock production (Ekop, Simonyan, and Evwierhoma, 2019). Provide fertilizer for crops 0.64 information on cassava waste utilisation processes ( =1.61).…”

This study assessed the strategies used in cassava wastes value addition among cassava processors in Oyo State. Multistage sampling procedure was used to draw 110 cassava processors as respondents. Questionnaire was used to collect information from respondents, while data were analysed using descriptive statistics and Pearson Product Moment Correlation. Over half (57.3%) of the respondents had between 1 and 10 years of processing experience. Respondents had high knowledge on sun drying ( =0.75) and compost making ( =0.62) as cassava waste value addition strategies. Source of increased income ( =0.97) was perceived to be a major benefit of value addition. High moisture content of cassava wastes ( =1.64) and inadequate information on cassava waste utilisation processes ( =1.61) were constraints to value addition practices. Sun drying ( =1.87) and composting ( =1.68) were the most utilised value addition strategies used. Significantly related to utilisation of cassava waste value addition were knowledge on biogas (r= 0.25), composting (r=0.10), fermentation (r= 0.55) and ethanol (r=0.19). Extension agent and government should sensitize and train cassava processors on cassava waste value addition.

“…Cassava tubers have high ME; however, their inclusion in poultry diet is restricted because of their low protein content, the unbalanced amino acid profile, the high fibre content and the presence of antinutrients, partic ularly cyanogenic glucosides [4]. The antinutritional factors (ANF) in cassava can be reduced through several physical processing methods, including soaking, sundrying, boiling and ensiling [11]. Microbial enzyme supplementation has also been reported to decrease the ANF of cassava [3].…”

“…Microbial enzyme supplementation has also been reported to decrease the ANF of cassava [3]. Pro cessing cassava reduces feed wastage, improves its nutritional value and maximizes poultry production [11]. A review by Omede et al [11] suggested that wellprocessed cassava can potentially be used to replace up to 50% of maize in poultry diets without causing adverse effects on health and perfor mance of the birds.…”

Objective: Pellet durability, particle size distribution, growth response, tibia bone characteristics and energy retention were measured to evaluate cassava as an alternative energy source to replace maize in broiler diets with or without Ronozyme (A+VP) enzyme composites.Methods: A total of 480 one-day broiler chicks were randomly assigned to 8 treatments in a 4×2 factorial arrangement. Four levels of cassava: (0%, 25%, 50%, 75%) and 2 levels of enzymes (0 and 500 g/tonne) were used. Each treatment was replicated six times, with ten birds per replicate.Results: The particle size distribution in the diets showed an increasing trend of small particles with increase in cassava level. Pellet durability decreased (p<0.05) with cassava inclusion. Feed intake was highest in birds fed diets with medium cassava level at 1 to 24 d and 1 to 35 d of age. The body weight gain of birds reduced (p<0.037) as cassava level increased, but it increased (p<0.017 when enzymes were added. The feed conversion ratio was high (p<0.05) when cassava level was increased, but it reduced (p<0.05) when enzymes were added. The dressing percentage (DP), and weight of drumsticks reduced (p<0.05) with increasing cassava level. Enzyme supplementation increased (p<0.05) DP, and weight of breast, thighs and drumsticks. Ash content, weight, length, width, and bone strength decreased (p<0.05) when cassava level was increased, however, they were increased with enzyme addition. The contents of Ca, K, and Zn were raised (p<0.001) with increasing cassava level. Enzyme inclusion increased (p<0.001) all mineral contents in tibia bones. Body fat and energy retained as fat decreased (p<0.001) as cassava level increased. Enzyme inclusion increased (p<0.05) body protein content and energy retained as protein.Conclusion: Although broiler performance was depressed by high levels of cassava inclusion, it was not affected by low levels, which further improved by enzyme supplementation.

“…Cassava has been found to be a multipurpose crop that can thrive in almost every soil and be relied upon to provide the desired relief against the escalating cost of livestock feeds (Tewe, 1997). However, cassava root meals are deficient in essential amino acids such as methionine, lysine and cysteine (Motagnac et al, 2009;Omede et al, 2018). The option to improve the nutritional profile of cassava meal at reduced cost necessitated the development of composite cassava plant meal (sun-dried unpeeled tubers + leaves + tender cassava stem) as suitable replacement for maize in the diets of pigs (Akinfala and Tewe, 2001).…”

Twenty growing pigs with an average initial weight of 20.00 + 0.5 kg were randomly assigned to five dietary treatments in a completely randomized design with two replicates per treatment and two animals in each replicate. Cassava Plant Meal (CPM) prepared from sundried unpeeled cassava tubers, leaves and tender cassava stems, mixed at ratio 3:1 of unpeeled tuber meal to cassava leaf meal plus tender stem meal with the ratio of cassava leaf meal to tender stem meal as 5:1 was included in balanced rations at graded levels of 0, 25, 50, 75 and 100 percent in a fifty-six days feeding trials. The experimental pigs were weighed before and after slaughtering, dressing percent was evaluated and carcass length and back fat depth were measured on treatment basis. Meat samples were collected at the ribs (2nd and v3rd and also 12th and 13th) for cholesterol analysis. The 50 % CPM diet produced the heaviest slaughter weight. There was no significant (p >0.05) difference in the dressing percentage of pigs across dietary treatments although pigs on the control diet dressed well while pigs on 100 % CPM dressed the poorest. The 100 % CPM diet induced the leanest carcass. All the carcass and organ measurements were significantly (p <0.05) affected by dietary treatments. There was non-significant (p >0.05) influence of dietary treatments on total and high density lipoprotein cholesterol although the 50 % CPM diet produced the least and highest values respectively. Low density and very low density lipoprotein cholesterol were significantly (p <0.05) affected by dietary treatments. Replacement of maize by varying levels of cassava plant meal diets enhanced production of leaner carcass.
