The Use of Cassava, Sweet Potato and Cocoyam, and Their By-Products by Non – Ruminants

Abstract

As the search for alternative sources of energy for non ruminants continues, this review was undertaken to examine the potential value of cassava (Manihot utilissima Pohl.), sweet potato (Ipomea batatas Poir.), cocoyam (Xanthosoma sagittifolium Schott.) and their by-products as dietary supplements for non ruminants. Studies on these roots and tubers showed that, on a dry-weight basis, contained 2.0 -7.9% crude protein, 0.3 -3.1% crude fib re and 72.4 -77.9% starch. The practical use of these roots and tubers in non ruminant feeds is generally low. Th is level of utilizat ion is attributed to the low protein and dry matter and the potentially to xic cyanogenic glycosides in fresh cassava and irritating substance in cocoyam. Processing techniques such as fermentation, soaking, boiling, ensiling and sun-drying are adopted to remove the deleterious substances, and effects on animals. The co mparable performance of pigs and poultry fed vary ing levels of roots and tubers and their by-products with those maintained on maize showed that they can be used as substitutes in non-ru minants diets at certain levels without detrimental effects. To achieve increase in the use of these root crops and their by-products for maize replacement in intensive non-ruminant production systems, adequate protein supplementation and proper processing are essential.

Agronomic characterization of sweet potato accessions

Peel meals as feed ingredients in poultry diets: Chemical composition, dietary recommendations and prospects

“…Edache, Yisa, and Okpala () reported improved egg production egg qualities and higher economic return in laying quail hens fed 200 g/kg dietary yam peel meal. Inclusion of 200 g/kg sweet potato peel in the diet did not compromise the performance of laying hens (Apata & Babalola, ). Recently, Edache, Tuleun, Yisa, and Muduudtai () observed no differences in feed intake, egg production and qualities between laying quails fed sweet potato peel at 190 g/kg diet and the control diet.…”

Potencial Quantitativo E Qualitativo De Genótipos Batata-Doce

“…Segundo Apata & Babalola (2012) as plantas de batata-doce possuem boas qualidades nutricionais, sendo superiores a outras fontes utilizadas para a alimentação animal, e consequentemente, tem potencial de utilização na alimentação de animais ruminantes e não-ruminantes. Para a atividade normal das bactérias ruminais são necessários de 6 a 8% de proteína bruta (FIGUEIREDO et al, 2012).…”
