Abstract
A study on the laying
performance and egg quality of laying hens fed feed containing cassava peel
flour was carried out at the experimental farm of the livestock production
program of the National Agronomic Research Center in Bouake. To obtain this,
150 hens of 20 weeks of age and an average weight of 1471 ± 14 g were randomly
distributed into 15 boxes of 3.6 m² with 10 hens per box in triplicate. They
were fed twice a day with four foods containing respectively 0, 10, 20 and 30 %
cassava peel flour and a fifth commercial control food with a ratio of 110 g
per hen. After 52 weeks, the zootechnical parameters, feed consumption and
quality of the eggs produced were recorded. The results showed that up to 30 %
incorporation of cassava peel flour into the laying hen’s feed there is no
effect on hen mortality. However, the laying rate and egg production cost were
negatively affected after 20 % incorporation. The average weights of the
components (yolk, white and shell) of the eggs, the thickness of the shells and
the shape indices were not affected regardless of the rate of incorporation of
cassava peeling flour into the food. At the end of this study, cassava peel
flour can be efficiently introduced into the diet of laying hens at a rate of
20 %.

Introduction
In Côte d'Ivoire, poultry production has increased significantly in recent years, but the underexploitation of local inputs makes Ivorian poultry farmers dependent on external industries (Bamba et al., 2023). Indeed, feed alone constitutes, in poultry farming, 70% of production the cost. In this food, energy is an essential factor. However, the main energy source used in the production of monogastrics in general and chickens in particular, is maize (Atchadé et al., 2019). It covers 70 to 90% of energy needs (Archimedes et al., 2011; Atchadé et al., 2019).
However, the fluctuation of the price according to the seasons and
the times of shortages of this commodity (Kambashi et al., 2010) constitute a
constraint on the development of poultry farming. In order to reduce
food-related production costs, the development of costeffective food formulas
that integrate local, unconventional, available and low-cost food resources is
needed. One of the local agricultural by-products that can be used in animal
feed and is available in large quantities in Côte d'Ivoire is undoubtedly
cassava peelings (Kouadio et al., 2019). Indeed, cassava, from which the
peelings are made, is grown in all the agroecological zones of the national
territory with an estimated production of 4.54 million tons in 2016 (FAO,
2019). In addition, peelings account for up to 20-35% of the total weight of
the processed root (Oghenejoboh et al., 2021). It is a by-product of cassava
that has already been successfully used in broiler feed (Kouadio et al., 2014).
Thus, its use, with a substantial reduction in the use of maize in the feed,
would contribute to significantly reducing the cost of feed for laying hens and
that of the eggs that will be produced. It is in this context that this study
was undertaken. The objective of this study is to evaluate the zootechnical and
economic performance and physical characteristics of eggs from laying hens fed
with feeds containing increasing levels of cassava peel meal.
