Trial of partial substitution of maize (Zea mays) by Parkia biglobosa pulp in the diet of japanese quail (Coturnix japonica)

Abstract
Poultry farming has always been a means of combating malnutrition. In recent years, quails farming has offered us new choices of taste, with meat production to meet the increased demand in animal proteins. However, the big problem in the poultry sector remains the cost of food. To overcome this problem, the use of agricultural by-products in animal feeding remains capital. These by-products are readily available and rich in nutrients, as it is the case with Adansonia digitata and Parkia biglobosa pulp. This is the context in which this study is taking place, which is a contribution to the valorization of P. biglobosa pulp as a partial replacement for corn in quail nutrition as a source of energy and nutrients. A total of 540 curds was selected with an average body weight of 7.00 ± 0.02 g and one day of age. Four batches of treatments were constituted, namely, batch control, batch 5%, batch 10% and batch 15% according to the rates of substitution of corn by P. biglobosa pulp in their feed. The weekly weighings of the birds made it possible to follow their weight growth and the average weekly gain of the birds. The consumption index was thus determined on the basis of food consumption. The results showed that the substitution of maize by P. biglobosa pulp improved the weight and the average daily gain of the birds in the growth phase. Feed consumption and feed conversion ratio were low for the control batch compared to the treated batches during both rearing phases. Food consumption and the consumption index were more in favor of the control especially in the start-up phase compared to the treated batches. The pulp of P. biglobosa, by virtue of its nutritional quality, can therefore be used in quail feed at corn substitution rates of 5 to 15% without adversely affecting its zootechnical performance.
