Recovery of Crop Residues in the Feed of N'Dama Dairy Cows in Periods of Last Food in Modiya Urban Commune of Faranah

Abstract

In order to evaluate the effects of supplementation of N'Dama dairy cows through potato vines (V1 = 366 kg) and rice straw (V2 = 366 kg) in times of scarcity, a trial was set up in Modiya, from March 3 to April 28, 2023 with 18 dairy cows from the 4th and 5th lactation divided into three (3) variants (V0; V1 = supplemented with potato vines; V2 = supplemented with straw rice) with (3) repetitions (R1, R2, R3) in a random block with simple classification. Each animal received its supplementary ration once a day after milking. A weekly milk sample for eight (8) weeks provided the average production: V0 = 13.67; V1 = 16.20 and V2 = 18.44 liters. A chemical analysis of the milk gave the protein and fat levels which are respectively for V0: 4.48 and 3.20%; V1: 7.10 and 3.90%; V2: 5.60 and 3.89 %. The results show that in Modiya supplementation increased the quantity and quality of the milk of the cows which received the supplement compared to the control group.
