Comparative study of some zootechnical characteristics in Baoule, N'Dama and Zebu cattle breeds in the Central region of Cote d'Ivoire. [French]Original Title Etude comparative de quelques caracteristiques zootechniques chez les bovins Baoule, N'Dama et Zebu dans la region Centre de la Cote d'Ivoire.

摘要

The indigenous trypanotolerant cattle (Baoule and N'Dama) of Cote d'Ivoire are neglected by farmers who prefer Zebu cattle which are supposed to have a big size. Farmers estimate that Baoule and N'Dama breeds are not productive due to their relative small size. The aim of this study aim was to compare zootechemical performances of Baoule, N'Dama and Zebu cattle. Productive data was collected in 105 herds including; 40 herds of Baoule breed, 31 herds of N'Dama breed and 34 herds of Zebu cattle in the Central region. The average weights (22,50 kg at birth, 184,32 kg at weaning and 335,28 kg at mature age) of Zebu Cattle were significantly higher than the average weights of Baoule and N'Dama breeds. The Baoule breed presented the lowest average weights (12,18 kg at birth, 98,63 kg at weaning and 178,55 kg at mature age). Moreover, the daily weight gains are significantly above those of indigenous taurine cattle. These significant differences could be a major advantage in any crossbreeding program including Zebu cattle and indigenous cattle.
