Abstract
Assessment of the Reproduction Performance of Gobra Zebu Females and F1 Crossbreeds after Artificial Insemination in Traditional Environment in the region of Thies (Senegal). This study was carried out from October 2007 to March 2009 on 237 Gobra zebus after an insemination campaign in the area of Thies (Senegal) where it aimed at evaluating the performance of Gobra females and their products after artificial insemination. The rate of gestation was 44.3% (n=105) with an average pregnant period of 289±6 days. The rates of birth (total number of cows having calved on total number of inseminated cows), prolificacy (total number of crossbreed born on total number of kidding cows) and abortion (total number of aborted cows during the period of pregnancy on total number of pregnant cows) were respectively 34.6 (n=82), 106, and 21.9% (n=23). The rate of abortion was significantly influenced by the Body Condition Score (BCS) at the day of the diagnosis of gestation (p
