摘 要：Both quantitatively and qualitatively, underfeeding materialized by underconsumption of meat remains one of the things most felt in Africa. To make up for this deficit, emphasis is placed on the production of short-cycle animals such as poultry, rabbits and pork. Among these animals, pig plays a very important socio-economic role in the life of local populations. Its meat is required in various ceremonies such as the dowry and funerals. For this purpose, twenty four males cross piglets with Large White × Landrace × Duroc × Pietrain phenotypic traits, aged between 58 and 62 days and having an average weight of 9.978 ± 1.11 kg were used to evaluate the influence of graded levels of bovine rumen content on the growth performances of grower finisher pigs. The piglets were submitted to 4 treatments, housed in pairs and fed ad libitum with a diet containing 0, 5%, 10% and 20% bovine rumen content. The trial which lasted for 18 weeks was carried out at the Teaching and Research Farm of the University of Dschang. The results showed that drying process destroyed most microbes found in the rumen content. These results also showed that the incorporation of bovine rumen content in diets had no significant (p 0.05) effect on feed conversion ratio efficiency. However, feed intake, body weight and body weight gain were significantly higher in pigs fed with a diet (R5) containing 5% of bovine rumen content. Feed cost per kg of live body weight was significantly (p 20 diet compared to the animals receiving the control diet which was lower than that of the other two diets (R0) and (R5) but comparable with animals fed diet R10. The analysis of the carcass showed that increasing incorporation level of bovine rumen content in the diet reduces abdominal fat and back fat thickness. For offal, the lowest weight was recorded in animals fed the control diet (R0) and the highest weight with animals fed a diet containing 5% bo
