Ingestion et digestibilité in vivo du Panicum maximum associé à trois compléments: tourteau de Jatropha curcas, tourteau de coton (Gossypium hirsutum) et Euphorbia heterophylla chez le cobaye (Cavia porcellus L.)

The Intake and the in vivo Digestibility of Panicum maximum Associated with Three Supplements: Jatophra curcas Cake, Gossypium hirsutum Cake and Euphorbia heterophylla (Euph) in Guinea Pigs (Cavia porcellus L.). The intake and the in vivo digestibility of Panicum maximum associated with three supplements: Jatropha curcas cake, Gossypium hirsutum cake and Euphorbia heterophylla (Euph) in guinea pigs (Cavia porcellus L.) pigs, its association with Panicum maximum could be popularized wherever its abundance has been reported. In order used weed Euphorbia heterophylla in guinea pigs diet, comparative study of the intake and the in vivo digestibility of four treatments, Panicum maximum (Pan), Panicum maximum and Gossypium hirsutum cake (Pancoton), Panicum maximum and Euphorbia heterophylla (Paneuph) and Panicum maximum and Jatropha curcas cake (Panjatro), in male guinea pigs were conducted in Yamoussoukro (Ivory Coast). The means of the intake (g DM/d) were 64.8 ± 12.5; 74.3 ± 12.9; 73.7 ± 17.8 and 69.1 ± 12.3 respectively for Pan, Pancoton, Paneuph and Panjatro. Pancoton and Paneuph were significantly better ingested than Pan and Panjatro. Euphorbia heterophylla was significantly better ingested than the other two supplements (P< 0.05) and the mean daily weight gain with its association with Panicum maximum of 3.1 ± 0.6 g/d. The rate of substitution of Panicum maximum by Euphorbia heterophylla was nearly to one (1). The apparent digestibility coefficients (ADC) for dry (68.0 ± 10.5%) and organic matter (84.1 ± 5.2%) of Paneuph were significantly higher (P< 0.05) than the ADC's for the other three treatments. Given the nutritional value of Euphorbia heterophylla in guinea pigs, its association with Panicum maximum could be popularized wherever its abundance has been reported.
