Abstract: 

The study of the effects of Acacia albida pods on the in vitro digestibility of maize stovers enriched with molasses was carried out in May 2018 in the Animal Nutrition and Production Research Unit of the University of Dschang. Bovine ruminal liquid, energy source (maize stovers enriched with 5% pods) associated with polyethylene glycol or not were used in this study. At the beginning of the test, sample of various rations containing maize stovers, pods incorporated at different levels (0, 10, 15 and 20%), and associated to polyethylene glycol (PEG) was dried and crushed in order to determine the mineral, chemical digestibility. The results of this study showed that the pods induced an increase in total nitrogen content (5.88, 6.80, 7.10 and 8.52% DM) of maize stovers with respect to the treatments. The digestibility of organic matter (35.43, 35.55, 35.85 and 37.10% DM) and digestible nitrogen matter content (4.68, 5.47, 5.76 and 6.97 g/100 g pods in maize stovers respectively in the proportions of 10, 15 and 20%. With the exception of rations containing 20% and 10% of Acacia albida digestibility parameters improved in different rations. The presence of PEG made it possible to obtain the best productions of gas (33.92 ml/500mgMS), of volatile fatty acid (VFA) (0.72mmol/40ml), of IVDOM (48.56%) and metabolizable gDM) with the ration containing 10% of Acacia albida pods in spite of the digestibility with the increasing incorporation rates of pods in pods to maize stovers enriched with 5% molasses increase the nutritional value and improves the digestibility in ruminants.
