Short summary
This research was conducted to valorize crude olive cake, extracted olive cake, and olive leaves using an exogenous fibrolytic enzyme in ruminal nutrition. This additive improved only the nutritional value of crude olive cake and olive leaves. These results can encourage breeders to use this waste as feed at a low cost in animal nutrition. This valorization of waste is a good solution to reduce pollution.
