Abstract: This study was conducted to evaluate the effects of including gliricidia hay (0, 5, 10, 15, and 20% fresh matter—FM), replacing ground corn and cottonseed cake, on the quality of total mixed rations silages based on spineless cactus. Twenty-five experimental silos were distributed in a completely randomized design experiment (five treatments—five replications). Ash, neutral and acid detergent fiber, and hemicellulose contents increased linearly, whereas the non-fibrous and total carbohydrates decreased ( p < 0.05). Crude protein and ether extract contents were quadratically influenced ( p < 0.05). The pH values and acetic acid concentrations increased, whereas the lactic acid concentration decreased linearly ( p < 0.05). Ammoniacal concentration was influenced quadratically ( p < 0.05). Decreasing linear effects were observed on the maximum and minimum temperatures and thermal amplitude ( p < 0.05). A quadratic effect was observed on forage losses ( p < 0.05). Effluent losses decreased, and dry matter recovery was influenced quadratically ( p < 0.05). The inclusion of up to 15.1% gliricidia hay in the production of total mixed ration silages based on spineless cactus preserves adequate standards of chemical composition (15.6% crude protein) and fermentation profile, while decreasing forage losses (7.3% FM) without compromising dry matter recovery and aerobic stability.
