Five diets were formulated with forage cactus asthe main ingredient, with varying Guinea grass inclusion ratios: 0,10, 20, 25 and 30% on a dry matter basis. The experimentaldesign used was a completely randomised design with a factorialarrangement and three replicates. The silages had pH values ofapproximately 4.0. Lactic acid bacteria were predominant in allsilages, and this predominance increased after 7 days of ensilingin all diets, ranging from 8.0–10.1 log10 cfu g−1of silage. Silageswith 10% and 20% guinea grass showed aerobic deterioration,while the others remained stable throughout the aerobic stabilitytest. Guinea grass in combination with forage cactus can beadded in total mixed ration silages up to a level of 30%, withoutcompromising the chemical composition, silage losses orfermentative profile. However, considering aerobic stability, theaddition of 10% and 20% guinea grass resulted in greaterdeterioration after 48 h of exposure to air.  aAnimal nutrition  aForage  aInorganic acids  aMegathyrsus maximus  aSheep  aÁcido Orgânico  aCapim Colonião  aConfinamento  aEnsilagem  aForragem  aNopalea Cochenillifera  aNutrição Animal  aOvino  aPalma Forrageira  aPastagem  aSilagem  aAlternativa nutricional  aPerfil de fermentação1 aSANTOS, E.
