The objective of this work was to evaluate the effects of the use of maniçoba silage (Manihot glaziovii Muell. Arg.) in different forage:concentrate ratio (30:70; 40:60; 50:50 and 60:40%) in milk composition, fatty acids profile and sensorial characteristics of Moxotó dairy goat milk. Eight multiparus goats were used, with approximately 60 days postpartum and about 44 kg on average, in a 4 × 4 Latin square design, with four treatments, four periods and 4 animals. Each period lasted 15 days : 10 of adaptation of the animals to the diets and 5 of milk collection. No effect of the diets was observed on milk chemical composition, which showed mean values of protein (3.79%), fat (3.97%), lactose (4.66%), total dry extract (13.12%), density (1.033) and acidity (19ºD). A positive linear effect was observe for the miristic acid (C14:0), with mean values from 6.15 to 7.85%, and a negative linear effect was observed for the linolenic acid (C18:3), with mean values from 2.13 to 0.76%, due to the increase of silage levels in the diet. The results of ADQ (quantitative and descriptive analyses) show that the use of maniçoba silage in goats diet did not cause sensorial perceptible changes in the milk. The maniçoba silage inclusion in feeding of milk goat up to the level of 60% in the diet did not change the composition and sensorial characteristics of Moxotó breed goat milk.
