The objective of this study was to evaluate the production, composition and sensory characteristics of dairy goat milkfed diets containing extruded food-based castor meal (EFCM). The average values of milk urea nitrogen (MUN) wereaffected (P <0.05), and the concentration of the butyric acid content in fatty acids (C4: 0) and caprylic (C8: 0) wereaffected (P <0.05) when compared to the control treatment.For the atherogenicity index (IA) showed a significant effect(P <0.05), demonstrating best results in 33% replacement level. The variables characteristic odor, strange odor,characteristic taste, strange taste, rancid flavor, sweet taste and overall acceptability were affected (P<0.05), withaverages of 3.24, 2.88, 5.20, 3, 86, 3.49, 4.10 and 4.36% respectively. The (EFCM) can replace soybean meal up to 33%in the diet of lactating goats without causing damage to production, physical and chemical composition, fatty acidprofile of milk and their sensory qualities, then being an alternative power source for lactating goats.
