The objective of this experiment was to evaluate the performance and meat quality of lambs fed diets containing four levels of substitution (0, 33, 67, and 100 %) of soybean meal for detoxified castor meal (CM).
Twenty-four sheep (18.5 ± 2.71 kg initial body weight) were distributed in a completely randomized design with four treatments and six replicates.
The intakes of dry matter (DM), crude protein (CP) and metabolizable energy were not affected (p > 0.05) by the CM levels. The neutral detergent fiber (NDF) intake increased linearly (p < 0.05) and the non-fiber carbohydrates intake (NFC) had a linear decrease (p < 0.05). Final body weight and average daily gain had a decreasing linear effect (p < 0.05) with the inclusion of the CM levels in the diet. Effects of the inclusion of CM were not observed (p > 0.05) on the percentage of total lipids of the lamb meat, but the inclusion of CM in the concentrate had a positive quadratic (p < 0.05) the oleic acid (C18:01n9) in lipids of the lamb meat. Conclusions: Inclusion of detoxified castor meal in the concentrate impairs the productive performance, however it contributed to increase monounsaturated fatty acids content in the meat of lambs. Replacing up to 33% soybean meal with detoxified castor meal is recommended.
