The effect of replacing of 0; 0.33; 0.67 and 1.0 (kg/kg) of soybean meal (SBM) by undecorticated castor seed meal treated with calcium oxide (CMT – 60 g/kg) was evaluated on performance and efficiency of nutrient utilization in dairy cows. Sixteen Holstein and crossbred cows were distributed in four 4 × 4 latin squares. Animals received concentrated feed at a ratio of 1 kg for 3 kg of milk produced, in the natural matter. The diets had the same amount […]

This experiment aimed to determine the metabolizable energy and the digestibility of detoxified castor meal and castor cake nutrients for broilers. A total of 180 Cobb-500TM broilers from 21 to 32 days of age was randomly distributed in three treatments with six replicates of 10 broilers – 5 males and 5 females. The experimental treatments were a reference-diet and two test-diets composed of 80% of reference-diet and 20% of detoxified castor cake or castor meal. The adaptation period ranged from […]
