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 […]

The objective was to determine the voluntary intake and digestibility of DM, OM and nutrients (CP, GE, NDF, ADF, CT, NSC and EE). And nitrogen balance of diets containing maniçoba maniçoba (Manihot glaziovii Muell. Arg.) hay Twenty-four Santa Ines lambs, average 28.62 kg LW were allotted to a completely randomized design and fed diets containing 20, 40, 60 e 80% of maniçoba hay.The mean intakes of DM, OM, CP and CT were 1.24, 1.12; 0.20; and 0.827 kg/d, respectively, and […]

Two experiments were carried out to evaluate the nutritional utilization of soybean hulls for growing horses. In the digestibility assay, four colts, averaging 11 months of age and 350±26kg, were used to determine the nutritional value of diets with soybean hulls. The experimental design was square latine (4 x 4). Four diets were used, one as a reference and three as test diets, where the soybean hulls replaced 33.3, 66.6 and 100% of the Tifton 85 hay of the reference […]

Two experiments were conducted with the objective of evaluating the use of high- moisture corn silage for growing horses. In the first experiment 12 male foals, 11 months old, with live weigth of 232.17±10.22 kg, were used in a digestibility trial to determine nutritional feeding value of high moisture corn silage. Two diets were used, a reference diet and one test diet, in which high- moisture corn silage replaced 25% of reference diet on dry matter basis. Total feces collection […]

The objective of this research was to study three levels of pelleted citrus pulp (PCP) in substitution to corn in diets of growing fillies. Twenty-one purebred and crossbred Arabian fillies averaging 278+9.6 kg of initial live weight and 18 months of age were used. The animals were maintained in individual pens and were daily exercised. A completely randomized design with three treatments: basal diet (T1), 7.5% PCP (T2) and 15.0% PCP (T3) with seven replicates, and with the filly as […]
