ABSTRACT We evaluated the effects of adding fungal inoculants composed of Rhodotorula mucilaginosa and Trichoderma longibrachiatum to rehydrated corn silage fed to lambs receiving a tropical grass hay-based diet and their impact on financial viability. The effects of combined inoculation on dry matter intake (DMI) and weight gain were analyzed. A total of 22 male Dorper × Santa Ines crossbred lambs, with an average body weight of 14.20 ± 1.74 kg, were randomly assigned to two treatments: (1) control (CTL), […]

Eighty six young bulls were used, divided into four genetic groups: Nellore (n=20), Canchim (n=17), ½ Canchim ×Nellore (NC) (n=25) and ¾ Canchim ×Nellore (TQ) (n=24). The animals were weighed every 28 days to evaluate the average daily gain (kg/day), dry matter intake (kg/day) and feed conversion. When the animals reached slaughter weight (450 kg) and fat thickness greater than 4 mm, were slaughtered to evaluate the rib eye area (cm2), subcutaneous fat thickness (mm), marbling, shear force, ether extract […]

Three experiments were carried out to evaluate the performance and nutritional value of the extruded corn for broilers from one to 21 days of age. In the first experiment, the metabolism of pre-gelatinized corn, corn starch and corn germ meal was assessed by the total excreta collection method from 4 to 7 days of age and values of apparent (AME) and corrected metabolizable energy (CAME) and the results were, respectively: 3370, 3379.7, 3259.1 kcal/kg de AME and 3299.8, 3369.7, 3051.6 […]
