Effects of supplementation frequency on nutritional performance and metabolism of cattle fed low-quality tropical forage

Our objective was to evaluate the nutritional performance and metabolism of cattle fed low-quality tropical grass forage and supplemented at different frequencies. Five rumen and abomasum fistulated Nellore heifers (386 kg body weight) were used in a 5 × 5 Latin square design. The five treatments we...

Description
Summary:Our objective was to evaluate the nutritional performance and metabolism of cattle fed low-quality tropical grass forage and supplemented at different frequencies. Five rumen and abomasum fistulated Nellore heifers (386 kg body weight) were used in a 5 × 5 Latin square design. The five treatments were: control (without supplementation) and supplementation every 12, 24, 48, and 96 h. The amount of supplement provided was equivalent to 2.5 g/kg of body weight in a daily basis. Overall, supplementation had a positive effect (P
