The objective of this study was to evaluate nutrient intake, blood parameters and digestibility of nutrients on 20 feedlot Saanen goats (70.65±7.39 kg) at 21 days prepartum. Diets with the following energy levels and forage:concentrate ratios were fed: 2.95, 2.83, 2.70, 2.58, and 2.44 Mcal of ME/kg of DM and 40:60, 50:50, 60:40, 70:30, and 80:20, respectively. A completely randomized design with four replications per treatment was used. Animal body weight and blood samples were taken weekly. The different dietary […]

The objective of this study was to evaluate production, blood metabolites, and nutrient digestibility of Saanen goats either in the beginning or after 60 days of lactation. Twenty goats averaging 59.59 ± 6.97 kg of body weight were assigned to a completely randomized design. The following forage:concentrate ratios were used: 40:60, 50:50, 60:40, 70:30, or 80:20 and provided 2.95, 2.83, 2.70, 2.58, or 2.46 Mcal ME/kg DM, respectively. Animals were confined in individual stalls with daily measurements of feed intake […]
