Partial replacement of corn grain with levels of crude glycerin on feed intake, digestibility, ruminal fermentation, nitrogen utilization, and performance of feedlot lambs

This study aimed to evaluate the effects of replacing corn grain with increasing levels (0, 50, 100, 200 g kg −1 of dry matter) of crude glycerin (GLY) on feed intake, digestibility, ruminal fermentation, nitrogen utilization, blood glucose and performance of male lambs fed a high-concentrate diet....

Description
Summary:This study aimed to evaluate the effects of replacing corn grain with increasing levels (0, 50, 100, 200 g kg −1 of dry matter) of crude glycerin (GLY) on feed intake, digestibility, ruminal fermentation, nitrogen utilization, blood glucose and performance of male lambs fed a high-concentrate diet. Five castrated adult rumen-cannulated male lambs (30.3 ± 3.12 body weight) were used in a 5 × 5 Latin square design to evaluate metabolism parameters. Forty lambs (22.3 ± 3.8 kg body weight) were used in a randomized block design for performance evaluation. Diets contained 25 g kg −1 sugarcane bagasse ( Saccharum officinarum L.) and 75 g kg −1 concentrate. There was a quadratic effect ( P  = 0.03) of GLY on the intakes of DM and neutral detergent fiber ( P  = 0.01). Increasing GLY levels did not affect ( P  > 0.05) nutrient digestibility and decreased linearly ( P
