Nutritional profiles of three genotypes of sugarcane silage associated with calcium oxide

Nutritional profiles of three genotypes of sugarcane silage associated with calcium oxide

The objective of this study was to evaluate, based on chemical composition and in vitro dry matter (DM) digestibility, silages of different sugarcane genotypes after exposure to different doses of calcium oxide (CaO) and to identify that most appropriate dose for use in ruminant feed. The experiment...

Zusammenfassung:The objective of this study was to evaluate, based on chemical composition and in vitro dry matter (DM) digestibility, silages of different sugarcane genotypes after exposure to different doses of calcium oxide (CaO) and to identify that most appropriate dose for use in ruminant feed. The experiment was conducted using a completely randomized 3 × 4 factorial arrangement with three sugarcane genotypes (‘IAC‐862480’, ‘SP‐791011’ and ‘CTC‐3’) and four levels of the additive CaO (0, 15, 30 and 45 g kg−1). A quadratic effect was observed (P  0.05) of genotype or an interaction effect between genotype and CaO level on crude protein content in the silages. There was an interaction effect (P
