Inclusão de glicerina bruta e glucose industrial na dieta de caprinos Saanen em cre scimento

Abstract

We evaluated the percentage inclusion of crude glycerin (0, 1.75, 3.50 and 5.25) and industrial glucose (0, 1.25, 2.50, 3.75) in the reconstituted substitute, in the goat diet intake and digestibility, in the development of the rumen tissue, on performance and biometric measurements. They were used 30 Saanen goats, not castrated, with an average weight of 14.36 ± 2.85 kg, in a randomized design. The digestibility coefficients were obtained by total collection of feces. The inclusion of industrial glucose influenced linearly the intake of dry matter (DM), organic matter (OM), crude protein (CP), gross energy (GE) and water. Glycerin influenced linearly only crude protein intake (CP), gross energy (GE) and water. The digestibility of acid detergent fiber rose with increasing glucose levels while protein digestibility. The glucose induced reduction in consumption linearly, while glycerin levels did not affect the studied parameters. The inclusion levels studied, both as glucose to glycerol did not affect the development of the rumen tissue, independent of the local portion collected. The biometric measurements showed a linear response for both energy foods tested, with higher values for glucose to 2.50% of inclusion, and old growth between 1-14 days and 42-56 days. The inclusion of glucose to 2.50% proved to be the best processing performance of animals.
