Eficiência de seleção de dietas contendo fontes de óleo para ovinos

Abstract

Lipids in ruminant diets allow for high energy consumption and should be used with caution and at strategic times. The most different sources of optimization used to replace more energy energy from grains and increase the food efficiency of diets and improve efficiency. The objective of this study was to evaluate the ingestive behavior, selection index and residual food consumption and of confined sheep fed diets containing 2% of any of the following oils: soybean, sunflower and residual frying. Two lambs, non-castrated breed 1, were used (45.00 ± 8 kg of body weight, 9 ± 0.5 months of age), distributed in a triple 4x4 Latin square experimental design. The animals, started for 10 days of adaptation to start the experiment, each period lasted 20 days of adaptation and 5 days of adaptation. The animals were housed in metabolic cages and individual drinking troughs. The animals received diets containing a 2% inclusion in the DM of one of the different sources of oil: sunflower; and residual soybeans from frying and an additional treatment without oil addition (control). Animals were evaluated for English behavior and NDF selection index. The selection of medium particles (8mm and very short (<1.18mm) showed a significant difference with soybean oil being more used for treatment by the animals. The neutral detergent fiber selection index (%) was lower in the control treatment and a significant difference (P<0.005) for the other treatments for short fibers (<8, >1.18 mm). The negatives of CAR indicate that the animals are more efficient in soybean, all treatments with frying oil. There was no significant difference (P<0.05) regarding the ingestive behavior in any of the treatments.See it as an interesting alternative for the feeding of wines that is not attractive and attractive for the nutrition of rum.
