Palatability and digestibility of horse diets containing increasing levels of citrus pulp
Journal Title: Revista MVZ Cordoba - Year 2015, Vol 20, Issue 2
Abstract
Objective. To evaluate the impact of citrus pulp on the palatability and digestibility of horse diets and the physicochemical characteristics of the feces. Materials and methods. The diets were composed of 60% of the energy from the forage and 40% from the concentrate, with increasing levels of citrus pulp. Two different tests were performed. The first test assessed the palatability of concentrates. Using a randomized experimental design, 15 horses were observed for 10 days. The variables recorded were first action, first choice and intake ratio (IR). Five horses were arranged in 5x5 Latin Square design for the test assessing digestibility and fecal physicochemical characteristics. The apparent digestibility of the nutrients and the color, consistency, pH and buffering capacity (BC) of the feces were evaluated. Results. The addition of increasing levels of citrus pulp had an effect (p≤0.001) on first action. A difference was also observed in first choice, and the addition of 0, 7 or 14% of citrus pulp was preferred. A difference between treatments (p≤0.001) was also observed for IR, and the control concentrate was consumed the most. The amount of citrus pulp included had no effect (p>0.05) on the digestibility of nutrients, fecal consistency and color, and there was no effect (p>0.05) on fecal pH and BC. Conclusions. Horses can identify the presence of citrus pulp in concentrates but prefer concentrates without added citrus pulp. Citrus pulp does not negatively affect the digestibility of concentrates or the physicochemical characteristics of the feces; thus, citrus pulp is a viable alternative ingredient in the formulation of horse diets.
