Item Evaluación de un alimento desarrollado por Fermentación en Estado Sólido (FES), sobre la respuesta productiva de vacas holstein en pastoreo, suplementadas con diferentes niveles de inclusión de FES-papa(Universidad Pedagógica y Tecnológica de Colombia, 2016) Alfonso Barbosa, Laurint; García Daza, Iván Merardo; Borrás Sandoval, Luis MiguelThe potato is one of the main monocultures of Boyacá, and about 30% of production is not suitable for marketing and has long been used in animal feed directly. This work shows the evaluation of a food technology developed under solid state fermentation FES-papa, and productive response compared with a commercial concentrate widely used in animal husbandry in the region. The study was conducted on the farm the valley; Finca San Jose, the Poravita village in the municipality of Oicata. 3 cows age and stage similar lactation were taken, which were supplemented with three diets and control diet or treatment 1 T1 = 6 g / kg bw concentrate, treatment 2, T2 = 6 g / kg bw food FES-papa, treatment 3 T3 = 9 g / kg pv food; production parameters were evaluated daily milk production kg / day, milk composition and daily weight gain; resulting in the FES-papa food behaved similarly to commercial feed way, except for the daily weight gain where T3 achievement daily gain of more than 1000 g / day; on the other serological parameters as glucose, total protein, cholesterol, ketones and pH were evaluated, without encountering major differences between the different treatments. Keywords: Feeding, daily milk production, daily gain, milk composition, serological parameters, glucose, ketones, pH, cholesterol, total protein, cholesterol, ketones and pH were evaluated, without encountering major differences between the different treatments.
