DETERMINATION OF FECAL DIGESTIBILITY OF DIETS FOR GROWING PIGS WITH THE SUBSTITUTION OF SOY FLOUR BY PROTILEN ω3 | DETERMINACIN DE LA DIGESTIBILIDAD FECAL DE DIETAS PARA CERDOS EN CRECIMIENTO CON LA SUSTITUCIN DE LA HARINA DE SOYA POR PROTILEN ω3

الأسبانية؛ قشتالية. Con el objetivo de evaluar la utilizacin digestiva del uso del concentrado proteico Protilen ω3 en dietas para cerdos en crecimiento se realiz este estudio. Se determin la digestibilidad fecal y el balance de nitrgeno. Para ello, se utilizaron 8 cerdos machos castrados de cruce comercial de 13 kg de peso corporal promedio. Los cerdos fueron distribuidos segn un diseo de doble cuadrado latino 3x3 en tres tratamientos. Los tratamientos consistieron en dietas de harinas de maz y soya, con o sin la sustitucin de la fuente proteica en un 0 (Tto control), 33% (Tto I) y 66% (Tto II) por Protilen ω3. La composicin de las dietas cumpli con los requerimientos y se consider apta sanitariamente para consumo animal. En relacin a los ndices digestivos digestibilidad se obtuvieron valores elevados para animales de esta categora, aunque no existieron diferencias significativas (p0.05) entre el concentrado con la sustitucin o no de la harina de soya por Protilen ω3. Se concluy que el concentrado proteico Protilen ω3 posee alta digestibilidad y se puede sustituir la protena de la harina de soya en la dieta sin que se afecten los ndices digestivos.

إنجليزي. In order to evaluate the digestive utilization of the use of Protilen ω3 protein concentrate in diets for growing pigs, this study was carried out. Fecal digestibility and nitrogen balance were determined. For this, 8 commercial castrated male pigs of 13 kg of average body weight were used. The pigs were distributed according to a Latin 3x3 double square design in three treatments. The treatments consisted of diets of corn flour and soybeans, with or without the replacement of the protein source by 0 (control Tto), 33% (Tto I) and 66% (Tto II) by Protilen ω3. The composition of the diets met the requirements and was considered sanitary for animal consumption. Regarding digestive indices, digestibility, high values were obtained for animals in this category, although there were no significant differences (p 0.05) between the concentrate with the replacement or not of soy flour by Protilen ω3. It was concluded that the protein concentrate Protilen ω3 has high digestibility and it is possible to substitute the protein of soybean meal in the diet without affecting the digestive indices
