Abstract
With the objective of evaluating the voluntary consumption, the ruminal behavior, measured as pH and ammoniac nitrogen (NNH3), and the digestibility in-vivo of the 10% urea ammonified African palm fiber (FPAU), this study was conducted in the Universidad de Ciencias Aplicadas y Ambientales UDCA located in Bogota at 2,600 m sea level. Six whole male ovine with live weight between 27 - 35 were allocated in individual metabolic cages and subjected to three treatments: 1) Control 0% FPAU + 100% pangola Digitaria decumbens hay (Hpa); 2) 50% FPAU +50% Hpa; 3) 100% FPAU + 0% Hpa. A latin square design was used, where all the ovine received the three diets and variation analysis and Duncan test were applied. The consumption of dry matter (MS) in g/Kg PV0.75 did not show significant differences (P > 0.05). The pH increased when the FPAU level was increased, being significantly higher (P < 0.05) on treatment 3, in comparison with the other two treatments. The NNH3 level in rumen was significant ( P < 0.05) with values in mg/100 ml of 22.5, 40.9 and 75.2 for treatments 1, 2, and 3 respectively. The digestibility of the MS and the cellular wall did not show significant differences (P > 0.05). The total nitrogen digestibility was superior and significant ( P < 0.05) for treatments 1 and 3 in comparison with the control. The ruminales parameters as well as the digestibility and consumption of MS values suggest that the use of FPAU is a feasible alternative for ruminant species feeding. Con el objetivo de evaluar el consumo voluntario, el comportamiento ruminal, medido como pH y Nitrógeno amoniacal (NNH3) y la digestibilidad in vivo de la fibra de palma de aceite amonificada con urea al 10% (FPAU), se realizó un estudio en la Universidad de Ciencias Aplicadas y Ambientales UDCA, localizada en Bogotá a 2.600 msnm. Seis ovinos machos enteros, canutados, con peso vivo entre 27-35 kg fueron alojados en jaulas metabólicas individuales y sometidos a tres tratamientos: 1) Control: 0% FPAU + 100% heno de pangola (Digitaria decumbens Stent.) (Hpa); 2), 50% FPAU + 50% Hpa; 3), 100% FPAU + 0% Hpa. Se utilizó un diseño de cuadrado latino, en el cual todos los ovinos recibieron las tres dietas y se realizó el análisis de varianza y prueba de Duncan. Los consumos de materia seca (MS) en g/kg PV0.75 no presentaron diferencias significativas (P > 0,05). El pH aumento al incrementar el nivel de FPAU, siendo significativamente mayor (P < 0,05) en el tratamiento III (6,9) en comparación con los otros dos tratamientos. El nivel de NNH3 en rumen fue significativo (P < 0,05) con valores de 22,5, 40,9 y 75,2 mg/100 ml para los tratamientos I, II y III respectivamente. La digestibilidades de la MS y la pared celular no presentaron diferencias significativas (P > 0,05). La digestibilidad del nitrógeno total fue superior y significativa (P < 0,05) para los tratamientos II y III en comparación con el control. Los parámetros ruminales, los valores de digestibilidad y de consumo de MS sugieren que el uso de FPAU se constituye en una alternativa viable de alimentación para las especies rumiantes.
