Abstract

The objective of this study was to evaluate the in situ dry matter degradability of fruit flour of guacima, Guazuma ulmifolia check for this species in other resources Lam, with different flour fruits of three legumes: tepame Acacia pennatula check for this species in other resources , cascalote Caesalpinia coriaria check for this species in other resources , and vainillo Senna atomaria check for this species in other resources and a Rhamnaceae, asmol Zizyphus mexicana check for this species in other resources . Crude protein (CP), dry matter (DM) and neutral detergent fiber (NDF) were determined on each species. To evaluate in situ degradability, a Holstein cow of approximately 600 kg was used, fitted with permanent rumen cannulae with incubation times of 0, 4, 8, 12, 24, 36, 48, and 72 h, in a completely randomized design, with a split plot design, and mean comparison done by Tukey’s test (P<0.05). Results indicated dry matter content range of 49.2% for A. pennatula to 89.9% for Z. mexicana. CP content varied from 6.03 to 11.93% for C. coriaria and S. atomaria, respectively. For NDF, values were from 41.1 to 54.9% for A. pennatula and Z. mexicana, respectively. In ruminal degradation, the lowest value was presented when the fruit on the diet was the same specie G. ulmifolia with 40.1%. However, positive effects were observed with the other diets, presenting the highest value when C. coriaria of 50.4% was offered. It is concluded that the fruits showed low protein contents, including the legumes, and that in situ dry matter degradability of guacima had a positive effect among the evaluated species.

 es Degradabilidad In Situ de la Materia Seca de la Harina Del Fruto de Guacima, Guazuma ulmifolia check for this species in other resources , Con Dietas de Frutos de Especies Arbóreas

Resumen

El objetivo de este estudio fue evaluar la degradabilidad in situ de la materia seca de la harina del fruto de la guácima, Guazuma ulmifolia check for this species in other resources Lam., con dietas de harina de frutos de tres leguminosas: tepame Acacia pennatula check for this species in other resources , cascalote Caesalpinia coriaria check for this species in other resources y vainillo Senna atomaria check for this species in other resources y una Rhamnaceae, asmol Zizyphus mexicana check for this species in other resources . Se determinó la proteína cruda (PC), materia seca (MS) y fibra detergente neutro (FDN) de las cinco especies. Para la evaluación in situ se utilizó una vaca Holstein de aproximadamente 600 kg, fistulada en rumen, con tiempos de incubación de 0, 4, 8, 12, 24, 36, 48 y 72 h, en un diseño completamente al azar con arreglo de parcelas divididas y comparación de medias con la prueba de Tukey (P<0,05). Los resultados indicaron contenidos de MS desde 49,2 para A. pennatula hasta 89,9% para Z. mexicana. La PC varió de 6,03 hasta 11,99% para C. coriaria y S. atomaria, respectivamente. Para FDN, los valores fueron desde 41,1 hasta 54,9% para A. pennatula y Z. mexicana, respectivamente. En la degradación ruminal el valor más bajo se presentó cuando se le proporcionó el fruto de G. ulmifolia con 40,1%. Sin embargo, se observaron efectos positivos con las otras dietas, presentando el valor más alto cuando se le ofertó C. coriaria de 50,4%. Se concluye que los frutos presentaron bajos contenidos de proteína, incluyendo las leguminosas y que la degradabilidad in situ de la MS de la guacima tuvo un efecto positivo entre las especies evaluadas.
