Ruminal Degradability of Tropical Feeds and Their Potential Use in Ruminant Diets

Abstract

L'objectif de cette étude était de déterminer la dégradabilité des copeaux de manioc (CC), des déchets de manioc (CW), de la patate douce jaune (YP), de la patate douce blanche (WP), de la patate douce violette (PP), de la farine de maïs (CM) et du son de riz (RB) en utilisant une technique in situ. Deux bouvillons à fistules ruminales d'un poids moyen de 303±10 kg ont été utilisés pour déterminer les dégradabilités in situ du DM et de l'OM. Sept sources d'alimentation ont été pondérées dans des sacs en nylon (taille de pores de 38 µm) et incubées en ruminant pendant 1, 2, 4, 6, 8, 12, 24 et 48 h. Les résultats ont montré qu'asymptote (a+b) et la dégradabilité effective (DE) du MS des sources d'énergie classées de la plus élevée à la plus basse ; CC, YP, WP, PP, RB, CW et CM (99,3, 92,5 ; 97,6, 87,9 ; 97,5, 87,9 ; 97,2, 87,8 ; 87,5, 63,6 ; 78,6, 63,0 et 81,7 ; 59,3, respectivement) et pour l'asymptote OM (a +b) et la dégradabilité effective (DE) étaient similaires à celles de la dégradation du MS (99,4,93,4 ; 98,8, 89,8 ; 98,5, 89,4 ; 98,4, 88,1 ; 92,4,65,8 ; 85,1, 66,9 et 83,6, 63,3, respectivement). que la caractéristique de disparition de la CC était la plus élevée et qu'elle peut potentiellement faciliter la réalisation d'une disponibilité optimale d'énergie ruminale : protéine en particulier avec la NPN pour la synthèse protéique microbienne.(

El objetivo de este estudio fue determinar la degradabilidad del chip de yuca (CC), los desechos de yuca (CW), la batata amarilla (YP), la batata blanca (WP), la batata morada (PP), la harina de maíz (CM) y el salvado de arroz (RB) utilizando la técnica in situ. Se utilizaron dos novillos fistulados rumianalmente con un peso promedio de 303±10 kg para determinar las degradabilidades in situ de DM y OM. Siete fuentes de alimento se pesaron en bolsas de nylon (tamaño de poro de 38 µm) y se incubaron rumianalmente durante 1, 2, 4, 6, 8, 12, 24 y 48 h. Los resultados mostraron que la asíntota (a +b) y la degradabilidad efectiva (ED) de la DM de las fuentes de energía clasificadas de mayor a menor; CC, YP, WP, PP, RB, CW y CM (99.3, 92.5; 97.6, 87.9; 97.5, 87.9; 97.2, 87.8; 87.5, 63.6; 78.6, 63.0 y 81.7; 59.3, respectivamente) y para la asíntota OM (a +b) y la degradabilidad efectiva (ED) fueron similares a las de la degradación de la DM (99.4,93.4; 98.8, 89.8; 98.5, 89.4; 98.4, 88.1; 92.4,65.8; 85.1, 66.9 y 83.6, 63.3, respectivamente). que la característica de desaparición del CC fue la más alta y potencialmente puede facilitar el logro de una disponibilidad ruminal óptima de energía: proteína especialmente con NPN para la síntesis de proteínas microbianas.(

The objective of this study was to determine the degradability of cassava chip (CC), cassava waste (CW), yellow sweet potato (YP), white sweet potato (WP), purple sweet potato (PP), corn meal (CM), and rice bran (RB) using in situ technique.Two ruminally fistulated steers with an average weight of 303±10 kg were used to determine in situ degradabilities of DM and OM.Seven feed sources were weighted in nylon bags (38 µm pore size) and incubated ruminally for 1, 2, 4, 6, 8, 12, 24, and 48 h.The results showed that asymptote (a+b) and effective degradability (ED) of DM of energy sources ranked from the highest to the lowest; CC, YP, WP, PP, RB, CW, and CM (99.3, 92.5; 97.6, 87.9; 97.5, 87.9; 97.2, 87.8; 87.5, 63.6; 78.6, 63.0 and 81.7; 59.3, respectively) and for OM asymptote (a+b) and effective degradability (ED) were similar to those of degradation of DM (99.4,93.4; 98.8, 89.8; 98.5, 89.4; 98.4, 88.1; 92.4,65.8; 85.1, 66.9 and 83.6, 63.3, respectively).It was concluded that disappearance characteristic of CC was the highest and it may potentially facilitate the achievement of optimal ruminal availability of energy: protein especially with NPN for microbial protein synthesis.(

كان الهدف من هذه الدراسة هو تحديد قابلية تحلل رقائق الكسافا (CC)، ونفايات الكسافا (CW)، والبطاطا الحلوة الصفراء (YP)، والبطاطا الحلوة البيضاء (WP)، والبطاطا الحلوة الأرجوانية (PP)، ووجبة الذرة (CM)، ونخالة الأرز (RB) باستخدام تقنية الموقع. تم استخدام توجيهين مجترعين بمتوسط وزن 303±10 كجم لتحديد قابلية تحلل DM و OM في الموقع. تم ترجيح سبعة مصادر تغذية في أكياس نايلون (حجم مسام 38 ميكرومتر) وحضنت بشكل مجتر لمدة 1 و 2 و 4 و 6 و 8 و 12 و 24 و 48 ساعة. أظهرت النتائج أن الخط المقارب (أ+ب) والتحلل الفعال (ED) من DM لمصادر الطاقة المصنفة من الأعلى إلى الأدنى ؛ CC، YP، WP، PP، RB، CW، و CM (99.3، 92.5 ؛ 97.6، 87.9 ؛ 97.5، 87.9 ؛ 97.2، 87.8 ؛ 87.5، 63.6 ؛ 78.6، 63.0 و 81.7 ؛ 59.3، على التوالي) وبالنسبة لخط التقارب OM (أ+ب) والتحلل الفعال (ED) كانت مماثلة لتلك الخاصة بتحلل DM (99.4،93.4 ؛ 98.8، 89.8 ؛ 98.5، 89.4 ؛ 98.4، 88.1 ؛ 92.4،65.8 ؛ 85.1، 66.9 و 83.6، 63.3، على التوالي). أن خاصية اختفاء CC كانت الأعلى وقد تسهل تحقيق التوافر الأمثل للطاقة: البروتين خاصة مع NPN لتخليق البروتين الميكروبي.(
