“…Pendant les dernières décennies, la méthode du gaz-test a été largement utilisée pour évaluer les interactions digestives entre les constituants de la ration (Davies et al, 2000 ;Makkar, 2005 ;Tendonkeng et al, 2018 ;Sun et al, 2020). L'objectif de cette étude était d'évaluer l'effet de la substitution du tourteau de coton Ba Mariama par les gousses de Piliostigma reticulatum sur la fermentation in vitro et l'ingestion de la paille de riz avec ou sans mélasse-urée chez des taurillons.…”

L’effet associatif entre les constituants d’une ration peut induire un effet positif ou negative sur les performances de production des ruminants,en function de la nature des constituants de la ration. De plus, La prediction de la valeur alimentaire de la ration sur la base de la somme des valeurs des constituants comporte beaucoup de limites. Deux essais ont été conduits pour évaluer l’effet associatif entre du tourteau de graine de coton non décortiquée (TBM) et les gousses de Piliostigma reticulatum (GP) sur l’ingestion volontaire (essai 1) et la fermentation in vitro à l’aide de la technique du gaz test (essai 2) de la paille de riz seule (PS) ou avec la mélasse et l’urée (PMU). Le TBM a été ajouté à PS ou à PMU dans la proportion: 70 / 30 (PS/TBM ou PMU / TBM). Les GP ont été ensuite substituées au TBM dans la proportion de 15%. Quatre rations ont été formulées pour l’essai 1: R1 (70% PS + 30% TBM), R2 (70% PMU + 30% TBM), R3 (70% PMU + 15% TBM + 15% GP) et R4 = R3 mais TBM et GP ont été distribués de façon séquentielle. Deux autres rations: 100% PS et 100% PMU en plus des rations précédentes, ont servi de substrats pour le gaz test. La ration R2 comparée à R1 a significativement (p < 0.05) amélioré les performances de croissance des taurillons. Par contre, l’apport de GP n’a pas eu d’effet car les GP n’ont pas été consommées tout au long de l’essai. Contrairement aux traitements PS et TBM (essai 2), les traitements PMU et TBM ont engendré une augmentation significative (p < 0.05) du taux horaire (c) de fermentation de la fraction insoluble (b), la concentration des acides gras volatiles (AGV) et la production de gaz à 12, 24, 36 et 48 h. L’interaction entre PMU, TBM et GP a été positive et significative. L’apport de la mélasse-urée en plus du tourteau et les gousses de Piliostigma a permis d’améliorer la valeur nutritive de la paille de riz. The associative effect between the constituents of a ration can positively or negatively affect ruminant animals ‘performances, depending on the nature of the constituents of the ration. Moreover, predicting the feeding value of the ration by simply adding the individual feed value of the constituents has some limitations. Two trials were conducted to assess the associative effect between unhulled cottonseed meal (TBM) and Piliostigma reticulatum pods (GP) on voluntary intake (trial 1) and in vitro fermentation using the gas production technique (trial 2) of rice straw alone (PS) or PS with molasses and urea (PMU). TBM was added to PS or PMU in the proportion: 70/30 (PS/TBM or PMU/TBM). The GPs were then substituted for the TBM in the proportion of 15%. Four rations were formulated for trial 1: R1 (70% PS + 30% TBM), R2 (70% PMU + 30% TBM), R3 (70% PMU + 15% TBM + 15% GP) and R4 = R3 but TBM and GP distributed sequentially. Two other rations: 100% PS and 100% PMU in addition to the previous rations, served as substrates for the gas test. The R2 ration compared to R1 significantly (p < 0.05) improved the growth performance of the young bulls. On the other hand, the supply of GP had no effect because the GP were not consumed throughout the trial. Unlike the PS and TBM treatments (trial 2), the PMU and TBM treatments generated a significant increase (p < 0.05) in the hourly rate (c) of fermentation of the insoluble fraction (b), the concentration of volatile fatty acids (VFAs) and gas production at 12, 24, 36 and 48 h. The interaction between PMU, TBM and GP was positive and significant. The supply of molasses and urea in addition to cottonseed cake and Piliostigma pods improved the nutritional value of rice straw.

“…Small ruminants in sub-Saharan Africa depend on natural pasture and crop residues for the long dry season. These areas are faced with seasonal dry periods in which the quality and availability of the pastures decreases leading to an imbalance of essential nutrients resulting in low feed intake and poor performance (Pamo et al, 2007;Tendonkeng et al, 2016;Tendonkeng et al, 2018). Cereals in general, and especially rice, are not only the staple food for people in sub-Saharan Africa (Sohl, 2005), but they also produce large quantities of crop residues that are abandoned or burnt in the fields (Yaningzhang et al, 2012).…”

“…Rational exploitation of these crop residues can be a promising way to overcome the quantitative and qualitative forage deficit especially during the long dry periods.Although, it is low in quality and feeding it alone does not provide enough nutrients to the small ruminants to maintain high production levels. The high level of lignifications and limited ruminal degradation of the carbohydrates and the low content of nitrogen are the main deficiencies of the rice straw affecting its value as feed for ruminants (Tendonkeng et al, 2016;Tendonkeng et al, 2018).…”

The evaluation of the effect of molasses level on the ingestion and in vivo digestibility of rice straw treated with 5% urea was carried out at the University of Dschang. The rations were distributed in a completely Randomized design comprising three groups of three West African dwarf goats ages about 12 months with a comparable average weight. These animals were housed individually in the digestibility cages. The adaptation and data collection periods were 8 and 6 days respectively. Each goat received 800 g of rice straw treated with 5% urea per day with inclusion of 0% molasses (RS5 + M0) for group 1; 5% molasses (RS5 + M5) for group 2 and 10% molasses for group 3 (RS5 + M10). A sample of 100 g of each ration, feces and 10 ml of urine was collected every morning for chemical analysis and digestibility assessment. The results of this study show that the addition of molasses enhances the digestibility of the organic matter and the digestible crud protein of the rice straw treated with 5% urea. DM, OM and NDF intake of the RS5 + M0 ration (375, 343.8 and 298 g/d) was higher than that of RS5 + M5 (322.9, 295, 3 and 246.1 g/d) and RS5 + M10 (344.5, 314.8 and 256.6 g/d). The highest apparent dry matter (55.8%), organic matter (58.4%) and NDF (65.2%) digestibility were obtained with RS5 + M5 ration. The apparent nitrogen digestibility of the RS5 + M5 ration was significantly higher (P˂0.05) than that of the RS5 + M0 ration and comparable to that of the RS5 + M10 ration. These results show that the inclusion of molasses in rice straw treated with 5% urea does not significantly affect the ingestion and digestibility of DM, OM and NDF, but significantly improves digestibility of nitrogen.
