“…Some researchers (Mattoni et al, 2007;Larwence, 2000) have reported that urea supplementation increased DM and NDF contents in sorghum straw compared with the untreated straw. Silages with additives were lower than those without additives in hemicellulose and cellulose contents, and also b fraction of in situ rumen degradability for both DM and CP.…”

In situ degradability and gas production (GP) parameters of sweet sorghum and sweet sorghum bagasse silages compared with maize silage were determined in mini silos in order to compare the nutritional value of ensiled sweet sorghum and its bagasse with maize silage. Experimental treatments were 1) maize silages (MS) as control, 2) sweet sorghum silage (SS) and 3) sweet sorghum bagasse silage (BS) both supplemented with urea or molasses (10 and 50 g/kg dry matter (DM) basis, respectively). Triplicate silage samples were prepared for each treatment in laboratory silos for 90 days. The in situ degradability of DM and crude protein (CP) of fresh and 90-d ensiled forages were measured using three none lactating dairy cows fitted with rumen cannulae over 96 h. In vitro gas production was measured for 96 h and organic matter digestibility (OMD), metabolisable energy (ME) and net energy for lactation (NE l ) were estimated based on gas production parameters. Fresh sorghum and its bagasse had lower (P<0.01) ME, NEl and OMD than fresh maize. Fresh sorghum and bagasse had greater (P<0.05) immediately soluble fraction (a) of DM than fresh maize but for slowly degradable fraction (b) of DM opposite trend (P<0.01) was observed. The a fraction of CP in situ degradability of maize plant was greater than fresh sorghum and bagasse (P<0.01). Adding urea plus molasses increased (P<0.05) in situ a fraction of DM and CP and effective rumen degradability of DM and CP (P<0.01) in addition to ME and in vitro OMD for SS and BS which were rather comparable with MS. It seems that combination of urea and molasses as silage additives improves the nutritional quality of sweet sorghum and bagasse silages.

“…Cette augmentation est liée à la formation de produits (réaction de Maillard) non solubilisés, lors du dosage aux détergents neutres (Scheineider et Flachowsly, 1990). Une autre raison serait que des éléments solubles en présence d'une quantité importante d'eau soient solubilisés (Ben Salem et al, 2005a) et entraînés vers le fond lors du traitement (Larwence et al, 2000). Ce qui expliquerait l'augmentation plus importante des parois des gousses concassées.…”

Dans la zone nord soudanienne du Burkina Faso, les gousses de Piliostigma reticulatum sont intensément utilisées pendant la saison sèche comme aliment d'appoint pour le bétail. L'objectif de cette étude est d'améliorer la qualité nutritionnelle de ces gousses pour optimiser leur apport. Neuf rations comprenant chacune des gousses de P. reticulatum (70 p.100) et du foin de Pennisetum pedicellatum (30 p.100) distribuées à raison de 50 g MS/kg p 0,75 ont été testées sur des ovins de race Djallonké. Les gousses ont subi différents traitements physiques (concassage, mouture) suivis ou non de traitement à l'urée auxquelles est associé dans certains cas du charbon de bambou à des doses de 0,25 ou 0,50 g/kg PV dans le but d'influencer l'action des tanins. L'utilisation de l'urée a entraîné, quelle que soit la forme de distribution, une amélioration de la digestibilité, surtout celle des matières azotées en raison de l'augmentation significative de leur teneur. L'adjonction du charbon de bambou n'a amélioré la digestibilité des gousses non traitées à l'urée qu'à la dose de 0,50 g/kg PV. Par contre, sur des gousses traitées à l'urée, il a permis une amélioration significative (p<0,05) de la digestibilité à la dose de 0,25 g/kg PV.

Two tons of and chopped millet and sorghum straws have been treated with an urea solution at 5% (100 kg of straw, sprinkled with 50 lt. of solution). Treated straws were used as basic diet (900 g day) associated to 100 g of cotton cake for 24 growing Djallonke rams in comparison to non treated straws. Four groups of animals were fed for 98 days with: urea treated sorghum (UTSS), not treated sorghum straw (NTSS), treated millet (UTMS), non treated millet straw (NTMS). Treated straws presented an increase of NDF of about 9%, of total nitrogen from 2 to 3 times while digestibility of dry matter increased respectively by 8,8% and 23,0% respectively in treated sorghum and millet. Also dry matter intake increased by 4,5% and 15,5% for treated sorghum and millet respectively compared to non treated. Mean weekly weight gain were significantly higher (P<0.05) for UTSS e UTMS compared to NTSS e NTMS. While the weekly weight gain, did not differed between UTSS vs. UTMS and NTSS vs. NTMS. At the end of the trial the UTSS and UTMS group presented a weight gain of about 40% and 38.7%, of their initial weight; while the gain for both NTSS and NTMS was respectively of 31.1% and 29.5%
