Abstract

In vitro gas production technique was used to predict the nutritive values of Brachiaria decumbens, Moringa oleifera, Tephrosia candida and Cajanus cajan as well as to compare the supplementation effects of the selected tropical browses on Brachiaria decumbens at ratio 60:40. Evaluation parameters were proximate composition, gas production volumes, Gas production constants, predicted metabolizable energy (ME), organic matter digestibility (OMD) and short chain fatty acid (SCFA) production. Significant (P<0.05) differences existed in all the parameters evaluated. Crude protein was highest in sole Tephrosia candida (21.44 %) and least in sole Brachiaria decumbens (13.55 %). Ether extract ranged from 3.50 % in sole Cajanus cajan to 4.50 % in Brachiaria decumbens combined with Moringa oliefera. The highest (32.43 %) crude fibre was obtained from Brachiaria decumbens in combination with Moringa oleifera and least (24.96 %) value was from sole Brachiaria decumbens. Ash content was between 14.38 % (sole Moringa oleifera) and 16.50 % in Brachiaria decumbens combined with Moringa oleifera and sole Brachiaria decumbens. Gas production from Moringa oleifera was significantly (P<0.05) highest from the beginning to the end compared to any of the experimental browses or their combination with Brachiaria decumbens. In vitro gas production characteristics also varied significantly (P<0.05) across the treatments. The potential gas production (a+b) ranged from 15.00 (Brachiaria decumbens combined with Cajanus cajan) to 21.67 ml/200mgDM (Moringa oleifera). Significant (P<0.05) differences were observed in ME, OMD and SCFA among treatments. Sole Cajanus cajan and Moringa oleifera had lower values than their combination with Brachiaria decumbens. However, sole Tephrosia candida had significantly (P<0.05) higher value of ME, OMD and SCFA than its combination with Brachiaria decumbens. It was concluded that combining Brachiaria decumbens with the selected browses improved the nutrient composition and availability.
