The Effect of Substitution of Dry Bamboo Leaves at Different Proportions with Concentrate Mix on Feed Intake, Digestibility and Live Weight Gain of Local Sheep Fed Tef Straw (Published)
A feeding and digestibility trials were conducted at Assosa ATVET college, Benishangul-Gumuz Region, Ethiopia, using twenty five yearling local sheep weighing on average 18.7 + 2.12 (mean + SD) kg, to investigate the effect of substituting dry bamboo leaves in a concentrate mix on feed intake, digestibility and body weight (BW) gain of sheep. A randomized complete block design with five treatments and five replications was used to conduct the experiment. The treatments included feeding a basal diet of tef straw alone (T1, control), and supplementation with dry bamboo leaves at 100% (T2), 67% bamboo leaves hay and 33% concentrate mixture (T3), 67% concentrate mixture and 33% bamboo leaves hay (T4)and100% concentrate mixture (T5).The supplements were given at 300g DM/head/day The concentrate mixture consisted of wheat bran (WB) and noug seed cake (NSC) at the ratio of (2:1). The animals were housed in individual pens and daily offered tef straw, allowing 35% refusal. Water and salt block comprising of sodium chloride were available free choice. The results indicated that there were higher (P<0.001) total DM intake in the supplemented (775.2-798.5 g/head/day) than the control (502 g/head/day) treatment. The group that consumed tef straw alone and those supplemented with 67:33 concentrate to bamboo mix (T4) consumed more (P<0.001) basal diet than the other treatments Sheep supplemented with the dry bamboo leaves and concentrate mix at different proportions had higher (P < 0.001) CP intake than the control ones. The CP intake was 40.9, 100.9, 96.2, 93.9 and 88.5 g for T1, T2, T3, T4 and T5, respectively. Similarly, there was higher (P<0.001) daily BW gain in the supplemented sheep (14.4-36g/head/day) than in the control (-37g/ head /day) ones. The digestibility of CP (P<0.001) DM and OM (P<0.001) were higher in the supplemented than in the control treatment.
Review of Bamboo Value Chain in Ethiopia (Published)
Ethiopia has greatest bamboo resources in Africa representing a significant proportion of Africa’s total bamboo resources. The main objective of this review to increase the understanding of problems and constraints facing bamboo production and marketing system, current opportunities and challenges of bamboo marketing, economic, environmental and aesthetic value of bamboo in Ethiopia. Bamboo value chain includes wide range of production to consumption systems and actors. Depending on which market is served, the bamboo products in Ethiopia passes through various intermediary stages until it reaches the final customers. But their value chain linkage is undeveloped. Bamboo agribusiness has worldwide opportunities. Bamboo products currently have very huge demand. It can be utilized at all levels of industrial activity from small craft based industries to modern highly integrated plants. Imbalance between demand and supply is one the core challenges to bamboo agribusiness sector in Ethiopia. Bamboo has huge economic, environmental, aesthetic/cultural values. It is applicable in a variety of engineering fields including landscape, civil and chemical engineering. Bamboo has also culture value in addition to economic and ecological value in Ethiopia. For example Dawuro in Ethiopia; the longest woodwind musical instrument in the world locally called “Dinka” (4 to 5 meters long, four in number) which is made from bamboo and other materials. Therefore; bamboo has worldwide uses ranges from medicine to nutrition (has 1500 uses). It is possible to exploit the existing opportunities of bamboo sub-sector through value chain approach by promoting the formation of farmers’ associations, provision of appropriate technology and training for pre-processing, facilitating capacity development with technology transfer and upgrading skills in bamboo processing and creation of a network and links with other associations, stakeholders and partners are important to solve challenges of bamboo industry in Ethiopia.
