Review on Feed Resources with More Emphasis on Use of Cassava and Sweet Potato Meal in Chicken Diet: Ethiopia

Abstract

This review paper is aimed to focus on feed resources with more emphasis on use of cassava and sweet potato meal in Chicken diet in Ethiopia. Poultry production has significant socioeconomic roles in developing countries like Ethiopia. Households keep chickens for home consumption, selling and breeding purposes and other purposes such as social and cultural purposes. The chicken farming in Ethiopia is predominantly backyard type of farming system and it is generally disadvantaged since the poor management. According to different research results, the commonly available sources of feeds for chickens includes cereal crops and their aftermaths and household waste products or left overs. Roots and tuber crops can be incorporated in different substitution levels in chickens' diet. Sweet potato and cassava are among the root and tuber crops and can be incorporated in chickens' diet. Substitution of sweet potato in broilers diet enhances feed consumption, growth performance and edible meat characteristics of chickens. Accordingly, addition of sweet potato meal in the ration of chicken causes no any impact on edible meat quality and it may possibly substitute up to 50% maize in broiler finisher ration without detrimentally upsetting production performance of chickens. Besides, the tuber meal of sweet potato can also be incorporated up to 25% in layers ration causing no damaging result on the performance of layer chickens. The tuber of cassava will be cut up and dried up, and milled or pelletized and incorporated in chickens' diet and it can also be included in broilers diet and capable of substituting 50% maize in broilers ration with no adverse effect on their performances and addition of 40% cassava flour or addition of 20% cassava peel meal in layer's ration is pleasing for laying performance of chickens.

Process Optimization for Acid Hydrolysis and Characterization of Bioethanol from Leftover Injera Waste by Using Response Surface Methodology: Central Composite Design

“…Nowadays, the demand for bioethanol is an increase in its volume and consumption [ 8 ]. Ethiopia generates about 192,000 metric tons of leftover injera waste annually, from those around 134,400 metric tons of waste was generated in the southwestern region of Ethiopia especially around Jimma town [ 9 ]. The leftover injera waste is a waste of raw material that is disposed to the environment from restaurants and student cafeteria wastes.…”
