“…The total ME and crude protein (CP) were calculated by multiplying the available DM of feed resources by the ME and CP contents. The values of metabolizable and CP content of different crop residues and by‐products were taken from various sources (Bogale et al., 2008; Feyisa et al., 2021; Feedipedia, 2023; Gudina et al., 2015; Gashaw & Defar, 2017; Getahun et al., 2018; ILRI, 2011; Seyoum et al., 2007). The green weeds and dropped grain during harvesting were taken into consideration, and the conversion factors of 76.5 g/kg and 8.23 MJ/kg CP and ME, respectively, used for natural pasture were used to estimate the values of DCP and ME of fodder obtained from aftermath grazing.…”

“…The values of CP and ME of banana leaves were 77 g/kg and 8.7 MJ/kg, and 74 g/kg and 8.9 MJ values were taken for enset leaves and stem. The CP and ME values of cultivated forage were estimated based on the mean values of 142 g/kg DM and 9.13 MJ/kg DM, respectively, reported for different cultivated forage species (Feyisa et al., 2021 ). The DCP of the feed was calculated from CP according to the formula suggested by FAO ( 1986 ) (DCP = 0.929 × CP = 3.52, where DP is expressed in % DM).…”

BackgroundFeed is a major input in the livestock industry and covers about 60%–70% of the total cost of producing meat, milk and eggs. Inadequate feed supply in terms of quality and quantity leads to lower production performance in livestock. However, the development of an appropriate livestock production strategy through efficient utilization of existing feed resources could raise the production and per capita consumption of livestock products. Efficiency of feed resource utilization can be measured as the ratio between input to production activities and output (e.g. kg of protein used per unit of meat, milk and eggs produced or hectare of land used per unit of milk produced).MethodologyThis study was designed with the objective of evaluating the livestock population and national feed security to enhance livestock productivity in Ethiopia. To achieve this objective, data were collected from the websites of the Ethiopian Central Statistical Agency from 2007 to 2021, FAO publications and websites, books and journals. The data obtained on different feed resources, livestock population and livestock feed requirement and balance were entered into an MS Excel spread sheet (Excel, 2010) and analysed using the general linear model (PRO GLM) procedure of SAS (2014) and multivariate analysis of covariance.ResultsThe study results revealed that the livestock population had increased from 58.31 million tropical livestock units (TLU) to 81.10 million tropical livestock units (TLU), and the emission of entericCH4 had increased from 2511.08 Gg/year to 3661.74 Gg/year from 2008 to 2021. The study results also showed that the major available feed resources for ruminants are natural pasture and crop residues, which account for 56.83% (87.56 × 106) and 37.37% (57.57 × 106) of total feed production in the country, respectively. The contribution of concentrate and improved cultivated pasture and feed from permanent crops used as feed sources is very insignificant (3.05% and 1.96%, respectively). The estimated quantity of these feed resources was sufficient to meet the livestock feed requirement in the country in terms of dry matter (DM), digestible crude protein (DCP) and MEJ, which estimated about 153.31 × 106 t, 4.56 × 106 t and 1203.97 × 109 MJ DM, DCP and MEJ, respectively. The estimated livestock feed requirements were 134.62 × 106, 4.52 × 106, and 918.83 × 109 in DM, DCP and MEJ, respectively. The supply covered about 114.33, 100.04 and 131.33% of the DM, DCP and MEJ total annual feed requirements of livestock in the country. Hence, the current feed surplus obtained on feed requirements of ruminants and equines can support the nutrient requirements of 500 × 106 broilers, about 5 × 106 bulls, about 50 × 106 small ruminants or 3 × 106 crossbred lactating dairy cows, yielding 10 L of milk per day.ConclusionsThe findings of study indicated that natural pasture and crop residues cover a major proportion of the annual feed supply in the country. Therefore, proper grazing management, feed conservation practices, improving grazing land vegetation through clearing invasive species, replacing the grazing land with an improved grass and legume mixture, effective collection, conservation and proper utilization of crop residues, and other alternative options such as the use of chemical, physical and biological treatments to improve the nutritive value of fibrous feed should be practiced. More effective extension services and farmer training are also required to increase feed productivity and, hence, human development.

Environmental productivity index GIS‐based model to estimate prickly pear biomass potential availability for biogas production

et al. 2022

View full text Add to dashboard Cite

Nowadays, climate change is the environmental issue facing the world. To reach the 2030 European Union goals, recently, biogas production through anaerobic digestion has developed significantly, by using alternative biomass sources due to the competition between food and no-food products. In this regard, Opuntia ficus-indica (OFI) has been suggested as a suitable new biomass for producing biomethane within the context of circular economy. In this study, a predictive methodology was applied by combining the Nobel model of environmental productivity index (EPI) and geographic information system (GIS), with the aim of estimating OFI biomass amount, as well as biogas and electricity potential production. The GIS analyses allowed the identification of the most suitable territorial areas for producing biogas from OFI, and an estimation of electricity production. The achieved results are highly valuable information for strategic planning of biogas sector development and could be relevant to the intervention priorities established by the EU.

Fodder development in sub‐Saharan Africa: An introduction

et al. 2021

View full text Add to dashboard Cite

Livestock systems play a key role in the sustainability and livelihood of sub‐Saharan Africa (SSA). The human population in SSA is rapidly increasing, resulting in steady growth in the demand for animal‐sourced foods (ASF). Most current agricultural production practices in SSA coupled with poor management, health challenges and indigenous breeds, result in low crop and livestock productivity and often do not meet local demands. To improve productivity, locally adapted technologies and management practices need to be widely adopted. This special issue is a collection of contributions addressing major aspects of crop and livestock systems in SSA. Key topics addressed include the present status of feedstuff availability in SSA, improved fodder production and utilization practices, new cultivars, soil management, forage conservation, use of near infrared reflectance spectroscopy (NIRS) tools to measure forage nutritive value, and social and economic aspects of crop‐livestock systems. The overarching goal of this special issue is to provide insightful information that can be used for the future development and implementation of efficient and sustainable integrated systems. SSA will have a key role in feeding itself and the world in the future, and livestock systems and cropping practices are crucial components of this process.
