Book Description
Academic Paper from the year 2021 in the subject Environmental Sciences, Haramaya University (Oromia Agricultural Research Institute, OARI), course: Current Topic, language: English, abstract: The current review is initiated with the general objectives of to assess seaweed as animal feed and effect on reducing greenhouse gas emission and health. Multiple issues confront ruminant-based food production today, including environmental emissions, climate change, and escalating food–feed–fuel rivalry for arable land. As a result, more sustainable feed production, as well as the exploration of innovative resources, is required. In addition to the several food industry side streams presently in use (milling, sugar, starch, alcohol, or plant oil), new ones such as vegetable and fruit leftovers are being investigated, however conservation is difficult and output is typically seasonal. As an example of oilseed by-products, lipid-rich camelina (Camelina sativa) expeller has the potential to enhance ruminant milk and meat fat with bioactive trans-11 18:1 and cis-9, trans-11 18:2 fatty acids and decrease methane emissions in temperate zones. Despite the reduced methionine concentration of alternative grain legume proteins compared to soya bean meal (Glycine max), ruminants fed faba beans (Vicia faba), peas (Pisum sativum), and lupins (Lupinus sp.) had comparable lactation performance and development. Although wood is the most plentiful carbohydrate on the planet, temperate zones lack agroforestry techniques to ruminant nutrition. Because of cellulose and lignin connections, ruminants have a hard time digesting untreated wood, although various processing procedures can increase utilization. Fodder trees and shrubs (e.g., cassava (Manihot esculenta), Leucaena sp., Flemingia sp.) provide good protein supplements for ruminants in the tropics. The leaves and by-products of on-farm food production are combined with grass cultivation for ruminant feeding in a food–feed production system. It has the potential to increase animal performance on smallholder farms in a long-term way. Detoxified jatropha (Jatropha sp.) meal is a notable alternative protein source for larger-scale animal production.

Book Description
This study is a first attempt to estimate the impact of a red seaweed (Asparagopsis taxiformis) feed additive on total emissions from cattle and the feasibility of scaling up farmed seaweed production to meet projected demand from the livestock sector. The approach used for the analysis combines projections of supply and demand of beef and milk production to 2050 with a cattle herd model that allows calculation of animal categories by age and sex, animal weight and production, and feed intake and methane emissions from cattle. At the time of this study, the seaweed additive showed limited applicability in grazing systems as it has been used experimentally, mostly incorporated in mix rations for each treatment animal, with not enough evidence available at present to determine the time of decay of the active component in seaweed after consumption by animals with limited access to the additive. Given these limitations, this study assumes that the applicability of the seaweed additive could be extended in the future to most dairy systems via slow-release formulations that have already been developed for other CH4 inhibitors and that can be fed daily during milking time. Based on this assumption, the maximum potential reduction of enteric methane emissions of the new technology is analyzed by projecting a scenario where the seaweed additive is supplied globally to dairy cows. Results show that the seaweed additive could result in a reduction of up to 10 percent in total methane emissions from cattle compared to a No-Seaweed scenario. Most of this reduction was driven by decreased emissions in Latin America, South Asia, and sub-Saharan Africa. The estimated reduction in feed intake associated with the seaweed additive was equivalent to an annual reduction in grain consumption of approximately 50 kgs per cow, or US$5 billion in global cost savings per year. The total amount of dry seaweed needed to supply dairy cows in 2050 was estimated at 5 million metric tons per year, representing 18 percent of the world’s seaweed-farmed area. Simply assuming the sector’s long-term historical average growth rates, this production level might be reached in approximately 20 years, although there are still several open questions about production and technologies and high variability in production costs and producer prices, as A. taxiformis is not extensively produced at present. Available knowledge on seaweed production seems to suggest that, at least at the start, production of A. taxiformis will be by nearshore culture. Expansion of nearshore culture could result in site competition with established seaweed production, access to operational license and government approvals in several countries, licenses to use livestock feeds incorporating seaweed as a feed additive, and more research to demonstrate the safety and efficacy of the additive in accordance with country’s regulations. The best possibilities for the development of production A. taxiformis seem to be in South Asia, for its growing demand and production of dairy products, its importance in terms of global emissions, and its location near the best- and well-established seaweed production areas in Southeast Asia.

Book Description
Livestock production systems are generally considered to have various negative environmental impacts, including nutrient leaching, and a significant contribution to global warming. In this respect, the reduction of gas or ammonia emissions can be achieved through improved efficiency in the choice of feedstuffs. The use of alternative feeds or additives can contribute to a more energy-efficient ration with lower emissions. Such strategies can contribute to improved animal production and health status. Studies have reported that feed additives such as nitrogen-containing compounds, probiotics, prebiotics, and plant extracts significantly reduce ruminant methane. Moreover, research suggested that fruit pomaces could be a low-cost fibre source in poultry nutrition, and that the inclusion of orange pulp in pigs’ diets can reduce the potential ammonia and methane emissions. To properly evaluate the most adequate reuse strategy it is necessary a specific life cycle assessment for each co-product.

Book Description
This Special Issue presents high-quality research papers as well as review articles addressing recent advances in the use of marine bioactives in animal nutrition. The marine environment constitutes a relatively untapped source of biologically active compounds that can be applied in various areas, such as improvement of animal performance, health maintenance, and disease prevention. Numerous marine-based compounds isolated from marine organisms (especially seaweeds) have diverse biological activities, including antioxidative, anti-inflammatory, antibacterial, antifungal, and antiviral activities that can be beneficial to animal health. Additionally, the application of marine bioactives as feed additives can increase the nutritional value of products of animal origin. In this Special Issue, the main attention was focused on seaweeds and their application in poultry (laying hen and broiler chickens) and pig feed. The suitable processing of marine resources required for their optimal use as feed/feed additives was underlined. The contained publications present scientific evidence for the use of various seaweeds as feed additives that improve health (enhanced immunity, prebiotic effect), growth performance, and production. Inclusion of this unconventional material in animal nutrition can enrich products with active compounds, such as micro- and macroelements, polyunsaturated fatty acids, and pigments which are beneficial for consumers.

Book Description
Malaysia has the potential to be a key seaweed production player in the region if proper management and possible interventions take place. Chapter One analyzes the capacity building programs in Malaysia that aim to transform conventional seaweed cultivation techniques to modern seaweed cultivation techniques by applying a scientific approach. Chapter Two studies the marine macroalgae thriving at intertidal rocky shores on the west coast of Portugal, a transition zone where the combined influence of cold waters and warmer waters may favor the development of unique macroalgal communities. In Chapter Three, the authors discuss how problems of environmental deterioration and energy demand could be alleviated by the paradigm shift from fossil to biofuel from marine algae. The chapter elaborates on the unconventional strategies developed for the farming as well as conversion of Ulva rigida to biofuels and biochemicals. Chapter Four discusses the incorporation of macroalgae or macroalgal derived ingredients as a source of both macro-nutrients and micro-nutrients for animal feed production. The biological health benefits of the macroalgal ingredients beyond basic nutrition for the development of functional feed in the aquaculture, the ruminant and the swine sectors are also discussed together with the industrial challenges of its application. To conclude, Chapter Five provides a brief review of seaweed co-culture and its environmental impact on coastal fisheries. First, the current situation and problems facing the coastal fisheries, and the plans to overcome these issues, are discussed. Finally, the positive and negative effects of seaweed culture, role of seaweed co-culture, and the overall environmental impact are addressed.

Book Description
The main effects of Seaweed extracts (Ascophyllum, Fucus, Sargassum, Saccorhiza, Laminaria, Gelidium and others), when used as agricultural fertilizers, are better seed germination and higher quality fruit production, with longer shelf life; better use of soil nutrients; more productive crops and plants with greater resistance to unfavorable environmental conditions. Algae also have a long history of use as animal feed. They have a highly variable composition depending on the species, collection season and habitat, and on external conditions such as water temperature, light intensity and nutrient concentration in water. In relation to ruminal fermentation, a high variability of the digestibility values was found among seaweed species and cannot be attributed only to the composition of different nutrients of the algae. The role of marine algae for reduction of methane production is discussed with particular emphasis on novel algae-based feed strategies that target minimal methane emissions without affecting the functionality of the microbiota and overall animal productivity.

Book Description
Applications of Seaweeds in Food and Nutrition provides an overview on the cultural, biological and engineering dimensions relating to seaweed as a food. With the need for sustainable and healthy foods growing, this comprehensive resource explores how seaweeds can deliver not only nutritional benefits, but also antiviral and antibacterial properties as a food additive and within food processing and manufacturing. Recent developments show that the use of seaweed extracts as a compound can prevent browning. It use in other areas such as a thickening and gelling agents in foods and cosmetics is also encouraging. There are hundreds of different varieties of seaweed known to mankind, yet very little literature is available on the processing of these "crops." This book provides these valuable and practical insights. Introduces the origin of seaweed consumption and its biology Examines common seaweed varieties of industrial interest and their chemical composition Explores the potential of robotics and AI techniques in seaweed aquaculture
