Modern Ruminant Livestock Paradigm: Reducing Methane Production and Increasing Feed Efficiency

The gases in the atmosphere that can capture the sun's heat are called greenhouse gases (GHG). Which includes greenhouse gases in the atmosphere, among others, are carbon dioxide (CO2), nitrogen dioxide (N2O), methane (CH4), and freon (SF6, HFC and PFC). Methane gas (CH4) is a dangerous gas for the earth's atmosphere and one of the greenhouse gas groups above because of the destructive power of methane gas 21 times carbon dioxide (CO2). This requires efforts to prevent methane gas and reduce its production. An example is the use of POME waste or palm oil mill effluent for biogas production. In this way, methane occurring in the open air (aerobic) will be avoided (methane avoidance scenario) and will not be released into the atmosphere with the biogas unit. The livestock sector also has the potential to produce, namely the group of ruminant farms or ruminant animals. The methane is produced in the ruminant's rumen as part of the digestion process. It is estimated that the contribution of methane from ruminant livestock is dominant and of course it needs to be reduced. The production of methane gas (CH4) besides being an environmental problem also causes a lot of energy loss in livestock. And it turns out that there is a process of reducing methane production which simultaneously improves health and increases body weight and milk production.

Large ruminant farms should be more aware of this condition and have a greater incentive to reduce methane production. Biochar is a feed supplement that can be used for the above purposes. The use of 1-3% biochar from dry feed ingredients has been shown to significantly increase body weight gain in beef cattle, as well as milk production in dairy cows. Experiments in Australia on beef cattle for 2 months have given a weight gain of 10% compared to those who do not use biochar. As for dairy cows, it has provided a profit of $ 70,000 per year. For more details, read here. Meanwhile, the reduction in methane gas emissions is estimated at 29% from the use of biochar. Once paddle 2-3 islands, so the saying goes.

Another effect of using biochar as a feed additive is that livestock manure becomes denser and less smelly. Biochar can also be used alone to deal with the smell and viscosity of livestock manure, so that the cage becomes cleaner and does not smell strong. In addition, if the manure is used for production, the biogas production will also increase, for more details, please read here. The composted digestate will also produce better organic fertilizer (compost) because of the additional biochar.

The quality of biochar is also very important, especially for animal feed supplements. Meat and milk are livestock production to meet human food needs, so that it will also affect humans in the end. The quality of biochar is determined by the raw materials used and the production process carried out. This indicates that not all biochar has the same quality, for example biochar from agricultural wastes with high ash content with traditional processes, with wood biomass raw materials with a small ash content and modern processes, of course the results are different, for example using the same modern technology will have different results. The differences mainly lie in their physical chemistry properties.

Biochar production should also be designed according to its objectives, for example the biochar feed supplement above must use selected biomass raw materials and modern processes so that the quality is stable and maintained. Meanwhile, the reference for biochar quality can be OMRI, USDA or IBI. World feed livestock associations or organizations such as FEFAC, IFIF and AFIA are currently very concerned about safety and sustainability, so this can be in line with biochar as a feed additive. Biochar as a feed additive, especially dairy cattle, has been accepted by almost all European Union countries. Meanwhile, for purposes such as reducing odors and the dilution of impurities, biochar is produced from any biomass and even by using simple technology (low tech).

Food Energy Water for the World Community

"There will be no doomsday, until wealth has been piled up and abundant, until a man goes everywhere carrying his zakat but he does not get anyone who is willing to accept his zakat. And so that the Arab lands become fertile again prosperous with meadows and rivers "(HR.Muslim).

The earth will once again prosper before doomsday. In general gardens and forests like that also cause springs to appear (QS 36: 34) which in time will flow into the rivers (QS 19: 24-25) and also be your pleasure and your animals ( QS 79: 31). Basically, the earth is very sufficient to meet human needs, especially in 3 main things namely food, energy and water. In the era of bioeconomy that is believed to be in sight and we will soon experience it, a number of technologies will be developed to support these three main sectors in a sustainable manner. The emphasis on something that is sustainable  is increasingly emphasized to increasingly abandon or not at all use fossil sources (fossil free), especially in the energy sector. It is this aspect of sustainability that clearly distinguishes the fossil economy era from bioeconomy.

The Concept of Energy Plantation and Verticulture 

The tropics will be excellent for developing bioeconomy because of the availability of sunshine throughout the year. This tropical region will compete for entrepreneurs engaged in this sector, such as the African continent and Indonesia. The availability of vast land in the area is a key factor in the development of energy plantations. Energy is a vital need for human kind today, especially to drive economic sectors. With energy plantations, massive energy needs can be met. Fast rotation and coppice plants such as calliandra and gliricidae are the mainstay of energy plantations. In addition to the energy plantation will be able to conserve water, livestock business can also be developed by utilizing leaves waste from the energy plantations. Sheep, goat or cattle farms are ideal for utilizing leaves waste from the energy plantations. Honey bee keeping can also be developed by utilizing flowers from the energy plantation.

Tall buildings were built not even for human habitation, but as agricultural land for food crops (verticulture). Verticulture farming is to meet food needs and facilitate its management. Modern farming techniques are used to maximize the quality and productivity of the farm. To support the success of agriculture, IOT (internet of things) with a number of sensors that can be read online is an integral part of agricultural management. The effectiveness and efficiency of farming can be increased rapidly so that high productivity and quality can be achieved, while large lands mainly for energy plantations. Biochar which can be used to improve the effectiveness and efficiency of fertilization can be applied to verticulture farming.  Apart from being made compost agricultural wastes can also be partially converted into biochar. For large capacity biochar production, the continuous pyrolysis units are the best choice. Compost and biochar production also makes the farming practices zero waste. Even with continuous pyrolysis technology, in addition to biochar, heat and electricity can also be produced. Liquid fuel namely biooil, is also produced from the continuous pyrolysis technology.

With the majority of land used for energy plantations, the energy needs, InshaAllah, can be fulfilled even the meat needs of the livestock business, as well as food production with verticulture. The ideal concept, if it can be implemented, should be a solution to the problems of life today. The concept can be implemented if humanity realizes the importance of the program and supports it. Technically, this can be done, and some have done it even on a smaller scale and it has not been fully integrated.

The coming era of bioeconomy should also be in line with the improvement of the economic system that gives a sense of justice to the world's population. With the current economic model it takes 800 years for the bottom billion people to reach 10% of global income. As a result of the current liberalism and capitalism, the richest 10% control 85% of global wealth. The three richest people in the world have assets of more than 47 GDP, the lowest gross GDP. 1% of the richest people own more than 50% of the world's wealth. This huge inequality should be overcome immediately with a equitable and prosperous economy. The transition from fossil economy to bioeconomy can be both an medium and a momentum for improving the economic system. The tropics, which were previously of a minor economic role, should have been increased and taken into account or even become a major player in the bioeconomy era.
