Acacia Wood Extract as Feed Supplement to Successfully Reduce Methane Gasses in Livestock
The impact of global warming which is increasing Earth’s temperature can be seen from a decline in the productivity from both agricultural and the animal husbandry sectors. If left without intervention, global warming could threaten food security. On the other side, the animal husbandry sector also contributes to global warming. The greenhouse gasses produced from the animal husbandry sector contributes to 24% of the total greenhouse gasses, while 16% of that number is made up methane gasses. In total, animal husbandry is the second biggest contributor of greenhouse gas emissions in the world and the accumulation of methane gasses are on the rise. This was described by Dr Anuraga Jayanegara in the Webinar titled Potential of Green Business in the Animal Husbandry World held by Terbuka University’s Faculty of Science and Technology on the 10th of March 2021.
Dr Anuraga who is an expert of livestock feed technology mentioned that the environmental issue relating to methane emissions is one of the main issues in animal husbandry. Besides causing global warming, methane gasses also cause a loss of livestock energy as many as 4 to 16%. If it is possible for the process to be reduced, then livestock productivity could be increased.
According to Dr Anuraga, there are three important stages to reducing methane gasses in animal husbandry. Those steps are reducing the production of hydrogen, to look for alternatives of hydrogen, and to hinder the methanogens which are the microbes producing methane gasses. The mitigation of emission is first done by using a natural adaptive substance called polifenol which could be extracted from the acacia bark. This substance functions as an antimicrobe which hinders the methanogens. This research has been worked on since 2008 until now, and the results are that methane gasses will decrease when the livestock’s feed is mixed with polifenol.
He explained that the addition of polifenol would create a synergic effect. When methane gasses decrease the livestock value would improve both in quality and quantity. The first benefit is that the daily weight per animal would increase to about 0,35 kilograms. The use of polifenol has also increased farmers’ incomes by 500 IDR per kilogram of feed. The polifenol extract increases the quality of farm products. The decrease in methane gas reduces saturated fatty acids which is dangerous for health in high quantities. The meat produced will contain more unsaturated fatty acids good for health. Therefore, the quality of meat produced will increase along with this innovation.
The waste products of acacia processing contain high polifenol which can be used in the supplementation of livestock feed. The substance is extracted from pieces of wood waste products by boiling at a high temperature and utilizing the water used to boil it. The next step is to make a flour out of it and extracted until ready to use in a liquid form. The research team is continuously innovating so that their innovations could be used by the public. One of these efforts is to disseminate the innovation working together with institutions in the animal husbandry industry. Besides that, they are also participating in expos aimed to introduce innovations in livestock technology. A collaborative effort is needed so that this innovation could be developed and implemented by the general public.
