Explain your project in details:

Emissions of gases such as methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O) have now intensified through the agricultural sector. The high concentration of these gases causes the greenhouse effect, that is, the destruction of the ozone layer in the stratosphere, generated by heating the earth's surface. In cattle, methane production comes from the digestive process of ruminants, in which the fermentation of the carbohydrates of the ingested vegetable mass is carried out by ruminal microbial beings, through an anaerobic process (without O2) to which the formation of the fatty acids occurs through the conversion of the cellulosic carbohydrates. Ruminants globally produce 80 to 103 million tonnes of methane per year, which accounts for 25% of the methane produced by mankind (HOWDEN and REYENGA, 1999). Oregano has a good antioxidant and antimicrobial capacity against microorganisms and pathogens (LOZANO, CYNTHIA, 2004, p.1). Thus, it is expected that ruminal modifier will be present due to its components, such as carvacrol and thymol, thus reducing the emission of such gases. The methods used for the measurement of CH4 in animals are closed chambers made of PVC tubes, which have been described in Lockyer (1997) and in the United States (1990). For animals raised in an extensive pasture system, Johnson and Johnson (1995) developed the technique using sulfur hexafluoride (SF6) as the internal tracer gas. This technique involves the placement of a permeation tube, which releases SF6 at a previously known rate, into the animal's rumen, and CH 4 and SF 6 samples are collected in the vicinity of the animal's mouth and nostril. The flow of CH4 released by the animal is calculated in relation to the flow of SF6 (WESTBERG et al., 1998). The objective of this project is to quantify from the use of oregano oil, the reduction rate of greenhouse gases.

Impact of your enterprise on sustainable development

Being in daily contact with scientific activities regarding livestock production and its observation regarding contributing factors for the greenhouse effect, together with the opportunity to work with highly specialized professionals within universities of great importance, provides a wide view on the aspects to be considered when we are talking about high milk production and its management in order to mitigate to the maximum environmental impacts that it enlarges. I emphasize that: the agricultural sector is, by me, considered a highly scientific field, which measures towards new forms of sustainable management + high production + animal welfare + GHG reduction ,, means to expand research and projects to obtain results of the enlargement and modernization of this sphere, which is undoubtedly of great economic importance in the world. Therefore, the incentive to research with certainty must remain a priority when it comes to the training of large professionals, both agricultural and agricultural, if in matters of complementing the knowledge acquired in educational institutions, so that these two variables will be able to be in a thin line between agriculture, agriculture and livestock, science and technology and, more valuable still, sustainability, improving the environmental, sociological and climatic aspects of the planet.

Sustainability and future plans

The experiment consisted of the addition of oregano (Origanum vulgare L.) in the diet of lactating Jersey cows. The research will be carried out with two groups of cows, containing 11 animals in each group. Two differentiated treatments will be carried out, in which, in the first moment, the bovine will already have a bundle with the equipment attached, and the daily diet will continue unchanged. After this period, the animals will go through a 12-day adaptation period, which will add oregano to the diet, at a concentration of 1% of the total daily consumption, noting if it will remain in homeostasis, verifying animal welfare. For the capture and measurement of gases in both treatments, it is necessary to use an apparatus made with PVC pipes, next to a pressure valve (canga), used since the beginning of the experimental process. This canga is subjected to a vacuum and inserted in the neck of the animal. A tube connected to the canga valve and animal halter is placed so that its end is located near the bovine nostril. Resulting from the pressure difference, the air returns from the nostril and mouth, and is sucked into the canga, this airflow is controlled by the capillary tube, thus causing the equipment to be replaced every 24 hours, calculating the volume of internal air, and (SFH) (Sulfur Hexafluoride). The results of this study are based on the results obtained in the literature. This procedure will be repeated for 10 days. It is expected that funding will not be provided through public institutions to contribute to the generation of articles, materials and scientific data for the publication and subsequent implementation of the system in the world's largest flocks to achieve the goal

Hello Leticia

Your project is good. However, i think you still need to improve on your traction (impact of your enterprise on sustainability development); for any ongoing project, as Entrepreneurs; traction is like our success story and shows our progress and also has a positive impact on investors to be and we your clients / customers. Providing statistical evidence will be a good edge against selection criteria. Best of luck

This project is one that addresses one the the 2 most problematic parts of climate change, the agriculture industry. I think that this experiment is a good way of coming to a solution to the problem. The fact of natural solution is also good because it can become a healthy alternative to an industry riddled with chemicals. The experiments will most certainly address few of the development goals. I would check as well how sustainable this oregano growth can be as well. best wishes

It is very clear that we have polluted our environment all the way to the ozone layer. This has caused drastic climatic changes all over the world. To evade catastrophe linked to ozone layer depletion we need intervention. Congratulations for starting us off. Who would have thought of it your way! I can see that your organisation was launched in 2009. Have you been conducting other researches related to this? Good work. So after you get the results of your experiment, what will be the way forward for you? How will you ensure other farmers improve their dairy farming practices? My questions are just to help you ponder on your project a little bit. I wish you well.

Hi Rosa,

You have my vote! if not for anything but for the fact that you are just 19 years old and you are into agriculture; livestock farming to be precise. This is one area I love so much. Agriculture is one of the sectors that have been forgotten by our leaders and majority of the youths are now running after 'white scholar job' forgetting the unending importance of agriculture. Some countries like Tanzania, Nigeria, etc are really trying their best when it comes to agricultural education and their citizens are really making it big. My country (Nigeria) for instance has actually launched an agricultural empowering program where graduates who are still in the job hunt are employed, trained and send to the uneducated farmers to impact them on how to improve their agricultural produce, and this has been impactful. So Rosa, you can actually imitate or learn from their procedures. K
