The use of oregano (Origanum vulgare L.) in dairy cattle for the reduction of greenhouse gases from
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
Your profile as an entrepreneur
My name is Leticia Godoi Rosa, I'm 19 years old, and currently I'm studying Veterinary Medicine at the Federal University of Santa Catarina (UFSC). From 2016 to 2018 I took the technical course in agriculture and livestock at IFC Rio do Sul. I had the opportunity to participate in the FETEC - Technical and Scientific Knowledge Fair, presenting the project here. She was a great success during the course, being considered one of the best students of the institution by teachers and teachers. I have a high degree of technical knowledge in the area of the bavinocultura and its environmental impacts regarding the greenhouse effect. In 2018, I completed a traineeship at the State University of Santa Catarina (UDESC), working on two research projects that had the same guidelines for evaluating the emission of greenhouse gases by cattle. I have great dedication to the area of research aimed at improving the socio-environmental aspects of the planet allied to animal production, an area in which I have a passion for studying and acting. I have excellent background and recommendations from recognized professionals in Brazil. I have a diploma of outstanding student and better in intelctualidade in the Program of formation of Environmental Protectors, I seek to make use of individual and collective actions to improve the quality of life and the sustainability in the nations with the help of technology and the ethics with motivation, persistence and knowledge I believe that I can change the world and contribute directly to change.
