Description

Method for measuring greenhouse gas emissions of ruminants after feed additives are administered Cross Reference to Related Applications The present application claims the benefit of U.S. provisional application serial No. 63/536,816 filed on 6/9/2023 in 35 u.s.c. ≡119 (e), the entire disclosure of which is incorporated herein by reference. Background of the inventiondescription of the invention In the modern world, there is a great demand for mechanisms for reducing greenhouse gas emissions. The mechanisms studied are extensive and profound in nature. Therefore, almost every technical field faces challenges, taking measures into account to potentially reduce its "carbon footprint" in an effort to embody environmental awareness. In the agricultural and food fields, the reduction of greenhouse gases such as methane has been studied. In an effort to reduce emissions of greenhouse gases such as methane emitted by animals, various active ingredients have been developed that can be fed to animals. Specifically, feeding monensin (monensin) (RumensinTM) and 3-nitrooxypropanol (BovaerTM) to animals can achieve a reduction in greenhouse gas emissions produced by the animals, particularly ruminants. Furthermore, the availability of carbon credits provides an incentive for farmers and producers to reduce greenhouse gas emissions. Therefore, there is a need to minimize greenhouse gas emissions in animal husbandry in order to qualify and obtain desired carbon credits. Accordingly, the present disclosure provides methods for administering monensin and/or 3-nitrooxypropanol to an animal to provide a reduction in greenhouse gas emissions by the animal. Furthermore, the described method provides an embodiment for generating and receiving carbon credits due to the reduction of greenhouse gas emissions. Monensin (also known as RumensinTM) is a feed additive approved by the U.S. food and drug administration veterinary center (U.S. Food and Drug Administration Center for VETERINARY MEDICINE) for improving milk production efficiency, defined as the production of marketable, solid correction milk per unit of feed intake that corrects for weight changes. For example, in growing cattle (including replacement gilts), monensin increases the rate of weight gain and also prevents and controls coccidiosis. Monensin increases milk production efficiency of cows by transferring rumen bacterial groups to produce more propionate, which is a more efficient use of feed raw materials because the amount of energy consumed as carbon dioxide and methane is reduced. Figure 1 summarizes the adjustments used to quantify the effect of monensin on greenhouse gas emissions. The use of monensin in lactating cows significantly reduced Dry Matter Intake (DMI) by 2.3% and increased milk production by 2.3%. Because of the significant heterogeneity observed in the milk fractions, the reported yields and component percentages can be used to calculate the Solids Corrected Milk (SCM) difference between the control and monensin treatments according to NRC 2001, resulting in a 0.5% increase in SCM with monensin. Thus, a 0.5% conservative positive increase can be used for the monensin effect on both SCM and milk yield. For dry cows (dry cow), the monensin test has demonstrated a 2.7% reduction in dry matter intake. The mode of action of monensin on milk production efficiency results in reduced methane production. The effects of feeding monensin to cattle include direct reduction of CH 4 emissions from intestinal fermentation and indirect reduction of intestinal fermentation emissions by DMI reduction, while having no negative impact on health and positive benefit on milk production. The sustained benefits of feeding Rumensin to cattle are supported by a number of scientific studies that have measured the reduction in CH 4 emissions resulting from intestinal fermentation. Because of the effect of monensin on reducing DMI, the greenhouse gas effects of feed planting and manure are also reduced, thereby providing additional greenhouse gas benefits. These effects are accounted for by the processes and calculations in the present protocol. Monensin reduces absolute emissions in the production of consumer products along the value chain. Intestinal methane is produced by fermentation of feed that is regularly consumed by animals during the day. Since monensin works by reducing intestinal methane and feed intake, the reduction in greenhouse gas emissions associated with feeding monensin is permanent and irreversible. Intestinal methane released into the environment increases by 3-5% per day without feeding monensin to the animals. Furthermore, a number of peer-reviewed documents indicate that depending on the dosage and diet, 3-nitrooxypropanol (also known as 3-NOP or BovaerTM) can reduce intestinal methane emissions by about 30% or 1 Metric Ton (MT) CO 2, which can be modeled to provide a more accurate estimate of reduction. Assuming that the intestinal methane production
