“…Steers fed RAC vs. control rations showed lower NH 3 emission by 17.21% from d 0 to 28 (p = 0.032) and a trend for lower emissions from d 0 to 42 by 11.07% (p = 0.070). Ractopamine simultaneously increased beef cattle performance reduced NH 3 emissions [100].…”

“…β-AA promotes protein synthesis in livestock, reducing N excretion. The reduced N excretion mitigated NH 3 emission (11 to 17%) from β-AA feeding [100]. Ross [100] conducted an experiment to determine the efficacy of feeding ractopamine hydrochloride (RAC) for the last 42 days of the finishing period to reduce NH 3 emissions and improve animal performance.…”

Northeast Colorado’s livestock operations have been identified as a major contributor to reactive nitrogen deposition in the Rocky Mountains National Park (RMNP). We present a review on the state of knowledge concerning the emission, transport, deposition, and mitigation of gaseous ammonia (NH3) from open-lot cattle feeding facilities located east of the Northern Front Range of the Rocky Mountains. Gaseous NH3 mitigation strategies discussed are related to diet manipulation and management practices. Crude protein content of 11% and condensed tannins of 8% reduced the NH3 emission by 43% and 57%, respectively. Ambiguous results for NH3 mitigation by using water sprinklers have been reported—an increase in NH3 emission by 27% and decrease of 27 to 56%. Manure harvesting should be evaluated in terms of maintaining proper moisture content, and not necessarily as a mitigation option. The use of chemical and physical manure amendments has shown a wide range in NH3 mitigation effectiveness, ranging from 19 to 98% for chemical and 0 to 43% for physical amendments, respectively. The review outlined the scientific basis, practicality, and expected efficacy of each management practice. The most plausible management practices to reduce NH3 emissions from corral surfaces in cattle feedyards are presented.

“…This combination significantly enhances manure management, a key factor in the generation of methane and ammonia emissions [40]. The effectiveness of these systems lies in their ability to rapidly remove manure, thus limiting its exposure to air and significantly cutting down on the emission of noxious gases [41,42]. The reduction in ammonia volatilization is particularly notable, as the frequent removal of manure inhibits the enzymatic processes crucial for the transformation of urea in manure into ammonia.…”

In recent years, the Canadian dairy sector has faced escalating challenges due to its significant contribution to greenhouse gas emissions, particularly methane. This paper critically examines a spectrum of innovative techniques aimed at mitigating methane emissions within this sector, scrutinizing their cost-effectiveness, efficiency, compatibility with animal welfare standards, and adherence to both existing and prospective Canadian environmental legislations. The discourse begins with an exhaustive overview of contemporary methane reduction methodologies relevant to dairy farming, followed by a rigorous analysis of their economic feasibility. This includes a detailed cost-benefit analysis, juxtaposed with the efficiency and technological advancements these techniques embody. A pivotal aspect of this examination is the alignment of animal welfare with emission reduction objectives, ensuring that the strategies employed do not compromise the health and well-being of dairy cattle. Furthermore, the paper delves into the legislative landscape of Canada, evaluating the congruence of these techniques with current environmental laws and anticipating future regulatory shifts. Performance indicators for emission reduction are critically assessed, establishing benchmarks tailored to the Canadian context. This is complemented by an exploration of the market potential of these innovations, including factors influencing their adoption and scalability in the market. The analysis culminates with a synthesis of case studies and best practices within Canada, offering insights into successful implementations and drawing lessons for future endeavors. This comprehensive approach not only addresses the immediate environmental and health impacts associated with dairy farming emissions but also significantly contributes to the overarching goal of sustainable development in the agricultural sector. The research presented in this paper holds significant implications for the future of sustainable dairy farming, offering a model for addressing environmental challenges while maintaining economic viability and animal welfare.

“…The researchers opined that future work should focus on understanding the effects of long-term supplementation or high dose of 'SOP STAR COW' to regulate mitigation effects on methane emissions and increase in milk production can be ascertained. In another report, Ross et al [9], by adopting various free-stall management techniques studied the means to lessen ammonia, greenhouse gas, and some air pollutants from lactating dairy cattle wastes. From the study, it was concluded that removal of dairy manure by 'scraping' holds a high prospective to enhance gaseous emissions such as ammonia and other greenhouse gases.…”
