Global Strategies to Minimize Environmental Impacts of Ruminant Production

Abstract

Demand for ruminant products (dairy products, beef, and sheep meat) is increasing rapidly with population and income growth and the acceleration of urbanization. However, ruminant animals exert the highest environmental impacts and consume the most resources in the livestock system. Increasing studies have focused on various measures to reduce ammonia, greenhouse gas emissions, and resource depletion from ruminant production to consumption. This review offers supply- and demand-side management strategies to reduce the environmental impact of ruminant products and emphasizes the mitigation potential of coupling livestock production with cultivation and renewable energy. On a global scale, more attention should be paid to the green-source trade and to strengthening global technology sharing. The success of these strategies depends on the cost effectiveness of technology, public policy, and financial support. Future studies and practice should focus on global database development for sharing mitigation strategies, thus facilitating technology innovations and socioeconomic feasibility. Expected final online publication date for the Annual Review of Animal Biosciences, Volume 10 is February 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Collaborative Green Innovation of Livestock Product Three-Level Supply Chain Traceability System: A Value Co-Creation Perspective

“…He also provided a practical method for evaluating green suppliers using discrete Hopfield neural networks. Du et al [20] introduced supply-side and demand-side management strategies aimed at mitigating the environmental consequences of ruminant products, underscoring the potential of integrating livestock production with cropping and renewable energy. While prior research has predominantly centered on distinct innovation types, there is a notable gap in studies examining the collaborative greening of the livestock product supply chain.…”

Raising sheep in environmentally friendly conditions of Eastern Transbaikalia

“…The genetic diversity of sheep of each breed can provide more than 2 genetic types. It is necessary to take into account these data in order to increase the productivity of sheep, as well as to improve the breeding base [1].…”

Regulation of Dietary Protein Solubility Improves Ruminal Nitrogen Metabolism In Vitro: Role of Bacteria–Protozoa Interactions

“…With the rapid development of the modern economy, the demand for high-protein food sources is increasing year by year, and beef, mutton, and dairy products (especially ruminant products) seem to be the first choice for most consumers [ 1 , 2 ]. However, ruminant production is one of the main drivers of global environmental degradation, and the contribution to environmental pollution is much greater compared with non-ruminants [ 3 , 4 ]. Ruminants account for over 70% of global livestock ammonia (NH 3 ) emissions and around 30% of total anthropogenic NH 3 emissions, resulting in significant economic losses and negative human health impacts [ 5 , 6 ].…”
