Facial recognition could be used on pig farms in China to provide individualised feeding plans. The artificial intelligence system, created by a subsidiary of Chinese e-commerce company JD, can also track a pig’s growth, physical condition and vaccinations over its lifespan.
A new method for monitoring nutrient concentrations in pasture in real time - using a small near-infrared spectroscopy device - could allow farmers to improve productivity by adjusting livestock grazing patterns, according to this paper.
This report by the RISE Foundation (Rural Investment Support for Europe), co-authored by FCRN member Elisabet Nadeu, outlines the environmental and health impacts of livestock production and consumption in the EU. The report suggests that there is a “safe operating space” for livestock production, defined at the lower bound by the provision of nutrition to humans and the maintenance of permanent pasture habitats, and defined at the upper boundary by climate impacts and nitrogen and phosphorus emissions.
A case of bovine spongiform encephalopathy (BSE), also known as “mad cow disease”, has been confirmed on a farm in Aberdeenshire. The case was discovered before entering the human food chain, and Rural Affairs Minister Mairi Gougeon has said that all necessary measures have been taken to protect consumers.
Government policies are not doing enough to support the transition to a lower-carbon foods sector, according to a report by the Changing Markets Foundation. Specifically, the report argues in favour of policies to shift the food system away from animal agriculture and towards plant-based foods.
The Food and Agriculture Organisation of the United Nations has released the report “Transforming the livestock sector through the Sustainable Development Goals”, which examines how the livestock sector interacts with each of the Sustainable Development Goals, including synergies, trade-offs and complex interlinkages.
FCRN member Christopher Schlottmann and Jeff Sebo, both of New York University, have written a book discussing empirical, ethical, and social dimensions of food, animals, and the environment, providing both big picture and more detailed analysis, including updated statistics.
The Food and Agriculture Organisation of the United Nations has published guidelines for the assessment of nutrient flows and their associated environmental impacts in livestock supply chains. The guidelines are aimed at people and organisations who already have a good working knowledge of life cycle assessment of livestock systems, and are intended to promote consistency through defining calculation methods and data requirements.
In this study, researchers investigated the views of urban Brazilian citizens on dairy production. The study also explored the public’s awareness of and their views on the acceptability of four common husbandry practices: early cow-calf separation; zero-grazing; culling of the newborn male calf; and dehorning without pain mitigation. Their goal was to understand Brazilians’ concerns around and acceptance of dairy farming.
If the US were to shift to entirely grass-finished beef (vs. grain-finished), then the US cattle population would have to increase by 30% relative to today, because grass-fed cattle gain weight more slowly than those fattened in feedlots. Furthermore, existing pastures would have to become 40%-370% more productive to avoid converting more natural habitat to farmland or competition with human food supply. Methane emissions from the cattle’s digestive systems might increase by 43%, again because of slower growth rates.
Writing in the Guardian, Isabella Tree of Knepp Castle Estate argues that vegan diets ignore the potential of wildlife-friendly livestock grazing methods. Tree claims that not using anti-worming agents or antibiotics allows cow dung to feed various soil organisms, contributing to soil restoration and wildlife diversity.
New Zealand’s Parliamentary Commissioner for the Environment has released a report exploring how much and over what timescale the climate is affected by methane emissions from livestock. It focused on two questions. First,if methane emissions from livestock were held at current levels or followed business-as-usual trajectories, what would their contribution to future warming be? Second, what reduction in methane emissions from livestock would be needed so that they cause no additional contribution to warming?
A new paper has estimated the economic and environmental potential of feeding livestock with industrially-fermented microbes such as bacteria, yeast, fungi and algae instead of crop-based feed. The study finds that microbial protein could replace 10-19% of crop-based animal feed protein, with decreases in land use, climate impact and nitrogen pollution.
This paper, by FCRN member Hannah van Zanten (and whose authors include FCRN director Tara Garnett), calculates that a food system where livestock are fed only on food waste and industrial and agricultural by-products could provide 9 to 23 g of animal protein to the daily human diet (compared to daily protein needs of 50 to 60 g per person) while using one quarter less land than a food system with no livestock. The paper notes that the waste-fed livestock system could allow people in Asia and Africa to increase their consumption of animal protein, but that current consumption levels in other areas are higher than would be possible under a waste-fed livestock system.
Sixty suppliers of meat and fish have been ranked according to their management of nine sustainability categories, in an index prepared by Farm Animal Investment Risk and Return (FAIRR), a London-based investor initiative focused on the environmental, social and ethical issues of factory farming. 60% of the companies assessed are deemed “high-risk” on their overall sustainability strategy (or lack of it). Antibiotics are the most poorly managed risk, while waste and pollution are the best-managed risks.
This book, by Henry Buller and Emma Roe, examines issues of animal welfare in the food supply chain. Topics include the care of farm animals, the ethics of using welfare as a marketing tool and the links between globalisation of farm animal welfare.
