Nutrition to help tackle the challenge Proper nutrition, welfare and health management are essen- tial in helping tackle this challenge but, without them, live- stock production efficiency can decrease by as much as 30%. By taking action, farmers are not only fighting emissions but are keeping themselves and their animals alive and well, all while reducing the significant operational and economic costs associated with replacing livestock due to ill health. This still raises the question: How can emissions be cost-effec- tively reduced from swine farming? Interventions are availa- ble that span the whole life cycle of manure production, cre- ating a variety of ways to limit the ammonia, nitrous oxide, nitrates and phosphorus that swine excrete. Foremost among these is altering their diets. By improving the utilisation of nitrogen, for instance, it is possible to ensure that less exits the pig in its manure. Statistics show a staggering 50% or more of the nitrogen fed to pigs is not utilised but lost to the environment while improving the animal’s health. That highlights the need for a feed-based approach, reducing the amount of ammonia produced in manure without requiring expensive handling or manure treatments.


Improving sustainability DSM aims to improve the sustainability of animal protein production through a strategic initiative called We Make It Possible. Underpinning this initiative are six sustainability


platforms, one of which is to reduce emissions from livestock. The sustainability platform is in direct support of the UN Sustainable Development Goal 13, Climate Action. For this to be realised, animal agriculture must reduce the emissions it produces, cutting the levels of methane and nitrous oxide entering the environment both directly and indirectly, but also reducing ammonia emissions. DSM has developed solu- tions that make the production stage of the value chain more emission friendly. VevoVitall is a safe and ultra-pure source of benzoic acid for livestock use that is easy to handle, with low odour and corrosion. It lowers ammonia emissions from livestock and at the same time gives swine farmers the fast-growing, efficient, healthy and profitable animals they need. The reduction in ammonia emissions that resulted from adding benzoic acid to the diet of growing-finishing pigs averaged 15.8% compared to a diet without this acid. Feeding VevoVitall to all swine worldwide could save the planet an estimated 250,000 tonnes of ammonia emissions. By reducing ammonia emissions in species like swine, it is thus possible not only to improve the welfare of animals, helping farmers maintain profitable and sustainable opera- tions, but also to reduce harm on our environment – a true win–win for everyone.

Keeping the air in pig houses clean is also beneficial for finishing pigs.
