Reusing what you already have


Keeping nutrients in the food chain


Encourage the use of novel feed


Upgrading food leftlovers to valuable feed ingredients

Welcome to SAN, the digital platform focused on studies and researches on Sustainable Animal Nutrition (SAN).

Here you can find the main projects developed by an international research team aimed at identifying alternative forms for animal nutrition, which can have less impact on the environment and promote the well-being of animals and men who eat.

 The concept of sustainability in animal nutrition is meant to reduce both feed and food wastes. Livestock production systems have received growing attention in recent years since they have clearly been identified as a deep environmental impact factor. Moreover, cost of animal feed represents up to 85% of the farm gate value of several farm animals. From this perspective, sustainability in livestock productivity cannot be achieved without using sustainable animal diets

In fact, livestock systems today and in the future have to take into account not only economic development, feed security and safety, but also politically-sensitive issues such as animal welfare and environmental sustainability. Accordingly, the main aim of the project is to develop a “sustainable animal nutrition” concept.

How the environment can benefit by feeding pigs leftover pasta and biscuits

Agriculture accounts for 70% of the available freshwater supply and roughly 30% relates to the livestock sector (Hoekstra and Mekonnen, 2012). Similarly, around half the world’s agricultural area and 40% of all arable land is used for livestock feed production and...

Insect in animal nutrition: the next step

The increasing global need to find alternative protein/energy sources encouraged and promoted the research in the field of non-conventional nutrients. Insects, algae, ex-food (also termed former food products) as well as duckweed are looked as an interesting...

Salad leaves in dairy cow feed for “greener” milk

The consumption and supply of water are increasingly constantly, creating not only water availability issues, but also competition among industrial, domestic, agricultural and energy uses (Krasna, 2019). Agricultural uses dominate in terms of the appropriation of...

Livestock system: potential, challenges and future directions

Water Saving Using Leafy-Salad Waste As Animal Feed For Dairy Cows In Italy

Over the last few decades, water consumption and supply have steadily increased, creating not only water availability issues but also a competition between the uses of the resource, among industrial, domestic, agricultural and the energy use. By analyzing the several...

SUSTAIN CIRCULAR ECONOMY. Keeping nutrients in the food chain

FAO forecasts predict that by 2050 the world population will reach 9,7 billion people. This means that food requirements will consequently increase: in order to supply these growing needs, food waste and the current competition for raw materials between humans and...
