Alltech ONE discusses how to feed the future
One of the topics addressed at the recent virtual Alltech ONE ideas conference was how to feed our livestock in the future. Several speakers discussed how to take into account the animals’ carbon footprint, sustainable feed sources and human and animal health, while producing enough food.
Higher milk production, lower carbon hoofprint
Dairy production is growing across the world at a rate of 25% but with this increase come greater sustainability challenges. Dr Saheed Salami, research fellow at Alltech, outlined some of the main sustainability challenges farmers face at the Alltech ONE Ideas conference. He said: “Greenhouse gas emissions are a top topic now. And I think with the Joe Biden Climate Summit recently, that issue is resonating more in the industry, especially when it comes to reducing greenhouse gas emis- sions from the livestock chain. “It’s very clear that going forward things are not going to be business as usual; the dairy industry have to adapt to these changes.” Dr Salami recognised that the dairy industry produces the second largest sources of emissions in the livestock sector. He added: “So what we see is that enteric emissions from the rumen and feed use actually contribute to
the two largest sources of emissions on dairy farms, which contribute over 60% of total emissions. “We still have other sources of emissions like manure, which is ni- trous oxide specifically, and also ar- tificial fertiliser and the use of electric- ity. But of course, we know that if we are to achieve a more sustainable dairy farm, we need to focus on all of these aspects on the farm so that we can reduce emissions. “More specifically reducing enteric methane and feed use of- fers a big opportunity for us to reduce greenhouse gas emissions,” he said.
Feeding your future: the changing face of aqua feed
The growth of the aquaculture in- dustry is accelerating globally. The challenge is the fact that the avail- ability of fishmeal is limited. The industry is trying to monitor fish- meal demand to ensure that there is enough supply and new alternatives to fishmeal are being investigated.
Speaking at the Alltech ONE ideas conference,
Ben Lamberigts, research and nutrition manager, Alltech Coppens, said the fishmeal challenge has to be solved before the industry can grow. Since the 1990s the industry has been reducing the FIFO factor (Fish

In, Fish Out), which basically is the number of wild caught fish needed to produce one kilogram of farmed fish. Ben said: “Globally, we are producing 45 million kilograms of farmed fish. This is the sum of the 11 most important farmed species in the world. To produce this 45 million kilograms of aquacultured fish, we still need 12 million kilograms of wild caught fish to use as fishmeal in our fish feeds. “If we divide these two, we have a FIFO factor of 0.27. That means that with one kilogram of wild caught fish we are able to produce 3.7 kilogram of farmed fish.” Other sources of fishmeal include haemoglobin, blood meal or poultry meal, which are animal byproducts. Also sunflower meal, wheat pro- tein and soy products are vegetable protein sources. And there are in- sect meals such as meal worms or black soldier fly meal.
