“Inclusion of Uniprotein® in the feed leads to increased digestion and utilisation of the nutrients for both fish and monogastric animals" meal with replacement of fishmeal on a one-to-one basis have also been shown to increase the survival rate from 84 percent in the control group to 93-97 percent in the group with 100 percent replacement of fishmeal with bacterial protein meal. Also, growth was improved in terms of total shrimp weight in all bacterial protein meal diet groups, showing equivalent to or improved growth compared to the control diet group10. Other monogastric animals such as pigs, broilers, mink and dogs have also shown some positive responses in relation to health and digestion when fed with bacterial protein meal. Inclusion levels of 12 percent for weaned piglets have resulted in increased average daily gain (up to 33%) and average daily feed intake (15%) 11. In growing pigs, inclusion levels of up to 15 percent match the nitrogen retention rate seen in cereal- and soybean meal-based diets, and the overall protein and energy metabolism in growing pigs is not affected when up to 15 percent bacterial protein meal is incorporated in the feed3. For broilers, up to 12 percent bacterial protein meal in the feed improves feed efficiency by six percent, while mink and dogs can be Figure 3: The bacterial protein meal, Uniprotein®, compared with premium fishmeal and soybean meal. fed with an inclusion level of eight percent and 12 percent, respectively, and have an equally high digestibility rate, average daily gain and growth response compared to a fishmeal control diet5,6. Despite the positive effects on the animals’ health and improved digestion, Uniprotein® is also a very sustainable protein nutrient source because of its ability to grow rapidly on substrates with minimum dependence on soil, water and climate1. Unibio’s game-changing green technology thus really makes a difference for the future and is the most optimal production form in terms of environmental and sustainable aspects with respect to Figure 4: Illustration of the environmentally friendly production of the bacterial protein meal Uniprotein®. land use and water footprint (Figure

gastrointestinal differentiation in the digestive tract of the fish8,9. Thus, Uniprotein® may trigger the immune response in the gastrointestinal tract of the fish and thereby prevent soybeaninduced enteritis7. It is not only in fish that bacterial protein meal has been shown to have some positive effects on the immune response. In shrimp, inclusion levels of up to 100 percent bacterial protein
