To make this possible, our science-based solutions leverage the beneficial effects of intestinal health management and immune support. Immune modulation plays a vital role in disease prevention and improved health; it helps animals cope better with disease, stress, *and* vaccination. That is why at Kemin we have found the need for innovation in this area to ensure a uniform and safe immune support solution that improves overall animal health. > Together with John Hayden, Pig Veterinarian, and Chris Fogden, Pig Farmer, we evaluated our unique Beta-Glucan product, AletaTM in challenging field conditions. Aleta is a unique Beta-Glucan product derived from an algae, which is used for immune support and modulation to improve general health of the animals. Aleta contains a Beta-(1,3)-Glucan.The objective of this particular study was to assess the impact of Aleta on the resilience and resistance of an outdoor breeding pig herd to PRRS infection, circulation and shedding. ## **Healthy pigs with a minimum amount of antibiotics** “It is always our goal to focus on healthy, productive pigs using a minimum amount of antibiotics”, explains John Hayden. He continues: “however, we had a lot of issues to control a PRRS infection in a, outdoor breeding pig herd, resulting in a 20% pre-weaning mortality. We started investigating Aleta as we saw that the immune system of the herd was under pressure. Interestingly, the pre-weaning mortality and the performance of the pigs came under control quicker.”     “We have been having this long-term health challenge, impacting the weaning quality and weight. We looked at products to help us with vaccine efficiency and tried Aleta. After my experience, I would recommend everybody to look into these. We have only been using it for some time and I am very happy with how they are looking”, states Pig Farmer Chris Fogden. Interested to hear his entire story?
