Probiotic spray method improves hatchability, health of chicks

Mary Anne Amalaradjou, associate professor of animal science in the College of Agriculture, Health and Natural Resources, patented a method of spraying eggs with probiotics shown to improve embryonic development and post-hatch growth of chicks raised for broiler production. This method improves chick health without relying on antibiotics, which are increasingly banned due to the rise of antibiotic-resistant bacteria – a threat to human and animal health. This is especially relevant as there has recently been a drop in hatchability, defined as how many chicks successfully hatch from the group of eggs put into an incubator. Scientists do not yet know what could be responsible for this drop.
