Bridging the Knowledge Gap on Human Mammary Insufficiency Lipid Metabolism and Vitamin D as Predictors of Breastfeeding Outcomes
The Problem: Mothers in resource-poor environments have higher rates of both infection and nutritional deficiencies. This may lead to chronic inflammation and low milk production, leading to numerous maternal and infant health issues.
The Idea: Supplement mothers with Vitamin D breast milk to improve maternal and infant health.
The Risk: The Vitamin D supplementation could fail to make a significant impact on breastfeeding.

Investigating the association between A and D status and reproductive performance in sows
Vitamin A and D are important regulators of reproduction yet current swine survival and mortality rates suggest nutrition is inadequate. Our aim is to understand the nutritional vitamin status in swine breeding herds and enhance diagnostic and production outcomes. Results will enhance our understanding of vitamin status and reproductive performance, maximizing the impact of vitamin nutrition, enhancing producer efficiency, profits, and sow and piglet wellbeing.
