This technical podcast primarily discuss dry matter (DM) in livestock nutrition, defining it as the feed component remaining after water removal, encompassing all nutrients.

They explain that fiber, specifically Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF), is a subset of DM, representing indigestible structural carbohydrates crucial for rumen function.

The discussion highlights that low-quality dry fodder, like rice straw, is high in fiber and low in protein, leading to reduced feed intake, impaired digestibility, and negative health outcomes for ruminants.

Conversely, the sources present hydroponic fodder as a highly nutritious feed, superior in protein and energy, that can be effectively blended with dry roughage to improve milk production, animal health, and reproductive performance, offering a cost-effective and balanced dietary solution.
