Abstract
In 2023, Louisiana experienced one of the hottest and driest summers on record, leading to substantial declines in the quality and availability of grazing and hay pastures. This situation pushed many cattle producers to turn to rice straw as an alternative forage. This study aimed to evaluate the nutritional value of rice straw, collecting 52 samples from various varieties across the state and analyzing them for dry matter, protein, fiber, minerals, and energy. These results were compared with 13 warm-season grass forage samples harvested within the same two-month period in July and August. The analysis revealed that rice straw had lower crude protein content and relative forage quality than traditional grass forages, underscoring the need for supplementation when used as a primary feed source. This study offers critical insights for producers considering rice straw for winter feeding, emphasizing the importance of adequate supplementation to meet nutritional needs of cattle.
