Unlocking the nutritional benefits of dietary fiber in sow feed: a short review

Vetriselvi Sampath, Joon Pyo Oh, In Ho Kim

J Anim Sci Technol 2026;68(2):389-398.
https://doi.org/10.5187/jast.2025.e9

Dietary fiber is a critical nutrient in sow diet and was addressed in several studies in the past decades. It plays a key role in improving digestive health, supporting metabolic functions, and enhancing the overall well-being of sows. Fiber, a plant-based feed ingredient is classified into soluble and insoluble fibers. Soluble fibers, such as pectin, dissolve in water and can form gels, influencing the fermentation process in the gut. Insoluble fibers, like cellulose, do not dissolve in water and contribute to the bulk of fecal matter, promoti...

https://doi.org/10.5187/jast.2500296

Time is an intangible yet important element in food production systems. It is often used as one of the bases for technology and production efficiency, with shorter production durations being favored. Meat is a staple source of protein for the human diet; therefore, efforts to improve and optimize production efficiency are always warranted. Growth promoters in traditional meat production are additives used to improve the performance and productivity of livestock animals while the enhancement of proliferation, differentiation, and maintenance cap...

Antral follicle count (AFC) is considered a useful non-invasive method for providing valuable insights into a female’s ovarian reserve. However, the influence of AFC and corpora lutea (CL) at the time of exogenous hormonal trigger (synchronization) on ovarian response to stimulation and fertility in goats remains unclear. This research aims to explore the impacts of different AFC and CL presence at the onset of hormonal synchronization (on Day 0) for fixed-time artificial insemination (fixed-time AI) on response to hormonal stimulation and fe...
