K-State Releases New Record-Keeping APP For Cattle

Sep 21, 2023

Kansas State University agricultural economics and veterinary medicine staff have developed a record-keeping app for cattle producers that now is available for iPhones and Android devices. The CalfDex app is free to download and was designed for use in the field, even where cell phone service is not available.

According to K-State livestock economist Ted Schroeder, who helped develop the app, CalfDex enables producers to maintain efficient and accurate calving, weaning and treatment records, which helps mitigate the risk of data loss or misplacement that can happen with paper records. It consists of five respective tabs for which users can choose to enter data, including “Calving,” “Processing/vaccination,” “Treatment,” “Weaning” and “Postweaning."

Video: Validating Net Energy in Commercial Swine Systems - Gustavo Lima

In this episode of The Swine Nutrition Blackbelt Podcast, Gustavo Lima, PhD candidate at Iowa State University, explains how soybean meal net energy is evaluated using growth assays and calorimetry. He discusses caloric efficiency, validation under commercial conditions, and differences between controlled and real-world environments. Gustavo also highlights practical implications for diet formulation and ingredient valuation. Listen now on all major platforms!

“Indirect calorimetry provides a precise estimation of ingredient energy, yet validation under production conditions remains essential for accurate application in real systems.”

Meet the guest: Gustavo Lima / gustavo-lima-a9867127 is a PhD candidate in Animal Science at Iowa State University, specializing in swine nutrition, ingredient evaluation, and energy metabolism. With over 15 years of experience across Latin America, his work focuses on soybean meal utilization, caloric efficiency, and applied research for commercial production systems.
