Hen Housing

Jul 21, 2023

Egg laying hens are housed a variety of ways in Canada. Every housing system is designed to provide a clean environment, fresh food and water, and protection from predators. Additionally, every indoor housing system offers consistent temperature, humidity, lighting and air quality. Egg farmers are continuously seeking to improve the care and well-being of their hens.

Each hen housing system has its own unique set of benefits and challenges. Regardless of the housing system utilized, it is ultimately the farmer’s experience and expertise that enables the associated benefits to be realized and the challenges to be overcome. The farmer, not the housing system, is responsible for achieving Canada’s world-class standards for animal care, food quality and safety.

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.
