332. Association of Glucose Metabolism with Residual Feed Intake in Beef Bulls.

In the beef industry, improving feed efficiency provides economic and environmental benefits. Residual feed intake (RFI) has been widely used to identify animals that maintain performance with reduced feed intake, yet the biological mechanisms underlying RFI variation remain unclear. The objective of this experiment...

Supplementation of a Bacillus-based DFM mixture on growth performance, methane emissions, microbiome, and metabolome in backgrounding beef heifers.

Direct-fed microbials (DFM) have been used to improve livestock production efficiency and reduce environmental impact. Spore-forming bacteria such as Bacillus spp. present handling and processing advantages for use as a DFM; however, more information is needed about their effects in beef cattle. The objective of this s...

PS3-17. Sexual Dimorphism of Supplementation with Rumen-protected Methionine in Early Gestation in Beef Cattle Systems – Postweaning Effects.

Maternal supplementation with rumen-protected methionine (RPM) may improve embryo development and calf performance when fed during early gestation. Previous data from our group indicated male calves from RPM-supplemented dams during the periconceptional period higher birthweight compared to control calves, with no di...
