Beta-Adrenergic Agonists, Dietary Protein, and Rumen Bacterial Community Interactions in Beef Cattle: A Review

Abstract

Improving beef production efficiency, sustainability, and food security is crucial for meeting the growing global demand for beef while minimizing environmental impact, conserving resources, ensuring economic viability, and promoting animal welfare. Beta-adrenergic agonists and dietary protein have been critical factors in beef cattle production. Beta-agonists enhance growth, improve feed efficiency, and influence carcass composition, while dietary protein provides the necessary nutrients for muscle development and overall health. A balanced approach to their use and incorporation into cattle diets can lead to more efficient and sustainable beef production. However, microbiome technologies play an increasingly important role in beef cattle production, particularly by optimizing rumen fermentation, enhancing nutrient utilization, supporting gut health, and enhancing feed efficiency. Therefore, optimizing rumen fermentation, diet, and growth-promoting technologies has the potential to increase energy capture and improve performance. This review addresses the interactions among beta-adrenergic agonists, protein level and source, and the ruminal microbiome. By adopting innovative technologies, sustainable practices, and responsible management strategies, the beef industry can contribute to a more secure and sustainable food future. Continued research and development in this field can lead to innovative solutions that benefit both producers and the environment.

Gamma Radiation Effects on Dwarf Napier Grass Quality in Acidic Soil: A Study of Minerals and Rumen Fluids

“…These findings indicate that a higher concentration of nitrogen in dwarf napier grass can elevate the levels of ammonia (NH 3 ) and volatile fatty acids (VFA) in the fluid of the rumen. Nitrogen is a crucial nutrient necessary for the growth and development of rumen bacteria (Pfau et al, 2023). The bacteria in the rumen contribute to the production of NH 3 and VFA (Daning et al, 2022), which serve as significant sources of energy and nutrition for the growth and development of ruminant (Guo et al, 2020).…”
