The Role of Research and Methionine in Brazilian Poultry Production
Brazilian poultry farming has stood out globally, a result of investments in research and the productive organization of the sector. In 2022, Brazil exported 4.822 million tons of chicken meat, making it the second-largest producer in the world, behind only the United States. The southern region of Brazil is responsible for more than 70% of this production (ABPA, 2022).
This success was only possible due to advancements in research on poultry nutrition and genetics. These investigations have led to the development of birds with a better nutrient intake-to-muscle tissue conversion ratio, as well as high-quality cuts like thighs and breasts. However, these improvements have also brought more specific physiological and nutritional demands, requiring ongoing research to better understand these phenomena.
The Role of Nutrients in Poultry Nutrition
Nutrients are not only essential for metabolic functions, but they also play a fundamental role in cellular signaling systems. These systems require sensors or receptors to decode and transmit information, allowing cells to adapt to environmental changes. This can include alterations in gene expression, RNA and protein stability, and protein activity.
One way to understand the integrated action of nutrients in the animal body is through nutrigenomics, which explores the interaction between genes, diet, environmental factors, and gut microorganisms. This area investigates how these interactions affect digestion, absorption, excretion of nutrients, and animal metabolism.
Post-Genomic Sequencing Research in Poultry Nutrition
Since the sequencing of the poultry genome, numerous studies have explored the effects of nutrition on gene expression. Among the essential nutrients, methionine has garnered attention for its role in protein synthesis and as an antioxidant.
The Role of Research and Methionine in Brazilian Poultry Production
Investments in research, combined with the productive organization of the poultry sector, have positioned Brazil as a global leader in poultry production and a key player in consumer markets. In 2022, the country exported 4.822 million tons of chicken meat, making it the second-largest producer of chicken globally, trailing only the U.S. The southern states of Brazil are responsible for over 70% of this production (ABPA, 2022).
This success would not have been possible without research into poultry nutri...
