Effects of beta glucans in poultry health and nutrition

The poultry production industry has seen astonishing improvements over the past several decades as evidenced by increased growth rates and improved feed conversion efficiency. We can now produce bigger and faster growing birds with far less feed than imagined even 20 years ago. These improvements can be attributed to a combination of genetics, nutrition, farm management and disease management. Genetics ultimately limit the maximum potential growth performance of the birds, while nutrition, farm management and disease management can each impact how close to the genetic potential the birds can achieve on a given farm. This paper addresses the rapidly evolving field of disease management and the new tools that producers can use to improve the health and thus performance of their animals.
Increasing role of immune modulators in poultry production

Antibiotics and specifically antibiotic growth promoters (antibiotics used prophylactically for disease prevention and modest growth enhancement) have made a significant contribution to some of the performance gains in recent decades. While the exact mode of action of these drugs is still not completely understood, the potential impacts on promoting antibiotic resistance is becoming more apparent and thus their usage is being phased out across many
