<strong>Antibiotic</strong> Applications<br />
●<br />
Antimicrobials used during food production and manufacturing to improve the efficiency <strong>of</strong><br />
the system, and increase the safety and quality <strong>of</strong> the product<br />
▲ <strong>Animal</strong> Husbandry in USA – <strong>Antibiotic</strong>s<br />
♦ Poultry – 8.4 billion broilers and 26<br />
64 million turkeys (2004)<br />
■ 10,000 – 20,000 broilers per house and 5,000 – 10,000 turkeys per group<br />
♦ Swine – 103 million hogs slaughtered for food (2005)<br />
■ >75% <strong>of</strong> swine grown in operations with >5000 head<br />
♦ Beef Cattle – 37 million head slaughtered (2004)<br />
■ Ca. 83% <strong>of</strong> feedlots use ≥1 antibiotic for disease prophylaxis or to increase<br />
feed efficiency<br />
♦ Dairy Cattle – 9.12 million head in milk production (2001)<br />
■ <strong>Antibiotic</strong>s used to treat mastitis<br />
♦ Veal Calves – raised individually in<br />
stalls until 16-18 weeks <strong>of</strong> age<br />
■ <strong>Antibiotic</strong>s used to treat respiratory and gastrointestinal diseases and for<br />
disease prophylaxis<br />
<strong>Antibiotic</strong> uses:<br />
Therapeutic, including subtherapeutic to prevent disease or control pathogens (ca.<br />
95% <strong>of</strong> antibiotic usage)<br />
Non-therapeutic uses: Promote growth rate and feed efficiency
