| Antibiotic alternatives "no effect" on broiler growth |
 |
| Chinese study says common prebiotics and herbs have no effect on broiler growth rates |
A Chinese study has concluded that common prebiotics and herbs used instead of antibiotic growth promoters have no effect on broiler growth rates, but can strengthen immunity.
The study looked at the effects of the prebiotic group fructooligasccharides, galactoligosaccharides and mannan oligosaccharides (MOS), and the Chinese herbal medicines Ligustrum lucidum and Schisandra chinensis....

Imugene achieves proof of concept in flu vaccine trials |
 |
| Lamb: Positive result |
Australia's Imugene has reported positive preliminary results from efficacy trials of its avian influenza vaccine candidates for poultry.
The lead broiler vaccine has now achieved proof of concept and will now enter the next phase of development.
In tests conducted by contract research firm Benchmark Biolabs, the vaccine protected seven out of 11 vaccinated birds challenged with very high dose of a highly pathogenic Asian strain of the H5N1 avian influenza virus....

| Antimicrobial resistance in Scandinavia after ban of antimicrobial growth promoters |
| The banned use of antimicrobial growth promoters resulted in a considerably decreased use of antimicrobials in food animal production in Sweden (65%), Denmark (47%), Norway (40%) and Finland (27%). The current prevalence of antimicrobial resistance in animal bacterial populations is also considerably lower than in some other countries in the EU. |

| Genetics of antimicrobial resistance |
| The increasing prevalence of antimicrobial resistant bacterial pathogens has severe implications for the future treatment and prevention of infectious diseases in both animals and human. |
|
| Genetic linkage and horizontal gene transfer, the roots of the antibiotic multi-resistance problem |
| This review on the problems in terms of treatment with or resistance to a single antibiotic at a time assumes that dissemination of the resistance gene was affected by simple vertical inheritance. |

| Reduced use of antibiotic growth promoters in diets fed to weanling pigs: Dietary tools, Part 1 |
| Antibiotics improve health and productive performance of pigs. There is increasing evidence that other dietary ingredients may provide similar, but probably not identical, benefits.

| Reduced use of antibiotic growth promoters in diets fed to weanling pigs: Dietary tools, Part 2 |
| There is strong evidence that diets formulated with cereal grains other than corn, with a low concentration of crude protein and with the use of direct-fed microbials, will improve intestinal health and performance of weanling pigs. |

| The Take Care Program and responsible use of antibiotics |
| While the contribution of antimicrobial use in pork production to resistant bacteria in human health is uncertain, pork producers have the responsibility to deliver safe and wholesome pork to consumers. |
