What about gut?
In our latest dossier, experts from science and practice present the latest insights on intestinal health in monogastric animals. Discover more in Dr. Leon Broom’s article (Chief Scientific officer, Gut health consultancy) about the global trends in ABF production in poultry and swine.
Whether “antibiotic-free”, “no antibiotics ever” or “raised without antibiotics” – the efforts of legislators and manufacturers to reduce the use of antibiotics in animal husbandry are becoming increasingly visible to us consumers. No wonder, after all, there are clear concerns about the use of antibiotics in animal production – especially in view of the increasing risk of antimicrobial resistance.
Current estimates suggest that about half of US broiler production is raised without antibiotics, and this figure is expected to continue rising.
Whereas until 2006 it was common practice to use antibiotics in subtherapeutic doses in livestock farming to realize the maximum genetic potential, this practice is now banned in the EU. Similar legislation has also been introduced in other countries, including the USA (Food and Drug Administration, 2015). Whilst there remains some debate about the mode of action of AGP (Broom, 2017), limiting their use is associated with increased intestinal challenges, suboptimal performance and greater costs (Gaucher et al., 2015).
Dr. Leon Broom says...
“ABF production is particularly associated with increased incidences and/or severity of intestinal disorders. In poultry, coccidiosis (caused by a species of the Eimeria parasite) and necrotic enteritis (NE) (caused by pathogenic strains of Clostridium perfringens) have become more prominent diseases in ABF production”
According to Smith (2018),
NE was not considered a significant disease for poultry prior to the AGP ban in the EU in 2006, but now ranks amongst most important diseases globally.
But what measures can help farmers to overcome these challenges?
As a young girl, I dreamed of exploring the deepest jungles. I have always been fascinated by the unknown, the diversity and beauty of nature. Nevertheless, I did not explore the jungle – I studied the rumen of cows at university. After all, it’s also mysterious and varied – it just smells a little bit more austere.
