In the heart of China, researchers are unlocking new ways to bolster the health and productivity of broiler chickens, with implications that could ripple through the global poultry industry and beyond. At the forefront of this innovation is Mengjun Wu, a researcher from the Hubei Key Laboratory of Animal Nutrition and Feed Science at Wuhan Polytechnic University. Wu’s latest study, published in the journal ‘Poultry Science’ (translated from Chinese), delves into the potential of phloretin, a natural compound, to combat necrotic enteritis, a costly and prevalent disease in broilers.
Necrotic enteritis, caused by the bacterium Clostridium perfringens, can wreak havoc on chicken intestines, leading to reduced growth rates, increased feed conversion ratios, and even mortality. The economic impact is substantial, with estimates suggesting that the disease costs the global poultry industry billions of dollars annually. But Wu and his team may have found a promising solution in phloretin, a compound found in the bark of apple trees and the roots of pear trees.
The researchers fed broiler chickens a diet supplemented with phloretin and then challenged them with both coccidia and Clostridium perfringens to induce necrotic enteritis. The results were striking. “We observed significant improvements in growth performance, particularly in the early stages,” Wu explains. “The phloretin-supplemented group showed enhanced antioxidant capacity and improved intestinal morphology.”
But the benefits didn’t stop at improved growth rates. Phloretin also bolstered the chickens’ immune response, increasing the levels of secretory IgA in the ileum and modulating the expression of certain cytokines. Moreover, the compound helped to restore the balance of intestinal microbiota, which had been disrupted by the necrotic enteritis challenge. This led to increased levels of short-chain fatty acids, such as acetic and butyric acid, which are crucial for intestinal health.
One of the most intriguing findings was the role of phloretin in promoting the production of plant secondary metabolites. These compounds, which include things like flavonoids and phenolic acids, have been shown to have a range of health benefits. In this study, phloretin treatment led to increased levels of phloretin 2′-o-glucuronide, a metabolite with known anti-inflammatory and antioxidant properties.
So, what does this mean for the future of the poultry industry? If these findings can be replicated on a larger scale, phloretin could become a valuable tool in the fight against necrotic enteritis. By improving growth performance and reducing the need for antibiotics, it could help to boost productivity and profitability for poultry farmers. Moreover, the insights gained from this study could pave the way for further research into the use of natural compounds in animal nutrition.
But the potential applications don’t stop at the poultry industry. The findings could also have implications for other sectors, including human health. As our understanding of the gut microbiome continues to grow, so too does our appreciation for the role of natural compounds in promoting health and wellbeing. This study, published in ‘Poultry Science’, is a testament to the power of interdisciplinary research and the potential of natural compounds to revolutionize the way we think about health and nutrition. As Wu puts it, “This is just the beginning. There’s so much more to explore.”
