1. Disease Detection and Prevention in Poultry
Early Detection of Illnesses: Al- powered systems can analyze patterns in poultry health data (such as temperature, behavior, and feed intake) to identify early signs of diseases. Machine learning models can process vast amounts of data from sensors, cameras, and even behavioral observations to detect unusual patterns that might indicate disease outbreaks, enabling quicker intervention.
Al-powered systems play a crucial role in the early detection of diseases in poultry by analyzing a wide array of data from multiple sources. These systems can monitor physiological indicators such as body temperature, feed intake, water consumption, and movement patterns, as well as behavioral changes like lethargy or altered feeding behavior. Machine learning models process these data streams in real-time, flagging deviations from typical patterns that might indicate the onset of a disease. For instance, temperature fluctuations or changes in activity levels could signal the presence of an infection, even before visible symptoms appear. Additionally, Al can analyze data from sensors, cameras, and even audio recordings to detect coughing or unusual vocalizations, which may indicate respiratory issues. This real-time monitoring enables quicker identification of health concerns, allowing for timely intervention and reducing the spread of infectious diseases within poultry populations.
Predictive Analytics: Al can predict the likelihood of disease outbreaks based on environmental, genetic, and health data, allowing for proactive measures like vaccination and biosecurity protocols. Al-based predictive models can further enhance disease prevention in poultry farming by forecasting the likelihood of outbreaks before they happen.
By analyzing historical data on disease incidence, weather conditions, farm management practices, and genetic profiles of poultry, Al can identify patterns and correlations that suggest an elevated risk of specific diseases. For example, certain environmental factors like temperature, humidity, or overcrowding may increase the likelihood of diseases such as avian influenza or Newcastle disease. Genetic data, on the other hand, can indicate a higher susceptibility to particular pathogens in certain poultry breeds. Predictive analytics can also factor in ongoing health trends, vaccination histories, and regional outbreaks, creating a comprehensive risk profile for a farm or poultry population. With this information, farm managers can take proactive measures, such as adjusting environmental conditions, implementing targeted vaccination campaigns, and reinforcing biosecurity measures to prevent potential outbreaks. These predictive capabilities help to not only reduce disease incidence but also lower the costs associated with large-scale outbreaks, ensuring better overall poultry health and welfare.

Feeding chickens a low-protein diet has led to a notable reduction in the environmental impact of poultry farming. However, this diet negatively impacts muscle mass, consequently affecting meat production. In this study, researchers explore the effects of supplementing a low-protein diet with amino acids, the building blocks of proteins. Results reveal the mechanism through which amino acid supplementation offsets the negative effects of a low- protein diet in chickens.
Chicken is one of the most widely consumed meats worldwide and
global food demands has steadily been growing over time, making poultry farming a thriving industry. However, raising chickens for meat has also contributed to global warming, mainly as a result of increased nitrogen excretion and ammonia emissions. Feeding broilers a low- protein diet can alleviate the environmental impact of chicken meat production since it has the potential to reduce nitrogen emissions.
The downside of using a low- protein diet is that it negatively affects the growth performance of broiler chicks, measured by factors such as weight gain and feed conversion ratio, which is the efficiency with which the chickens convert their feed intake into mass. Studies have shown that to ensure that there is no loss of growth performance, low-protein diets can be supplemented with amino acids, which are the building blocks of proteins. However, precisely how amino acid supplementation helps alleviate the negative effects of a low-protein diet is not clearly understood.
Underlying mechanisms
Now, in a study published in The Journal of Poultry Science, Dr Kazuhisa Honda, editor-in-chief, Japan Poultry Science Association, and Professor, Graduate School of Agricultural Science at Kobe University, examined the mechanisms underlying the impact of amino acid supplementation on broiler chickens that were fed a low- protein diet. Explaining further about their endeavour, Honda says: "Throughout the world, a protein crisis is a serious problem in the animal industry. Secondly, global warming as a result of meat production has added to these concerns worldwide. By applying our results and utilising low- protein feed, we hope to reduce N2O emissions in the environment.”
Effects of Amino acids-supplemented low-protein diet in broiler chicks
First, the researchers fed 3 groups of broiler chicks with different types of food: a standard recommended diet, a low-protein diet with 15% reduced protein content, and a low-protein diet supplemented with amino acids. To see how these diets affected growth performance, they monitored parameters such as feed intake and weight gain until the chicks were 35 days old.
For chicks fed a low-protein diet, there was a significant decrease in body weight as well as breast and leg muscle weight compared to those fed a standard diet. However, none of these effects were observed in chicks fed a low-protein diet supplemented with amino acids, indicating that amino acid supplementation was able to mitigate the negative effects of a low-protein diet. The poultry industry is faced with issues such as a protein crisis and global warming. Researchers from the Japan Poultry Science Association and Kobe University have now found that in broiler chicks, supplementation with essential amino acids alleviated the negative effects of a low-protein diet on growth performance.

Gene expression
To explore these findings further, they looked closely at various genes involved in muscle synthesis and degradation. Real-time polymerase chain reaction analyses - a technique that detects the amplification of DNA molecules in real time - were used to examine the extent to which these genes were 'expressed' in different muscles. Surprisingly, the results showed that the impact of the low-protein diet was different in the breast muscle (pectoralis major) and the leg muscle (biceps femoris).
The pectoralis major of chicks on a low- protein diet was found to have an increased expression of the gene LC3B (microtubule-associated protein 1 light chain 3 isoform B). However, in the biceps femoris muscle of the thighs, increased expression of the genes atrogin-1, MuRF-1 (muscle RING-finger protein-1), and MyoD (myoblast determination protein 1) was observed. While there were distinct gene expression patterns for different muscle groups, all the identified genes are involved in protein degradation, suggesting that a low- protein diet induces proteolysis in muscles.
Moreover, no differences were found in gene expression between chicks fed a standard diet and those fed the amino acid-supplemented low-protein diet. The results not only provide an explanation for the reduced growth performance with the low-protein diet, but also indicate that amino acid supplementation alleviates these effects differently in different muscle groups.
Major implications
Findings from the study have major implications for the poultry industry. As Honda explains, "Our results will contribute to the development of low- protein feed for broiler chickens, which is still a major challenge in developing countries."
By doing so, it opens doors for the increased use of low-protein feed, which means lower animal production costs in the future. These findings also address important concerns around global warming and the environmental impacts of the poultry industry. The researchers are hopeful that using a low-protein feed with amino acid supplementation can reduce nitrogen emissions to the environment, promising a more sustainable and eco-friendly future for meat production.
