The Effect of Mannan Extracts from Palm Kernel Meal on Pathology and Histopathology of Intestinal and Liver of Broiler Chickens Infected with Salmonella Typhimurium
Introduction
Salmonella typhimurium is a significant enteric pathogen that frequently attacks poultry, posing a substantial threat to the livestock and human health industries due to its zoonotic nature. In an effort to overcome this issue, researchers have begun to focus on the use of natural ingredients, one of which is the Oligosaccharide Mannan originating from palm kernel meal. This study aims to explore the influence of mannan extract on the relative weight of the liver and intestinal organs, as well as changes in pathology and histopathology in broiler chickens infected with Salmonella typhimurium.
Background
Salmonella typhimurium is a major concern in the poultry industry, causing significant economic losses and posing a risk to human health. The use of antibiotics in animal feed has been a common practice to prevent and control Salmonella infections. However, the overuse and misuse of antibiotics have led to the development of antibiotic-resistant bacteria, making it essential to explore alternative solutions. Natural ingredients, such as mannan extract, have gained attention as potential alternatives to antibiotics in animal feed.
Methodology
This study used 96 Cobb strain broiler chickens, one day old, as experimental subjects. On the third day, all chickens were infected orally with 10^5 CFU Salmonella typhimurium to induce infection. Mannan extract was administered at several levels of concentration, namely 0%, 0.1%, 0.2%, 0.3%, and 0.4%, and antibiotics as control. Measurements were carried out to analyze the relative weight of the intestine and liver, as well as observation of pathological and histopathological changes.
Results
The results showed that there was no significant difference (p> 0.05) between the administration of mannan extracts to the relative weight of the intestine and liver. Further observations in aspects of pathology and histopathology also do not show significant differences (p> 0.05). This indicates that the administration of mannan extracts on the concentration tested does not negatively affect the health of the intestinal organs and liver of broiler chickens.
Discussion
The findings of this study suggest that mannan extract originating from palm kernel meal is safe for use in livestock, especially in broiler chickens infected with Salmonella typhimurium. The results indicate that mannan extract can be considered as a good alternative to replace antibiotics, which is highly relevant in the context of improving livestock health and mitigating the problem of antibiotic resistance that is increasingly widespread.
Conclusion
This study opens opportunities for further development regarding the use of natural ingredients in animal feed. This will not only have a positive impact on livestock health but also has the potential to reduce the risk of zoonotic infections that can move to humans. With this approach, it is expected that the livestock industry can switch to more sustainable and environmentally friendly practices.
Implications
The use of mannan extract as an alternative to antibiotics in animal feed has several implications. Firstly, it can help to reduce the risk of antibiotic resistance, which is a growing concern in the livestock industry. Secondly, it can promote sustainable and environmentally friendly practices in the livestock industry. Finally, it can improve the health and well-being of broiler chickens, reducing the risk of zoonotic infections that can move to humans.
Future Directions
This study provides a foundation for further research on the use of natural ingredients in animal feed. Future studies can explore the effects of mannan extract on other aspects of broiler chicken health, such as immune function and gut health. Additionally, studies can investigate the use of mannan extract in combination with other natural ingredients to enhance its effectiveness.
Limitations
This study has several limitations. Firstly, the sample size was relatively small, and further studies with larger sample sizes are needed to confirm the findings. Secondly, the study only investigated the effects of mannan extract on broiler chickens infected with Salmonella typhimurium, and further studies are needed to investigate its effects on other pathogens. Finally, the study only investigated the effects of mannan extract on the relative weight of the intestine and liver, and further studies are needed to investigate its effects on other aspects of broiler chicken health.
Recommendations
Based on the findings of this study, the following recommendations are made:
Further research is needed to confirm the findings of this study and to investigate the effects of mannan extract on other aspects of broiler chicken health.
The use of mannan extract as an alternative to antibiotics in animal feed should be explored further, and its effects on other pathogens should be investigated.
The use of mannan extract in combination with other natural ingredients should be investigated to enhance its effectiveness.
The livestock industry should consider switching to more sustainable and environmentally friendly practices, such as the use of natural ingredients in animal feed.
Conclusion
In conclusion, this study provides evidence that mannan extract originating from palm kernel meal is safe for use in livestock, especially in broiler chickens infected with Salmonella typhimurium. The findings of this study suggest that mannan extract can be considered as a good alternative to replace antibiotics, which is highly relevant in the context of improving livestock health and mitigating the problem of antibiotic resistance that is increasingly widespread.Frequently Asked Questions (FAQs) about the Effect of Mannan Extracts from Palm Kernel Meal on Pathology and Histopathology of Intestinal and Liver of Broiler Chickens Infected with Salmonella Typhimurium
