Methods
Slaughtering of Sheep and Tissue Evaluation
The field of sheep slaughter practices has witnessed notable developments in recent years, including the method based on electrical stunning and exsanguination. In this context, the sheep were weighed in the morning after fasting, and then the slaughter process was carried out using captive bolt stunning and exsanguination in accordance with ethical and medical standards. These methods are essential to ensure animal welfare and maintain health standards. To evaluate the physiological and histological effects of this procedure, samples of vital tissues such as the small intestine, liver, and stomach wall were taken. These tissue samples were later cleaned and preserved in 10% formalin for morphological structure analysis. Hematoxylin-eosin staining was used to determine the morphology of the stomach, liver, and intestine areas. These steps are part of scientific research procedures to ensure the health and safety of sheep during slaughter operations.
Immunohistochemical Techniques and Analysis of Inflammatory Factors
Immunohistochemical techniques are among the most important methods used to detect inflammatory factors in tissues. In this context, a staining method using streptavidin-peroxidase was applied, where inflammatory factors such as caspase-3, NF-κB, and TNF-α were identified. The results of the staining are estimated based on the pattern of nuclear staining and are classified according to the percentage of positive cells. These criteria help in evaluating the relative presence of inflammatory factors in different tissues, providing valuable insights into the inflammation status in sheep. For example, these inflammatory nodules have been recognized to be abundant in tissues of animals suffering from certain diseases, reflecting the need for further analysis of those tissues to develop effective therapeutic strategies.
Rumen Fermentation Criteria and Their Impact on Sheep Health
The process of fermenting feed in the rumen is one of the most important factors that affect sheep health. After a specific trial, rumen fluids were collected from sheep to obtain accurate information about the rumen fermentation environment. This procedure requires the exclusion of the first 50 ml of fluid to prevent salivary contamination. By analyzing these fluids, several factors such as pH, volatile fatty acid (VFA) ratios, and ammonia levels were measured. The criteria used to determine protein, starch, and cellulose activity are essential for achieving a better understanding of sheep nutritional pathways. For example, analyzing the ratios of different VFAs helps determine the nutritional efficiency of sheep, enabling breeders to adjust their diets to ensure better nutrient utilization.
The Impact of Probiotics on Sheep Performance and Economic Benefits
When studying the impact of complex probiotics on sheep, significant improvements in performance and economic growth were observed. For example, the increase in body weight and the economic benefits arising from the use of probiotics were measured. During a specific period, the weight results of sheep in the groups that received probiotics were much better compared to the control group. This is attributed to the effect of probiotics on improving nutrient metabolism efficiency and enhancing immune response. This issue is particularly important to breeders seeking to achieve higher profits by improving the health and growth of their flocks. Dietary supplements containing probiotics can also help reduce costs as they improve digestion and reduce disease rates.

Microbial diversity is a good indicator of gastrointestinal health, as high diversity indicates a good balance between different bacterial species. This diversity can lead to improved fermentation processes, thereby enhancing digestive efficiency. On the other hand, decreased diversity can lead to potential health issues, making the search for strategies to enhance microbial diversity an ideal idea to improve sheep health.
Effect
The effect of composite probiotics on the microbiome composition in sheep rumen
Recent studies show that the use of composite probiotics can have a significant impact on the microbiome composition in sheep rumen. Sheep were divided into four groups, with results indicating that the two groups receiving probiotics at a rate of 400 grams/ton and 800 grams/ton showed a significant increase in the proportion of Firmicutes bacteria, while the proportion of Bacteroidetes bacteria decreased. This suggests that composite probiotics can significantly modify microbial composition, potentially affecting food metabolism in the digestive system of sheep.
The microbial communities in rumen are formed by several key species, including Prevotella, Ruminococcus, and Butyrivibrio. Prevotella is one of the most abundant bacteria in the rumen; however, we observed a decrease in its proportion in the group that received the probiotics at 400 grams/ton. This decrease may reflect the effect of probiotics on microbial balance and therefore on the overall health of sheep. Changes in the microbiome composition can lead to improved nutrient extraction efficiency and enhanced overall performance of sheep.
Relationships between bacteria and fermentation parameters in rumen
An analysis was conducted to determine the relationship between microorganisms in rumen and fermentation parameters. The results showed significant relationships between certain types of bacteria and fermentation parameters. There was a strong positive correlation between Prevotella and Ruminococcus and some environmental factors such as volatile fatty acids (VFA). For example, Prevotella was associated with insoluble fiber, indicating the bacteria’s role in the digestion and breakdown of fiber in feed.
Ruminococcus also showed a positive correlation with acetic, propionic, and butyric acids, indicating that it plays an important role in the production of volatile fatty acids. Conversely, there was a decrease in the production of some quantities like ADG and NH3-N in the presence of the mentioned bacteria. These dynamics indicate the complex patterns of relationships between microbes and digestive processes, where a healthy microbial balance leads to improved digestive performance.
The effect of composite probiotics on the tissue structure of sheep
A set of histological tests was conducted to analyze the structural effects of probiotics on sheep. The results showed that groups B and C receiving probiotics exhibited better results in improving tissue balance compared to the control group. Liver cells were healthy, with no signs of inflammation or hemorrhage, which is evidence that probiotics improve the general health of the intestines and functional performance.
In a study of the intestinal structure, we found that group B showed a significant increase in the number and length of villi, which may facilitate nutrient absorption. Improving tissue structure may directly affect the animal’s ability to assimilate nutrients, thus enhancing overall performance. Studies have also shown that an increase in the number of villi in the intestines typically occurs when probiotics are mixed with feed, leading to positive effects on animal health.
The effect of probiotics on inflammatory cytokine expression
The impact of probiotics on the expression of inflammatory cytokines in sheep was evaluated. The results showed that the group receiving probiotics exhibited a significant reduction in levels of inflammatory cytokines such as Caspase-3, NF-κB, and TNF-α. These findings suggest that probiotics not only enhance gastrointestinal health but also have anti-inflammatory effects.
These changes in cytokine levels contribute to enhancing the sheep’s ability to resist diseases. Probiotics are capable of modulating the immune response by reducing inflammation markers, helping to protect sheep from environmental stress and diseases. These results highlight the importance of probiotics in enhancing immune performance and maintaining overall animal health.
Enhancing the productive performance of sheep using probiotics
Studies have shown that using composite probiotics enhances the productive performance of sheep.

These results reinforce the importance of integrating probiotics in sheep nutrition to improve performance.
This suggests that…
Researchers have found that improving digestive efficiency through the use of probiotics increases energy and nutrient availability, as evidenced by volatile fatty acid levels in the rumen. These improvements also contribute to increased feed digestion efficiency, leading to weight gain. These results align with previous studies that highlighted the relationship between probiotic use and increased productivity in animals.
Ammonia Concentration and Its Relationship to Microbial Growth
Ammonia is one of the byproducts resulting from protein degradation by microbes in the digestive system. Studies have shown that increased levels of NH3-N can be related to microbial regeneration that leads to protein degradation, causing further ammonia production. This is important because it directly affects the health and growth of animals, as high ammonia levels can negatively impact the overall health of sheep and livestock. Therefore, some research has been conducted to understand how microorganisms like Aspergillus oryzae affect ammonia concentration and other digestion processes. Previous research shows that Aspergillus oryzae has the ability to secrete enzymes such as proteases, amylases, and cellulases, enabling it to increase the efficiency of protein degradation and carbohydrate breakdown in the bodies of animals, thereby enhancing the nutritional and productive performance of sheep, especially in ruminants.
Positive Effects of Probiotics on Sheep Digestion
The introduction of probiotics, such as 400 CPs, on amylase and cellulase activity in the rumen is of great importance. Probiotics enhance the activity of beneficial bacteria in the digestive system, thereby helping to improve the digestion of nutrients. In this study, a significant increase was observed in certain bacterial species in the CP groups, with an increase in the presence of Firmicutes, while the proportion of Bacteroidetes was low. Research has shown that the lower ratio of Bacteroidetes to Firmicutes helps enhance fat storage and weight gain in sheep, explaining how the inclusion of probiotics can affect animal growth. Furthermore, dominant species like Prevotella and Ruminococcus enhance carbohydrate breakdown and fermentation processes, which is essential for improving overall health and weight gain.
The Role of Intestinal Morphology in Improving Digestive Health
The morphological aspects of the intestines, such as villus height and the ratio of villus height to intestinal lumen depth, play a crucial role in enhancing digestive efficiency and absorption. Research has demonstrated that the consumption of specific probiotics can improve these parameters, as seen in the group of sheep consuming CPs, where both villus height and the villus-to-lumen ratio were significantly improved compared to the control group. These improvements represent an increase in absorptive area, which in turn leads to a higher rate of nutrient absorption. In the context of another study, it was found that the addition of compounds like Candida utilis could enhance intestinal villi growth, thereby improving overall gut tissue health. Based on these results, it is encouraging for breeders to adopt strategies that rely on improving gut structure to support the effectiveness of the sheep’s diet.
Immune Response and the Effect of Probiotics
The immune response in animals can be significantly affected by the addition of probiotics to their diet. Research has found that the effects of probiotics extend beyond improving digestion; they also provide immune protection and combat inflammation. For example, a significant reduction in the number of positive cells for TNF-α leakage and Caspase-3 in the liver and rumen of the probiotic groups was observed compared to the control group. This anti-inflammatory effect is primarily due to the ability of probiotics to reduce inflammatory cytokines, thereby reducing cell damage. Considering intracellular signaling, studies indicate a direct relationship between TNF-α and Caspase-3 as part of the inflammatory response, making improvements in these areas essential for the health and productivity of sheep.
Conclusions
Practical Applications of Probiotics in Animal Production
The results derived from these studies suggest that the addition of 800 grams per ton of complex probiotics to the diet of Hoi sheep can yield significant positive outcomes. It has been shown that these additions lead to an increase in daily weight gain, improved feed-to-meat ratio, enhanced immune functions, and inflammation resistance, as well as the improvement of living tissue structure, rumen, and intestines. The results also indicated an increase in villi height and depth of villous glands in the small intestine, which enhances digestive functions. These studies indicate the potential use of complex probiotics as an effective strategy to improve the productivity of ruminants, making it an intriguing option for sheep breeders looking for ways to enhance their animals’ performance in a natural and healthy manner.

The Importance of Stroke and Its Effects
Stroke is considered one of the most common and serious medical conditions worldwide, occurring when blood supply to a part of the brain is interrupted. This interruption causes damage to brain cells, leading to loss of neurological functions. Common symptoms of stroke include weakness, paralysis, difficulty speaking, and blurred vision. This condition can lead to long-term complications such as permanent disability or even death. Strokes can be categorized into two main types: ischemic strokes, which occur due to a blockage of a blood vessel, and hemorrhagic strokes, which occur when blood vessels burst.
Research indicates that risk factors such as high blood pressure, diabetes, smoking, and obesity can increase the likelihood of having a stroke. Therefore, prevention through lifestyle changes, such as following a healthy diet, exercising, and avoiding smoking, is critical. Additionally, awareness of stroke symptoms and the necessity for immediate treatment can save a patient’s life or prevent serious complications. These factors reflect the importance of ongoing research into the prevention and treatment of strokes and gathering information on the contributing factors.
Researchers and Their Studies on Neural Effects

Research reveals the role of the immune response in the development of neurological diseases. This response includes the use of reliable factors that limit inflammation and fight harmful microbes. Studies prompt us to reconsider ways to enhance immunity and develop new strategies to combat neurological diseases. For example, research has focused on the role of microorganisms in the gut and how they can affect brain health. These studies recognize the close relationship between the immune system and brain health.
Genetic Analysis Technology and Its Role in Precise Research
Innovations in genetic analysis technology have provided new tools for researchers to study the effects of genes on human health, including their impact on brain functions. Using techniques like DADA2, scientists can now accurately identify patterns and microbial groups associated with diseases. Genetic analysis can represent an important step towards understanding the genetic factors influencing the incidence of strokes or other neurological diseases.
Moreover, the use of genetic databases like SILVA indicates that genetic research can help clarify genetic diversity among living organisms, suggesting that understanding genetic composition could increase the effectiveness of available treatments. Additionally, these tools help improve gene-based treatment strategies, potentially leading to more personalized treatments for individuals.
The Growing Interest in the Gut Microbiome and Its Health Effects
There has been significant interest in the role that the gut microbiome plays in overall health, including its effects on brain health. The microorganisms living in the gut are considered a vital part of overall body health, and an imbalance among these organisms contributes to the emergence of inflammation and various diseases. Recent studies have shown that elements like probiotics can enhance microbiome health, thereby positively impacting mental health.
The effect of dietary compounds, like fibers and proteins, on shaping the nature of the microbiome has been studied. Some research suggests that fiber consumption modifies microbial composition and enhances the production of short-chain fatty acids, which play a role in promoting neurological health. These acids contribute to reducing inflammation and improving neuronal performance, paving the way for new applications in treating neurological disorders through specific dietary products.
Regulatory Challenges in Neurological Science
Health systems face significant challenges related to dealing with neurological diseases such as strokes. The introduction of new technologies and advancements in treatments poses a challenge to existing health policies, which may be slow to adapt to innovations. There is a critical need to develop flexible systems that support clinical research and permit new applications in a timely manner.
These challenges require collaboration between scientists and regulatory bodies to achieve significant leaps in understanding and treating neurological conditions. There should be considerable interest in sharing information and enriching medical practices with the expertise of researchers in genetics, microbes, and modern technology. Developing support for precise research is critical to accelerating treatments for patient care and improving the quality of life for individuals with complex health conditions.
The Effect of Probiotics on Dairy Cows in the Postpartum Period
The nutrition of dairy cows is one of the essential factors affecting milk production and quality. One research highlighted the effectiveness of using probiotics in managing the nutrition of dairy cows during the postpartum period. Probiotics are a group of microorganisms added to the diet to enhance the overall health of cows. Results indicate that adding probiotics can improve fermentation properties in the rumen, contributing to better feed utilization and increased milk production. On the other hand, studies have shown that probiotics can improve milk composition, increasing the percentage of protein and healthy fats in it. For example, one experiment conducted on a group of dairy cows showed that probiotics led to an increase in milk produced by up to 10% compared to those that did not receive the supplements.

The Impact of Nutritional Supplements on Fermentation in the Rumen
Fermentation of feed in the rumen is a biological process that significantly affects the health of cows and their ability to utilize nutrition. The microbes present in the rumen, such as bacteria and fungi, are responsible for this process. Research suggests that the use of nutritional supplements, including probiotics, can modify the microbial composition of the rumen and improve fermentation efficiency. For example, adding specific bacteria may enhance the rumen’s ability to digest fiber, leading to more efficient production of short-chain fatty acids. It has also been found that the amount of byproducts resulting from fermentation decreased, indicating improved feed utilization efficiency. These changes contribute to producing higher quality milk, benefiting farmers.
The Importance of Nutrients Diversity in the Diet of Cows
When seeking to enhance the health of lactating cows, we cannot overlook the importance of dietary diversity. The cow’s diet needs a balanced mix of nutrients, including proteins, fibers, fats, minerals, and vitamins. Research has shown that when diverse nutrition is appropriately provided, cows are better able to utilize these nutrients, leading to improved health and production performance. For example, increasing fiber intake in the diet enhances rumen health and encourages more effective fermentation, while proteins boost milk production. Therefore, it is crucial for farmers to develop a solid feeding plan that considers all necessary nutrients to ensure animal welfare and the quality of the produced products.
The Rumen’s Response to High-Grain Nutrition
Feeding cows with grain-rich diets can alter the microbial environment of the rumen. Studies have demonstrated that when cows consume large amounts of grains, it leads to increased production of short-chain fatty acids; however, it may also be accompanied by an increase in harmful gas emissions such as methane. Thus, probiotics are used as a balancing agent to help mitigate the effects of high-grain feeding. Additionally, the use of probiotics can contribute to regulating the existing microbes, thereby reducing the risks associated with high-sugar nutrition.
