The Role of Yeast in the Health and Growth of Ruminant Animals
In the livestock industry, yeast has been a long-standing and popular raw material, especially for ruminant animals such as dairy cattle and beef cattle. Farmers often incorporate yeast into their feed through fermentation with raw materials like fermented cassava, fermented corn, or food industry by-products. This practice aims to improve feed quality, enhance digestibility, and promote overall animal health.
What is Yeast?
Yeast is a eukaryotic fungus (Eukaryotic fungi) consisting of various species. It reproduces mainly through budding or fission. Yeast cells are approximately 510 micrometers in diameter.
The most commonly used species in the animal feed industry is Saccharomyces cerevisiae because it grows rapidly and has high nutritional value.
Nutritional Value of Saccharomyces cerevisiae
Several types of yeast are used in the industry, including:
Each type has specific characteristics in terms of nutritional value and production cost. The most common strain used for ruminants is Saccharomyces cerevisiae, which can enhance beneficial microbes in the rumen and help balance digestion.
Benefits of Yeast for Ruminant Animals
Traditionally, yeast was directly fermented with feed materials. Nowadays, farmers are increasingly focusing on safety and precise microbial supplementation by using products in pre-mixed or probiotic forms, which allow better control over quantity and quality.
BioticMax A SAS Product
SAS has developed BioticMax for Ruminants, a high-concentration probiotic containing up to 10¹ CFU/kg, comprising Bacillus spp. and supplemented with Saccharomyces cerevisiae strain yeast. This product is designed to support digestion, bolster immunity, and increase meat and milk production, enabling farmers to raise animals more efficiently and sustainably.

The most commonly used species in the animal feed industry is Saccharomyces cerevisiae because it grows rapidly and has high nutritional value.
Nutritional Value of Saccharomyces cerevisiae
- Protein: up to 4750% of cell weight, containing essential amino acids, particularly lysine at about 611%
- Carbohydrates: approximately 3035%, mainly glycogen, glucans, and mannan
- Vitamins and minerals: such as B vitamins, which are essential for the animal's metabolic processes
Several types of yeast are used in the industry, including:
- Primary dried yeast
- Active dried yeast
- Brewers dried yeast
- Distillers dried yeast (from grains or molasses)
- Torula yeast
- Yeast culture, etc.
Each type has specific characteristics in terms of nutritional value and production cost. The most common strain used for ruminants is Saccharomyces cerevisiae, which can enhance beneficial microbes in the rumen and help balance digestion.
Benefits of Yeast for Ruminant Animals
- Enhance digestion improves carbohydrate utilization and digestion efficiency
- Stimulate feed intake promotes faster weight gain
- Increase beneficial microbial populations in the rumen such as protozoa that help break down starch more efficiently
- Reduce risks from stomach acidity help maintain pH balance
- Improve productivity in terms of meat quality and milk yield

In today’s world, mental health disorders are increasingly prevalent, especially depression. According to data from the Department of Mental Health, over 1.5 million individuals aged 15 and above suffer from depression. This condition arises from an imbalance in neurotransmitters, specifically serotonin and norepinephrine, which are crucial for transmitting signals between nerve cells. Other contributing factors include emotions, feelings, thoughts, and perspectives.
Depression is broadly categorized into two types:
1.Unipolar Depression: The individual experiences only depressive episodes.
2.Bipolar Disorder: The individual experiences extreme mood swings, including depressive episodes and periods of elevated mood.

Heartburn, sour burps, and acid reflux are clear signs of **Gastro-Esophageal Reflux Disease (GERD)**, commonly known as acid reflux disease. GERD has become one of the most prevalent conditions globally, especially in Western countries, where the incidence rate is relatively high, averaging around 50-60%. In Thailand, working-age individuals are increasingly experiencing GERD, and the trend continues to rise. What exactly causes this condition, and are there effective treatments available?

In the year 2023, hypertension ranked as the leading disease among Thai people using the Universal Coverage Scheme for treatment. Surveys also found that among Thais aged 15 and older, the prevalence of this condition is as high as 25.4%, with an increasing trend with age.
Although many people can live their daily lives normally, the danger of this disease is that it often shows no symptoms in the early stages. It is therefore called a "silent threat" or "silent killer," gradually damaging health over time.
