Rhodiola extract is the root extract of Rhodiola, which is sweet and bitter. The main ingredients are salidroside, tyrosol and losevin, which have the effects of enhancing immune function, protecting cardiovascular and cerebrovascular system, anticancer and antidepressant. Rhodiola extract is a natural extract extracted from Rhodiola crenulata, which is refined, concentrated and dried. It is very soluble in water, methanol, ethanol and ether. It is stable to heat. Rhodiola mainly contains phenylpropanoids and flavonoids. Its unique active chemical constituents are phenylpropyl esters, rosavin (the most active), rosin, rosarin, rhodiolin, salidroside and its aglycone [1], namely p-tyrosol. Only Rhodiola rosea contains rosavin, rosin and rosarin.

The nutrition requirement of turtle and its compound feed
The soft-shelled turtle, commonly known as the Chinese softshell turtle, is a reptile belonging to the family Trionychidae. It is often referred to by various names such as "fish," "yuan fish," or "water fish." This species is native to temperate and subtropical regions of Asia, with over 30 species in its genus. Among them, three are commonly farmed domestically: *Trionyx sinensis*, *T. stejnegeri*, and *T. ferox*. The common name "Chinese sturgeon" is sometimes mistakenly used for this species.
Due to its high nutritional value, medicinal properties, and delicious taste, the soft-shelled turtle has become highly popular in both domestic and international markets. However, the sharp decline in natural populations has led to a growing supply-demand gap, resulting in high prices. As a result, turtle farming has expanded rapidly across China. Two main breeding methods are used: natural breeding and warm water cultivation. Natural breeding requires 4–5 years to reach market size, making it less practical. In contrast, warm water culture can produce market-ready turtles in just 12–14 months, provided that water temperatures are maintained around 30°C throughout the year.
Nutritional challenges in turtle farming have become increasingly significant. If not properly addressed, these issues can lead to economic losses for farmers. To support sustainable development, it's essential to focus on improving feeding practices and nutrition in artificial breeding systems.
**1. Nutritional Needs of Soft-Shelled Turtles**
Soft-shelled turtles require a balanced diet containing protein, fat, carbohydrates, vitamins, and minerals to support their growth and health.
- **Protein**: Essential for body development, especially during the juvenile stage. Studies suggest that protein levels should range from 43% to 50%, depending on the turtle’s age and water temperature. Animal-based proteins, particularly white fish meal, are more efficiently utilized than plant-based sources. A 6:1 ratio of animal to vegetable protein is ideal for optimal growth and feed intake.
- **Fat**: Provides energy and essential fatty acids. Turtles have higher energy needs due to their semi-aquatic lifestyle. Adding oils like corn oil (3–5%) can improve feed efficiency and palatability. Linoleic acid-rich oils are particularly beneficial for growth.
- **Carbohydrates**: While not a primary energy source, they play a role in feed binding. α-starch is most effective, with optimal inclusion levels between 20–30%. Cellulose should be limited to under 10%.
- **Vitamins**: Critical for metabolic functions. Deficiencies in B6, niacin, and B12 can cause poor growth, reduced appetite, and reproductive issues. Complex vitamin supplements are necessary for healthy development.
- **Minerals**: Important for bone formation, blood production, and osmoregulation. Imbalances can lead to diseases and stunted growth.
**2. Unique Nutritional Requirements**
Unlike fish or terrestrial animals, soft-shelled turtles have distinct nutritional needs. They rely more on fat and protein for energy, and their ability to digest starch is limited. This makes it crucial to tailor feeds specifically for their physiology.
**2. Feed Composition and Technology**
As natural food sources become scarce, compound feeds are increasingly used in turtle farming. These feeds are formulated based on the turtle’s life stage and nutrient requirements. Common ingredients include:
- **Fishmeal**: High in protein and essential amino acids, with strong attractant properties.
- **Soybeans**: Provide vegetable protein, especially when full-fat puffed soybeans are used.
- **Yeast**: Rich in B-vitamins and growth factors.
- **α-Starch**: Improves feed texture and binding.
- **Animal By-products**: Such as liver, mussel, and squid viscera, which enhance palatability.
- **Feed Premixes**: Contain vitamins and minerals to ensure balanced nutrition.
**3. Feeding Techniques**
Feeding practices should align with the turtle’s physiological needs:
- Feed should be mixed with water (1:1.2 ratio) and softened before serving.
- Adjust feeding frequency and quantity based on water temperature and growth stage. Optimal feeding occurs at 30°C, with 2–3 meals per day.
- Follow the four principles of feeding: quality, quantity, timing, and location.
By understanding and meeting the specific dietary needs of soft-shelled turtles, farmers can improve productivity, reduce disease risks, and ensure long-term sustainability in turtle farming.
