Overview     The neem tree is also known as the winter melon, the melancholy, the ta tree (distinguished from the Indian oval), the house tree (distinguished from the forest oval), practicing, practicing hard. The tree is native to Asia, but widely distributed almost all over the world, with many different English names such as, Persian lilac, Paradise tree, Pride of India, White cedar... It is a species of the family. Xoan - Meliaceae, with current scientific name is Melia azedarach and synonyms are M. sempervirens, M. australis, M. japonica. Neem tree The neem tree is a small tree with seasonal deciduous trees, the tree is usually 7-20 m high, in some places (Northern Australia) the tree is more than 40 m tall. The plant bears compound leaves, two to three times odd, leaflets serrate; light green young leaves. Flowers are small, white with purple heart, growing in clusters of large canopy, blooming in mid-spring, many trees are full of energy, in the sexual seas...

  A. Overview Enzymes are proteins that act as biological catalysts, participating in important biochemical processes in the animal's body. In aquaculture, the enzymes that have received the most attention are Amylase, Cellulase, Lipase, and Protease. B.  Types of Digestive enzymes 1. Amylase Structure of α-amylase (Source by Wikipedia).   Amylase is an enzyme that catalyzes the hydrolysis of starch into sugars. Amylase exists 3 types, in which the two most common enzymes commonly used in hydrolysis are α-amylase and β-amylase, the other is γ-Amylase. Besides, they have the effect of decomposing starchy ingredients to help animals absorb better. 2. Cellulase Cellulase is an enzyme that breaks down cellulose molecules into monosaccharides (simple sugars) such as beta-glucose, or into shorter polysaccharides and oligosaccharides. Cellulase is produced mainly from fungi, bacteria and protozoa, operating at an optimal pH of 4-5, a temperature of 45-50. Structure of ...

  A.    Overview The scientific name of "Trâm Bầu" is Combretum quadrangular Kurz, also known as "Chưng bầu",  tim bầu, săng kê, song re . In Vietnam, the tree grows wild in all the southern provinces, especially in the Mekong Delta. Shrub or small tree, 2–10 m tall. The stem has many short, deciduous branches that look like thorns. Young branches are 4-sided, with thin edges. Leaves opposite, short petioles. The leaves are hairy on both sides, thicker on the underside. The flowers are small, ivory yellow, growing in spikes in the leaves and branches. The fruit has 4 thin petals, containing a diamond-shaped seed. Trâm Bầu tree   "Tram Bau" has long been considered a precious herb, treating many diseases in humans and aquatic animals with the ability to resist some bacterial species that cause diseases in aquatic animals by extracts from the seeds and leaves of the plant. brooch. The use of antibiotics and chemicals for disease prevention and treatment ...

  A. Overview Yucca schidigera, commonly known as Mojave yucca, is a flowering plant native to the Mòjave Desert, Chihuahuan Desert, and Sonoran Desert of southeastern California, Baja California, New Mexico, southern Nevada, and Arizona. Yucca Schidigera is a small tree in the family Agavaceae and grows to 5 meters tall, with a densely twisted crown arranged bayonet-like leaves on a conspicuous basal stem. The leaves are 30–150 cm long and 4–11 cm broad at the base, convex, thick, very stiff and yellow-green to blue in color.   Because the leaves of the Yucca tree have a fibrous structure, the natives often use the leaves to make ropes, shoes, and clothes. The black seeds of the Yucca plant can be ground for starch, and the flowers and fruit are edible. Their roots can be used medicinally in shampoos. In addition, the extracts from the Yucca plant can be used in animal husbandry such as: making medicine to treat diseases from protozoa for animals, reducing urea and ammo...

  A.     Overview Garlic, scientifically known as Allium sativum, is a familiar spice in daily meals that has very good effects on human health. Garlic is rich in nutrients. According to research, in 100g of garlic contains 6.36g of protein, 33g of carbohydrates, 150g of calories and nutrients such as vitamins of group B (B1, B2, B3, B6), iron, calcium, potassium, manganese, magnesium, phosphorus,. .. The main active ingredients in garlic are sulfur organic compounds and glycosides. In addition, garlic is also high in germanium and selenium. In particular, the germanium content in garlic is higher than that of medicinal herbs such as ginseng, green tea, red tea, etc. The basic effects of garlic mainly come from allicin. In fresh garlic there is no free allicin, only its precursor is alliin. When garlic is minced, the enzyme in garlic is activated which stimulates alliin to form allicin.   Currently, in aquaculture, garlic extract is also widely used in the treatme...

A.    Overview about Povidone Iodine(PVP-I) There are many different types of Iodine with Iodine ingredients and solvents. However, the mention of Iodine in aquaculture is referring to Povidone-iodine (PVP-I). This is a chemical compound belonging to the halogen group with strong oxidizing properties. In terms of chemical structure, it is composed of a complex of soluble solvent, also known as the carrier Polyvinyl pyrrolidone (PVP) with Iodine(I2) and the content of Iodine in PVP-I contains from 9.0% to 12 %. PVP-I in powder form has a dark red color, a characteristic odor, is completely soluble in water, and has higher stability than alcohol iodine and logon. Because of such a structure, when using PVP-I, iodine will be released slowly into the surrounding environment and minimize toxicity to shrimp, fish, and frogs compared to normal forms of Iodine.
