Animal extracts are made from animal bodies or animal tissues or organs by extraction and boiling with mild enzyme, then concentrated and spray dried into meat extracts. They are a new industry that corresponds to plant extracts. Formerly, they are commonly used as raw products and biochemical raw materials. Its main categories are: amino acids, peptides, proteins, enzymes and coenzymes, polysaccharides, lipids, nucleic acids and their derivatives. The biggest characteristic is that it can dissolve into water. Natural chicken extract, natural pork extract, natural beef extract, natural seafood extract. There are many kinds of seafood, such as shrimp, oyster, abalone, squid, tilapia, crab and so on.

How to prevent grape cracking
Grape cracking is a complex issue influenced by the structure and physiological changes of the grape's skin, as well as environmental factors and agricultural practices. Under normal conditions, the exocarp (outer layer) of the grape continues to split from the stigma outward during fruit ripening, expanding radially around it. As long as this expansion aligns with the fruit's growth, cracking does not occur because the exocarp has strong tensile strength. However, if the grape experiences excessive nutrient imbalance, the exocarp may stop growing prematurely or divide at a slower rate. When the fruit cells grow faster than the skin can expand, cracks are more likely to form.
Grape cracking can occur throughout the fruit development process but is most common during the coloring and ripening stages. Once the fruit splits, it becomes vulnerable to mold, pests like beetles, bees, and flies, which feed on the juice and spread diseases. This significantly impacts both the yield and quality of the grapes. To prevent cracking, several effective measures should be taken:
1. **Maintain consistent soil moisture** – During the early stages of fruit growth, dry soil can lead to stress. When the fruit enters the coloring phase, heavy rain or flooding can cause sudden water absorption, increasing internal pressure and leading to cracking. It’s essential to irrigate when the soil is dry and drain excess water after rain. Ensuring balanced moisture levels throughout the growing season helps reduce the risk of cracking. In the later stages, avoid overwatering, especially flood irrigation, to prevent drastic fluctuations in water content.
2. **Optimize vine management** – Overly dense foliage, excessive leaf area, or improper pruning can hinder nutrient distribution, resulting in thin, fragile fruit that is more prone to cracking. Proper pruning and thinning help improve light exposure and nutrient flow. A recommended approach includes keeping shoots about 10 cm apart, maintaining a leaf-to-bunch ratio of 15–20:1, and adjusting the number of clusters based on vine vigor. Strong vines can carry 2 clusters, while moderate ones carry 1, and weak ones may not carry any. Removing secondary clusters and thinning spikelets also helps balance the load and reduce pressure on individual fruits.
3. **Control pests and diseases** – Poor pest management or incorrect pesticide use can lead to premature leaf drop, reducing transpiration and increasing internal fruit pressure, which can cause cracking. Early detection and treatment of leaf-damaging pests and diseases are crucial to maintaining healthy foliage and preventing fruit damage.
4. **Protect against adverse weather** – High winds or extreme heat during the early fruit stage can contribute to cracking. In such cases, pre-irrigation or misting before hot periods can help cool the plants and reduce the risk of fruit splitting.
5. **Use plant growth regulators carefully** – While these chemicals can aid in fruit set and seedless grape production, improper application can cause cell enlargement and structural weakness, leading to cracking. It’s important to follow guidelines for concentration and timing to minimize this risk.
6. **Prune grape clusters effectively** – Some varieties have tightly packed clusters that increase internal pressure and lead to cracking. Pruning techniques such as removing extra florets and thinning the cluster can help create space and reduce the likelihood of damage.
By implementing these strategies, growers can significantly reduce the occurrence of grape cracking, ensuring better quality and higher yields.
NMN Powder (nicotinamide mononucleotide): full name[ β- Nicotinamide mononucleotide "is a kind of naturally occurring biologically active nucleotide. The decline of NAD in aging process is considered to be the main cause of disease and disability, such as hearing and vision loss, cognitive and motor dysfunction, immune deficiency, arthritis, metabolic disorder and cardiovascular disease caused by autoimmune inflammatory reaction disorder. Therefore, NMN supplementation can increase the content of nad+ in vivo, thus delaying, improving and preventing aging related phenotypes, or age-induced metabolic disorder, aging diseases, etc. Furazolidone powder is mainly used for bacillary dysentery caused by sensitive bacteria, enteritis, cholera, typhoid, paratyphoid, giardiasis, trichomoniasis, etc. Combined with antacids and other drugs in the treatment of gastric sinusitis caused by Helicobacter pylori. Fenbendazole powder, fenbendazole is a kind of benzimidazole insecticide. It not only has high repellent activity to adults and larvae of gastrointestinal nematodes, but also has good effect on reticulum, Fasciola and cestode, and has strong insecticidal effect on eggs. Levamisole hydrochloride is an insect repellent and immunomodulator. It has good curative effect on Ascaris lumbricoides, hookworm, Enterobius vermicularis and strongyliasis faecalis. Albendazole powder is a highly effective and broad-spectrum insect repellent. It is one of the benzimidazole drugs with wide insect repellent spectrum and the strongest insecticidal effect. It can be used to expel Ascaris lumbricoides, pinworm, hookworm, whipworm, treat all kinds of cysticercosis, and also be used to expel livestock.
