Donkey Disease Characteristics
Donkeys and horses, although both are equines, have distinct biological and physiological differences. While they share similar traits, their responses to illness, disease resistance, and clinical symptoms differ significantly. This makes donkey diseases unique in terms of causes, progression, and symptom presentation. The types of diseases that affect donkeys are similar to those seen in horses, including internal medicine issues, surgical conditions, obstetric problems, infectious diseases, and parasitic infections. Common ailments like gastric distension, constipation, sore throat, and glandular fever can occur in both species. However, donkeys often show different signs of illness compared to horses. For example, while a horse may clearly display symptoms such as lameness or fever, a donkey might appear more subdued or even show no visible signs at all. Donkeys are highly sensitive to nasal infections and are prone to sepsis following bacterial exposure. Yet, they tend to be more resistant to certain diseases like infectious anemia. Additionally, donkeys are less likely to suffer from heat stroke or sunburn than horses, which is another key difference in their disease profiles. Some diseases are specific to donkeys, such as moldy corn poisoning, or the prenatal omnivorous condition seen in female donkeys. These unique health challenges mean that veterinary care for donkeys should not simply follow the treatment protocols used for horses. Instead, it must take into account the specific needs and characteristics of the donkey.Distinguishing Between Healthy and Unhealthy Donkeys
A healthy donkey is usually alert, with both ears erect and a lively demeanor. They move freely, hold their heads high, and show energy. Male donkeys, especially, will often stare, vocalize, and attempt to approach others when they sense a similar presence nearby. When eating, they chew vigorously and make characteristic "princess" sounds. If someone walks by the trough, they may respond with loud braying. Healthy donkeys have a bright mouth color, a moist nose, and warm, responsive ears. Their feces should be firm but not hard, shiny on the outside, and yellow when fresh. Over time, they turn brown. A healthy donkey may snore slightly when swiping its nose. As the saying goes, "A donkey's squeak is stronger than a yak's strength," implying that donkeys rarely suffer from minor illnesses. However, this doesn’t mean they are immune. They have a strong tolerance for common ailments and may continue to eat and drink even when sick. It’s only when they stop eating or drinking that the problem becomes noticeable. To determine if a donkey is unwell, observe its eating behavior and the temperature of its nose and ears. If the donkey lowers its head, shows a lack of interest in food, or refuses to drink water, it could be a sign of illness. Reduced water intake is a key indicator of potential health issues. Hard, dry feces with some mucus may signal an upcoming gastrointestinal problem. If a donkey stops eating for a night but remains standing in the feeding area, and its nose and ears are normal with a regular body temperature, it may still be healthy. The animal may resume eating the next morning. Donkey health is often influenced by weather, seasonal changes, feed quality, and management practices. Therefore, careful observation and proper care tailored to their specific needs are essential for early detection and prevention of illness. By understanding their natural behaviors and physiological traits, breeders can maintain good health and ensure timely treatment when needed. Additionally, if a donkey lies down for extended periods or appears weak even when standing, or if the owner notices unusual attachment or lack of movement, these could be signs of serious illness and require immediate attention.Amino acids are the basic units of proteins and are essential organic compounds in life. There are about 500 different amino acids in nature, but among the amino acids that make up the proteins of living organisms, 20 are standard amino acids, which are connected in different sequences to form proteinaceous proteins that perform various physiological functions in living organisms.
Amino acids can be divided into the following categories according to their location and function in proteins
1.Essential amino acids
9 amino acids that the body cannot synthesize by itself or the synthesis speed cannot meet the needs, and must be ingest through food, including lysine, tryptophan, phenylalanine, methionine, threonine, isoleucine, leucine, valine and histidine (infants also need histidine).2.Non-essential amino acids
The human body can synthesize by itself and does not need to obtain directly from food, including glutamic acid, aspartate, alanine, serine, glycine, proline, cysteine, etc.3.Conditional essential amino acids
Under specific conditions (such as disease, stress), the human body's synthetic ability is reduced, and additional supplements are needed, such as arginine, glutamine, etc.Amino acids are also widely used in the field of skin care, as skin care ingredients, they mainly have the following effects
1.Moisturizing
Some amino acids such as glycine, alanine, etc. have good hygroscopic properties, which can help the skin retain moisture and enhance its moisturizing ability.2.Repair
Such as arginine, glutamic acid, etc. participate in the repair and regeneration process of skin cells, promoting wound healing.3.Anti-aging
Certain amino acids have antioxidant effects that can help fight free radical damage and slow down skin aging.4.Cleansing
Amino acid surfactants, such as sodium lauryl sarcosine, are commonly used in cleansing products for sensitive skin due to their mild, non-irritating properties.Therefore, amino acids are not only essential for human health, but also play an important role in beauty and skin care products.
