Everyone is aware that although crude fiber in feed is not easily digestible, it still plays an essential role in animal nutrition. One of its main functions is to increase the volume of the feed, helping to create a feeling of fullness in the digestive tract. This can help animals like pigs and chickens resist hunger for longer periods. Some studies have used diets with varying levels of crude fiber to feed chickens, and they found that when the crude fiber content is too low, the chickens may experience poor feather growth and even develop behaviors like pecking at their own feathers or licking them. However, when the crude fiber level is appropriately increased, these issues can be reduced.
This happens because the presence of coarse fiber helps the chicken feel satiated, which reduces the urge to eat excessively and prevents behavioral spasms. Additionally, crude fiber stimulates gastrointestinal motility, aiding in the smooth passage of feces and improving overall digestion. It also enhances appetite and supports better metabolic function.
So, does more crude fiber in the feed mean better results? Not necessarily. Excessive crude fiber can actually be harmful to the growth and health of livestock such as pigs and chickens. Feeds high in crude fiber tend to be rough in texture and less palatable. Moreover, crude fiber is hard to break down and can interfere with the absorption of other nutrients by limiting their contact with digestive enzymes. For example, when the crude fiber content in feed is between 10% and 20%, the digestibility of organic matter is around 72%. But when it increases to 40%-50%, this drops to just 54%.
As a result, if pigs or chickens consume too much crude fiber, they may feel full, but their intake of other essential nutrients decreases. This leads to nutritional deficiencies and insufficient energy, which can cause poor growth, weight loss, and lower egg production in hens.
Therefore, it's important to find the right balance—neither too little nor too much crude fiber. For chickens, the recommended crude fiber content should not exceed 5%, with young chicks typically benefiting from 2.5%-3%, while laying hens and breeders may require up to 3%-4.5%. For pigs, the maximum acceptable level is generally 15%-18%. Maintaining these ranges ensures optimal digestion, nutrient absorption, and overall health in both pigs and chickens.
Anti-Ulcerative
Ulcers is commonly known as gastric ulcer and duodenal ulcer, the formation of ulcers is closely related with gastric acid or pepsin digestion. Ulcer disease is a chronic disease, its seizures were cyclical, episodes and remission of alternating appear, and the onset of abdominal pain has a certain rule. The main cause of ulcers include: 1. Helicobacter pylori infection 2. Bad diet 3. Mental factors 4. Drug stimulation. Many patients with gastric ulcer who have taken non-steroidal anti-inflammatory drug history, these drugs will stimulate our gastric mucosa, causing damage, then it will cause ulcer disease over time. The current anti-ulcer drug is mainly focused on reducing gastric acid and enhance the protective effect of gastric mucosa. In recent years,the research and development of anti-ulcer drug progress is faster, effective drugs have been listed, sales are also rising.
