Garantizar la salud intestinal y ayudar a que la alimentación de las aves “aumente la eficiencia y reduzca costes”

1.The importance of gut health

As the main digestive organ of the animal body and the largest immune organ in the body, the intestine plays an important role in the growth and development of poultry and the entire production process. Gut health is a necessary condition for animal health and is an important part of poultry production. Imbalance in intestinal health will affect the digestion, absorption and utilization of nutrients by poultry, often manifested as feed feces, water feces, etc., affecting feed efficiency and growth rate, and even leading to increased mortality. For example, the appearance of feed in broiler chickens can lead to a reduction of 100-250 grams of slaughter weight, an increase of 0.1-0.3 in the feed-to-meat ratio, and 20% to 30% of chickens cannot reach the standard slaughter weight. Therefore, maintaining intestinal health is the premise and basis for efficiency and cost reduction of poultry feed.

  • The threat of raw material substitution to intestinal health

There are many factors affecting the intestinal health of poultry, such as breed, feed nutrition, feeding management, biosecurity, disease prevention and control, etc. Among them, feed nutrition is the basis of growth and development, and feed costs account for about 70% of poultry production costs, and the level of feed costs significantly affects production benefits. At present, the prices of raw materials such as corn and soybean meal have skyrocketed, and the substitution of raw materials is a topic of great concern to practitioners. The main alternative raw materials for corn are: (1) wheat, barley, sorghum, aged rice, broken rice, brown rice, cassava, peas and other grains; (2) wheat bran, secondary flour, rice bran, rice bran meal, DDGS, corn germ Meal and other by-products. The main substitute raw materials for soybean meal are: (1) miscellaneous meal such as rapeseed meal, cotton meal, peanut meal, sunflower meal, sesame meal, palm meal; (2) fermentation by-products such as monosodium glutamate residue, amino acid residue, soy sauce residue, and vitamin residue .

Among the above-mentioned alternatives for corn and soybean meal raw materials, the following three situations have more prominent effects on intestinal health: (1) the wheat feed contains more non-starch polysaccharides; (2) the content of mycotoxins in the raw materials of agricultural and sideline products (3) Miscellaneous meal protein digestibility is low and contains more anti-nutritional factors.
