Nueve medidas para mejorar la calidad de los piensos y reducir sus costos(Ⅱ)

  • Effective nutrition and feeding value of raw materials

Pricing based on available nutrients or available nutrients is an effective way to reduce costs, mainly considering digestible energy or metabolizable energy, digestible amino acids, and available phosphorus. Phytic acid is widely present in plants as a phosphorus reservoir, and minerals are bound in protein-phytic acid-mineral element complexes. Phytase can decompose phytate, reduce the activity of phytate-binding phosphorus, and increase the available phosphorus content.

  • Raw material pretreatment

Raw material pretreatment can improve the digestibility of nutrients, increase the content of effective nutrients, and reduce the cost of formula in formula design based on effective nutrition. Commonly used pretreatment methods include puffing, acidification, enzymatic hydrolysis, fermentation, etc.

  • Application of functional feed additives such as acid preparations

Functional feed additives have been widely recognized and promoted from antibiotic-free feed to animal products without antibiotics. The addition of acid preparations to the feed can reduce the acidity of the feed, lower the pH of the chyme in the stomach, activate pepsinogen, and provide a suitable active environment for pepsin. The low pH environment in the stomach is conducive to the digestion of plant proteins and starches, and is conducive to the degradation of antigenic proteins. In addition, some organic acids (such as formic acid and propionic acid) have strong bactericidal and antifungal effects, and their addition in feed can ensure feed biosecurity. Therefore, the scientific application of acid preparations is an important means to improve the quality and efficiency of feed and aquaculture.

  • Precision Nutrition

The essence of precise nutrition is to ensure the balance of supply and demand. It is necessary to establish an accurate nutrition database to ensure the digestion and utilization rate of nutrients, to define appropriate feeding standards (regional, seasonal, etc.), and to ensure stable feed quality (organic acid fungicides, antioxidants, etc.)

  • Balanced rations

A balanced diet refers to the nutritional level and proportion of the diet, as well as the physical and biochemical properties produced in the digestive tract to achieve the best state, and the animal health and production performance are the highest. The following balances should be fully considered when designing and formulating complete rations:

Protein, energy; energy-to-egg ratio; calcium, available phosphorus, calcium-to-phosphorus ratio; limiting amino acids; ratio of long-chain fat to medium-chain fat; acid-base balance (acid-binding force); Some feed ingredients have strong acid binding power, which consumes part of gastric acid, resulting in reduced gastric digestion and bacteriostatic ability, especially for young animals. Adding acid preparations can effectively reduce the acid power of feed.

  • Appropriate feed processing technology

The nutritional value of feed is not only related to various nutrients in the feed, but also to the processing technology. Appropriate processing technology can not only change the physical structure and chemical properties of the feed, but also promote the easier digestion and absorption of nutrients by animals, thereby improving the quality of the feed. In actual production, the feed processing technology should be reasonably selected according to the actual situation and through the comprehensive effects of different process parameter combinations on the feed processing quality, animal growth performance and nutrient performance digestibility.
