Antibiotic-free ecological feed formula for fattening pigs

Abstract

The invention discloses an antibiotic-free ecological feed formula for fattening pigs. The feed comprises the following components of 60-65% of corn, 15-18% of wheat bran, 1-2% of fish meal, 15-17% ofsoybean meal, 0.5-1% of calcium hydrogen phosphate, 1-2% of stone powder, 1-1.5% of a mixed bacteria fermentation preparation and 1-1.5% of a premix. The microecological preparation is added to the feed, so that the self immunity of animal organisms can be mobilized and strengthened, and the balance of gastrointestinal bacterial flora is regulated; and the formula is adjusted, so that requirements for various nutrients and trace elements, required for growth and development of the fattening pigs are met, increment of the weight gain rate of the pigs is facilitated, and the raising cost is reduced.

Description

technical field

[0001] The invention relates to a pig feed, in particular to an antibiotic-free ecological feed formula for fattening pigs. Background technique

[0002] Medicated feed additive is an additive made of antibiotics or chemical drugs, which is expensive to use. While killing pathogenic bacteria, it also kills the normal flora in the intestinal tract of animals, and it is easy to produce drug residues, which reduces the quality of animal products; In addition, continuous single use will cause pathogenic bacteria to develop drug resistance. With the country's restrictions on drug feed and the improvement of its standards, traditional feed can no longer meet the needs of healthy and rapid growth of fattening pigs. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a green and safe fattening pig feed without antibiotics in order to solve the problems caused by the antibiotics in the current pig feed. [0...
