Pig antibiotic-free concentrated feed

Abstract

The invention relates to pig concentrated feed which does not contain antibiotic and hormone. The pig concentrated feed is mainly prepared from the following materials: protein materials, calcium hydrogen phosphate, calcium carbonate, iodinated salt, amino acid, zinc sulfate, sodium selenite, magnesium sulfate and the like. As the pig concentrated feed does not contain the materials such as the antibiotic, the hormone and the like and is added with a proper amount of microelements, the pig concentrated feed can supplement nutrient components of conventional feed, prevent feed quality degradation, improve palatability of the feed, improve the feed utilization rate for pigs, improve disease resistance of the pigs, prompt normal development and quick growth of the pigs, and improve the growth quality of the pigs; and after the pig concentrated feed which serves as an additive is prepared into complete feed, residue of mineral elements in pork and livers of the pigs (the component contentis controlled to be within the safety value during the fattening period) is reduced, edible safety of pork products is ensured, the feed cost is lowered, and the environmental pollution of swine waste is reduced on the premise of not influencing growth performance of the pigs.

Description

technical field [0001] The invention relates to a livestock feed, in particular to a concentrated feed for pigs without antibiotics and hormones. Background technique [0002] With the production of feed, especially mixed feed, large-scale and modern pig breeding becomes possible, and adding some feed additives to feed, such as adding trace elements needed for pig growth, plays a positive role in the growth and development of pigs. The effect can increase the daily weight gain of live pigs, shorten the time for slaughtering pigs, reduce the cost of raising pigs, and achieve better economic benefits, thus bringing about the rapid development and growth of the pig breeding industry, and also making meat in people's daily life Food can be strongly guaranteed. However, in the process of raising pigs, in order to enable pigs to obtain certain disease resistance through food, additives such as antibiotics, antibiotics, and hormones are often added to the feed. Although the additi...

Problems solved by technology

At present, in pig production, minerals are always added in excess, which not only increases the cost of feed, burdens the metabolism of pigs, but also pollutes the environment due to excessive phosphorus, copper, and sulfur in excreta. At the same time, minerals copper, Phosphorus and other residues in pigs will also increase, and some pig feeds are also added with toxic and harmful substances such as arsenic and chromium, which makes pork products unsafe and affects the health of consumers, which also causes minerals to a certain extent. waste of resources
