The replacement of antimicrobial agents and the health and pig technology of the dragon academician
Antibacterial agents and healthy pig technology.
The institute of subtropical agricultural ecology of the Chinese academy of sciences.
A study on reducing the use of livestock and poultry health breeding system for antimicrobial agents - an experiment.
1. Overall research idea.
Reduced flushing water: half leaky floor (patent)
Avoid drinking water from pigs.
The rate of diarrhea decreased by 30% to 50% after improving the feeding environment.
2. Feed processing technology and preservation.
The expansion process improves the utilization rate of feed.
A. starch, NPS and protein digestion were better, and the feed conversion rate increased by 4%.
B. The liquid teaching tank will account for about 50% of the large pig farms abroad, and the digestive rate will increase by 2-3 percent, so as to minimize the adverse effects of dust on piglets.
2. Preservation agent: anti-oxygen and anti-mildew - plant essential oil.
To tertiary butyl hydroquinone (TBHQ), feed grade ethoxy quinoline (EMQ), tea tree oil, synergistic agent, chelating agent, surface active agent and synergistic agent has antioxidant and anti-mildew growth promoting ingredients with a scientific formula made from technology and unique production process of high efficiency, non-toxic, at the same time which have multiple functions such as oxidation resistance to mildew growth promoting a new type of antioxidant anti-mildew feed additives.
Integration of mother and child: the growth performance of piglets was decreased with the oxidative damage of female pigs.
Lysozyme: lysozyme is widely used to kill harmful bacteria, promote the growth of beneficial bacteria, and significantly improve the intestinal microecology.
A. antibody detection: the group of pigs in the test group was able to resist the blue ear and the swine fever virus, and the antibody titer was significantly higher and more orderly after the superimmunity of swine fever.
B. by the test results prove that: fermentation lysozyme is animal nonspecific immune factors, involved in the body's immune response, protection against virus invasion, improve antibody drop degree, of blue ear virus, swine fever virus has a significant role.
The evaluation and evaluation of the nucleotide in piglet's teaching trough: the yeast nucleotide can promote the intestinal development of piglets after weaning.
Effect of acidizing agent on the growth performance of weaned piglets.
5 advantages of peptides
No need to digest, direct absorption, absorption rate is greater than the amount of free amino acid absorption rate;
Peptide absorption can avoid the absorption competition between amino acids;
The absorption energy of the peptide is low or no energy consumption; No increase in intestinal burden.
The absorption of small peptides and free amino acids is a completely different mechanism, which can make the substrate more adaptable to different physiological states and daily food changes. When an animal is unable to absorb an amino acid properly due to disease or other factors, it can be supplemented by adding a peptide containing this amino acid.
The absorption of trace elements is promoted, and the microelement as the ligand of the peptide can be directly passed through the intestinal mucosal cells.
Many of the essential amino acids necessary for the synthesis of milk proteins are derived from amino acids which are binding in the form of small peptides, so peptides are particularly important for nursing sows.
Efficient application of feeding plant and its extract.
1 wood feed to improve the flavor of pork.
2 Chinese herbal medicine commonly used in pig industry.
3 Chinese herbal medicine commonly used in poultry.
4 The inhibitory effect of various essential oils on e. coli and salmonella.
5 The expression of il-17 was promoted by GABA (gamma-aminobutyric acid) to promote ETEC infection in the small intestine.
6 aromatic amino acids (TPT)
7 Serum cytokines.
8 TPT can activate the CaSR signaling pathway in piglet's intestinal tract and inhibit NF- kappa B signaling pathway.
9 aromatic amino acid (TPT) ratio.
10 arginine family substance.
12 Taurine: taurine improves the performance and feed efficiency of piglets.
