The invention discloses a stress phosphorylation antibody aiming at a human Tudor-SN protein T103 site and a preparation method thereof. The preparation method adopts a multifunctional human Tudor-SN protein as a research object and comprises the following steps of determining if threonine at a 103 site of a human Tudor-SN protein under external environment oxidation stress is subjected to phosphorylation modification by near-infrared double-color laser imaging and mass spectrometry, synthesizing a T103 phosphorylation site-containing semiantigen polypeptide according to the secondary structure prediction result, coupling the T103 phosphorylation site-containing semiantigen polypeptide and a carrier protein (KLH) into a complete antigen, carrying out immunization on SPF-level New Zealand white rabbit by the complete antigen combined with an adjuvant four times and collecting, purifying and identifying a T103 specific stress phosphorylation polyclonal antibody. In practical application, Tudor-SN protein epigenetic phosphorylation modification in different stress environments can be detected, the effect mechanism of the Tudor-SN protein epigenetic phosphorylation modification in cell stress tumor propagation and migration can be discussed and a latent action target point for clinical tumor disease diagnosis and treatment is provided.

The invention discloses a non-resistant low-zinc low-copper non-plasma high-grade piglet creep feed and a preparation method thereof. The creep feed comprises the following raw materials: corn, flour,broken rice, puffed soybean powder, milk powder, imported fish meal or fish peptide protein, fermented soybean meal, yeast hydrolysate, soybean protein concentrate, fat powder, acidifying agent, fishsolubles, egg powder, calcium lactate, calcium dihydrogen phosphate, lysine, methionine, threonine, tryptophan, trace element composite package, coated zinc oxide, vitamin composite package, plant extract composite package, plant essential oil, antibacterial peptide and microecological preparation. The product does not use homologous proteins such as plasma protein powder so as to effectively block the occurrence of homologous diseases. The product uses low zinc and low copper so as to reduce environmental pollution and improve the utilization rate of land. The product is free from antibioticso as to reduce drug residue and to ensure human food health. The preparation method provided by the invention is simple, the raw material sources are wide, and the use effect is good.
