Problems solved by technology

[0003] Although the growth-promoting mechanism of high-dose zinc oxide is not clear at present, studies have shown that high-dose zinc oxide has a special effect on promoting animal growth and reducing diarrhea for early-weaned piglets, while organic zinc and zinc sulfate cannot play a role. The growth-promoting effect of high-dose zinc oxide, so looking for a high-efficiency zinc source to maintain the reduction of diarrhea rate and growth-promoting effect of zinc oxide, and can save non-renewable zinc sources and reduce environmental pollution has always been an important issue in animal nutrition research and development. Hot topics in feed industry and chemical production research

Embodiment Construction

[0011] The particle size of the nano zinc oxide in this embodiment is less than 50nm.

[0012] Effects of Zinc Oxide Nanoparticles with Different Particle Sizes on Production Performance of Animals

[0013] 1. The effect of average 100nm zinc oxide on the performance of piglets under normal zinc conditions

[0014] 1.1 Materials and methods

[0015] 1.1.1 Materials and Design

[0016] Mixed zinc oxide: average 100nm, with a Zn content of 77.32%.

[0017] Feed grade zinc oxide and zinc sulfate.

[0018] A single factor design was used (Table 1). A total of 18 Landrace×Tai weaned piglets with similar blood relationship, age and body weight were randomly assigned to 3 treatments, each treatment had 3 replicates, and each replicate had 2 pigs. The test period is 3 weeks.

Abstract

The invention relates to the application of nano-zinc oxide in piglet feed, wherein, the particle size of the nano-zinc oxide is less than 50nm. In the invention, the nano-zinc oxide has antibacterial and growth-promoting effects; in the feed for early weaned piglets, the nano-zinc oxide with less than 50nm of physical size has significant positive effect of nutritional physiology. 50 - 100ppm of low-dose added nano-zinc oxide can obviously improve the piglet production performance and save the zinc source in the post-test and the entire test period. The invention uses the nano-zinc oxide with the particle size less than 50nm to replace the ordinary zinc oxide in the piglet feed, wherein, 100-300 grams / ton of the nano-zinc oxide with the particle size less than 50nm can replace 3000 grams / ton of ordinary zinc oxide and can achieve the same effect, so as to reduce the adding amount of ordinary zinc oxide and greatly decrease the production cost; therefore, the nano-zinc oxide has very good social value and economic value and is easy to promote.

Description

technical field [0001] The invention relates to the application of nanometer zinc oxide in piglet feed. Background technique [0002] Since Todd's first research in 1934 proved that zinc is an essential trace element in the growth of rats (Todd1934), a large number of scientific studies have shown that zinc is an essential trace element for animal survival, growth and production of animal products, and has important nutritional and physiological functions . In the early 1980s, the discovery of zinc finger proteins (zinc fingerproteins, ZFPs) and subsequent studies showed that zinc also plays a very important role in genetic material (Chothia, 1992; Shi, 1995; Berg, 1996), and zinc content is an important factor affecting gene expression. A key factor in the development of social media (Lepage, 1999; Kindermann 2004). Studies of high-dose zinc oxide (2000-3000mg / kg) have shown that it can reduce the diarrhea rate of piglets and improve production performance, but it also br...
