Problems solved by technology

Animal production practice has proved that there are many problems with inorganic mineral elements used as trace mineral element feed supplements: first, sulfates are likely to cause gastrointestinal ulcers in animals, causing stress in the digestive physiological environment, causing death in severe cases, and affecting growth in light cases, reducing feed Utilization efficiency; the second is that sulfate dissociates into ions under acid and alkali conditions in the digestive tract, and is easily combined with other substances to form substances that cannot be absorbed (such as oxalate, phytate, etc.), which significantly reduces the concentration of trace elements. Digestion and absorption efficiency (the average utilization efficiency is less than 50%, and the utilization efficiency may drop below 10% when the amount of trace mineral elements is used in a large amount), resulting in a great waste of mineral resources and even serious environmental problems; 3. It reduces the biological potency of vitamins, promotes lipid oxidation or peroxidation, and seriously reduces the nutritional quality of feed

Embodiment 1

[0008] Select the nano-zinc oxide whose powder particle size is not more than 40 nanometers, take by weighing 7g nano-zinc oxide (that is, be equivalent to 0.007% of compound feed) per 100 kilograms of experimental compound feed, 7000 grams of diluent (1000 grams of calcium carbonate, calcium hydrogen phosphate 1500 grams, α-starch 4500 grams) after mixing uniformly, detect again, make its coefficient of variation CV of mixing uniformity be no more than 6%, repeated detection error is no more than 5%.

[0009] Experimental effect of monomer nano-zinc oxide: the feeding effect of 0.007% nano-zinc oxide (equivalent to half of zinc requirement) in the compound feed was tested with weaned piglets with an average body weight of 8.16 kg.

[0010] Three groups were set up in the experiment: control group (without adding any zinc source); zinc sulfate group (supplemented according to zinc requirement); nano-zinc oxide group (supplemented according to half of zinc requirement, ie 0.007%...

Embodiment 2

[0018] Select nano-zinc oxide, nano-iron oxide, and nano-titanium oxide with a powder particle size of not more than 40 nanometers, and weigh 7, 6, 2 g and 7000 grams of diluent in turn (1000 grams of calcium carbonate, 1500 grams of calcium hydrogen phosphate, 4500 grams of a starch ) after mixing evenly, then detect, make the coefficient of variation CV of its mixing uniformity be no more than 6%, repeated detection error be no more than 5%.

[0019] Experimental group of weaned piglets with an average body weight of 6.5 kg and the feeding effect of nano-mineral elements.

[0020] Three groups were established in the experiment: control group (without adding any zinc source); zinc sulfate group (supplemented according to zinc requirement); nano mineral element group (nano-zinc oxide 0.007%, nano-iron oxide 0.006%, nano-titanium oxide 0.002% ).

[0021] The basic compound feed for piglets is formulated according to the requirements of piglets in the 5-10 kg body weight stage...

Embodiment 3

[0028] The experimental design was carried out in the manner of Example 1.

[0029] Weaned piglets with an average body weight of 8.2 kg were used to test the inhibitory effect of 0.007% nano zinc oxide on microorganisms.

[0030] After six weeks of the experiment, samples were taken to analyze the logarithmic changes of Escherichia coli and Lactobacillus in the digestive tract. The results are as follows:

[0031] Control group: Escherichia coli 7.88, Lactobacillus 10.26.

[0032] Zinc sulfate group: Escherichia coli 7.72, Lactobacillus 9.86.

[0033] Nano zinc oxide group: Escherichia coli 6.66, Lactobacillus 10.14.

[0034] It can be known from the experimental results that the use of nano-zinc oxide, nano-iron oxide, and nano-titanium oxide in piglet compound feed can significantly inhibit the growth and reproduction of Escherichia coli without affecting the growth and reproduction of lactic acid bacteria, which is beneficial to enhance the health protection of weaned pi...

Abstract

The invention discloses a preparation method of nanometer microelement feed addictive which comprises mixing nano microelements and deflocculating agent, charging into mated feed or premixed feed, the method can increase the nutritive efficiency of the mineral elements.

Description

technical field [0001] The invention relates to a preparation method of a nano-trace element feed additive. technical background [0002] Trace element feed additives or premixes are important trace components in the preparation of complete compound feeds in animal production, and are also an important means of tapping the potential of feed and animal production. For a long time, the trace elements used in the feed industry and animal production are mainly inorganic salts. Animal production practice has proved that there are many problems with inorganic mineral elements used as trace mineral element feed supplements: first, sulfates are likely to cause gastrointestinal ulcers in animals, causing stress in the digestive physiological environment, causing death in severe cases, and affecting growth in light cases, reducing feed Utilization efficiency; the second is that sulfate dissociates into ions under acid and alkali conditions in the digestive tract, and is easily combin...
