Problems solved by technology

[0003] Adding 2500-4000mg / kg zinc (zinc oxide) to the diet has a significant growth-promoting and anti-diarrhea effect on weaned piglets, but high doses of zinc oxide will cause certain toxic effects on piglets, resulting in thick and long hair and dull skin and affect later growth and development
At the same time, most of the high-dose zinc oxide is excreted into the environment with feces, causing environmental pollution.

Embodiment 1

[0016] At the beginning of weaning of 25-day-old piglets, the control group was fed the control diet (see Table 1 for formula). On the basis of the diet of the control group, 0.06% of coated zinc oxide or 0.1% of sodium butyrate was added to the complete feed of the test group, and the above feed was fed until 46 days old, and the growth performance of piglets was measured.

[0018]

[0019] The test results showed that compared with the control group, the average daily gain of piglets in the coated zinc oxide test group increased by 10% (P<0.05), the feed-to-weight ratio decreased by 6% (P<0.05), and the diarrhea rate decreased by 45% (P<0.05). 0.05), the height of jejunal villi increased by 20% (P<0.05), the depth of crypts decreased by 10% (P<0.05), the activity of duodenal enterokinase increased by 18% (P<0.05), and the activity of jejunal mucosal lactase increased 15% (P<0.05), the invertase activity in...

Embodiment 2

[0021] At the beginning of weaning of 25-day-old piglets, the control group was fed the control diet (see Table 1 for formula). On the basis of the diet of the control group, 0.06% of coated zinc oxide and 0.1% of sodium butyrate were added to the full-price feed of the test group. The piglets were fed with the above feed until 46 days old, and the growth performance of piglets was measured.

[0022] Table 1 Test diet composition and nutritional indicators

[0023]

[0024] The test results showed that compared with the control group, the average daily gain of piglets in the test group increased by 20% (P<0.05), the feed-to-weight ratio decreased by 10% (P<0.05), and the diarrhea rate decreased by 75% (P<0.01). The height increased by 60% (P<0.05), the crypt depth decreased by 20% (P<0.05), the activity of duodenal enterokinase increased by 30% (P<0.05), and the activity of jejunum lactase increased by 25% (P<0.05). 0.05), the invertase activity increased by 30% (P<0.05). ...

Embodiment 3

[0026] At the beginning of weaning of 21-day-old piglets, the control group was fed the control diet (see Table 1 for formula). On the basis of the diet of the control group, 0.2% of coated zinc oxide and 0.2% of sodium butyrate were added to the complete feed of the test group, and the above feed was fed to 42 days old, and the growth performance of piglets was measured.

[0028]

[0029] The test results showed that compared with the control group, the average daily gain of the piglets in the test group increased by 31% (P<0.01), the feed-to-weight ratio decreased by 12% (P<0.05), and the diarrhea rate decreased by 80% (P<0.01). The height increased by 90% (P<0.01), the crypt depth decreased by 50% (P<0.05), the activity of duodenal enterokinase increased by 35% (P<0.05), and the activity of jejunum lactase increased by 35% (P<0.05). 0.05), the invertase activity increased by 60% (P<0.01).

Abstract

The invention discloses a piglet intestine nutrition regulation and control feed based on cladded zinc oxide. The complete feed comprises 0.06-0.2wt% of cladded zinc oxide and 0.1-0.2wt% of sodium butyrate. The cladded zinc oxide is prepared by performing cladding on ingredients such as stearic acid, long-chain rice bran oil, silicate and carboxymethyl cellulose sodium by use of an inlaid cladding technology, has the effect of effectively preventing zinc oxide from being acidified into zinc ions and consuming hydrogen ions in piglet stomaches and is capable of improving the activity of pepsin, so that the active ingredient (zinc oxide) efficiently enter into an intestinal tract so as to exert effects of resisting bacteria and protecting intestinal mucosa mucoprotein structure; sodium butyrate has an effect of rapidly supplying energy nutrients to piglet intestine mucous cells, and has a food attractant effect on piglets due to unique smell. Cladded zinc oxide and sodium butyrate can achieve a synergetic effect and exert respective effects of protecting the intestinal mucosa mucoprotein structure and promoting mucosa epithelial cell growth, and the effects of improving the feed intake of weanling piglets and obviously reducing the after-weanling diarrhoea rate. The piglet intestine nutrition regulation and control feed is capable of obviously reducing the diarrhoea rate of weanling piglets and improving the feed intake and growth property of the weanling piglets.

Description

technical field [0001] The invention relates to a feed for regulating intestinal nutrition of piglets based on coated zinc oxide. Background technique [0002] The modern pig industry usually adopts early or ultra-early weaning, which can easily lead to the reduction of immune function and diarrhea of ​​early weaned piglets, intestinal structural and functional disorders, and even death in severe cases. In order to solve the "weaning syndrome" of weaned piglets. [0003] Adding 2500-4000mg / kg zinc (zinc oxide) to the diet has a significant growth-promoting and anti-diarrhea effect on weaned piglets, but high doses of zinc oxide will cause certain toxic effects on piglets, resulting in thick and long hair and dull skin and affect later growth and development. At the same time, most of high-dose zinc oxide is excreted into the environment with feces, causing environmental pollution. Therefore, it is of great significance to develop a high-efficiency, safe and new zinc oxide...
