Problems solved by technology

[0002] Since the Danish scientist Poulsen first reported in 1989 that adding 3000mg / kg zinc oxide to the feed of weaned piglets reduced the diarrhea rate of piglets after weaning, the pig industry began to use high-zinc diets to prevent and treat diarrhea in weaned piglets, and achieved certain results. However, high Zinc diet affects the absorption of other trace elements. After 2 weeks of continuous use, piglets are prone to pale complexion, long hair, and anemia. Due to the low bioavailability of zinc oxide, most of it is excreted with feces and pollutes the environment.
According to reports, after feeding high-dose zinc (3000mg / kg) through in vivo digestion and absorption, zinc in excreted feces is as high as 16832.26mg / kg. High-dose zinc will pollute soil and groundwater, affect human life, health, safety, and hinder animal husbandry. sustainable development of the industry

Embodiment 1

[0031] The zinc oxide-free feed for weaned piglets consists of the following components in parts by weight: 20-30 parts by weight of corn, 10-15 parts of baked corn, 5-10 parts of puffed soybeans, 5-10 parts of compressed oats, 8-15 parts of broken rice, and fermented probiotics Feed 5-10, biscuit powder 8-15, fermented soybean meal 2-5, pig spray-dried plasma protein powder, 2-5, super steam fish meal 2-5, yeast extract 2-7, whey powder 5-10, glucose 2-5, sucrose 2-5, organic compound acidifier 1-2, organic mineral premix 1-2, yeast cell wall 0.1-0.3, calcium formate 0.5-0.7, calcium dihydrogen phosphate 0.1-0.5, amino acid, 0.2 -0.5, table salt 0.1-0.3, choline chloride 0.05-0.2, probiotics 0,02-0.05, plant essential oil 0.05-0.2, vitamin premix 0.02-0.04, compound enzyme preparation 0.1-0.4, antimicrobial peptide 0.05- 0.2, antifungal agent 0.05-0.1.

[0032] Preferably, every 1 kg of the organic compound acidifier contains 200-500 g of lactic acid, 10-50 g of fumaric acid...

Embodiment 2

[0050] Product feeding test: select the piglets with consistent quality, similar body condition, healthy and disease-free, and 21-24 days old weaned, and then divide into A group (test group, zinc oxide-free weaned piglet feed of the present invention) and B group according to the similar principle of body weight. group (control group, common weaned piglet feed with zinc oxide), each group had 8 replicates, and each replicated 10 pigs. The feeding period is 10 days.

[0051] Product application location: Hunan Xinxiangnong Ecological Technology Co., Ltd.

[0052] Time: December 2016

[0053] The test data are as follows (Table 1):

[0054] Table 1 Feeding effect of zinc oxide-free diet on weaned piglets

[0055]

[0056] Note: Diarrhea rate = (number of pigs with diarrhea * days of diarrhea) / (number of pigs tested * days of test) * 100%

[0057] The test results show that feeding weaned pigs the zinc oxide-free diet of the present invention can increase the feed intak...

Embodiment 3

[0059] Product feeding test: select the piglets with consistent quality, similar body condition, healthy and disease-free, and 21-24 days old weaned, and then divide into A group (test group, zinc oxide-free weaned piglet feed of the present invention) and B group according to the similar principle of body weight. group (control group, common weaned piglet feed with zinc oxide), each group has 6 replicates, and each replicate has 8 pigs. The feeding period is 10 days.

[0060] Product application location: Hunan Zhuzhou Golden Land Agriculture and Animal Husbandry Development Co., Ltd.

Abstract

The invention discloses a zinc-oxide-free feed for weaned piglets and a preparation method of the zinc-oxide-free feed. The zinc-oxide-free feed is prepared from the following raw materials of corn, baked corn, puffing soybeans, tabletted oat, broken rice, biscuit powder, fermented soybean meal, a probiotic fermented feed, pig spray drying plasma protein powder, a yeast extract, whey powder, glucose, cane sugar, an organic composite acidulant, an organic mineral premix, a yeast cell wall, calcium formate, calcium dihydrogen phosphate, amino acids, table salt, choline chloride, plant essentialoil, a vitamin premix, a compound enzyme preparation, an antibacterial peptide and a mildewproof agent. The zinc-oxide-free feed is characterized in that through massive raw material pretreatment, a probiotic fermented feed is selected, through a secondary-crushing secondary-mixing technology, the palatability and the digestibility of the feed are improved, the immunity of the weaned piglets is improved, the generation of diarrhoea of the weaned piglets is effectively prevented, and a basis is established for later-stage production.
