Embodiment 1

[0020] Example 1. Feed additive composition A for anti-diarrhea of ​​weaned piglets and its effect test

[0021] The anti-diarrhea green feed additive composition A consists of the following parts by mass: 30 parts of nano-montmorillonite, 40 parts of citric acid, and 30 parts of fructooligosaccharide.

[0022] Preparation method: first fully mix nano-montmorillonite with citric acid, and then mix evenly with fructooligosaccharide.

[0023] The animal feeding test of this composition A is as follows:

[0024] 1. Experimental design

[0025] A total of 54 weaned piglets (Duroc × Landrace × Large White) aged 21 days with an average body weight of 5.5±0.1 kg were selected and divided into 3 treatments, 18 pigs in each treatment. 6 replicates per treatment, 3 pigs per replicate. The feeding period is two weeks after weaning, a total of 14 days. Treatment 1 was the control group, whose diet was supplemented with 0.225% zinc oxide and 0.2% 10% colistin sulfate on the basis of th...

Embodiment 2

[0049] Example 2. Feed additive composition B for anti-diarrhea of ​​weaned piglets and its effect test

[0050] The anti-diarrhea green feed additive composition B consists of the following parts by mass: 40 parts of nano-montmorillonite, 30 parts of malic acid, and 30 parts of chitosan oligosaccharide.

[0051] Preparation method: first fully mix nano-montmorillonite and malic acid, and then mix evenly with chitosan oligosaccharide.

[0052] The animal feeding test of this composition B is as follows:

[0053] 1. Experimental design

[0054] A total of 54 weaned piglets (Duroc × Landrace × Large White) aged 21 days with an average body weight of 5.3±0.1kg were selected and divided into 3 treatments, each with 18 piglets. 6 replicates per treatment, 3 pigs per replicate. The feeding period is two weeks after weaning, a total of 14 days. Treatment 1 was the control group, whose diet was supplemented with 0.225% zinc oxide and 0.2% 10% colistin sulfate on the basis of the b...

Embodiment 3

[0066] Example 3. Feed additive composition C for anti-diarrhea of ​​weaned piglets and its effect test

[0067] The anti-diarrhea green feed additive composition C consists of the following parts by mass: 40 parts of nano-montmorillonite, 40 parts of fumaric acid, and 20 parts of chitosan oligosaccharide.

[0068] Preparation method: first fully mix nano-montmorillonite and fumaric acid, and then mix evenly with chitosan oligosaccharide.

[0069] The animal feeding test of this composition C is as follows:

[0070] 1. Experimental design

[0071] A total of 54 weaned piglets (Duroc × Landrace × Large White) aged 21 days with an average body weight of 5.3±0.1kg were selected and divided into 3 treatments, each with 18 piglets. 6 replicates per treatment, 3 pigs per replicate. The feeding period was 28 days. Treatment 1 was the control group, whose diet was supplemented with 0.225% zinc oxide and 0.2% 10% colistin sulfate on the basis of the basic diet. The basal diet is s...

Abstract

The invention discloses a feed additive composite for preventing weaned pigs from diarrhea. The feed additive composite comprises the following substances by mass: 30-40 parts of montmorillonite, 30-40 parts of organic acids and 20-30 parts of oligosaccharides. The feed additive composite has the following beneficial effects: the montmorillonite has high adsorbability and can serve as the sustained-release carrier of the oligosaccharides and acidulants in the digestive tracts of the animals, thus ensuring the oligosaccharides and acidulants to work in the whole intestinal tract, especially continuously playing roles in the hindgut; and the additive amount of the montmorillonite in the daily ration of the weaned pigs can be reduced through sterilization and bacteriostasis of the oligosaccharides and acidulants, thus avoiding the negative effects of the montmorillonite on palatability of the daily ration of the weaned pigs. The results of animal experiments show that the feed additive composite can effectively replace nano zinc oxide and part of feed antibiotics to be used in the daily ration of the weaned pigs, reduce the diarrhea rate of the weaned pigs and improve the survival rate and growth performance of the weaned pigs.

Description

technical field [0001] The invention relates to a high-efficiency dysentery-resistant green feed additive composition for weaned piglets. Background technique [0002] Based on comprehensive consideration of the reproductive performance and production efficiency of sows, and the adaptability of suckling piglets to the external environment, the modern pig industry mostly adopts weaning at 3 to 4 weeks of age. After weaning of piglets, the development of the digestive system is not perfect, the secretion of digestive enzymes and gastric acid is insufficient, and the morphological changes of intestinal epithelial cells affect the digestion and absorption of nutrients. Nutritional diarrhea caused by reproduction is the cause of diarrhea in suckling piglets. Nutritional diarrhea induces viral infection and produces viral diarrhea; low acidity in the intestinal tract of suckling piglets can also cause the reproduction of pathogenic bacteria and inhibit the colonization and breedin...
