Problems solved by technology

[0008] The research and application of probiotics, oligosaccharides and phytase mainly focus on the research and application of single or combined application effects, while there are few research and application reports on the combined use of oligosaccharides, phytase and probiotics , especially the combined application of oligosaccharides, phytase and probiotics to produce new high-efficiency feed additives for pigs has not been reported. The present invention combines the three for the first time to study a new high-efficiency feed additive for pigs

Embodiment 1

[0024] Example 1: Weigh the microecological preparation (containing Bacillus 1×10 8 CFU / g, Lactobacillus 1×10 8 CFU / g, yeast 5×10 7 CFU / g) 100kg, xylo-oligosaccharides (effective content of 20%) 6kg, phytase (enzyme activity 5000U / g) 5kg, put the weighed probiotics into the mixer, add phytase, Mix for 2 to 5 minutes, then add xylo-oligosaccharides and mix for 5 to 10 minutes to obtain the product.

[0025] Applications:

[0026] Test method: Select 90 long × large hybrid growing pigs of the same breed, similar body condition, healthy and disease-free, weighing about 40kg, and randomly divided into control group, antibiotic group and test group according to the principle of similar body weight, with 3 in each group Repeat, every 10 repetitions. The control group was fed with a basal diet, the antibiotic group was supplemented with antibiotics in the basal diet, and the test group was supplemented with 0.15% efficient and environmentally friendly feed additives in the basal diet. T...

Embodiment 2

[0031] Example 2: Weigh the microecological preparation (containing Bacillus 1×10 8 CFU / g, Lactobacillus 1×10 8 CFU / g, yeast 5×10 7 CFU / g) 100kg, xylo-oligosaccharides (effective content of 20%) 6kg, phytase (enzyme activity 5000U / g) 5kg, put the weighed probiotics into the mixer, add phytase, Mix for 2 to 5 minutes, then add xylo-oligosaccharides and mix for 5 to 10 minutes to obtain the product.

[0032] Applications:

[0033] 80 Duchangda growing pigs with an average weight of about 29kg in good body condition were selected and randomly divided into 5 groups, 1 blank group, 1 control group and 3 test groups for 4 weeks (28 days) feeding experiment. 4 replicates per group, 4 pigs per replicate. The blank group was fed with basal diet; the control group was fed with basal diet with antibiotics; the test group was fed with basal diet with 1%, 2% and 3% high-efficiency environmentally friendly feed additives.

Embodiment 3

[0038] Weigh the microecological preparation (containing Bacillus 1×10 8 CFU / g, Lactobacillus 1×10 8 CFU / g, yeast 5×10 7 CFU / g) 100kg, xylo-oligosaccharides (effective content of 20%) 6kg, phytase (enzyme activity 5000U / g) 5kg, put the weighed probiotics into the mixer, add phytase, Mix for 2 to 5 minutes, then add xylo-oligosaccharides and mix for 5 to 10 minutes to obtain the product.

[0039] Applications:

[0040] Test method: 90 Duchangda ternary crossbred growing pigs with a weight of about 25kg and basically the same health status were selected for the test. Randomly divided into three treatment groups, namely the control group, the antibiotic group, and the test group, with 3 replicates for each treatment, 10 pigs in each replicate, half male and half female. The control group was fed a basal diet, the antibiotic group was supplemented with antibiotics in the basal diet, and the test group was supplemented with 0.2% high-efficiency and environmentally friendly feed additiv...

Abstract

The invention relates to a high-efficiency and environment-friendly feed additive for livestock and poultry and a preparation method thereof. The feed additive comprises the following components in percentage by weight: 80-90 percent of microbial ecological agent, 5-10 percent of oligosaccharides and 5-10 percent of phytase. The feed additive can promote the growth of livestock and poultry, improve the feed intake and the feed efficiency, adjust the immunologic function of the livestock and poultry, enhance the ability to resist disease, replace antibiotics to reduce the diarrhea rate and reduce nitrogen and phosphor discharge as well as ammonia emanation in feces, the pollution of extreta to the environment and the costs on feed and cultivation.

Description

Technical field [0001] The invention belongs to the fields of feed industry and animal husbandry, and specifically relates to an efficient and environmentally friendly feed additive for pigs and a preparation method thereof. Background technique [0002] Antibiotics are added to feeds in sub-therapeutic doses, which can increase the daily gain of livestock and poultry and feed conversion efficiency, reduce mortality, and bring huge economic benefits to livestock production. However, due to the large-scale use of antibiotics, its negative effects have become increasingly prominent. Long-term use of antibiotics has led to resistance to pathogens, drug residues in animal products, decreased immunity of livestock and poultry, and endogenous and secondary infections of livestock and poultry. It is potentially harmful to human health. Therefore, many countries have formulated laws and regulations prohibiting antibiotics and chemical synthesis drugs. [0003] Probiotics are considered a...
