Problems solved by technology

However, the development of pig production has brought some problems that cannot be ignored: 1. The shortage of feed resources restricts the sustainable development of pig industry
According to statistics, the annual gap of energy feed in my country is more than 83 million tons, and the annual gap of protein feed resources is more than 30 million tons. This is undoubtedly the primary factor restricting the future development of the grain-consuming pig industry. severe environmental pollution
Due to the lack of basic research on the biological value of nutrients and nutritional requirements of pig feed resources, the pig feed formula in my country has been unscientific for a long time. In the pig feed formula, the nitrogen content is often 10-20% higher than the actual requirement. Phosphorus is 20-40% high, that is, the national waste of protein feed reaches 8.64 million tons and calcium hydrogen phosphate is 600,000 tons every year, and the economic loss of feed waste reaches 30 billion yuan
At the same time, it also brings serious environmental pollution. According to statistics, a pig farm with 10,000 heads discharges about 80 tons of pig manure every day, and at least 30,000 tons of pig manure is discharged every year, which is equivalent to 107 tons of nitrogen and 31 tons of phosphorus; 1. The quality and safety of pork products are prominent. In order to pursue faster growth and maximize economic benefits, a small number of producers abuse additives such as clenbuterol and sex hormones in feed, as well as animal fats and proteins contaminated by germs. Prohibited drugs and toxic substances in pork products seriously exceed the standard, directly endangering human health; 4. Abuse of antibiotics in feed leads to frequent outbreaks of epidemics
Due to the lack of effective supervision, long-term large-dose abuse of antibiotics in pig feed production has led to the emergence of drug-resistant strains and their transfer to humans, causing zoonotic diseases such as "foot-and-mouth disease", "swine streptococcal disease" and the recent global outbreak of "swine flu" "And the frequent occurrence of epidemics that panicked the world
The existence of these problems has not only led to the low production performance of pigs in my country, high feed costs, low overall benefits of pig farming, but also hindered the healthy and sustainable development of pig production
In order to solve this problem, many people have added products such as probiotics, enzyme preparations or small peptides to pig feed alone, but none of them have achieved ideal results

Embodiment 1

[0012] Examples of feed synergistic additives for pigs of the present invention The distribution ratio of each component by weight is: 1.8% of bacillus, 2.5% of neutral protease, 2.5% of α-galactosidase, 1.0% of threonine, and 0.4% of vitamin E , vitamin A 0.3%, the rest is carrier small peptide; the active ingredients are: Bacillus 1.2×108CFU / / g, protease 1250IU / g, α-galactosidase 6U / g, threonine 10000mg / g , vitamin A 1000IU / g, vitamin E 2.0mg / g.

[0013] The bacillus was produced by Guangzhou Guangmufeng Biotechnology Co., Ltd., the neutral protease was produced by Novozymes, Denmark, the α-galactosidase was produced by Hunan Youtel Biochemical Co., Ltd., and the small peptide used as the carrier was produced by American Sinochem Co., Ltd. Produced by Da Biochemical Technology Co., Ltd. (the same below).

[0014] The preparation method is as follows: (1) weighing the raw materials of each component in proportion, and randomly dividing the carrier small peptide into two part...

Embodiment 2

[0017] The weight percent distribution ratio of each component in this embodiment is: Bacillus 1.5%, neutral protease 2.0%, α-galactosidase 2.0%, threonine 0.8%, vitamin E 0.3%, vitamin A 0.2%, the balance It is a small peptide carrier; the contents of active ingredients are: Bacillus 1.05×108CFU / / g, protease 1050IU / g, α-galactosidase 5.2U / g, threonine 8200mg / g, vitamin A 730IU / g, vitamin A E 1.62 mg / g.

[0018] The preparation method is the same as in Example 1.

[0019] The product of this embodiment was added into the feed formula of 30 growing pigs of about 30.0 kg according to 0.2‰ of the feed weight, and a feeding test was carried out for 36 days. The results showed that the average daily gain of the test pigs in the test group fed the product of this embodiment reached 734.5g, increased by 97.6g compared with the matched group, and all reached a significant difference level (P<0.05) through statistical analysis; the test group fed with the product of this embodiment ha...

Abstract

The invention relates to a pig feed synergistic additive and a preparation method thereof. The pig feed synergistic additive is formed by preparing bacillus, protease, alpha- galactosidase, threonine, vitamin A, vitamin E and carrier small peptide; weight percentage of all components is as follows: 1.5-3.0% of bacillus, 2.0-4.0% of neutral protease, 2.0-4.0% of alpha- galactosidase, 0.8-1.6% of threonine, 0.3-0.8% of vitamin E, 0.2-0.5% of vitamin A and the balance of oligopeptide transporter. The invention also discloses a preparation method for pig feed synergistic additive. The pig feed synergistic additive can increase the nutrient utilization efficiency of pig feed, reduce environmental pollution caused by nutrient over discharge, can obviously increase pig production performance, and effectively improve the immunologic function of the pig.

Description

technical field [0001] The invention relates to a pig feed synergistic additive and a preparation method thereof, in particular to a pig feed composed of bacillus, protease, α-galactosidase, vitamin A, vitamin E and threonine Synergistic additive and its preparation method. Background technique [0002] Pig farming is one of the traditional pillar industries of my country's agriculture. After more than 50 years of development, the number of pigs slaughtered in my country has increased from 58 million in the early days of liberation to 680 million in 2008, an increase of 12 times. Pig production has also gradually developed from traditional free-range farming to intensive large-scale farming. However, the development of pig production has brought some problems that cannot be ignored: 1. The shortage of feed resources restricts the sustainable development of pig industry. According to statistics, the annual gap of energy feed in my country is more than 83 million tons, and t...
