Problems solved by technology

In recent years, there have been many studies on improving feed utilization, but they are mainly focused on the use of chemically synthesized additives. Chemically synthesized additives can cause problems such as animal drug resistance and residues, endangering human health, and there are also a large amount of excrement, such as ammonia gas, hydrogen sulfide and other harmful gases, polluting the environment

[0036] Preparation of bacillus natto bacterial agent:

[0037] Insert the slant strain of Bacillus natto into the shaker flask, cultivate step by step to obtain the seed liquid, put the seed liquid into a 1.5-ton secondary seed tank with a total volume of 10% inoculum, and ferment medium with a loading capacity of 1 ton. Conditioned culture temperature is 24°C, stirring speed is 100 rpm, ventilation volume (V / V) is 1:0.5, tank pressure is 0.05MPa, culture time is 30 hours, and the bacterial concentration at the end of culture is 5.0×10 8 pieces / ml. Centrifugal separation: use a centrifuge to separate the fermentation broth to obtain the bacteria. After adding the protective agent, vacuum freeze-drying process was used to obtain the dry powder bacterial agent; the protective agent was composed of 8% skimmed milk, 3% lactose, 2% glycerin, 1.5% trehalose, and the rest was water.

Abstract

The invention discloses a composite feed supplement capable of effectively improving the feed utilization ratio and preparation thereof and belongs to the field of feed supplements. The feed supplement comprises the following raw materials in parts by weight: 20-30 parts of radix asparagi powder, 20-35 parts of echinacea powder, 15-30 parts of cattail pollen powder, 20-30 parts of dogwood powder, 1-5 part (s) of cordyceps taishanensis powder, 1-5 part (s) of cordyceps sinensis fermentation liquor extractive, 2-8 parts of bacillus natto agent, 5-10 parts of radix asparagi composite extractive, 2-4 parts of Aspergillus awamori culture and 0.5-2 part (s) of licorice powder. The raw materials are respectively prepared by a certain methods and are uniformly mixed to obtain the composite feed supplement. The composite feed supplement can effectively improve the immunity and intestinal health of pigs, reduce diseases of pigs, ensure healthiness of pigs, promote growth and development, and simultaneously protect the feed against mildew and nutrient substances against oxidation loss, thereby improving the feed utilization ratio.

Description

Technical field: [0001] The invention relates to a feed additive for pigs, in particular to a compound feed additive that can effectively improve the utilization rate of feed, and to a preparation method of the additive, belonging to the field of feed additives Background technique: [0002] Feed is the main cost of animal breeding. According to statistics, 60%-70% of the cost of animal breeding comes from the cost of feed. Therefore, reducing feed waste and improving feed utilization are the key points to control the cost of breeding and improve the efficiency of breeding. At present, the aquaculture industry generally has problems such as low feed utilization rate, incomplete digestion of nutrients, and poor storage that lead to moisture absorption, mildew or insects in the feed. The existence of these problems not only greatly increases the cost of feeding, but also leads to waste of resources. How to solve these problems, control the cost of breeding, and reduce the risk...
