Description
Technical field
The invention belongs to feed additive field, be specifically related to a kind of feed addictive for the deodorizing of pig house mosquito repellent.
Background technology
In recent years; along with develop rapidly intensive, large-scale cultivation; animal husbandry has greatly met the demand of people to livestock products such as meat, eggs and milks on the one hand; also some negative effects have been brought on the other hand; as problems such as the appearance of antibody-resistant bacterium, irritated toxic reaction and livestock products medicament residues; the impact of the environmental pollution of animal husbandry simultaneously also has the trend of continuous expansion, shows according to State Environmental Protection Administration's investigation, and the pollution that livestock-raising produces has been the main source of environmental pollution.
The source of plant's odorous gas, except body internal protein and amino acid degradation produce a large amount of urea, in enteron aisle, urea decomposition produces ammonia, in urine, the generation of ammonia is also because urase acts on urea, and after fecaluria mixing, bacterium in excrement can promote the activity of urase, promotes ammonia to overflow in a large number from urea; Also has the indoles material of the hypertoxic hydrogen sulfide of indigested sulfur-containing amino acid decomposition generation, excessive tryptophan degraded generation etc. Wherein, ammonia and hydrogen sulfide are the main foul smell index gas of plant. Ammonia (NH3) is a kind of alkaline molecule, and mucous membrane is had to strong impulse, sucks by respiratory tract, and entering blood can combine with hemoglobin, occurs the symptom such as anaemia and histanoxia, reduces the resistance against diseases of animal. Hydrogen sulfide is also a kind of gas of stench, the same with ammonia, main irritates nucous membrane, and often the hydrogen sulfide of inhalation of low concentration can cause autonomic nerve disorder, and the hydrogen sulfide of high concentration can directly suppress respiratory center, causes and suffocates and death.
At present, the stocking density of large-scale cultivation field is large, and temperature is high, and high humidity adds that ventilation is not smooth, not only makes the pernicious gas of breeding environment accumulate, also for the growth breeding of mosquito provides good condition. Mosquito, as a lot of transmission of disease media, inhales livestock and poultry blood by thorn bacterium, virus is propagated to healthy livestock and poultry, when serious, brings acute epidemic situation to animal husbandry, causes a large amount of losses.
Therefore, the improvement of livestock-raising environment is the large problem that current aquaculture healthy and rapid development is needed solution badly.
At present, about the research of deodorant, there are reports, mainly contains following several types: absorbent-type, perfume masking type, chemical action type, enzyme preparation type, microbiocidal, plant type. But all there is certain shortcoming and defect in the above-mentioned type deodorant, as absorbent-type and perfume masking type deodorant addition in feed large, or directly join in ight soil or bedding and padding, fundamentally do not eliminate the foul smell molecules such as ammonia, enter soil with ight soil and easily cause Soil Nitrate content to increase; Chemical action type deodorant is converted into the material of odorless by reaction by foul smell molecule, but nutrition could not be made full use of, and enter soil and easily cause secondary pollution; The activity of enzyme preparation and microbiocidal is subject to the impact of high temperature in feed process, in actual applications poor effect.
In recent years, along with deepening continuously that people are familiar with ecology, environmental protection, research and the application of plant type deodorant obtain extensive concern. Yucconin is a kind of active ingredient in yucca extract, and research shows, yucca extract can suppress urease activity, reduces generation and the discharge of ammonia, can also promote microorganism to utilize enteron aisle ammonia as nitrogenous source synthesising thalli protein, improves the utilization rate of nitrogen. Cinnamic acid is a kind of plants essential oil extracting from cinnamomum cassia presl plants, there is volatility and broad-spectrum antibacterial action, mosquito is also had to certain killing action, can also strengthen the motion of stomach and intestine simultaneously, promote nutrient digestion, research in chicken feed shows, cinnamic acid can, by suppressing the activity of xanthine oxidase, directly reduce the generation of uric acid, suppresses the activity of urease-producing, uricase simultaneously, thereby effectively reduce the discharge of chicken farm ammonia, but application in pig feed have not been reported. Anise alcohol is the plants essential oil of a kind of slightly sweet taste fragrance in fennel plant, thereby can reduce by suppressing the growth and breeding of enteron aisle aerogenic bacteria the generation of the pernicious gases such as methane, ammonia, improves the Retention of nitrogen. Allicin is to extract and obtain from the bulb of Liliaceae allium garlic (garlic), add energy stimulating animal appetite in feed, increase gastric secretion and gastrointestinal peristalsis, promote the digestion of nutriment, in addition the oxygen atom in allicin molecule can be combined as cysteine, paddy cystine containing the compound of sulfydryl, reduce the generation of hydrogen sulfide gas, also as pesticide. Tea Polyphenols is a kind of main active in mate extract, reports that Tea Polyphenols deodorization functions may be to provide H by catechin+With NH3Reaction generates ammonium salt and foul smell is weakened or disappear, and Tea Polyphenols also has certain inhibitory action to urase and aerogenic bacteria in addition, and Tea Polyphenols also can effectively have removing toxic substances, preventive and therapeutic effect to bacterium, the virus etc. of killing propagation.
