Micro Emulsions in Poultry

Micro Emulsions in Poultry

Micro emulsions in Poultry are dispersions of oil and water with an emulsifier. They are clear, thermodynamically stable, isotropic liquid mixtures. They are super solvents which improves stability and thermodynamic activity of formulation. Micro emulsions are beneficial to be used because it increases efficacy of the formulation allowing dose reduction. The average particle size of micro emulsion is 0.1 micrometer which helps in increasing the interfacial area thereby allowing active ingredient to get released easily. In poultry, micro emulsions are designed to include natural essential oils cell wall which in turn binds to mycotoxins to protect animals against mycotoxosis.

Vinayak Ingredients have introduced micro emulsion which is an alternative to antibiotics named as Herbofloxin. It is of natural origin prepared from essential oil of syzygium, citronella, thymus, eucalyptus. Herbofloxin has a particle size less than 0.1 micrometer which makes it easily soluble in water. It maintains poultry gut’s pH-6.5 to 6.7 which is slightly acidic. As it is a micro emulsion it has better dispersion in water, stable at 45 degree Celsius temperature and has a longer shelf life. All these factors makes it safe to be consumed by poultry without having any side effects which are otherwise usually caused by using antibiotics. Herbofloxin is natural replacer for antibiotic growth promoters.

Mechanism of action: Herbofloxin being a micro emulsion when mixed with water forms nano emulsion due to which particle size decreases further making it easier to penetrate the bacterial cell wall and disrupt it. Disruption of cell wall leads to killing of bad bacteria such as Escherichia coli, Campylobacter, Clostridium and Salmonella. Thus it acts like a bacteriostatic. It also acts as an anti-inflammatory by improving mucin coverage which is a first line of defence in poultry.

Herbofloxin as a micro emulsion replaces antibiotics such as tetracycline’s, fluoroquinolones, amino glycosides and selectively modulates poultry gut to promote the beneficial microflora.

MICROBIOLOGICAL SIGNIFICANCE OF POULTRY LITTER

MICROBIOLOGICAL SIGNIFICANCE OF POULTRY LITTER

Chicken litter consists of a mixture of feces, wasted feeds, bedding materials, and feathers. Poultry manure contains critical measures of nitrogen on account of the nearness of abnormal amounts of protein and amino acids. Inferable from its high supplement content, chicken litter has been thought to be a standout amongst the most significant creature squanders as natural manure. Chicken litter is furthermore the wellspring of human pathogens, for instance, Salmonella, Campylobacter jejuni, and Listeria monocytogenes, which can spoil the earth and are as frequently as could be expected under the circumstances associated with sustenance borne flare-ups. Composting of poultry waste preceding the application to horticultural area as natural manure is typically prescribed to control pathogens at last items.

Dynamic observation information on sustenance borne ailments from the United States uncover that among pathogens connected with nourishment borne flare-ups, Salmonella, E. coli O157:H7, Campylobacter, and L. monocytogenes are in charge of the majority of outbreaks. Salmonella spp. is the most broadly circulated pathogen in chicken litter with poultry and eggs remaining as the dominating reservoir. Amid 1998–2008, foodborne disease outbreaks brought on by Salmonella were related most usually with poultry meat items (30%) and eggs (24%).  Chicken eggs can be contaminated with Salmonella either horizontally or vertically. The contamination of egg shell can come about because of horizontal transmission, for example, fecal contact. And, vertical transmission of Salmonella has been seen in infected ovaries, oviducts, or contaminated eggs. Although just low quantities of Salmonella can defile eggs through the fecal course, these little population cannot be disregarded. Notably, S. Enteritidis, S. Typhimurium, or S. Heidelberg present in chicken defecation may infiltrate into the inside of eggs as well as multiply during storage. Salmonella is all the more regularly confined from chicken litter or fecal specimens when contrasted with different pathogens being researched and its pervasiveness level can go generally from 0 to 100%.  And the number of in chicken litter can go from 4 to 1.1 × 105 MPN/g litter.

Pathogens can be transmitted to individuals particularly through contact with poultry litter or through contaminated poultry items. Water may likewise get to be sullied either from poultry facilities or from over the top territory usage of poultry waste. Spillover can convey pathogens from the first site of animal manure-applied agricultural fields to water bodies serving as watering system, drinking, or recreational water sources. Clear knowledge of the transport of pathogens potentially present in poultry wastes and its runoff is essential for the establishment of effective control strategies to reduce the adverse effects on environment, food safety, and public health. A researcher compared two methods of poultry litter application, surface broadcast and subsurface banding, to investigate the influence of application methods on E. coli concentration in runoff from tall fescue pasture. E. coli concentration was found to be significantly higher in runoff from broadcast application than subsurface banding treatment. They inferred that subsurface banding of poultry litter into perennial grassland can incredibly lessen pathogen misfortunes in spillover when contrasted with surface-communicate application. In this manner, the customary surface-communicate use of chicken litter onto agricultural land may bring about large amounts of pathogens on the dirt surface that could be conceivably exchanged to overflow water.

Raw chicken litter has been generally connected to arable area as natural manure or soil correction to enhance the soil fertility and structure. To anticipate conceivable microbiological wellbeing issues for the environment and food crops grown in the field, practical and compelling treatments ought to be created particularly for raw chicken litter preceding area application. Fertilizing the soil, regularly utilized on farms, can inactivate substantial populations of human pathogens; nonetheless, studies have revealed that a few pathogens can survive the treating the soil procedure because of improper composting or cross-contamination. Accordingly, a little population of pathogenic cells may survive or regrow in the completed manure items under favorable conditions. Physical, chemical, and biological treatments can be different ways for pathogen inactivation however may not generally prompt the complete disposal of foodborne pathogens in chicken litter or chicken litter-based natural composts. Furthermore, some cells may become stress-adapted during build-up or composting, which cross-protect them against these subsequent treatments. Based on the hurdle concept, each kind of treatment can be used in combination with other disinfection strategies to potentiate microbial lethality. In order to effectively inactivate pathogens in chicken litter, it would be plausible to design a multi-step treatment with composting as the first step to kill large populations of pathogens, and then apply additional treatments to further eliminate the remaining cells. These systems with multiple treatments involved can be efficient in eliminating pathogens in chicken litter when proper control measures are in place and adopted.

Albeit chicken litter is viewed as a potential wellspring of foodborne pathogens, this doesn’t propose that each part of the litter contains all the different sorts of pathogens that have been accounted for or that they will be available at maximally reported pervasiveness. Regardless, treatment systems ought to in any case be produced to inactivate the most safe and tenacious sorts of pathogens potentially to be experienced. Most of the studies on different techniques have attempted to reduce different bacterial pathogens or indigenous microorganisms in chicken litter or its composted products. Some estimates of pathogen reductions are uncertain and based only on limited lab studies with few pathogens, including indicator microbes (primarily fecal coliforms). However, it is still not clear whether the fate of such fecal indicator bacteria properly represents the responses of various human pathogens. In addition, not all fecal coliforms or tested pathogens emerge from animal feces, and they have some non-fecal ecological sources, which makes it harder to research the destiny of pathogens in animal wastes during different treatments. In this way, future studies ought to concentrate on assessing pathogen survival for various treatments utilizing an extensive variety of conditions regularly experienced during build-up or composting.
