Biofilm Management In Poultry

Biofilm Management In Poultry

Water is essential in controlling body temperature, supports the immune system, assist in food digestion, and aids in the processing and elimination of body wastes. Regardless of procurement of water, another concern is contamination of water inside the watering systems through a substance called “BIOFILM. It occurs when bacteria attach to the pipe walls in a drinking system, creating a sticky substrate.

Biofilms are commonly defined as attached bacterial colonies of either single or multiple species, encased in an extracellular matrix.

Biofilms support the survival of bacteria in suboptimal conditions and increase resistance to disinfectants, antimicrobial, and antibiotics. To date, it is estimated that 99% of bacteria can grow in biofilms, and it is suggested that for the majority of bacteria, biofilms are the normal mode of existence.

Plant essential oils like Thyme, Eucalyptol, Clove, Citronella, etc. Have been used for hundreds of years as natural medicines to combat a multitude of pathogens, including bacteria, fungi, and viruses. Several essential oils confer antimicrobial activity by damaging the cell wall and membrane, leading to cell lysis, leakage of cell contents, and inhibition of proton motive force.  In addition, there is evidence that they effectively kill bacteria without promoting the acquisition of resistance.

A blend of all such essential oils is HERBOFLOXIN”-This micro emulsified system;

  • The target zone for Herbofloxin is the gut; it has an antimicrobial effect in the gut due to which there is no biofilm formation.
  • It improves the number of good bacteria in the gut and simultaneously reduces the pathogenic bacteria. This action of Herbofloxin in turn provides a natural growth promoter effect in Poultry.
  • Herbofloxin is freely soluble in water and target species include Salmonella, E. Coli, Campylobacter and Clostridium

5 Tips To Combat Bio Aerosols In Poultry

Combat Bio Aerosols In PoultryAerial pollutants in confined animal houses are widely recognized as detrimental to the respiratory health of animals kept in these facilities. Primary and opportunistic microbial pathogens may directly cause infectious and allergic diseases in farm animals, and chronic exposure to some types of aerial pollutants may exacerbate multi-factorial environmental diseases. The key pollutants recognized in the airspace of livestock buildings are particles, including dust, micro-organisms and their toxins, and gases such as ammonia, carbon dioxide and more than 100 trace gases such as volatile fatty acids. Under commercial production conditions the airborne particles will contain a mixture of biological material from a range of sources, with bacteria, toxins, gases and volatile organic compounds adsorbed to them. Hence, a more descriptive term for these airborne particles is bio-aerosol. Their sizes can range from aerodynamic diameters of 0.5 to 100 µm.

How are bio-aerosols formed?

Under commercial production the airborne particles will contain a mixture of biological material from a range of sources. The chickens produce large amounts of dust as a result of epithelial desquamation, as well as from feed, manure, faeces and litter (Matković et al., 2009). This dust consists of a variety of airborne particles of biological origin, i.e. Bacteria, fungi, endotoxins (lipopolysaccharide, LPS) of Gram-negative bacteria, 1.3-beta-glucan of fungi, fungal spores and mycelium fragments. Hence, a more descriptive term for these airborne particles is bio-aerosol in which the microorganisms can occur either as liquid droplets or as dry particles.

To prevent this problem in poultry, Vinayak Ingredients has introduced a very effective product called “ESSENTIOLITT POULTRY”. Essentiolitt Poultry is a blend of essential oils which works as a poultry sanitizer and reduces the formation of Bio-aerosols. Its features are as below:

  1. 50% reduced respiratory diseases.
  2. It posses potential as natural agents for airborne bacterial activity inhibitors.
  3. They are ecological products for insect pest control.
  4. Reduction in mortality of birds due to severe respiratory problems.
  5. It is acting as a Bio-security in Farms.

Dimension of Water for Poultry Birds

Dimension of Water for Poultry Birds - Vinayak IngredientsWater management is the most critical components in a top-performing broiler flock. In high performing flocks, at around 21˚C, cutting edge broilers by and large will consume 1.8 to 2 times more water than feed, in weight. Water consumption will change, contingent upon ecological temperature, feed quality and bird health:

  1. Water consumption increases by 6% for each expansion in 1˚C between 20-32°C.
  2. Water consumption increases by 5% for each expansion in 1˚C between 32-38°C.
  3. Feed consumption diminishes by 1.23% for each expansion in 1˚C over 20°C.

Any considerable change in water utilization should be researched as this may show a water leak, health issues or feed problem. A drop in water consumption is frequently the primary marker of a flock issue. To assess flock performance legitimately we have to know how much water birds are consuming each day.

Large portions of today’s high performance broilers are being brought up in housing built for the broiler of the past. There are numerous alternatives used to guarantee a water volume/stream will address bird issues at high pinnacle request times. Advanced water meters associated with the house controller can screen water consumption on a 24-hour premise as well as in distributed time increases amid the day. This data can figure out whether our water system is keeping up at basic ‘appeal’ times, as when the lights go ahead after a dull period. Knowing this can be extremely useful in finding performance issues on a ranch, particularly one with huge, multi-houses.

The temperature of the water that birds are drinking should also be considered. The perfect water temperature ought to associate with 10-14˚C originating from the source. Water consumed by the birds should not be over 30˚C. In the event that this happens the drinking system ought to be flushed intermittently to look after cooler, fresher water.

Along with temperature and accessibility the quality of water offered to chickens should be considered for proper growth of Broilers. The quality of water depends on several factors such as the presence of bacteria and other microbes, PH, Level of minerals etc. Disinfectants like Chlorine are widely used in the poultry industry for disinfection of water, but it has many disadvantages such as carcinogenicity, pH dependent activity, highly corrosive and irritating substance. To avoid such problems and to improve performance of broilers Vinayak ingredients has launched an excellent product Herbofloxin which is a blend of essential oils effective as Non- antibiotic growth promoter. It is used to replace disinfectants, antibiotics and acidifier used for growth promotion in water.

MOA of Herbofloxin: – It is a micro emulsion when mixed with a water forms nanoemulsion making it easier to penetrate bacterial cell wall and disrupt it. It is stable at 5 to 45 degree Celsius temperature and has long shelf life.

The advantages of Herbofloxin are as follows:-

  • More than 10% improvement in weight gain
  • Chlorine free meat
  • Pathogen free meat
  • No antibiotic residue
  • Carcass sanitizer
  • Litter improver

Poultry Gut Microbiome

Poultry Gut MicrobiomeThe microbiome of the gastrointestinal (GI) tract of poultry is very diverse yet relatively stable in a dynamic state. The poultry (e.g. duck, chicken and turkey) GI tract consists of cloaca, colon, cecum, small intestines (duodenum, jejunum and ileum), gizzard, proventriculus, crop and esophagus. The GI tract of the poultry is much shorter than that of mammalian animals. But it contains highest bacterial abundance and diversity. The bacteria found in the intestine mostly include Escherichia coli, Lactobacillus, Bacteroids, Eubacterium, Peptostreptococcus, Propionibacterium as predominant organisms. Other group of micro organisms such as anaerobic, gram-negative cocci, facultative anaerobic cocci and streptococci are also found in the GI tract. In this article we briefly discuss the factors affecting the poultry gut micro biome and its importance for poultry nutrition.

Microbiome and Host

Many intestinal bacteria hydrolyze carbohydrates to simple sugars which are further fermented to short chain fatty acids (SCFA) (viz., butyrate, propionate and acetate) by other intestinal bacteria. The SCFA are utilized as a source of energy and carbon. Gut bacteria also contribute to host nitrogen metabolism. These bacteria metabolize uric acid to NH3, which is utilized by the host to synthesize a few amino acids such as glutamine. Gut micro biome of poultry may also serve as a source of vitamin to its host. Mucins secreted by goblet cells of the gut are important source of carbon, nitrogen and energy for some commensal and pathogenic bacteria. Gut micro biome also has impact on intestinal morphology of poultry. One such effect is evident when birds raised on a conventional diet show shorter intestinal villi and shallow crypts with low load of bacteria. However, dietary supplementation of probiotic organisms increases villus height: crypt depth ratio in ileum of broilers.

Microbiome and Immunity

The first line of defense mechanism in the inner surface of avian gut is the gel-like mucus layer formed from mucin glycoprotein produced by the goblet cells. The mucus layer prevents the intestinal pathogens from penetrating into intestinal epithelium. The disruption of the mucus layer is probably due to the severe necrosis of the intestinal mucosa which results in vast shedding of goblet cells. Production of beta-defensin is another important strategy present on the intestinal epithelial surface. Βeta-defensin are produced by avian macrophage, heterophils and epithelial cells that kills various intestinal pathogens by disrupting cell membrane permeability. In birds, the cell mediated immunity (T and B cells) can be found in dispersed areas (lamina propria and epithelium) and in more organized lymphoid tissues (Payer’s patches and bursa of fabricius).

Microbiome and Diet

Diet has great potential to modulate the host digestion and nutrient absorption. Wheat, barley or rye-based diets have more impact on the gut micro biome. These diets contain high levels of water-soluble, indigestible, non-starch polysaccharide that favor necrotic enteritis. Excessive non-starch polysaccharide leads to rise in digesta viscosity, decreased digesta passage rate and a decline in nutrient digestibility. Another potential diet ingredient, soyabean is used as a source of protein to promote the growth lactobacilli population and reduce the number of coliforms in cecum of poultry. Some of the gut micro organisms are also influenced by dietary fat source. Dietary enzymes such as xylanase and beta-glucanase, increase intestinal lactic acid bacteria

(LAB) and decrease the population of adverse and pathogenic bacteria such as E. coli. Dietary supplementation with xylanase and beta-glucanase protects against necrotic enteritis as the enzyme breakdown the non starch polysaccharide in the diet and reduce the digesta viscosity. Plant derived trans-cinnamaldehyde and eugenol are effective in reducing S. enteritis colonization in 20-d old broiler chickens. Others such as blend of essential oils, containing thymol, carvacrol, eugenol, curcumin and piperin reduce the colonization and proliferation of such pathogens. Antibiotic growth promoter (AGP) is another feed additive used to improve feed efficiency, increase animal growth and maintain animal health. The inclusion of AGP in poultry diet reduces the incidence of disease and promotes better performance of the birds by inhibiting the growth of enteric pathogens. However, due to rising antibiotic resistance among the pathogens, the use of AGP has been prohibited. The proliferation of the bacteria present in the gut can be increased by the ingestion of prebiotics.

Prebiotics are polysaccharides such as galatosaccharide (GOS) and fructosaccharide (FOS).

GOS favors the growth of Bifidobacteria in the GI tract of broiler chicken.

Competition for nutrient and attachment site

The GI tract of newly hatched chick is sterile, but is immediately colonized by surrounding organisms. Over the period of time, normal colonization and succession of gut micro biome takes place in healthy adult poultry’s intestine. The GI tract serves as an ideal habitat for micro organisms however, due to limited space and resources; there is competition among organisms for nutrient resources. Some bacteria produce bacteriostatic or bactericidal substances to kill its competitors. The LAB ferment carbohydrates to organic acids and inhibits the growth of certain pathogens such as E. coli and Salmonella by reducing the pH of the gut. Certain bacteria such as Enterococcus sp., Pediococcus sps., Bacillus subtilis also produce antimicrobial agent called bacteriocins to selectively inhibit the growth of other bacteria. However, pathogens are adapted to new environment very fast mediated by a process such as conjugation, transformation and transduction. Providing probiotics (live microbial feed supplement) benefits the host through the following mechanisms: (1) inhibiting the growth of pathogenic bacteria from colonizing and proliferating in the gut through competition for nutrient and attachment site (2) production of bacteriostatic and bactericidal substances against pathogens (3) enhancing gut barrier function and (4) enhancing host immunity.

Poultry litter microorganisms influence gut microbiome

Chickens are in constant contact with the micro organisms from the surrounding environment. The poultry litter usually harbors a complex microbial community. Reuse of poultry litter commonly practiced by poultry farmers to reduce produce cost, influences chicken guts micro biome. The reused litter may also harbor disease-causing micro organisms from the previous flock and thus serves as a source of pathogens to the subsequent flock.

Conclusion

The gut represents an essential microbial ecosystem that lives in symbiosis with the host. The development of GI micro biome plays a crucial role in the nutrition, health and growth of the chicken. Thus further research on the intestinal micro biome of the poultry can potentially provide us more knowledge to improve management of poultry diseases, antibiotic resistance and better control of colonization and spread of human pathogens.

Changing Trends in Antibiotic Use in the Poultry Industry

Changing Trends in Antibiotic Use in the Poultry IndustryA major feature of poultry production nowadays is the reduction of in use of antibiotics as growth promoters, and this is majorly due to concerns over bacterial resistance.

Antibiotics used in a widespread manner as a feed additive can lead to development of Bacterial resistance as the residual antibiotics in the tissues of poultry can be consumed by humans. The bacteria resistant to antimicrobials may also get transferred from one individual to another individual leading to reduced performance of antimicrobials in humans.  This prompted the WHO in 1997 and the Economic and Social Committee of the European Union in 1998 to conclude that the use of antimicrobials in poultry could be a possible risk for the general health and well being of humans.

Many organisations are focusing their research on the development of alternative strategies to maintain the gut health of poultry and enhance performance of poultry by using various other substances, commonly known as natural growth promoters (NGPs). These Natural Growth Promoters have been identified as effective alternatives to antibiotics. A good popularity has been gained by Phytobiotics as NGPs especially, due to their beneficial effect on gut health, performance of birds and positive effects on the immunity of the bird.

Phytobiotics can be defined as plant derived products added to feed in order to improve performance. They originate from leaves, roots, tubers or fruits of herbs, spices and other plants. Phytobiotics are basically of plant origin, and popular extracts that are gaining interest among researchers and poultry producers are thyme, oregano, turmeric and garlic.

Keeping in mind the changing trends in the market, Vinayak Ingredients launched a natural growth promoter by the brand name Herbofloxin. Herbofloxin maintains the health of the gut and as an alternative to antibiotics. It has phyto-constituents of antibacterial nature that target the gut pathogens including important zoonotic bacteria. As a result, Herbofloxin promotes the growth of commensals.

Herbofloxin provides immune-modulator effect which improves tolerance to pathogenic bacteria and improves gastrointestinal micro-climate so as to improve the digestibility and uptake of nutrients. All these results almost nullify the requirement of antibiotics making it as an effective natural antimicrobial growth promoter.
