INTRODUCTION
FOWL CHOLERA
Fowl cholera is a Bacteria disease caused by a gram-negative spore forming bacterium which can affect a wider range of hosts such as Turkeys, Ducks and chicken.
This disease also known as Avian pasteurelosis can affect all age grade of chicken but older birds are more susceptible with a higher incidence recorded among males.
The disease is closely associated with stress of worm infestation which are more prominent in laying birds at the onset of lay to peak production.
Clinical symptoms
The clinical symptoms of this disease may include among others the under listed signs and pathology:
Ataxia and backward retraction of the head
- Emaciation
- Swollen wattle and combs
- Drop in egg production
- Inflammation of joints and hocks
- Jaundiced muscle
Pathology
- Pinpoint hemorrhages in myocardium
- Ruptured Aorta
- Accumulation of peritoneal fat
- Pete heal haemorrhages on adipose tissue
THE CLINICAL AND NUTRITIONAL CHALLENGES OF FOWL CHOLERA TREATMENT
The unique problem in the management of fowl cholera outbreak is the poor response to which a diseased liver can efficiently metabolize drugs and feed ,more so in the enviroment contaminated with mycotoxin and mycotoxin contaminated materials that are used for feed formulation. This situation is more complicated in fowl cholera infection because of additional production of endotoxin by this organism in the host animal
What then should be the role of veterinarians and nutritionist in managing an outbreak of fowl cholera under the above described scenario.
How will the efficiency of immune response to Bacteria vaccination be guaranteed in this environmen
The above statement constitute the multiple challenges facing the Nutritionist and veterinarians in managing fowl cholera outbreaks in the humid tropical climate, as in Africa
Objective
The objective of this case study is to examine the efficiency of a synergistic dietary intervention of Mtox++Mfeed (all are new generation Nano- based toxin binder and Nanobiotic now suitable )in the management of fowl cholera outbreak in a Broiler breeder flock
What is MTox+(AmadeiteR)?
MTox+ is a new generation Nano - based toxin binder, a patented nanotechnology activated Montmorilonite and sea weed extract of Olmix, France,but marketed in Nigeria by Orkila chemicals.
What is Mfeed?
This ia a natural nano alternative, for enhancement of digestion performance in animal feed,containing Amadeite which gives it the catalytic properties that bind the Gram negative bacteria
The products Mtox+ and Mfeed have a wide spectrum of adsorption that can make them bind in a high capacity, like activated carbon to large molecule toxins such as DON,FUMINOSIN and ZEARALININE ,but without binding the vitamins and minerals while Mfeed binds the gram negative bacteria eg Ecli Salmonella and pasteurela organisms.
REPORT FROM FIELD STUDIES IN NIGERIA
FLOCKS HISTORY
The Breeder farm investigated is a medium scale project located in the south west humid tropic of Nigeria
and a Broiler breeder of Hubbard flex that were housed in three flocks of 3a,2b and 1b. All the flocks were raised in the same environment under the same management practice and feeding regime
FLOCK STATISTICS
Table 1 below showed the flock statistics during 8 weeks of investigation of this study.
TABLE 1: FLOCK STASTISTICS
RESULTS
Result of Broiler Breeder performances before and after Mtox + intervention is as shown in the under listed Tables and graphs numbered 3A, 2B and 1B respectively
3A FLOCK INFECTED
HOUSE IB CONTROL
Flocks 3a+2b were severely challenged by an outbreak of pasteurella Multocida(Fowl cholera) which dropped egg production in both houses to 22.355% and 37.82% respectively at 26 weeks of age mortality score on week 26 for both houses stood st 2.6% and 2.68% indicative of high
House 1B the youngest but not yet affected was prophylactically exposed to MTOX+ and Mfeed earlier in the growing stage as shown in the graph 1B
INFECTED HOUSE
INFECTED HOUSE
CONTROL FLOCK
MEDICATION
The flocks had been maintained on a broad spectrum antibiotic which did not show encouraging result on mortality reduction and production increase , such that the 2 affected flocks 3a and 2b experienced very low production of weekly average of 22.3% for House 3a and 37.83% for house 2b at an age when flocks were suppose to approach a steady peak performance,
Flock 1b that was the youngest flock had not exhibited the observed signs of fowl cholera and was proactively managed as a control flock on Mtox++Mfeed intervention in feed at the dosage of 0.5kg/Ton and 1kg/ton respectively to prevent a declining production as exhibited by flocks 3A and 2B
CONTROL+
Mitox++Mfeed was synergistically combined to replace antibiotic medication in flocks 3A+2B but prophylactically administered to flock 1b to check mate the course and spread of the infection to the flock and avoid the drastic drop in production recorded at age 25-26 weeks for houses 3A & 2B (31+2b) Mtox++Mfeed were strategically applied at 0.5kg/Ton and 1kg/Ton at age 23weeks( see tables)
DURATION OF INVESTIGATION 8 WEEK
DISCUSSION
In this report MTox++Mfeed intervention as a, dietary approach in the management of fowl cholera is clearly demonstrated with the use of this new generation Nano products of Olmix, France< marketed in Nigeria by Orkila.
This intervention recognized that the liver is a vulnerable site in the pathogenesis of pasteurellosis due to fatty degeneration and posed limitation to efficient metabolisms of the antibiotics for chemotherapy(rational for using Mfeed). as well as for adequate immune response to Bacteria vaccination because endotixins produced by the organism and exogenous mycotoxin in contaminated feed have been incriminated as possible aetiology for fatty degeneration in fowl cholera epidemics(Adejoro2004)
In the tropics, we have recorded a higher incidence of fowl cholera during the dry season period with more occurrences in layers fed on high energy diet.(Adejoro 2004)
CONCLUSION
In this study MToX++Mfeed intervention had shown that over-reliance on antibiotics chemotherapy may not give a desirable result in an epidemic of fowl cholera. The dietary intervention of MTox++Mfeed had proved very successful in the treatment and control of fowl cholera infection in Broiler breeder
RECOMMENDATION
It is my view that the use of bacteria vaccine as sole prophylaxis may need to be replaced or synergized with a dietary inclusion of the new generation Nano products( Toxin binder in other to present a better and healthier condition for flocks reared in an environment of high mycotoxin induced fowl cholera.
MTox inclusion in the rage of 0.5kg/ton – 2kg/ton will serve useful results in managing and controlling such outbreaks
