    MAREKS AND SOME FACTS
    bY GLENDA l. HEYWOOD

    Fanciers please check the site that the mississippi state has on diseases. here is the URL
    http://www.msstate.edu/dept/poultry/dislist.htm
    then click on the various classifications. It is not always as we think when the birds are sick.
    This Mareks virus is aggrivated and caused by high heat and severe cold and the chicken generally young or just before laying in pullets or really old birds will come down with the Mareks. Stress is a high factor in bringing on the Mareks virus.

    Such as
    there is a theory that if a young white turkey is hatched and raised with sebrights it will cause the sebrights to have a automatic immunity to the mareks. You see turkeys have this strain in their bodies and also when making vaccine the turkey mareks vaccine is
    a live vaccine,where as they make the chicken vaccine out of killed vaccine.

    Also if you need any information on the use and making of vaccines you can dial up the chemist [email protected]
    very nice man who is in the business and knows his stuff on this.

    LYMPHOID LEUKOSIS
    Also there is Lymphoid Leukosis which is a disease of adult chickens- and turkeys and game birds. this virus is transmitted out of the body by infected birds via eggs and feces. Also by blood sucking parasites or if the person is vaccinating for fowl pox it will be on
    the needle transfered to the next chicken

    It makes lymphoid tumors in the liver and spleen. Also the visceral organs such as ovary and lungs. the birds may appear healthy but will have loss of appetite, progressive emaciations and diarrhea generally soon after onset of laying, but will continue to plaque you as long as the flock is maintained on your place. One needs to have a flock that is resistant to this. Also brood in isolation not mixing age differences, thru 6 weeks of age.
    Keep incubator clean and disinfected,

    Good care and limited stress ( this is important in mareks as it is a disease caused by stress, if the nervous system is not stable in the bird) also adequate rations at all times for the birds, going with out feed and water is stressful to the birds.

    VISCERAL MAREKS
    this is generally on young birds but older birds can be affected also.As stated is is a herpes virus; the feather folicles and dander, are what gives this disease to others. the infected bird sluffing off mareks feather folicles. also dander is shed. The disease has a long life in some chicken houses for many months, even up to a year.

    The clinical symtoms is faster with visceral than lymphoid mareks. And incubation is short.All mareks types are lymphoid in character. visceral, ocular, skin, or combinations of all.

    Visceral is in lessions of the skin and in broilers a lot.Seen in gonads, liver, spleen, kidneys, and heart, lungs and muscles. Birds dying with internal masive tumors.

    The neural type is the paralysis of wings, legs and neck. loss of body weight and anemia, labored respiration, and diarrhea are common symptoms. Ocular or grey eye as it is called, seen in early maturity but will live longer than the others,

    Characterized by spotty depigmentations of diffused greying of the iris of the eye. Pupil developsan irregular shape and fails to react to light. emaciation diarrhea and death follows.

    There is no treatment for either type of mareks. Only if you choose vaccine and it is only 90% effective when used.You have to VACCINATE with in 1 day out of incubator
    So 10% of the vaccinated chicks done as day olds will be not immuned from the vaccine.
    As they did not accept the vaccine

    SOME OTHER THINGS THAT MAY SPREAD DISEASE

    LICE AND MITES
    control all blood sucking parasites ( this is done by taking 1 qt of clean car oil and 1 qt kereosene and take a paint bruch and paint the roost poles and the wooden areas and cracks of the building where the parasites live and breed in dark places. doing so at the beginning of the day and running the flock out of the building and if you can't do this, at least use a screen door screen in front of the open door and leave windows open for ventilation.) the birds will not die but at night close the door. ha ve done it many times
    as I used to do this at leat every two months. parasites cause more infection of birds than what one thinks.

    RATS AND MICE
    Same with rats and mice, if they inhabit your buildings ans eat and drink from the feeders and waterers this cause much disease and stress on the bird. You should have the rat bait boxes in the buildings. Take a strong box with lid and on the side of the box 2 inches above the bottom cut a hole the size of a 50 cent piece and in side put several sacks
    of rat bait, cutting the ends off the sack no need to spread out, as these varmints like to steal their food.
    Now secure the top on so the birds or kids can't get it off and set in the hen ouse, chick house, that shed, under the house in the basement etc where ever the rats and mice live. Rats a family of six will eat over 8-50 lbs bags of feed a year. Plus leave you there manure and urine. All the things needed to make chickens and humans sick.Fill new rat bait sacks every two weeks, also vary the brand name of the rat bait. Remember a average rat takes and stores the rat bait for almost a week before it eats enough to kill it.

    And old saying if you see one rat or mice you have a hundred is true. Besure and burn all sacks, lumber and get rid of those old tires. Rats and mice love to live in them and breed in them.

    I have rat bait boxes. I made them myself and they work great.

    Great post. [​IMG]

    I'm not farmiliar how to do this
    I will try and see what this means

    thanks for your kind words
    I enjoy helping people make good decissions with chickens and their care

    I raised many decades chicks as we hatched 3500 a yr
    and kept 150-175 for breeders each yr
    I had purebred Cochins, cochin frizzles, modern games and cornish all bantams and bantam ducks
    All hatched with a Leahy incubator
    brooded in large brown wheaties boxes
    gotten from our grocery store
    but raised lots of large fowl breeds also

    Puget Sound Baby!
    Yes, thank you for your informative posts. I will check out that website. Is it ever too late to vaccinate for Mareks?

    yes mareks is in every chicken and they carry the genes for it
    but if vaccinated they need it done on day taken out of incubator
    thus the biosecurity of the whole place you have your birds in incubator and brooding needs to NOT have any one else maybe bringing germs that might be mareks

    the is no problem with the mareks vaccinated birds being included with unvaccinated birds
    they DO NOT give mareks if vaccinated
    only the chick that didn' take the vaccine
    it can give off mareks dander to other birds not vaccinated
