Malaysia battles fly breeding in poultry houses

In Malaysia an influx of flies have begun appearing as the onset of the wet season begins, leading some locals to blame nearby poultry facilities.

The problem has been blamed on the “open concept poultry farming” practised by some businesses. Although new investors must use a closed farming concept, existing farmers have been given time to gradually move to the closed farming concept.

Fly breeding occurs when the poultry droppings are wet and not when it is kept dry. Poultry droppings can get wet due to rain beating into the open poultry sheds, from leaking poultry drinking water containers or drinking nipples. They can also be caused by excessive moisture in the dropping itself.

To prevent this the floor of the poultry shed should be cemented for easy cleaning. Secondly, the roof of the sheds should be extended sufficiently on both sides to prevent rain water beating into the sheds and wetting the poultry litter (poultry manure/poultry droppings). Thirdly, a layer of sawdust should be spread daily over the poultry droppings to absorb excessive moisture in the droppings to keep them dry.

    Fly problems are every where.I have seen this during my travels in India, Bangladesh etc and have recommended proper measures through effective biosecurity and through feed.
    Competition in feed is great in malaysia and competitiors often use this as a point that a particular feed when used haev no fly problems.Why? because certain banned products are used through the feed to control the same.Effective biosecurity, proper measures through feed and effective enforcement of the rule and regulations are the major factors to control the problem.Who is to look after this? Problems of flies is seasonal they come and go and if we dont take proper measures either through biosecurity or through feed we will have to live with it just like haze which engulfes the whole Asean every year.

    although I have given my comments earlier I wish to add a few more points.Most of the problems related to flies in the farm here are due to--
    Excessive usage of meat and bone meal in the feed where the flies are attracted to the smell of the feed and also usage of fish meal and other source of animal proteins.
    When fly control measures are adopted it is not done in the right way in the farm. Some use various forms of sugar coated snippets where the adult flies are attracted and they after eating it die off leaving the larvae untouched. In some case various forms of sprays are used without clearing all the faecal materials and this is also not effective. The best way to control this menace is to have a proper schedule of spraying at every batch of production say broilers by clearing off all faecal materials and then do the spraying with a good fly killer available in the market. The choice of the product must be able to kill the adult flies as well as the larvae. In one year at least a schedule of three to four time has to be arranged for the spraying. If possible people who are engaged in pest control has to be consulted. Raw materials has to be properly checked especially of animal origin for any form of decaying,bad smell etc. If mollasses is used in the feed mill for cattle feed production additional procedures has to be taken for proper storage and no spillage should take place as this will attract the flies also.
    All the faecal materials after being cleared should be dried and properly incinerated to kill all living flies and larvae and properly disposed off or used as fertilisers.
    There are quite a number of fly repellents available but this will again kill only adult flies and repell them and they will continue to multiply in hot weather.
    Biosecurity is a total insurance policy for the flock and you will have to adhere to--
    Proper schedule of spraying
    Cleaning and proper incineration of all faecal materials including dead birds etc.
    Sprayer used should be able to kill adult flies as well as the larvae.
    Measures can be taken through the feed if allowaed in some countries through usage of some chemicals like-CYROMAZINE
    which you can make a 2% concentration and use it at 500 grams per ton of feed and this has been found to very effective in some areas as per my observation.
    Farmers has to be thought the damages that flies can bring in to the farm such as carriers of virus, bacteira etc, and they should be told the right method of controlling and eradictation.
    It is not an easy task--feed millers has to be involved--pest control personnels--Veterinarians who advise the farmers--Suppliers of chemicals and sprayers--and above all good animal husbandry practices--good feeding practices and good biosecurity which will have to be revised from time to time to achieve good results.It is a combined effort by all.
