Dear Dr.Bebek Bandhu Regmi,
Organic Arsenic trace elements are also added in broiler feed in many countries to control intestinal parasite, to improve meat colour, to stimulate growth & to reduce stress. However, activist working for environmental & public health concern are demanding to stop this practice as the residue could chemically transfer into inorganic arsenic which is a known carcinogen.
While arsenic is occurring naturally in your water supply, you should stop adding arsenic if any in your feed formulation.
Did you know that an apple contains 3-5 mg of aluminum & trace amount of lead, arsenic & mercury ? These are good and essential for good health as these trace elements are from organic source but there will be negative consequences if they are from inorganic source.
Arsenic content of water is of course inorganic in nature & it may be very harmful to human if level is more than 50-100 ppb. WHO recommends a limit of 0.01 mg/L (10ppb) of arsenic in drinking water for human consumption? In poultry & animal farms water containing up to 500 ppb is being used in some places due geographical diversity like yours as main source of water supply are from ground water source. What is the arsenic level in your water supply ? If arsenic level is very high in your water system then you must change your water source.
Please remember ! We should always keep in mind that our food supply to public must not contain toxic residual to avoid human health hazards. Thanks, G.K.Dahal

Uses of arsenic preparations/ products are not a common practice in poultry production for control of coccidiosis. The wale fare groups are getting opportunity to speak on broiler and layer production and linking with human health or issues in systematic way and all over world their facts and interpretations are not acceptable for poultry vets. In this case they say residual effect of antibiotics and residual effects of metals like arsenic etc in birds produced for human consumption is posing health hazards to human population. These welfare activists are misinterpreting many issues in the world and they get success in western countries now a days as those developed countries have reached saturation in poultry per capita consumption. It is very simple broiler and layer farmers are always good activities and best for human food. All farmers all over world get good results where they follow strict production standards with ref to feed quality, water quality and air quality. Let us discourage the poultry welfare activists who are bent upon to disturb the poultry industry. All state management should now know what is standard practices and let us adopt poultry standard practices for best health and quality quality control of farm and products . This is possible through quality inputs only. If water quality is poor PH >7-8 then go for treatment of water through any method. If bacterial contains are more take up sanitizer or acidfiers. But every one point has limits . Science is ok. Interpretations are now twisted with business targets. rathm

Dear Mr.Ganesh. Your article on the water quality on poultry farms was very good. I liked your idea of sharing with us information on the compatibility and interactions between many of the commonly used water sanitizers. I have seen many occasions of serious mistakes being made in the using and mixing of such compounds because sometimes we like to be led into the temptation of 'More, the merrier'!! Do you have any information on the use of Bleaching powder and other Chlorine products, especially on the dosage as well as the final residual levels ( ppm) in water that can be safely given to chicken ? Will appreciate if you can kindly find this for me. I am asking you this because there is a lot of controversy on this subject and the levels recommended vary. Regards. Leo Antony

Dear Dr.Leo Antony,
Thanks a lot for your nice comment. Generally in field practices 1.0 ppm of dose is given at source for which 400 gram of Bleaching Powder having approx 30% strength is used to disinfect 1.0 Lakh ltr. of water.
Bleaching Powder {Chemical formula Ca(OCI)2 - Calcium hypochlorite in solid form} should not be added directly in the tank, the solution should be prepared first in 2 ltr. of water & after keeping for 15-20 minutes supernatant should be dissolved in 20 Ltr. of water before mixing in water tank.
In lieu of powder I would recommend Sodium Hypochlorite solution of 9% strength. For 1.0 ppm dose in 1.0 Lakh ltr. of water, 1.1 ltr. is required.
For safety, water should check for residual chlorine with Orthotolidine (O.T.) test method. Residual free chlorine 0.2mg / Ltr is recommended value.
We must remember that Bleaching Powder liberates chlorine which is powerful oxidizing agent & higher ratio affects health of birds and not safe for human consumption also as chlorine may form carcinogens if it comes in contact with organic compounds which are now a day widely used in poultry ration.

I think it is also important to check ph of water as the amount of free chlorine will vary depending on the ph. Ideally, ph should be about 7 or below. This is important if you are using water treatment chemicals that could take the ph up. In this case, if the ph is high a higher dose of tcl well be required

Dear Dr,Kumar,Thank you so much for replying to my query regarding the desirable levels of Chlorine in the drinking water for chicken. I am going to trouble you a little more for some more details such as: 1. Your opinion on adding 40 grams of bleaching powder in 1000 litres of water. What ppm or mg/ of Chlorine level per litre of water will this dosage give? 2. At this dosage,what could be the repercussions on a) Microflora in the gut b) Nutrients, especially the vitamins in the feed c) The epithelium and intestinal tone 3. Can you please elaborate on the likely interactions with certain chemicals about which you have mentioned in your reply.? Thank you very much and I will be looking forward to your reply. Regards. Leo
