Determination Of Cyanide, Nitrate And Nitrite Contents In Poultry Feeds Of Four Top Animal Feed Companies In Nigeria.
ABSTRACT
The total cyanide, nitrate and nitrite
contents of four Top Animal Feed Companies in Nigeria were evaluated by means
of enzymatic and spectrophotometric methods. Nitrite was determined
spectrophotometrically and nitrate after reduction to nitrite with spongy
cadmium. Enzymatic analysis of the feed samples indicated total cyanide level
ranging between 1.98- 25.74pg/100ml, 1.58-18.22pg/lO0ml, 5.94-13.86pg/lo0ml and
3.56- 78.olpg/100ml for broiler finishers' feed, growers' feed, layers' feed
and broilers starters' feed respectively. Nitrite levels obtained ranged 5.63-
16.88pg/loornl, 5.83-15.00pg/looml, 5.21-13 .75pg/100ml and 5.21- 21.88jig/100ml
for broiler finishers' feed, growers' feed, layers' feed and broiler starters'
feed respectively. These values are higher than the Acceptable Daily Intake
(ADI) allocated by the Joint FAO/WHO which is 0-0.1 mg/kg. Nitrate levels
ranged 3.96-35 .00,ug/lOOml, 16.88-22.9j,zg/100ml, 1.68- 35 .83pg/100rnl and
0.83-28.3 3pg/ 1 DOmi for broiler finishers' feed, growers' feed, layers' feed
and broiler starters' feed respectively. Results obtained were discussed from
nutritional and toxicological points of view.
