Abstract
An assessment for Cd in commercial feed, meat, blood, liver and manure of backyard piggery farms was conducted in two barangays of Nagcarlan. The presence of Cadmium was assayed using AAS-FLAME through an ISO accredited laboratory sampled from commercial diets (n=12), feed ingredients (n=33), edible tissues (n=15) and manure (n=8) in San Francisco and Bucal, Nagcarlan, Laguna ANOVA was accomplished to compare Cd content of the different feed ingredient classifications Pork, blood and liver samples were collected from the public market while samples of feeds and faeces were collected from backyard swine raisers. Feed ingredient samples were solicited voluntarily from three different companies. The results showed that all commercial diets had an average of 0.82 ppm Cd, a level 32x higher than the standard level for man.. The energy (0.40) and protein (0.35) ingredients obtained lower (P<0.05) Cd than vitamin - mineral (5.57) and antioxidant (4.23) feed ingredients. Except for the lone finisher feed, the Cd of pre-starter, starter, grower and breeder feeds were 1.33, 1.13, 0.63 and 0.45 ppm, respectively. The manure of pigs was found to have 0.47 ppm of Cd.
