Foreword
All technical contents of this Standard are mandatory.
This Standard is a modification and supplement to GB 13078-1991 Hygienical
standards for feeds.
Compared with GB 13078-1991, the main technical differences in this Standard
are as follows.
- according to the objective needs of feed products, it allowed an increase
of amount of indicators of chromium in the feed, feed additives;
- added a supplementary provision on arsenic tolerance indicator in feed
additives and pig, poultry feed premix feed and concentrate feed, cattle,
sheep concentrate supplement products; modified the permissible amount
of arsenic in phosphate products from 10 mg/kg to 20 mg/kg;
- added a supplementary provision on the allowable amount of lead in duck
compound feed, bovine concentrate supplement, chicken, pig
concentrated feed, bone powder, meat and bone powder, chicken and pig
compound premix;
- modified the permissible amount of fluorine in dicalcium phosphate
products from 2000 mg per kilograms to 1800 mg per kilograms; added a
supplementary provision on the allowable amount of fluorine in bone
powder, meat and bone powder, duck feed, cattle concentrate supplement,
pig, poultry additives premixed feed, laying hen, pig, poultry concentrated
feed products;
- added a supplementary provision on the allowable amount of mold in
bean cake (dregs), rapeseed cake (dregs), fish powder, meat and bone
powder, pig, chicken, duck feed, pig, chicken concentrated feed, bovine
feed supplement material products;
- in aflatoxin B1 health indicators, broiler feed is divided into pre-feed and
later feed of which the allowable values were respectively revised to 10
µg and 20 µg per kilograms of feed; added a supplementary provision on
he allowable amount of aflatoxin B1 in cottonseed cake (dregs), rapeseed
cake (dregs), bean dregs, piglet, pig feed and concentrated feed, chick
compound feed, chick, chicken, growing chicken, laying hen concentrated
feed, duck feed and concentrated feed, quail compound feed and
concentrated feed, bovine feed supplement materials;
- added a supplementary provision on test methods for health indicators.
