Animal feeding stuffs: Methods of sampling and analysis - Detection and enumeration of Bacillus spp. used as feed additive

This document specifies general rules for the enumeration of bacilli in feeding stuffs (additives, premixtures and compound feeds including mineral feeds) [4] that contain bacilli as a single microorganism component or in a mixture with other microorganisms. There are different categories of feed samples:
a)   Additives containing about 1010 colony forming units (CFU)/g;
b)   Premixtures containing about 1011 CFU/kg;
c)   Compound feeds, meal or pellets containing about 109 CFU/kg.

Futtermittel: Probenahme- und Untersuchungsverfahren - Nachweis und Zählung von Bacillus spp. als Futtermittelzusatzstoff

Dieses Dokument legt allgemeine Regeln für die Zählung von Bazillen in Futtermitteln (Zusatzstoffe, Vor-mischungen und Mischfuttermittel einschließlich mineralischer Futtermittel) [4] fest, die Bazillen als einzigen mikrobiellen Bestandteil oder in einem Gemisch mit anderen Mikroorganismen enthalten. Es gibt unter¬schiedliche Kategorien von Futtermittelproben:
a)   Zusatzstoffe, die etwa 1010 koloniebildende Einheiten (KbE)/g enthalten;
b)   Vormischungen, die etwa 1011 KbE/kg enthalten;
c)   Mischfuttermittel, Mehle oder Pellets, die etwa 109 KbE/kg enthalten.

Aliments des animaux: Méthodes d’échantillonnage et d’analyse - Détection et dénombrement des souches de Bacillus spp. utilisées comme additifs pour l’alimentation animale

Le présent document spécifie des règles générales pour le dénombrement des Bacillus présents dans les aliments pour animaux (additifs, prémélanges et aliments composés, y compris les aliments minéraux) [4] qui contiennent des Bacillus comme seul micro-organisme constitutif ou en mélange avec d’autres micro organismes. Il existe différentes catégories d’échantillons d’aliments pour animaux :
a)   les additifs contenant environ 1010 UFC/g (UFC : unités formant colonie) ;
b)   les prémélanges contenant environ 1011 UFC/kg ;
c)   les aliments composés, farines ou granulés contenant environ 109 UFC/kg.

Krma: Metode vzorčenja in analize - Določanje in štetje prisotnih Bacillus spp. uporabljen kot krmni dodatek

Ta evropski standard določa splošna pravila za štetje probiotičnih bacilov v krmi, ki vsebuje bacile (vrste Bacillus) kot posamezen mikroorganizem, komponento ali pomešano z drugimi mikroorganizmi. Ta metoda se ne uporablja za mineralno krmo, ki je opredeljena kot dopolnilna krma, sestavljena predvsem iz mineralov, in vsebuje najmanj 40 % surovega pepela (Direktiva Sveta 79/373/EGS).
Obstajajo različne kategorije vzorcev krme:
a)   dodatki, ki vsebujejo približno 10+10 enot, ki tvorijo kolonije (CFU)/g;
b)   premiksi, ki vsebujejo približno 10+8 CFU/g;
c)   krma, moka ali peleti, ki vsebujejo približno 10+6 CFU/g ter vključujejo popolno krmo in mlečne nadomestke.
Meje zaznavanja so 500 (5 × 10+2) enot, ki tvorijo kolonije na gram (CFU/g). Meje določanja so 2 × 10+4 CFU/g.
