Applying the method to premixtures and compound feeds with critical amounts of copper demands a special procedure (see A.2). The document is not applicable to mineral feeds which are defined as complementary feeding stuffs composed mainly of minerals and containing at least 40 % crude ash (Regulation (EC) 767\/2009) [4]. There are different categories of feed samples: a) Additives containing about 1010 colony forming units (CFU)\/g; b) Premixtures containing 1011 CFU\/kg; c) Compound feeds, meal or pellets which contain about 109 CFU\/kg.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>undefined  <\/td>\n<\/tr>\n<tr>\n<td><b>8<b><\/td>\n<td>1 Scope <br \/> 2 Normative references <br \/> 3 Terms and definitions <br \/> 4 Principle  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>5 Diluents and culture media <br \/> 5.1 Diluents  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>5.2 Culture media  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>6 Apparatus  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>7 Sampling <br \/> 8 Preparation of the test sample <br \/> 9 Procedure <br \/> 9.1 Preparation of poured agar plates for spread plate method  <\/td>\n<\/tr>\n<tr>\n<td><b>14<b><\/td>\n<td>9.2 Preparation of culture media for pour plate method <br \/> 9.3 Preparation of the initial suspension and decimal dilutions  <\/td>\n<\/tr>\n<tr>\n<td><b>15<b><\/td>\n<td>9.4 Inoculation and incubation of the plates <br \/> 9.4.1 General <br \/> 9.4.2 Spread plate method  <\/td>\n<\/tr>\n<tr>\n<td><b>16<b><\/td>\n<td>9.4.3 Pour plate method <br \/> 9.5 Enumeration of colonies <br \/> 9.6 Confirmation  <\/td>\n<\/tr>\n<tr>\n<td><b>17<b><\/td>\n<td>10 Expression of results <br \/> 11 Precision <br \/> 11.1 General <br \/> 11.2 Interlaboratory studies  <\/td>\n<\/tr>\n<tr>\n<td><b>18<b><\/td>\n<td>11.3 Repeatability <br \/> 11.4 Reproducibility <br \/> 12 Test report  <\/td>\n<\/tr>\n<tr>\n<td><b>19<b><\/td>\n<td>Annex A (informative)Notes on the procedure <br \/> A.1 General <br \/> A.2 Critical copper concentration  <\/td>\n<\/tr>\n<tr>\n<td><b>20<b><\/td>\n<td>Annex B (informative)Results of the interlaboratory studies <br \/> B.1 Interlaboratory study based on bile aesculin azide agar  <br \/> B.2 Interlaboratory study based on Slanetz and Bartley agar   <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Animal feeding stuffs: Methods of sampling and analysis &#8211; Detection and enumeration of Enterococcus (E. faecium) spp. used as feed additive<\/b><\/p>\n<table class=\"shortdes-table\" style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/bsi\/\"><b>BSI<\/b><\/a><\/td>\n<td>2021<\/td>\n<td>24<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":389379,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2641],"product_tag":[],"class_list":{"0":"post-389371","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-bsi","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/389371","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/389379"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=389371"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=389371"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=389371"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
