Did Silogerm qualify as animal feed even though its bacilli were not themselves nutrients?

Short answer Yes. California analogized Silogerm to bread yeast because its lactic acid improved silage digestion, reduced spoilage, and increased milk production.

Disclaimer: This is a California State Board of Equalization tax-counsel letter dated February 19, 1952, published by CDTFA as support for a sales and use tax annotation. Its classification depends on the described bacillus culture, lactic-acid action, and silage effects, and it says exemption follows under the same conditions as other animal feed. Another taxpayer should not treat it as binding and should check current Silogerm, bacterial-culture, lactic-acid, silage, digestion, spoilage, feed-additive, exemption, and sales-and-use-tax rules.

Plain-English summary

Silogerm qualified as animal feed under the same conditions as other feed. The product was a bacillus culture that produced lactic acid; although the bacilli were not nutrients themselves, their action inhibited harmful bacteria, reduced silage spoilage, improved digestion, and increased milk production.

Counsel analogized the product to yeast used in bread, which was considered a human-food product.

Gentlemen:
Your letter of January 16 to our Stockton District Office has been referred to us for reply. You inquire whether “silogerm” is exempt as an animal feed. It appears that Silogerm is a culture containing bacilli of a type known to product lactic acid. The bacilli themselves are not nutrients but the lactic acid they produce improves the ensilage by inhibiting the growth of harmful bacterial, reducing spoilage, making the ensilage more easily digested and increasing milk production. We are of the opinion that it is analogous to yeast used in making bread. Such yeast is considered a food product for human consumption. Accordingly, we would regard Silogerm as an animal feed and exempt under the same conditions that other animal feeds are exempt. Very truly yours,

E. H. Stetson
Tax Counsel
