Methods for maintaining and administering live probiotic as feed additives for animals
First Claim
1. A method for administering live probiotic bacteria to a population of animals at an animal feedlot, comprising:
- (a) preparing a concentrated aqueous suspension of live probiotic bacteria;
(b) establishing and maintaining uniformity of the concentrated aqueous suspension;
(c) controlling the temperature of the concentrated aqueous suspension within a temperature range that inhibits growth and multiplication of the bacteria in said suspension without killing the bacteria;
(d) adding at least a portion of the concentrated aqueous suspension to an aqueous diluent liquid to form a dilute aqueous suspension of the bacteria;
(e) mixing the dilute aqueous suspension with a ration of animals feed to form bacteria-supplemented animal feed; and
(f) presenting the bacteria-supplemented animal feed to the animals for consumption.

Abstract
Methods for maintaining and for preparing at a livestock feedlot a concentrated suspension of bacteria at a known, accurate concentration and for storing the prepared suspension for prolonged periods at the feedlot in a ready-to-use condition without significant loss of viability, allowing feedlot operators to conveniently administer such bacterial supplements to large numbers of livestock as a probiotic on a regular basis in accurate dosages. The method of administering the bacterial supplements includes, an insulated liquid-holding vessel cooled by refrigeration appliance, and mixing and recirculating appliances to ensure temperature and concentration homogeneity of the bacterial suspension. The vessel and contents are gravimetrically monitored to ensure accuracy of bacterial concentration. In each of several embodiments, at time of intended use, a preselected mass or volume of bacterial liquid suspension is dispensed on demand from the vessel into a separate mixing tank for further accurate dilution and for addition of other microingredients to the suspension, as required, immediately before adding to and mixing with a known mass or volume of animal feed. The methods can be used with or without a separate microingredient weighing or volumetric metering system.
