Colostrum Saver PS

Early and adequate intake of high quality colostrum is a very important factor in determining an animal’s health and survival. Maintaining that high quality can be a challenging task. Colostrum Saver PS is a tool to help preserve all the natural immune factors that colostrum offers.

Colostrum Saver PS is a concentrated liquid potassium sorbate that has been stabilized through a patented process to prevent the sorbic acid from oxidizing and losing it’s effectiveness.

Colostrum Saver PS is in a ready to use solution so there is no hassle with mixing or dissolving powders. Just add required amount to colostrum and mix thoroughly.

Bacterial contamination of colostrum can happen even under good management practices. Bacterial pathogens are not only problematic to the animal, they can also interfere with the systemic absorption of Ig molecules. Colostrum Saver PS not only preserves colostrum, it can reduce bacteria counts, and with refrigeration, bacterial counts will remain low. Adding Colostrum Saver PS may also slow the colostrum from fermenting and turning sour.

Colostrum Saver PS has been proven to work up to 96 hours with refrigeration. After this time if the colostrum will not be fed, it may be frozen for later use.

University research has been published in the Journal of Dairy Science showing the benefits of potassium sorbate.

Colostrum Saver PS is an effective and proven tool for maintaining good quality colostrum for calves, foals, lambs and kids
