Bio-Mos® is derived from a specific hydrolyzed yeast strain. It supports immune system development, aids in nutrient transfer, enhances digestion, and promotes animal health during stress, making it effective for all growth stages. Backed by extensive research, Bio-Mos boosts overall performance, aiding in feed intake and the opportunity for increased daily gains with reduced cost.

Zinpro® Availa® 4, is built on a unique, patented metal amino acid complex. It provides the highest biological efficacy of any trace mineral product on the market. This means more of the minerals are absorbed by the animal to deliver their full benefit.

Feeding Directions

Provide free choice as a supplement to pasture cattle or cattle in drylot at the rate of one block for each 15 to 25 head. Place in pasture near areas frequented by livestock, such as watering locations, shade or loafing areas. Cattle typically consume 0.75 pound per head daily. Consumption may vary depending on climate, grazing conditions, condition of livestock and or availability of other feeds. In situations where climate and/or other factors result in consumption less than 0.75 pound per head daily, intake of supplement can be increased by providing additional blocks per pasture.

Provide access to fresh water and free choice salt at all times.

If cattle experience excessive stress due to adverse weather conditions, shipping, weaning, or periods of high production, switching to SmartLic® StressLic® Supplement is recommended.

Complexed Minerals

Metal amino acid complexed minerals are absorbed more readily than inorganic trace minerals. Complexes are formed when trace minerals such as zinc, manganese and copper become bonded to a single amino acid. These amino acids serve to transport the minerals across the intestinal wall resulting in optimum absorption. Trace mineral uptake is vital to improve and maintain adequate trace mineral status.

Trace mineral status affect herd reproduction performance and health. Cows consuming balanced, highly bioavailable trace minerals are more likely to produce healthy calves that perform well at weaning. Animals most likely to benefit from complexed trace minerals include cattle experiencing weaning, shipping, adverse weather conditions, or dairy cattle in high production. Stress 22 w/ Bio-Mos with complexed trace minerals is the perfect choice for these cattle.
