Calf RD Formula


  • Calf RD Formula is compatible to mix with milk replacer, milk, or water
  • Adding daily DFMs promotes faster rumen development and encourages starter intakes, both of which allow calves to gain weight more quickly, promotes increased growth rates, and wean earlier if desired
  • Giving Calf RD Formula has been shown to have economic advantages through earlier weaning, earlier breeding and calving, better calf performance, and higher average daily gains



  • Contains concentrated strains of live (viable) bacteria, which have been shown to promote earlier consumption of dry feed and improved growth rate when fed daily
  • Includes digestive enzymes and antioxidants help encourage a healthy immune system
  • Formulated with fermentation products, including live yeast, to enhance weight gain through better gastrointestinal health
  • Specialized protein creates a healthy digestive environment to better withstand the potential impact of pathogens such as clostridia, E.coli, strep, staph and salmonella


Mix one level scoop (4 grams) with the milk, milk replacer or drinking water once daily. Feed Calf RD Formula from Day 1 to Weaning.

For large volume fluid feeding - Mix 200 grams (0.44 pound) of Calf RD Formula with each 50 gallons of milk, milk replacer or drinking water when calves are fed 2 quarts or a half gallon twice a day.

Compatible with colostrum, whole milk, milk replacer and water.

For a calf, the transition to feed can create digestive disturbances and disrupt water and feed intake.  Calf RD formula is specifically designed to aid in the development of the rumen to establish dry feed intake at an earlier age to help improve weaning weight and reduce digestive health issues.  Packed with DFMs (direct-fed microbials), Calf RD Formula uses live bacteria to help maintain a more desirable digestive environment, in turn helping to stave off pathogens and aid in nutrient utilization.

Giving Calf RD Formula is as easy as mixing it with milk replacer, milk, or water.  Adding daily DFMs promotes faster rumen development and encourages starter intakes, both of which allow calves to gain weight more quickly and wean earlier if desired.  Administer Calf RD Formula to create a healthy digestive environment to better withstand the potential impact of pathogens such as E.coli and salmonella.  Calf RD Formula is an effective way to help calves to ease the transition to dry feed with less digestive disruption.



  • To aid in rumen development
  • To improve the transition to dry feed and enhance intake
  • To help reduce digestive disturbances
  • To populate the digestive system with healthy bacteria
  • To help calves to be more viable when moved to a group pen

Calf RD Formula is specifically designed to promote development and a healthier gastro-intestinal tract in pre-weaned calves. Calf RD Formula provides viable enteric lactobacillus, Bifidobacterium, Saccharomyces and other fermentation products.  Through advanced microbiological technologies, probiotic strains of Bacillus are added to enhance animal performance.

Pre-ruminate calves prior to weaning are in a precarious balance for adequate energy to supply growth and health. Typical feeding strategies are energy restrictive when compared to biological potential. Maintaining an optimal gastro-intestinal environment for nutrient utilization is critical for the young calf.

Calf RD Formula contains lactobacillus bacterial strains and other fermentation products that produce lactic acid to maintain optimal intestinal pH levels, provide competitive exclusion of pathogenic bacterial attempting to colonize and createdisease and produce enzymes that aid in nutrient digestion. Calf RD Formula also contains the vitamins of A, D, E and C.

The specially selected probiotic strains of Bacillus organisms have multiple attributes.  The bacillus spores are activated in the intestinal tract and are capable of producingsignificant amounts of amylase and protease enzymes that break down starches and proteins. This active enzyme fortification provides enhanced digestion of the engesta in the young calf’s digestive tract there by promoting improved utilization of nutrients.

Bacillus produce antimicrobial peptides called bacteriocins that kill or inhibit the growth of other bacteria. Is has been demonstrated that Clostridium perfringens, Staphylococcus aureus, E. coli and Streptococcus spp have been susceptible to these bacteriocins. The advantage is that fewer antibiotics are needed to raise calves and this reduces one of the variable input costs of production.

The bacillus organisms remain viable after being shed in the feces. This populating of the environment can reduce morbidity by reducing pathogenic build up in organic material and the enzyme activity in the manure can reduce biofilm formation and lead to easier facility clean up.

The chosen Bacillus strains in Calf RD Formula have consistently shown enhanced animal performance, are non-pathogenic, survive gastric acid passage and activate in the intestinal tract, are genetically stable and do not transfer resistance to pathogenic bacteria.

Calf RD Formula has been designed to be mixed with whole milk, milk replacer or rehydration products.

The feeding rate of Calf RD Formula is 4 grams per calf per day. The product should be fed from birth to weaning. Calf RD Formula can be added to milk products or rehydration products individually per calf or mixed into bulk batches of milk or electrolytes after calculating the correct amount to add.
