Kerry Farmer Robert Costello says using Velibol and Metrabol on his farm has been GAME CHANGING
Here is the science and facts behind his comments on
Velibol
* Easier Calving - due to better uterine dilation and contractions, with 23% more calving without intervention
* Transition - due to a less stressful calving, cows transition into milk better and return to cycle 6 days quicker
* Colostrum Quality - Velibol contains Selenium and Vitamin E, essential antioxidants, protecting immune cells, Zinc, for producing immunoglobulins, Copper, for immune function, and Vitamin D, for immune strength. Calves are born without an active immune system, relying almost entirely on absorption of antibodies from colostrum. High quality colostrum is defined as being over 22% on Brix refractometer. 28 - 30% on the Brix, signifies excellent, high quality and nutrient dense colostrum, with an antibody concentration of roughly 100g/l. Boosting colostrum quality, boosts calf vitality.
Metrabol
* Fertility - 11% improvement in conception at first AI
* Cycling within a few weeks - 44% increase on cows cycling at 30 DIM.
* Uterus Cleaning - a clean uterus, reduces the presence of infections, which can delay the cow's return to cycling, reduce milk production and increase culling rates.
