Weaner calf producer’s profit comes from selling as many healthy calves as possible, at the highest possible weaning weight and the highest possible price, with the lowest possible input cost.
“What can producers do to achieve a high weaning weight”?
To achieve maximum results, farmers should pay attention to all the following factors:
Zeramec - a unique product
Virbac has made the use of growth stimulant technology in calves easier with the development of Zeramec, a unique patented product.
Zeramec is a combination of a growth stimulant (zeranol) and an anti-parasitic agent (ivermectin) in an injectable formulation.
Zeranol is a semi-synthetic form of estrogen which is ideal for use in young, growing calves under grazing conditions. It stimulates the increased secretion of the calf's natural growth hormone and leads to increased skeletal and muscle growth. Available energy is channelled to skeletal and muscle growth rather than fat deposition.
Ivermectin is a broad spectrum anti-parasitic agent that effectively controls both internal (roundworms) and external parasites (ticks, lice and mites) for maximum growth.
To get maximum results, Zeramec should be applied at a dose of 1ml / 50kg, no longer than 90 days before the expected date of marketing, to calves that are in a positive growth phase, with sufficient high quality grazing and / or supplementation.
Financial benefits: What can Zeramec offer you?
At a minimal 4% increase in weaning weight, this means an extra 8.8kg with weaning at a normal weaning weight of 220kg. At a weaning calf price of R28/kg, this means an extra net income of R222.84 per calf, with a return on investment of 9: 1 (R9 return for every R1 spent) - and that in just 90 days!
Easy to use – it’s a subcutaneous injection that does not require special equipment or specially trained workers to apply the product.
It's fast - two actions in one (deworming and growth hormone), plus no individual time consuming clamping of calves in the neck clamp.
It's effective - it overcomes the problems that can be experienced with traditional implantation, e.g. the formation of abscesses, encapsulation and misalignment / implantation, which may adversely affect its effectiveness. Nationwide trials² have proven Zeramec to be as effective as a zeranol implant and an ivermectin treatment given separately.
