This article discusses the significant health threats to Australian beef and dairy cattle, including nutritional imbalances, infectious diseases, and parasites, which impact growth, fertility, and overall productivity. Virbac's Target Beef and Target Dairy programs aim to address these issues through integrated solutions offering comprehensive protection with a focus on improving health, productivity, and return on investment.
Nutritional imbalances, infectious diseases and parasites are the key animal health threats affecting the health and productivity of Australian beef and dairy cattle. Cattle farmers want preventative programs that effectively protect health and productivity, are convenient to implement and deliver a sound return on investment. Virbac’s Target Beef and Target Dairy programs were developed to meet these expectations. Let’s examine the critical animal health threats to Australian cattle and available solutions.
KEY POINTS
The threats beef and dairy cattle face are interrelated; for example, cattle with nutritional imbalances are more prone to parasites and disease. It makes sense to deliver simultaneous and targeted solutions to these threats.
Nutrition
Nutritional imbalances are common in grazing livestock and can include suboptimal levels of energy, protein, macrominerals (e.g. calcium, magnesium, phosphorus), trace minerals (e.g. zinc, copper, selenium, manganese) and or vitamins (e.g. A, D, E, and B12). Nutritional imbalances will lead to suboptimal growth and fertility because cattle lack the ‘building blocks’ to grow and reproduce. Nutritional imbalances will also increase the risk of cattle being more prone to infectious diseases and parasites.
Multimin Evolution is a unique trace mineral injection for cattle containing zinc, copper, selenium, and manganese, and it has been shown to increase productivity by improving fertility and immunity. 1-20
Infectious Diseases
Infectious disease involves a wide range of germs that can cause scours, pneumonia, lameness, abortions and even death. Cattle are more likely to succumb to these illnesses when exposed to stressful environmental and management conditions (e.g. poor nutrition, transport, drought, flood, high stocking rate, heat stress) and under periods of increased metabolic demands (e.g. weaning, joining and calving).21
Infectious diseases can directly impact productivity due to sickness or death. Productivity is also lost because cattle exposed to germs or infections are forced to use nutrients to support their immune response rather than for growth and fertility. In this way, infectious diseases can significantly and indirectly impact productivity. Clostridial diseases (e.g. tetanus, pulpy kidney, botulism, black leg and black disease) occur too rapidly for cattle to protect themselves, and vaccination is essential.22
Websters® 5 in 1 B12, Websters ® 7 in 1, and SingVac® are trusted solutions to prevent economic losses due to infectious diseases from clostridial germs and leptospirosis.
Parasites
Parasites are found inside (e.g. worms, fluke) and on the skin of cattle (e.g. ticks, lice and flies). Young and adult cattle with infectious diseases and/or nutritional imbalances are more prone to parasites. Parasites directly lead to productivity losses by suppressing appetite and taking blood or nutrients, which can lead to nutrient imbalances. Importantly, they also affect productivity because uncontrolled parasite burdens force cattle to use their immune system against the parasites at a loss to potential growth and productivity. Unfortunately, many parasites of cattle are difficult to control due to chemical resistance and constant re-exposure to new parasite burdens from the paddock.23,24
Cydectin Platinum, a dual active combination drench and Cydectin Long Acting, a high concentration injection, are trusted solutions, highly effective against resistant worms with persistent activity reducing pasture contamination.
Target Beef and Target Dairy - Key Programs to Improve Productivity
Nutritional imbalances, infectious diseases, and parasites are interconnected threats to the health and productivity of cattle. Therefore, it is unsurprising that the best preventative animal health programs simultaneously address all these critical threats.
The Target Programs, developed by Virbac, include the concurrent use of Multimin Evolution, Websters vaccines and the Cydectin drench range. For example, young cattle treatments in southern dairy and beef would consist of:
Websters 5 in 1 B12 is ideal for purchased steers or as a booster before high-risk periods. Singvac is added to programs where botulism is a risk. Using Cydectin Long Acting to beat the spring rise is critical in cattle tick regions. Multimin Evolution, Websters 7 in 1 and Cydectin Platinum are ideal pre-calving treatments for beef or dairy cows. All these products can also be used in lactating cows✝ with Cydectin Platinum recently approved with a Nil Milk withholding period.
Multimin Evolution optimises immunity & fertility. Multimin has been shown to improve first-cycle conception rates by up to 19.4 %, increase pregnancy rates by up to 12% in cows 11-16, and improve sperm quality in bulls. 17-20
Websters vaccines fast-track protection against infectious diseases the immune system cannot protect against fast enough. Producers can choose Websters 7 in 1 for breeders and Websters 5 in 1 B12 for non-breeding stock. When Multimin Evolution is given on the same day as a vaccine, cattle can develop enhanced protection against the diseases covered by the vaccine and improve their general health to help fight off infections. 1,5-10
Cydectin Platinum ensures 99-100% removal of worms and prevents pasture contamination for up to 35 days. 25,26 Cydectin Long Acting can provide season-long protection against key worms of Ostertagia (112 days) and Barbers Pole Worm (120 days), and at least 65 days of prevention of cattle tick eggs, breaking the cattle tick life cycle and keeping the pastures cleaner for longer.27 These treatments allow the immune system to have a ‘break from fighting parasites, and cattle can focus on growing and staying healthy and fertile. Producers can choose between these treatments based on preferred ESI and application methods.
An effective drench, such as Cydectin Platinum, has been shown to increase productivity (weight gain) compared to single active drenches such as Dectomax. In a trial involving 345 weaners over 63 days, Cydectin Platinum-treated cattle grew an additional 8kg compared to Dectomax-treated cattle.26
It makes sense to give these animal health treatments concurrently on the same day, offering the following benefits:
Many farmers ask, ‘Can I administer a drench and vaccine on the same day?’. While different products should not be mixed before administration, all products included in the Target Beef and Target Dairy programs can be given simultaneously*. Administering Multimin Evolution, a drench, and a vaccine on the same day provides the ultimate holistic approach to animal health, leading to more productive animals.
*Good injection practice recommends that multiple injections be given on opposite sides of the neck or at least one hand width apart. Multimin Evolution can be administered concurrently with other animal health products. If in doubt, consult your veterinarian. DO NOT MIX products with Multimin Evolution in the same syringe prior to administration. Do not use it concurrently with drenches, boluses, or other animal health products containing Se or Cu.
