We all know drench resistance is now widespread on New Zealand sheep properties. While drenches remain an important tool, long-term parasite control and farm profitability increasingly depend on nutrition, grazing management, and the strategic use of forage crops. When used well, forage crops not only reduce worm challenge but also significantly lift lamb growth rates […]

Vetlife veterinarians have been testing bulls for breeding soundness for some years now, using jump tests and/or semen analysis under the microscope following electroejaculation. To advance our capabilities at Vetlife, we have recently purchased an iSperm machine. This cutting-edge device analyses sperm motility using a computer-assisted programme. Not only can iSperm assess bulls, but it […]

Antimicrobial resistance (AMR) is one of the top global public health and development threats identified by the World Health Organisation. It is estimated that bacterial AMR was directly responsible for 1.27 million global deaths in 2019 and contributed to 4.95 million deaths(1). By now most farmers will be familiar with the traffic light classification of […]

The number of newborn lambs that survive to weaning is the single biggest driver of profitability on most sheep farms in NZ (fine wool farms being the obvious exception). Yet, so often, we leave the outcome to chance, and we fail to protect our investment by neglecting to use the very good available sheep performance […]

Managing Beef Cows Before and After Mating Getting cows in calf early and in good numbers is one of the strongest drivers of profitability in a beef herd. Two key performance goals are high pregnancy rates and a tight calving spread, both of which depend on how cows are managed in the weeks before and […]

Pain relief in sheep has been front of mind this year, with a focus on treating both shearing cuts and lambs at tailing. Reducing pain is great for welfare, but it also makes economic sense when it allows animals to return to normal behaviour in less time. Each season we are getting more information about […]

Bionic Plus CRCs are back after being unavailable for the last couple of lambings. For some sheep farmers, this absence removed an important tool from the toolbox for managing the effects of parasitism. Many of these farmers filled the void with persistent anthelmintic injections, e.g. Exodus LA, but a productive and sustainable sheep-breeding and lamb-growing […]

While much attention is given to the health and fertility of cows, the breeding bull is equally crucial in minimising the empty rate in the dairy herd. Thinking of the seasons where you have had unexplained poor heifer in-calf rates or a high empty rate following a good 6-week in-calf rate, it is more than […]

Think Johne’s disease, think cattle? Think again! Johne’s disease is a bacterial infection resulting in untreatable wasting and death of adult animals. It is a challenging disease to control due to its very long incubation period, poor test accuracy and long environmental survival. This has implications for disease management and means our only realistic target […]

Bionic Plus® sheep capsules will again be available for the 2025 season. Bionic capsules were removed from the market, along with all other controlled release capsules, as part of a requirement by the regulatory body, the ACVM, following some variabilities being detected in some products. Bionic Plus has since undergone rigorous testing to show its […]

Weaning can be a stressful time for young cattle. It is important that we minimise the stress of transition, focus on keeping daily growth rates on track, and ensure animal health is a priority. Weaning is also a convenient time to administer preventative animal health treatments going into winter. We are talking about worms, trace elements, and […]

In ruminants, cobalt is needed for rumen microbes to make vitamin B12, which is required for the formation of glucose and amino acids. Cobalt or B12 deficiency impacts energy and protein metabolism, causing a starvation of sorts. Clinical signs of deficiency include anorexia, poor growth rates and ill-thrift. These signs could easily go unnoticed or […]
