Grass supplies

Grass is in abundant supply on farms at the moment and it’s presenting some challenges. On some farms with very heavy covers it won’t be possible to graze silage fields at this stage and get around the rest of the grazing paddocks. On Tullamore farm the average farm cover is at 968kg/DM/ha and 40 acres of silage fields have been closed this week in a bid to lift demand in line with expected growth over the next few weeks. The plan is that this silage would be cut in the first week of May as a high-quality cut for feeding weanlings and ewes pre-lambing next winter. Grazed paddocks on Tullamore are hitting growths of 40kg/DM/day, while the heavy covers have stalled in terms of growth. With good weather forecast this week, it’s an ideal chance to get slurry and fertiliser out to get grass growing. You also need to maximise the number of animals outdoors while you can, to get grass grazed and stimulate growth. Make a point of walking all your fields at the weekend to assess what grass you have available. You’ll be surprised how much you have. More importantly, take action by getting stock out.

Castration

With the current market for bull beef in a difficult place, some farmers are looking at castration to maximise selling options in 2019. It’s important to get it right, because if completed incorrectly it can result in sick animals and will affect thrive for a prolonged period. One of the most important points is that it is illegal to castrate calves over six months without using local anaesthetic. Good hygiene is essential to minimise the risk of infection, especially after surgical castration. It is best to castrate calves as young as possible, less than six months of age. You should administer a clostridial vaccination to protect against tetanus when using banding or the rubber ring method. Try to provide a clean, dry environment with adequate space for movement to relieve stiffness for calves after castration. Outdoors is the best option at this stage of the year. Inspect and monitor calves closely for two weeks after castration. With latex bands the scrotum should drop off within four weeks of castration. Look for swelling, signs of infection, tetanus and abnormalities. Treat wounds as needed. Seek professional advice/help from a vet sooner rather than later if calves show signs of severe pain, swelling or infection.

ClosAmectin and Closivet withdrawal changes

Norbrook® Laboratories Ltd has issued an extension to the withdrawal period for its combination ivermectin and closantel endectocide products, Closamectin and Closivet pour-on solutions for cattle. The product is now subject to a withdrawal period of 58 days for meat and offal; previously it was 28 days. The increased withdrawal period is due to further studies being completed and increased sensitivity in residue testing. The change takes place immediately, so even though the label of purchased product may state a 28-day withdrawal period, you need to adhere to the new 58-day withdrawal period.
