GENERAL 11 Otago Daily Times Monday, October 19, 2020 @ Otago Daily Times North Otago Focus on Farming Advertisin­g Feature Effective flystrike prevention in spring Speaker series a highlight of Otago Field Days PREVENTION is the best cure! Coming back from Christmas holidays to find fly­blown lambs and ewes is very demoralisi­ng. Even a 50c piece size area of flystrike can stop a ewe cycling for a month. In lambs the loss of growth, suffering and deaths along with the time dealing with the mess are enough for many to vow to get things sorted before Christmas next year. Crutching, and a regular effective drenching program are essential. Planning your program is critical. What length of protection do I need? What product should I use? When should I apply it? There are new chemicals on the market to consider and we have to be more aware of chemical resistance and using these resources in an effective and sustainabl­e way. Mode of delivery and class of stock is one place to start a discussion on fly control. DR Peter Amer covered the subjects of plant and animal breeding and genetics and his work in a national and internatio­nal context. Jason Harvey­Wills and James Muwunganir­wa demonstrat­ed a process to enable farmers to be compliant with legislatio­n. Their valuable contributi­on showed how, via a series of small steps, compliance is not as insurmount­able as many perceive. Tony Pearse spoke on behalf of the deer industry and their significan­t progress in genetics and the marketing of the Cervana brand, from farm to plate. Murray Harris and Olivia Sanders talked about forestry, revegetati­on, and carbon credit opportunit­ies. Ken Algie demonstrat­ed how farmers can receive better than the offered prices, especially for crossbred wool, through marketing innovation­s and direct supply to a manufactur­er. Peter Barratt gave a graphic and powerful shorter period of protection but also shorter meat withholds. 2. JETTING TREATMENTS Jetting can work out cheaper and achieve full body coverage. As with all chemical protection, effectiven­ess depends on the amount and volume applied. Chemical does not work in dags. Checking to ensure animals are saturated to the skin is important. Many of the jetting race units will struggle to deliver the required amount of chemical to each animal. Note that IGR chemicals only work as prevention, and do not kill existing strike. A A A Extinosad at other times then Cyrazin­KO could be considered, which contains Ivermectin and has a claim for up to 14 weeks fly protection. Ivermectin does strip out of solution so is not considered for shower dips or where fluid is recycled. There are of course many other finer points to discuss with a veterinari­an around fly prevention program. The main thing is to make some time to discuss a program and get the right chemical on before the first wave of fly pressure hits. 1. SPRAY­ON TREATMENTS 3. EARLY STRIKE Spray–on products are generally used for lambs at tailing or weaning. CLiKR spray­on, at tailing has been a revolution for lamb fly control, especially fine wool lambs, giving 4­5 months protection. The new improved version Clik Extra has a shorter 21 day meat with­hold giving it more flexibilit­y for use in meat breeds. Cyromazine­based spray­ons such as VetrazinR or CyrazinR have been popular for crossbreds, giving a If early strike is already present then a combinatio­n product is advised. CyrexR or Cyrazin­KO are options both containing Cyromazine, an IGR for long term preventati­ve treatment, plus an instant kill chemical. Cyrex contains Spinosad which is the active ingredient of Extinosad, a widely used lice treatment with good kill of existing maggots. If you do repeatedly use presentati­on about the transforma­tion of Linnburn Station form a convention­al “short grass” breeding farm to a finishing property, based on diversity and high biomass systems. This topic prompted vigorous discussion. Otago Field Days is now five years old and this speaker series has establishe­d its identity and purpose. Thank you to the exhibitors for their continued support — please support them. Also thanks to the volunteers and the Palmerston & Waihemo A&P for the use of their grounds. Roll on 2021.
