Quality assurance procedure |
Action |
Breeding: use only high performance LAMBPLAN tested meat breed rams that are faster growing, leaner and heavier muscledthan average. Source ewes of high genetic merit. |
Record LAMBPLAN figures and monitor yearly purchases. |
Marking and vaccination: mark lambs between 3 and 6 weeksof age. Minimise carcase and pelt damage by vaccinating behind the head or ear. |
Vaccinate only on the head or neck. Record date, volume and vaccine used. |
Pastures: graze lambs on high-quality pastures to achievetarget growth rates from birth to sale. Manage stock to achieve constant growth rates in lambs |
Weigh a sample of lambs at marking, weaning and prior to sale. |
Management: draft lambs into three weight ranges so the growth rates of different mobs can be monitored. Assess mobs close to target sale weight and fat score. |
Record weaning weights and segregation dates. |
Mustering: avoid excessive stress on lambs and move themcarefully in hot weather. Muzzle all dogs and use low stress stock handling methods (see procedure 11.5 in Healthy and Contented Sheep). |
Watch the weather. Use well trained dogs and adopt low stress stock handing techniques. |
|
Assessment for sale: weigh all lambs 2-3 hours off feed and draft those meeting target specifications. Use an estimated dressing percentage to calculate carcase weight.
Fat score about 20% of each weight category at the GR site. If the processor has a strict grid that rewards targeted GR ranges then fat score all lambs.
Take care when forcing lambs, to avoid skin and pelt damage.Complete National Vendor Declarations for each consignment. |
Record all liveweights, fat scores of sale lots and the estimated carcase weights.
Make comparisons to feedback sheets.
Do not use spray marks on the main body area. |
Health treatments: observe the correct with holding periods for any drenches, dips or antibiotics used. |
Keep a record of treatment dates and application rates. Supply records on request. |
Crutching and shearing: ensure sale lambs are free of faeces and stain. Bung-hole crutch only to maximise skin value. Crutch at least four daysbefore sale to avoid stress. Do not send lambs to market with unhealed or infected wounds. |
Record dates of crutching and shearing. |
Loading transport: move lambs quietly to avoid stress. Use muzzled dogs. Do not lift lambs by the wool. Keep lambs off feed and water for at least 12 hours prior to trucking. Observe recommended trucking densities. |
Watch the weather. Use accredited livestock carriers. Agree to a loading time. |
Marketing: use market coordinators or agents to trade lambs on a Hot Standard Carcase Weight basis, preferably within a marketing alliance or agreement. Seek feedback on each consignment. |
Apply a professional approach to marketing and use feedback in a continuous improvement program. |
