Beef and lamb NZ recently ran a seminar entitled ‘Scanning to Lambing’ in Seddon where extremely dry summers are the norm and the maintenance of the body score of ewes is uppermost in local farmer’s minds. Trish Lipeat from Vet Marlborough emphasised the importance of nutrition during the last 4 to 6 weeks prior to lambing. During this period the lambs are growing fast and take up an increasing amount of room in the gut of the ewe, leaving less space for the processing of bulky food. The feeding of high energy supplements is important at this stage especially to ewes carrying twins. Ewes should ideally have a BCS of 3 at this stage and if she is not being provided with enough high energy nutrition the lambs will take the energy from the ewe’s back. This will result in the lactation not reaching its potential and a penalty of kgs/lamb at weaning. Several farmers present were feeding barley or nuts and some were worried about mismothering if the feeding regime was continued after lambing. Tom Fraser suggested that a change of vehicle from the one that was feeding out supplements before lambing would be enough to stop the ewes clustering around the farmer’s transport. He also said that training ewe hogget’s to come to barley or nuts in summer dry country whatever the type of season would make them remember for the rest of their lives. Another member of the audience maintained the wisdom of always having some sheds full of hay made in abundant seasons as an insurance policy against the years of drought. Questions were asked about the timing of the administration of clostridial vaccines. Trish said that ideally it should be given 4 weeks before the start of lambing but conceded that the spread of the lambing period would result in different levels of protection for early and later lambers. She also advised the use of LSD prelamb at the same time as the administration of clostridials. Those using fodder beet as a supplement should give animals a fibre supplement whilst on the crop. No sudden changes to the diet should be made, allow time for the rumen bacteria to adjust to alterations in the feed regime. Faecal egg counts have been low but Trish warned that ewes will be using energy to fight worms and it would be good practice to give capsules to leaner ewes and multiple bearing ewes diverting energy to growing lambs. The timing of shearing was discussed and the amount of energy used by a shorn ewe to maintain body temperature. The options for a tough season such as this were not to shear or to shear early. Pasture growth rates have slowed so there are fewer incidences of nitrate poisoning, not so many bearings or sleeping sickness. So, there are some advantages to tough times.
