You may smell ketones on her breath, and many animals will have a wool-break. Generally, there are not huge numbers affected at once, but it will be progressive through the mob. Metacam used for lamb marking ; induce lambing drugs from local vet. Prevention: Run sheep at a slightly lighter weight CS 2.
Deft, quick handling at pre-lambing treatments. Get them in and out of the shed quickly and back on feed. Determinants include: Change from dry to lush pasture in late pregnancy Prolonged yarding, handling or transport Chronic grain feeding without calcium supplement. Chronic exposure to irrigated green grass or winter cereals.
Native pastures are rarely deficient in calcium. Clinical signs: Sheep go down suddenly, and appear relatively bright and alert in the early stages. They will become dull over time. If you hyper-supplement them in early pregnancy their capacity to absorb dietary calcium goes down. When the load for calcium increases late pregnancy, if the parathyroid is already wound down the ewe will struggle to cope. Put the limestone into a hopper and mix with grain up the auger.
Otherwise put the limestone on the top of a grain bin and let it shake down less effective. If you have triangular feeders that have a V in the middle, place calcium there, but too much lime in self feeders can block them up. If you are trailing grain, you may need to look at providing an additional calcium supplement — the cheapest is a limestone:salt mix, or use blocks. Clinical signs: Last month of pregnancy in fat multi-bearing ewes Vagina partially everts in the last month To be distinguished from prolapsed uterus post lambing and vaginal evisceration.
Treatment: Wash them down, squeeze them up with a towel to move the blood out of them, and push prolapse back in Hold in place with sutures or retaining devices You may decide to induce lambing — success rate is pretty good provided you can get the lambs out Note: a uterine prolapse occurs after lambing, is twice as big, and has lumpy bits on it Prevention: As we only have a poor handle on the determinants, these are recommendations only.
Body condition: aim to keep prime lamb ewes at CS 2. This will provide lots of benefits in other areas ease of lambing, casting, ewe mortality Follow the recommendations for Merinos tail length. The risk was higher on farms with moderate to steep terrain than on farms with flat terrain. The identified risk factors in the individually identified cohorts were: access to salt and feeding of swedes in the latter part of pregnancy, moderate to steep lambing paddocks, multiple lambs detected at scanning, and weight gain between start of mating and scanning.
Culling policies for female offspring of affected ewes did not influence incidence at the farm level; nor did feeding hay or grain in late pregnancy. Furthermore, there was no association between incidence and body condition scores measured prior to and after mating, at scanning, or at time of set stocking.
Clinical significance: Vaginal prolapse is an inevitable consequence of sheep reproduction and its incidence is expected to increase as reproductive rates increase. Wash the prolapse with plenty of clean, warm water containing a suitable antiseptic or disinfectant.
Ensure contamination such as muck and straw are removed. In either case seek veterinary advice. If intestines are visible through a tear, euthanasia is advisable. Always handle the prolapse carefully to avoid damage.
Try using either the flat of your hand or a fist. With many prolapses the urinary bladder has actually flipped up inside the prolapse, blocking the neck of the bladder. If you gently lift the prolapse up, towards the tail, this often allows the ewe to pass urine and the prolapse will reduce in size. Often a ewe will continue to strain during replacement, but avoid pushing harder against her; instead just use enough pressure to stop the prolapse coming back out when she strains, then when she stops continue to replace it.
Once you have successfully replaced the prolapse, there are three ways to keep it in the ewe.
