KEEPING EVERY LAMB ALIVE: PREVENTING EWE REJECTION THROUGH STRATEGIC FARMING
Strategic farmers know that the first hours after birth are critical. While most ewes readily bond with their lambs, some unexpectedly reject them, either one or both in the case of twins. This rejection can lead to starvation, illness, and even death if it is not managed promptly. Understanding why rejection happens, and how to prevent it, is essential for any farmer committed to profitable, sustainable, strategic farming.
Why Ewes Reject Their Lambs
Rejection can be traced to several causes. Some originate from the ewe herself, such as when she carries a heavy worm burden that interferes with her sense of smell, especially when nasal bot is present. Mastitis is another common issue; the pain and inflammation associated with it discourage suckling, and the lack of milk leaves lambs without nourishment. Ewes that are malnourished or weakened from starvation are often unable to show the care required, and stress, whether from predators, noise, or overcrowding - further undermines maternal behaviour. There are also cases where a ewe simply lacks maternal instinct altogether.
The lamb itself may also play a role in rejection. A weak or sickly lamb is sometimes abandoned instinctively, as the ewe conserves her energy for stronger lamb/s. When twins are born, it is not uncommon for one lamb to be favoured while the other is neglected.
Environmental and human factors add further complications. In group lambing situations, confusion can arise when many ewes give birth at the same time, causing the scent signals that guide recognition to be mixed. Human interference can also play a part: handling lambs too soon after birth may alter their scent, which may cause the ewe to fail to recognise them. Finally, unsafe lambing areas that expose ewes to stress and predators can result in rejection.
Strategic Interventions from Mating to Weaning
At Talitha Pharma, we emphasise strategic farming - planning and preparation that begins long before lambing, ensuring both ewe and lamb are given the best chance of survival and growth. Proper nutrition is critical, with supplementary feeding and the inclusion of essential salts, vitamins, and nutrients playing a major role. TaliMune PLUS supports immunity in the ewe, helps reduce the risk of mastitis, and improves milk production. Alongside this, TALIROX 34 provides robust parasite control so that the ewe is not competing with worms for the nutrients she needs for her health and her lamb’s vitality.
Vaccination and deworming, carried out 4 to 6 weeks before lambing, have a dual benefit. They not only strengthen the ewe but also improve the quality of the antibodies in her colostrum. When lambs ingest this enriched first milk, they receive stronger protection against disease, setting them up for survival during their most vulnerable stage.
Safe management practices at lambing are equally important. Housing ewes in protected lambing pens close to home ensures that they are shielded from predators and other disturbances. Providing shelter during winter reduces stress from the cold, which is one of the leading killers of lambs. Close observation during lambing allows for timely intervention when difficulties arise, ensuring that the ewe-lamb bond is not disrupted.
Caring for lambs also requires proactive measures. Bonding between ewe and lamb should be carefully facilitated in the hours immediately after birth. If rejection does occur, farmers may need to intervene by restraining the ewe while the lamb suckles, fostering the lamb onto another ewe that has lost a lamb, or in some cases resorting to hand-rearing. Hand-rearing is another area where SureWean RTU plays a crucial role, by helping weak lambs cope with stress, building their immunity, and supporting their growth through this vulnerable phase.
The Bigger Picture
Every lamb lost to rejection or starvation is a direct blow to farmer's profitability. Yet these losses are preventable through a combination of sound flock management and the use of scientifically proven health solutions. By integrating TaliMune PLUS, TALIROX 34, strategic vaccination, and SureWean RTU into their management systems, farmers can reduce lamb losses significantly, build stronger flocks, and secure sustainable returns.
