A leading Danish veterinarian has confirmed that healthy sows have the ability to produce enough colostrum for 40 piglets.

The fact that they have difficulty feeding half this number successfully, reflects their poor health status.

Soren Spandet Thielsen, the owner of the specialist pig veterinary practice, OE-VET A/S, also stressed the need for Irish pig farmers to put an absolute focus on maintaining the health status of their sows.

He said: “Large numbers of Irish sows are suffering from undiagnosed bladder and urinary tract infections. These are leading to a number of conditions, including a mother’s inability to stand up effectively after farrowing.  

“The same principle holds when it comes to identifying chronic stomach ulcers in finished pigs. I estimate that approximately 45% of finished pigs in Ireland are affected in this way," Thielson added.

“Only when a farmer knows that problems of this nature exist can they then go about fixing them.”

The Danish veterinarian made these comments while speaking at a series of farmer meetings, hosted throughout Ireland by Glenmarshal Sires this week.

Where weaning is concerned, Thielsen recommended that piglets should be kept on the mother for 31 days and that they should weigh at least 11kg.

He explained: “Weaning at 28 days is too early. This is because the young pig has yet to develop its own immune system by that stage.

Farmers attending the meetings were told that they should practice an all-in/all-out policy, where finishing pigs are concerned.

“This approach to management acts to reduce disease spread within a herd," Thielson said.

“All the drinking points within a pig unit must be checked regularly.”

Commenting on the pros and cons of tail docking, Thielsen said that the practice can be done away with if the floor space available per pig is increased by 20%.

“Poor ventilation within pens can also encourage tail biting. Pigs suffering from any form of bacterial infection should not have their tails docked," he concluded.
