Bovine Tuberculosis

Debate between Lord Soulsby of Swaffham Prior and Lord De Mauley

Tuesday 26th November 2013 Lords Chamber

[Lord De Mauley]

The noble Countess makes an extremely good point, and I cannot disagree with what she says.

[Lord Soulsby of Swaffham Prior (Con)]

My Lords, artificial insemination has been a practice in this country in dairy cattle for more than 30 years, and I wonder where this suggestion has come from. There is very little evidence—no evidence whatever to my mind—that AI can result in the transmission of TB to cattle. I hope that the Minister will scotch that idea, because we have an amazing health record in this country for AI and tuberculosis control.

[Lord De Mauley]

I am most grateful to my noble friend because he enables me to say, perhaps more categorically than I said to start with, that research indicates that there is no link between TB susceptibility and milk production traits.

Badgers

Debate between Lord Soulsby of Swaffham Prior and Lord De Mauley

Tuesday 11th December 2012 Lords Chamber

[Lord Soulsby of Swaffham Prior]

I thank the noble Lord. My Lords, in view of the vast compensation paid for the slaughter of cattle that react to the tuberculin test, and in view of Britain’s vast experience of vaccination of wildlife—not only of badgers but all over the world—what attention is being paid to the vaccination of badgers in this situation by using techniques that are commonly used elsewhere in the world in very difficult circumstances?

[Lord De Mauley]

My Lords, I mentioned earlier the injectable badger vaccine, with which, as I explained, there are complications. The other alternative is the oral vaccine. An oral badger vaccine is in development but is still several years away. It is therefore not possible to say with any certainty if and when such a vaccine might be available for use in the field.

Schmallenberg Virus

Debate between Lord Soulsby of Swaffham Prior and Lord De Mauley

Thursday 1st November 2012 Lords Chamber

[Lord Soulsby of Swaffham Prior]

My Lords, it is good news to hear that vaccines are being developed against the Schmallenberg virus although it takes time to authenticate the vaccine, get it licensed and the rest. A short-term approach could be to delay the breeding of cattle and sheep to a time when the insect vector—the biting midge—is less active because it is only through the biting midge transmitting the virus that this infection is transmitted from animal to animal. Has the Minister information about any work that is going on as regards advising farmers to delay animal breeding until there is less midge activity?

[Lord De Mauley]

Yes, my Lords, I have looked into this suggestion. It is possible that delayed tupping may help. We recommend that farmers discuss this with their vets as there are many interdependencies for each farm relating to the timing of tupping and the overall benefits need to be considered. If a flock is not infected yet, delaying tupping may work only if disease infects the ewes before tupping takes place.

Bovine Tuberculosis

Debate between Lord Soulsby of Swaffham Prior and Lord De Mauley

Tuesday 23rd October 2012 Lords Chamber

[Lord Soulsby of Swaffham Prior]

My Lords, in view of the great success in controlling rabies in foxes in western Europe with an oral vaccine, has much thought been given to the production of an oral vaccine for TB in badgers? I realise, of course, that the organisms are entirely different; one is a virus and one is a bacterium. However, surely the same process of trying to select an organism that is protected before it gets into the gut and immunises the badger is worthy of investigation. Can the Minister give some indication of some of the work that is going on, if any, on the production of an oral vaccine similar to the one developed for fox rabies?

[Lord De Mauley]

I am grateful to my noble friend because this is an important subject into which considerable work is going on. The evidence that he has referred to will of course be taken into account. Progress on the development of an effective oral badger vaccine relies, of course, on scientific breakthroughs in this field, and it is uncertain in outcome and timing. Compared to an injectable vaccine, an oral vaccine is technically more difficult to formulate, as my noble friend alluded to, and it requires bait, which encourages the uptake of the vaccine by badgers and minimises the potential of other species to eat it. Developing an oral vaccine against TB in badgers is proving more difficult than originally hoped, which means that I cannot say with certainty when one might be available for use in the field.
