The Government says the badger cull in Gloucestershire killed just over half the original target but may extend policy next year
An online petition against the cull of badgers which was started by Queen guitarist Brian May has secured more than 250,000 signatures.
Two trials of badger culling can legally get underway on Saturday 1 June.
The three week extension of the badger cull in Somerset has failed to reach its target.
The Government has announced 90 badgers were killed in the period up to Friday, taking the total number killed in the cull area to 940.
That represents a 65% reduction in the badger population - less than the 70% target.
– Owen Paterson, Secretary of State for Environment, Food and Rural Affairs
Today I am announcing to the House that the three week extension period in
the Somerset control area concluded as planned on Friday 1st November.
During this period, a further 90 badgers have been removed, giving an overall total of 940 for the first year of the four year cull.
This represents a reduction of 65% in the estimated badger population before culling began.
This will deliver clear disease benefits as part of a four year cull in the area.
A similar cull in Gloucestershire has been extended until December 18th.
A group of around 20 Conservative MPs opposed to the badger culls are calling on the Environment Secretary to publish the independent evidence on the results.
A former scientific advisor to the Government has called a decision to extend the pilot badger cull in Gloucestershire by another eight weeks 'a travesty'.
Badger numbers in the area have decreased by less than a third since the cull began - the target was 70 per cent.
Dr Chris Cheeseman, from Stroud, says the decision will not help prevent TB in cattle, and that the government's decision is NOT being led by science.

Natural England has confirmed it has granted a licence to extend the pilot badger cull in Gloucestershire for another eight weeks.
The licence was granted following a confirmation that only 30% of the badger population had been culled during the initial six week pilot.
An extra three weeks has already been granted in Somerset, where 60% of the badger population was culled.
Queen Star and anti-badger cull campaigner Brian May has called for the resignation of Environment Secretary Owen Paterson over the pilot cull.
The guitarist said Mr Paterson had failed to meet the test of "honesty and transparency" expected by the public.
Statistics from the Department of Environment, Food and Rural Affairs (Defra) revealed that the six-week cull, which aimed to kill 70% of the badgers in Gloucestershire and Somerset failed to meet targets.
As a result, cull operators applied to Natural England to extend the shooting period.
The Badger Trust has issued a "pre-action protocol letter" over the proposed eight-week extension of the badger cull in Gloucestershire.
An extra three weeks was granted in Somerset, where 60% of the badger population was culled.
A "pre-action protocol letter" to Natural England and the Treasury Solicitor for the Secretary of State Secretary of State for the Department for Environment, Food and Rural Affairs has been actioned by the Trust.
It is the first stage in seeking a judicial review in the High Court, the letter states:
We consider that the decision to extend the cull in Somerset was unlawful, particularly in the light of those documents.
But given that we have only just seen them and given the relatively shorter extension there, we have advised our clients that it would not now be practicable (given the court process) to seek injunctive relief to prevent it.
But that is not the case in relation to the contemplated decision in relation to Gloucestershire not least because of the much longer extension (eight weeks) being sought (and not yet granted) and the fact that our clients have now seen the nature of the arguments being relied on to justify further culling.
The Badger Trust is mounting a legal challenge to halt an extension of the controversial badger cull pilot, it has emerged.
The opponents to the cull in Gloucestershire have formally warned the authorities to abandon the shooting or face a High Court challenge.
The challenge would be on the grounds that a plan to more than double the killing period is illegal, the Trust said.
Around 30% of an estimated 2,350 badgers were killed during the six-week pilot, rather than the planned 70%.
And in west Somerset 850 badgers had been culled during the pilot - 60% of the local population.
Figures out today show that as in Somerset, the controversial badger cull in Gloucestershire has failed to meet its target and may have to be extended.
Environment Secretary Owen Paterson MP claims the cull has been 'a success' in an interview with ITV News West Country's Ian Axton:
Environment Secretary Owen Paterson said the chief veterinary officer has advised that the period of culling badgers should be extended in Gloucestershire.
In a written statement to Parliament, Mr Paterson said the cull has killed 708 of an estimated 2,350 badgers in the county - less than 30% of the total rather than the 70% that had been planned.
Mr Paterson said an application is being considered by Natural England.
He told the House of Commons that early indications showed the culls in both Gloucestershire and neighbouring Somerset were carried out in a "safe and humane" way, but demonstrated that "the cull period may need to be longer than six weeks in future".
The number of badgers shot in Gloucestershire has fallen short of its target, the Government has announced.
Defra said 708 badgers have been culled, which is just 30% of the badger population.
