Greyhound racing will be banned in New South Wales from July 1 next year after Premier Mike Baird said the "widespread and systemic mistreatment of animals" cannot be tolerated.

Mr Joyce has said that he does not agree with the state governments ban on greyhound racing and that there is a “better alternative”.

Tamworth’s Mr Khan has backed Local MP Adam Marshall’s call for Mr Joyce to “Butt out” of commentary regarding the decision.

“My Federal leader, Barnaby Joyce, like a few of my state colleagues, has opposed the decision of the state government to ban greyhound racing in NSW, I get it, I accept that people will oppose the decision, although I don't agree,” Mr Khan said.

“Having participated in the 2013/14 Legislative Council Inquiry into Greyhound Racing, and having taken the time to read the McHugh Report, I am comfortable the decision made by the NSW Cabinet is the only decision that can be made. 

Mr Khan said that recent commentary has favoured emotion over facts.

“Sadly too many people who have contributed to this debate, including our Deputy Prime Minister, have failed to read the available evidence, too many have proceeded on either gut instinct or politics, or simply emotion,” he said.

“The evidence to the Committee was that Greyhounds is in irreversible decline and unfortunately there is no pot of money available to fix Greyhounds' many problems.”

Greyhounds Transition Taskforce Coordinator General Dr John Keniry said the NSW Government has committed to a raft of measures, which includes financial assistance.

"Later this month I will be visiting several regional centres across NSW to hear first-hand the issues people are facing due to the closure on July 1, 2017 to ensure as many views as possible form part of my report to government."
