in 1989 when he became the managing director of Tenon Developments. In a joint venture with Morrinsville Thames Cooperative Dairy Company, they developed a method of producing cholesterol-free butter and low-fat meats using extraction technology.
He remained the managing director of Tenon Developments Ltd until his death.
While the research project was dropped by the New Zealand Dairy Group, McLachlan's interest in the subject of cholesterol and heart disease remained. He spent five years investigating a potential connection between A1 beta casein protein consumption and heart disease.
In 2000, he formed
A2 Corporation, backed by
Howard Paterson to license technology for testing, production and use of milk containing only the
A2 beta casein protein and no A1 protein (primarily which the
BCM-7 peptide is a variant of) in cows' DNA.

Research
McLachlan began his research into milk consumption and heart disease prevalence in different countries in 1994 and continued this work for five years. His research concluded a strong link between the consumption of the A1 beta casein protein and

are instead sensitive to the A1 protein. Using a genetic test, McLachlan was able to identify cows that produce only the A2 protein. McLachlan's conclusions were not accepted among all scientists; many pointed out that the research was ‘correlative, rather than proven cause and effect’.
McLachlan authored 29 scientific papers and confidential reports and was awarded 11 patents. In 1995, McLachlan was made an honorary senior research fellow of the School of Biological Sciences at the

Death
McLachlan died of cancer on 9 August 2003.
At the time, acting chief executive of A2 Corporation, Andrew Clarke, said, "This has been a double tragedy for A2", referring to the deaths of both McLachlan and Howard Paterson within a short period of time.
