If you use ga.js ("traditional" asynchronous code) you have to use _gaq.push. If you use analytics.js you need to use ga send. The methods are not interchangeable, they belong to two different versions of the Google Analytics tracking code.

By now (2017) there is a new code version (gtag.js), so if you are using that you use neither ga nor _gaq.push but instead follow the migration guidelines to bring your code up to the latest version (or you quite sensibly start to use Google Tag Manager).
