magento get stock information of product

$stock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product);

You can check stock data in this way:-

echo "<pre>"; print_r($stock->getData()); echo "</pre>";

Or, you can print individually like this:-

echo $stock->getQty();
echo $stock->getMinQty();
echo $stock->getMinSaleQty();
