Unlike some of the other southern states, Louisiana did not publish a list of reasons. But the leaders of Louisiana did leave us plenty of information. Take, for example, a speech given by George Williamson, a representative from Louisiana to the Texas succession convention. It is pretty clear, but for the reading challenged I direct you to the relevant language in the third paragraph.

Specifically
"The people of Louisiana were unwilling to endanger their liberties and property by submission to the despotism of a single tyrant, or the canting tyranny of pharisaical majorities. Insulted by the denial of her constitutional equality by the non-slaveholding States, outraged by their contemptuous rejection of proffered compromises, and convinced that she was illustrating the capacity of her people for self-government by withdrawing from a union that had failed, without fault of hers, to accomplish its purposes, she declared herself a free and independent State on the 26th day of January last. History affords no example of a people who changed their government for more just or substantial reasons. Louisiana looks to the formation of a Southern confederacy to preserve the blessings of African slavery, and of the free institutions of the founders of the Federal Union, bequeathed to their posterity. As her neighbor and sister State, she desires the hearty co-operation of Texas in the formation of a Southern Confederacy. She congratulates herself on the recent disposition evinced by your body to meet this wish, by the election of delegates to the Montgomery convention. Louisiana and Texas have the same language, laws and institutions. Between the citizens of each exists the most cordial social and commercial intercourse. The Red river and the Sabine form common highways for the transportation of their produce to the markets of the world. Texas affords to the commerce of Louisiana a large portion of her products, and in exchange the banks of New Orleans furnish Texas with her only paper circulating medium. Louisiana supplies to Texas a market for her surplus wheat, grain and stock; both States have large areas of fertile, uncultivated lands, peculiarly adapted to slave labor; and they are both so deeply interested in African slavery that it may be said to be absolutely necessary to their existence, and is the keystone to the arch of their prosperity."
There is more, but I trust you get the idea.
