Given that in the rectangular coordinate system $(xOy)$, the origin is the pole and the positive semi-axis of $x$ is the polar axis to establish a polar coordinate system, the polar coordinate equation of the conic section $(C)$ is $p^{2}= \frac {12}{3+\sin ^{2}\theta }$, the fixed point $A(0,- \sqrt {3})$, $F\_{1}$, $F\_{2}$ are the left and right foci of the conic section $(C)$, and the line $l$ passes through point $F\_{1}$ and is parallel to the line $AF\_{2}$.
(I) Find the rectangular coordinate equation of conic section $(C)$ and the parametric equation of line $l$;
(II) If line $l$ intersects conic section $(C)$ at points $M$ and $N$, find $|F\_{1}M|⋅|F\_{1}N|$.
