help regionprops
This allows you to return the orientation, major axis length, and minor axis length of binary data with regions that approximate ellipses.
See here for more: http://blogs.mathworks.com/steve/2010/07/30/visualizing-regionprops-ellipse-measurements/
The page also contains code for plotting your ellipse fits.

Regionprops performs its operations for each connected region of true values, so it treats that cluster of three pigs as a single entity.
The way you do this likely depends on the range of scenarios that you expect from your images. I would suggest looking through the functions in the Image Processing Toolbox, particularly those that relate to Segmentation to see which ones might be useful.
