http://wordpressapi.com/2010/08/11/set-wordpress-post-excerpt-length-limited-characters/

First open your functions.php file and put following code in that file.

function get_excerpt($count){
  $permalink = get_permalink($post->ID);
  $excerpt = get_the_content();
  $excerpt = strip_tags($excerpt);
  $excerpt = substr($excerpt, 0, $count);
  $excerpt = substr($excerpt, 0, strripos($excerpt, " "));
  $excerpt = $excerpt.'... <a href="'.$permalink.'">more</a>';
  return $excerpt;
}

Use this function if you’re planning on using it more than once with a different amount of characters.

Call the function plus the amount of characters -

<?php echo get_excerpt(125); ?>

After that put following code in header.php file.

<?php if (function_exists('wordpress_breadcrumbs')) wordpress_breadcrumbs(); ?>

After putting above code we can see the breadcrumbs as following;
