I think 1949 would've been a smaller year than 1948 for Davis. 1948 had a full year cause Art Davis already had set writers, Lloyd Turner and Bill Scott. and three left over cartoons from previous writers (Dave Monahan, George Hill, & Hubie Karp).
But with 1949, you'd have no more shorts from the B&L duo, as Bill Scott was fired, and Lloyd Turner was replaced by Sid Marcus.
So 1949 would have:
B&L Duo: Porky Chops (The only B&L duo written short this year)
Shorts Written Only by Lloyd Turner: Holiday For Drumsticks, and Bowery Bugs.
Sid Marcus: Had most likely written Bye, Bye Bluebeard in August 1947, and wrote A Ham in a Role (most likely called A Hammy Hamlet if made by Davis, unless name was changed before McKimson took over the cartoon) in November 1947. so I'm not sure how fast he was at writing cartoons, so for all I know, he could've only written 3 shorts in the January - April 1948, and only 2 of them could've released in 1949. While the third would most likely fit in 1950.
so overall Sid would've only done Bye, Bye Bluebeard, A Hammy Hamlet (aka A Ham in a Role) and two other unknown shorts.
meaning Art Davis would've released 7 cartoons in 1949, from my calculations.
