Translation help: tüchtig In Farm der Tiere, the following sentence appears (truncated in this example):

&gt;**Er zählte zwölf Jahre und hatte in letzter Zeit tüchtig angespeckt, war aber noch immer ein majestätisch anzuschauendes Schwein...** 

Orwell's original was:

&gt;**He was twelve years old and had lately grown rather stout, but he was still a majestic−looking pig...** 

The word tüchtig appears to be associated with the definitions:  hardworking, diligent, capable.

Is the German version of this sentence using *tüchtig* to imply that "Er" (Old Major, the senior pig who inspires the revolution) has been dutiful in getting fat? Or is it simply being used as an intensifier, like Orwell's "rather".
