What type of propaganda is the following statement from chapter nine?

"It had been found necessary to make a readjustment of rations... but in comparison with the days of Jone, the improvement was enormous. Reading out the figures in a shrill, rapid voice, [Squealer] proved to them in detail that they had more oats, more hay, more turnips than they had had in Jone's days, that they worked shorter hours, that their drinking water was a better quality, that they lived longer and that they had more straw in their stalls and suffered less from fleas."
