According to a team of experts from UP at Los Baños, adding ascorbic acid or Vitamin C to the diet of pigs — 800 gms. for every kilo of feeds, will make them grow faster compared to those treated with normal diets.
It was further noted that Vitamin-C treated pigs when slaughtered had a higher dressing percentage, leaner backfat and more lean cut yields.
