[The content of ascorbic acids in different tissues of cattle, normally developed piglets, splay-legged piglets, adult swine and dogs].

The following ascorbic acid levels were recorded from different organs of cattle, with all values quoted being related to mg/100 g fresh matter: 150 +/- 20 in pituitary gland, 170 +/- 40 in left adrenal gland, 45.5 +/- 12.5 in spleen, 38.1 +/- 7.3 in liver, 30.0 +/- 8.5 in cerebrum, 23.2 +/- 7.2 in cerebellum, 16.4 +/- 6.1 in kidney, 11.0 +/- 2.9 in heart, and 9.1 +/- 2.1 in M. longissimus dorsi. The ascorbic acid level in blood plasma of normally developed piglets was 6.5 +/- 2.7 mg/dl and was thus higher with significance (p less than 0.01) than that recorded from splayleg piglets which was 2.3 +/- 0.96 mg/dl. The levels in the M. semimembranosus and M. semitendinosus in piglets of moderate birth weight were higher, as well (p less than 0.05). The liver level in pigs for slaughter was 30.8 +/- 9.0 mg/100 g lower than that in piglets. Piglets exhibited genetically founded differences in their capability of biosynthesis of ascorbic acid. The highest ascorbic acid level in dog was recorded from the pituitary and adrenal glands, values being 135.5 +/- 7.5 mg/100 g fresh matter or 90.3 +/- 37.8 mg/100 g. Their liver level was 27.9 +/- 11.9 mg/100 g.
