Effects of Enriched Charcoal as Permanent 0.2% Feed-Additive in Standard and Low-Protein Diets of Male Fattening Turkeys: An On-Farm Study

Animals, 2019
Wet litter is the most important cause of footpad dermatitis in poultry, this in turn being a highly relevant animal-related welfare indicator. This field study was subdivided into two experiments. In Experiment 1, the standard diet was supplemented by 0.

Compensatory renal growth after unilateral ureteral obstruction

Kidney International, 1973
Compensatory renal growth after unilateral ureteral obstruction. The accumulation of bulk renal protein, RNA and DNA was studied in mice during a 35-day period of accelerated renal growth in the kidney contralateral to that obstructed by acute ureteral ligation. Control mice were sham-operated and non-operated.
