PENKOV, D., 2007. Duration of balance trials with caecectomized Muscovy drakes (C. moshata L.). Bulg. J. Agric. Sci., 13: 375-378

The decrease of excretion of caecectomized 42-44 wk. Muscovy drakes up to minimum relatively stable levels was evaluated by measuring excreted dry matter and amino acids in regular intervals. The dynamics of the quantity of excreta and amino acids was recorded up to the 12th hour after starvation, followed by relatively stable minimum values. The recommended period of cleaning of the digestive tract of caecectomized Muscovy drakes should be 12 to 18 hours.

Key words: Muscovy drakes, caecectomy, endogenic excretion, starvation, dry matter, amino acids
