| Popis: | Objective The study was conducted to determine the apparent total tract digestibility, the rate of digesta passage, growth performance and physicochemical properties of the digesta of Windsnyer pigs fed on increasing levels of potato hash silage. Methods Diets were formulated to contain 0, 80, 160, 240, 320 and 400 g potato hash silage /kg of diet. Pigs were randomly assigned to six diets according to a completely randomized design. Six pigs were allocated to each dietary treatment. All diets were blended with chromic oxide (Cr2O3) to calculate apparent total tract digestibility and rate of passage. Pigs were fed diets containing different levels of potato hash silage for 5 d, following 7 d of adaptation. Thereafter, pigs were subjected to a 35-day growth performance experiment. Thirty-six pigs were slaughtered and eviscerated to determine digesta characteristics and gut compartment weights. Results There was a positive correlation (P < 0.05) between MRT and each of DMD, OMD and CPD. There was a quadratic increase (P |
