Abstract :
The study evaluated the digestibility of potato hash silage (PHS) using 24 crossbred sows (± 30 kg live weight) that were housed individually. Four diets containing either no PHS (control) or 600 g/kg PHS [untreated PHS, Lactobacillus buchneri (LB) PHS and Bonsilage forte (BF) PHS] were formulated and fed ad libitum to the pigs. Experimental period lasted for eleven days (seven days adaptation and four days faecal collection). Intake of organic matter (OM), crude protein (CP), ether extract (EE), fibre and gross energy (GE) was reduced (P < 0.05) in diets containing PHS compared to the control. Digestibility of dry matter (DM), EE, and GE was not affected by treatment. It was concluded that dietary addition of 600 g/kg PHS did not improve nutrient digestibility in pigs. Therefore work that will evaluate the optimal effects of higher dietary ( > 600 g/kg) inclusion level of PHS is warranted.
