Ensiled slaughter offal as a protein source for growing pig
The present study was conducted in order to evaluate the use of slaughter offal preserved by lactic acid fermentation in pig diets. Offal was first ground, autoclaved, and mixed with 70 kg sugar beet molasses per 1000 kg. After that it was inoculated with 2x105 lactic acidbacteria/g and incubated at...

| Summary: | The present study was conducted in order to evaluate the use of slaughter offal preserved by lactic acid fermentation in pig diets. Offal was first ground, autoclaved, and mixed with 70 kg sugar beet molasses per 1000 kg. After that it was inoculated with 2x105 lactic acidbacteria/g and incubated at 35°C for three days. The final pH ofthe fermented product was 3.80. The ensiled slaughter offal (ESO) contained 239 g dry matter (DM)/kg. and 319 g crude protein (CP) and 403 g crude fat (CF)/kg DM. CP contained 47 g lysine, 33 g threonine, 16 g methionine, and 8 g cystine/kg. A digestibility and nitrogen (N) balance assay was conducted with eight barrows using a 2x4 factorial arrangement in a 8x4 cyclic change-over design. The factors were protein source and protein level. Barley-based diets were supplemented with increasing levels (0, 20,40, and 60 g CP/kg) of ESO or soyabean meal (SBM). Increasing the protein supply led to a linear increase in the digestibility of CP (p |
