[Nutritional value of wine yeast for sheep and swine]

A digestibility trials was carried out with male sheep and one with fattening pigs to investigate the digestibility of wine yeast. 4 two-year-old male sheep and 5 castrated male pigs (live weight approximately 80 kgs) were used as experimental animals. The following digestibility data (%) were established on the sheep: organic matter: 78.9; energy: 79.1; crude protein: 61.1; crude fat: 88.8; crude fibre: 88.8; NFE 86.1. The corresponding data for the pigs were 55.4; 46.3; 22.7; 12.1; 92.7; 69.8. Thus, the resulting energy concentration was approximately 630 EFr units or 405 EFs units and the content of digestible crude protein in the dry matter was about 16% for ruminants and 6% in the pigs.
