THE YIELD AND CHEMICAL COMPOSITION OF MILK OF COWS FED THE RATION WITH PROTEIN-FIBROUS-EXTRUDERATE
2009
Andrzej TARKOWSKI
The present research evaluated the effect of protein-fi brous extruderate on yield and chemical composition of milk obtained cows. Protein-fi brous extruderate produced from dry sida (Sida hermaphrodita (L) Rusby) and horse bean meal was compared to a standard concentrate mixture “B” comprising maize silage and meadow hay. Daily yield milk appeared to be comparable between two treatment groups, one fed a protein-fi brous extruderate supplemented diet and other – a standard concentrate. A higher fat and protein content was determined in milk from cows with a dietary protein-fi brous extruderate additive.
