Effects of dietary n-3 polyunsaturated fatty acids and ... - FINS

1 st WorkshopXIII International Feed Technology SymposiumMaterial and MethodsThe study was carried out in two different Stations for Artificial Insemination (SAI 1 andSAI 2) during the 3 year period. 108 samples of blood from V. jugularis were analyzedfor content of total protein, blood glucose, Ca, P and Mg. Levels of Zn both in the bloodand the sperm were estimated at 32 and 24 samples respectively.Feeding: The experimental protocol shows that during the years there were periods withor without additive (table 1); to daily rations, composed by meadow hay (65%) andcompound feed (35 %). During the experimental periods sires received in addition toconcentrate part of daily ration per 0,5 % BIOPRO.Main resultsTable 4.
