Abstract

The aim of present study was to estimating nutritional value of fresh or dried sunflower disc florets (SFDF) using in vitro gas production technique. Three fistulated native bulls fed experimental rations twice daily for 15 days, and ruminal fluid was collected for using in in vitro fermentation. Gas production of in vitro fermentation was measured as the volume of gas in the calibrated syringes and was recorded before incubation 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours after incubation. Total gas values were corrected for blank incubation which contained only rumen fluid. The fresh SDFD has significantly more fermentation potential when compared with dried SDFD. All of gas production fractions (soluble, insoluble, and potential gas production value) are greater for fresh SFDF in comparison with dried SFDF. Also, all of energy indices include organic matter digestibility (OMD), metabolizable energy (ME), short chain fatty acids (SCFA), and net energy for lactation (NEL) are significantly greater for fresh SFDF. It can be concluded that fresh sunflower disc floret (as a sunflower seed by-product) can be used in ruminant nutrition. However, drying of this feedstuff can decrease its nutritional value.
