Full TextAbstract
The effect of inclusion of soya hulls (SH) as grains or forages sources in rations of dairy cows have been studied in many experiments. However, when SH are used to substitute for forage sources they induced milk fat depression, lower rumination time and ruminal pH (Weidner and Grant. 1994a, b). There is no data on effectiveness of diet particle size when SH used as a forages source. The objective of this study was to investigate the effect of physical effectiveness factor (pef) of diet on utilisation of SH in dairy rations.
