Extract

Nutrient deficiencies, such as sulfur (S), that reduce the activities of rumen microorganisms are liable to reduce food intake (McDonald et al., 1995). Hegarty et al (1994) found that a depression of appetite and digestibility in sheep deprived of sulfur. The amount of sulfur needed to optimize the rumen environment is dependent on several factors such as the level of dietary sulfur and the availability of the effective ruminal degradable nitrogen, ERDN (Underwood and Suttle, 1999). Therefore, this trial was conducted to assess the influence of different ERDN:S ratios on the dry matter intake (DMI) and nutrients digestibility in the male goat of Raini breed, an Iranian native cashmere goat.
