Evaluation of the nutritional value of goat forages in Shandong Province

doi:10.11686/cyxb2014280

Abstract

Abstract: This experiment was conducted to evaluate the nutritional value of common forages fed to goats sampled from 17 cities in Shandong Province. A total of 109 samples from 10 species were used to analyze common forage value and gross energy (GE). Forage attributes measured included in vitro dry matter digestibility (IVDMD), digestible energy (DE), metabolizable energy (ME) and crude protein (CP). An acceptability index of all forages was calculated using voluntary dry matter intake. The results revealed that the nutritional value of goat forage cannot be accurately evaluated by conventional nutrient analysis. Digestible energy was highest in alfalfa hay followed by Secale cereale hay, sweet potato vine, Chinese wild rye, peanut stem, corn stalk silage, dried corn stalk, rice straw, soybean straw and wheat straw. IVDMD and DE were significantly negatively correlated with NDF and ADF, while IVDMD was positively correlated with CP.
