Abstract

The aim of this study was to compare the differences in dry matter intake, nutrient apparent digestibility, rumen environment and excretion of total purine derivatives of two diets with different concentrate to corn rubbing stalk ratios between alpacas and sheep. Four 1-year-old alpacas [(25.8±4.7) kg] and four 1-year-old sheep [(28.3±5.8) kg] were used in this study designed as split-plot in two replicated 2×2 Latin square, respectively, and fed diets with different concentrate to corn rubbing stalk ratios [5:5 (MS) and 7:3 (LS)], respectively. The results showed as follows: 1) the dry matter intake of alpaca was significantly lower than that of sheep (P<0.01), and the apparent digestibility of ether extract and phosphorus were significantly higher than those of sheep (P<0.01); the contents of valeric acid, isobutyric acid and isovaleric acid and pH of alpaca were significantly higher than those of sheep (P<0.01), and the content of acetic acid was significantly lower than that of sheep (P<0.05); the excretion of total purine derivatives, uric acid and allantoin had significant differences between alpaca and sheep (P<0.01). 2) The apparent digestibility of crud protein, neutral washing fiber and ether extract of MS diets for alpaca were significantly higher than those of LS diets (P<0.01), and the apparent digestibility of dry matter, organic matter, crude protein and ether extract of MS diets for sheep were significantly higher than those of LS diets (P<0.05); the apparent digestibility of dry matter, calcium and phosphorus of MS diets for alpaca were significantly lower than those of LS diets (P<0.01). The pH and isobutyric acid content of alpaca fed MS diets were significantly higher than those fed LS diets (P<0.01), the propionic acid content was significantly higher than that fed LS diets (P<0.05); the contents of isobutyric acid and isovaleric acid of sheep fed MS diets were significantly higher than those fed LS diets (P<0.01), and the butyric acid content was significantly lower than that fed LS diets (P<0.01); acetic acid/propanoic acid of alpaca fed MS diets was significantly lower than that fed LS diets (P<0.05). The excretion of total purine derivatives and allantoin had no significant differences between two animals (P>0.05), but the excretion of uric acid of alpaca fed MS diets was significantly higher than that fed LS diets (P<0.05). In conclusion, under conditions of corn straw as roughage, there are some differences in the dry matter intake, rumen environment, apparent digestibility and the excretion of total purine derivatives between alpaca and sheep.
