[Effects of probiotics additives EM on growth metabolism and immune function of blue fox in growth phase].
Different doses of probiotics EM were added to the diets of blue fox in its growth phase to study the effects of EM additives on its growth, digestion metabolism and immune function. The results showed that with EM additives applied, the ingestion and average daily gains were increased remarkably (P < 0.05). The apparent digest rate of crude fibre, crude protein, mineral elements Ca, P and NPU could be increased (P < 0.05) and correlated with its dose, and the digest rates of the later four targets in group III were increased by 8.21%, 16.27%, 9.82%, and 12.13%, respectively. EM additives could not increase the digest rate of ether extral and N-free extract. Disease of diarrhoea and blood in stool could be prevented and cured, and immune function and the survival rate of fox in growth phase could be increased remarkably. EM, which a kind of efficient, safe and environmental protection additives, can be extended and applied in farming of fur animals.
