摘      要：Background:The present study aimed at investigating the influence of 90%menthol-containing plant bioactive lipid compounds(PBLC,essential oils)on growth performance,blood haematological and biochemical profile,and nutrient absorption in ***-four growing Suffolk sheep were allotted into three dietary treatments:Control(without PBLC),lower dose of PBLC(PBLC-L;80 mg/d)and higher dose of PBLC(PBLC-H;160 mg/d).Sheep in all groups were fed meadow hay ad libitum plus 600 g/d of concentrate pellets for 28 ***:Average daily gain was not affected by *** of PBLC increased hay and total feed intake per kg body weight(P0.05).Counts of total leucocytes,lymphocytes and monocytes were not different among ***,neutrophil count decreased(P0.05)in PBLC-H with a similar trend in PBLC-L(P0.10).Concentrations of glucose,bilirubin,triglycerides,cholesterol,urea and magnesium in serum were not different among sheep fed different doses of ***,serum calcium concentration tended to increase in PBLC-H(P0.10)and serum concentrations of aspartate&asparagine(P0.01)and glutamate&glutamine(P0.05)increased linearly with increasing PBLC *** ruminal epithelia isolated from the rumen after killing,baseline conductance(Gt;P0.05)and short-circuit current(Isc;P0.01)increased in both PBLC *** uptakes of glucose and methionine in the presence of Na+were not affected by the dietary PBLC *** the absence of Na+,however,glucose and methionine uptakes increased(P0.05)in *** the jejunum,Isc tended to increase in PBLC-H(P0.10),but baseline Gtwas not *** uptakes of glucose and methionine were not influenced by PBLC in the presence or absence of Na+.Conclusion:The results suggest that menthol-rich PBLC increase feed intake,and passive ion and nutrient transport,the latter specifically in the *** also increased serum concentrations of urea precursor amino acids and tended to increase serum calcium
