The Effect Of The Feeding Pellet Diet And Supplementing Aerosol OT On The Intake,Digestion And Metabolism Of Sheep

Four of 2 year’s-old male Small-tail Han non-pregnant ewe, with body weight of50.19±2.3 kg, were supplemented with aerosol OT(0 or 0.8 g/kg of diet) under the circumstance of feeding ground diet and pellet diet, by the Latin square experiment of4×4, to study the effect of supplement of aerosol OT on the voluntary intake,digestion and metabolism of sheep under two diets above. The results showed that in the condition of ground diet the supplement of aerosol OT to sheep increased the voluntary intake by 8.1 %(P<0.05),the apparent digestibility of the dry matter,organic matter, crude protein, cellulose, hemicellulose, calcium, phosphorous were increased by 4.8 %(P<0.01),4.7 %(P<0.01),4.8 %(P<0.01),4.7 %(P<0.01),4.8 %(P<0.01),-15.1 %(P<0.01),4.8 %(P<0.01)respectively, the digested amounts were increased by 13.3 %(P < 0.01),14.1 %(P < 0.01),13.3 %(P <0.01),13.3 %(P < 0.01),13.3 %(P < 0.01),13.6 %(P < 0.01),13.5 %(P <0.01),12.9 %(P<0.01)respectively, nitrogen retention was increased by 8.4 %(P<0.01). When pellet diet was fed, the voluntary intake of sheep was increased by65.1 %(P<0.01), and the digestibility of dry matter was decreased by 13.8 %(P<0.01). However, when the pellet diet was fed, the supplement of aerosol OT had no significant effect on the voluntary intake, digestibility of diet, and nitrogen retention of sheep.
