The Effect Of Drinking Magnetized Water(MW)on The Digestion And Metabolism Of Sheep Fed Pellet Diets

In the experiment 1,Selected four small-tail sheep weighing about 1.5 years old and weighing 44.7 ± 1.8kg were designed with 4 × 4 Latin square design and free to feed the same composition(oncentrate:roughage=4:6)(1: ground diets;treatment 2: pellet diets + magnetized water;treatment 3: ground diets;treatment 4: pellet diets + magnetized water)(n = 4),digestion and metabolism and to study the effects of drinking magnetized water on the feeding and digestion and metabolism of sheep under two dietary conditions.In order to reduce the digestibility of sheep in the free-feed pellets found in experiment 1,six small-tailed Han sheep with about 1.5 years of age and weighing 46.31 ± 2.1 kg were selected to feed the same pellet day as test 1 pellet diets,with 3 × 3 Latin square design,treatment 5: voluntary intake,treatment 6: voluntary intake + magnetized water,treatment 7: restricted feeding + magnetized water to study the limit of dietary diets when drinking magnetized water on sheep digestion and metabolism.The contents of dry matter,organic matter,crude protein,cellulose,hemicellulose,calcium,phosphorus,energy and the enzyme could degrade cellulose and hemicellulose in the samples were analyzed for the excrement of dung,urine and residual material in experiments 1 and 2.The results showed that in experiment 1: the voluntary intake of pellets fed with ground diets were increased 51.6% than that of the ground diets(P<0.05),but the apparent digestibility of dry matter,organic matter and crude protein were reduced 19.6%(P<0.01),16.5%(P<0.01),3.8%(P<0.05)respectively;voluntary intake under the ground and pellet diet condition of drinking magnetized water,free voluntary intake of sheep were increased 14.3%(P<0.05)and 14.7%(P<0.05)respectively,nitrogen retention were increased 22.7%(P<0.01)and 14.2%(P<0.05)respectively,the digestibility of non-enzyme-hydrolyasable cellulose were increased 19.7%(P<0.01)and 23.4%(P<0.01)respectively,the digestibility of non-enzyme-hydrolyasable hemicellulose were increased 23.8%(P<0.01)and 21.3%(P<0.01)respectively,but the apparent digestibility of dry matter were increased 2.6%(P>0.05)and 4.2%(P<0.05)respectively,the apparent digestibility of crude protein were increased 2.2%(P>0.05)and 4.8%(P<0.05)respectively,the apparent digestibility of energy were increased 2.2%(P>0.05)and 6.0%(P<0.01)respectively.In experiment 2: voluntary intake pellet diets + magnetized water,restricted feeding pellet diets than free feed pellet diets processing digestive volume of dry matter high 24.9%(P<0.01)and 16.3%(P<0.01)respectively,nitrogen retention were increased 25.4 %(P<0.01)and 14.8%(P<0.01)respectively,the digestibility of non-enzyme-hydrolyasable cellulose were increased 33.4%(P<0.01)and 4.4 times(P<0.01)respectively,the digestibility of non-enzyme-hydrolyasable hemicellulose were increased 31.8%(P<0.01)and 3.3 times(P<0.01)respectively,the apparent digestibility of dry matter were increased 7.2%(P<0.05)and 19.1%(P<0.01)respectively,the apparent digestibility of crude protein were increased 4.9%(P<0.05)and 19.0%(P<0.01)respectively,the apparent digestibility of energy were increased 5.7%(P<0.05)and17.4%(P<0.01)respectively,The results showed that the digestibility of sheep fed with pellet diet was significantly reduced,and after drinking magnetized water has a tendency to increase digestibility,suggesting that magnetized water to a certain extent,ease the feeding of pellets diet to the increase in voluntary intake and reduce the digestibility of the adverse situation;restricted feeding of pellets diet and drinking magnetized water can significantly improve the apparent digestibility of dietary dry matter,drinking magnetized water can increase the nutrient supply by increasing the apparent digestibility.
