磁化水对6月龄肉牛生产性能及血清指标的影响
Effect of magnetized water on production performance and serum indexes of six-month-old beef cattle
摘要
Abstract
The purpose of the study was to study the effect of magnetized water on the production performance and serum indexes of six-month-old beef cattle.A total of 212 Simmental cattle approximately six months old and weighing about 300 kg were randomly divided into two groups,the control group(110 cattle)drank ordinary water,and the experimental group(102 cattle)drank magnetized water.The test period was 87 days.The results showed that compared with ordinary water,the pH value of magnetized water increased by 7.91％,the total hardness and oxygen consumption decreased by 0.36％and 13.70％,and the total number of colonies and E.coli before and after magnetization were both zero.Compared with the control group,the average daily feed intake in 10 days and average daily gain in the experimental group increased by 4.41％and 5.36％,respectively(P＞0.05).Compared with the control group,the activities of superoxide dismutase and catalase in the experimental group increased by 32.82％(P＜0.05)and 73.36％(P＜0.01),respectively,and the content of malondialdehyde decreased.The concentrations of immunoglobulin A,immunoglobulin G,and immunoglobulin M increased by 13.85％,3.21％,and 5.99％,respectively.Serum urea nitrogen content increased by 30％(P＜0.05).The total protein content decreased by 34.53％(P＜0.0l).The serum levels of insulin,growth hormone,and growth hormone-releasing hormone increased by 10.73％,13.00％,and 5.04％,respectively.Studies have shown that water quality changes after it is magnetized.The magnetized water can increase feed intake and body weight,and enhance serum antioxidant levels,immunity and growth-related hormone levels of beef cattle.关键词
