【摘要】：选择20日龄断奶小尾寒羊公羔12只(平均体重5.57±0.36千克),随机分为对照和试验两组(每组n=6)。在自由采食相同饲粮条件下,试验组喂给磁化水,对照组喂给普通水。在95~110和215~230日龄分别进行二次消化代谢试验,并在240日龄进行屠宰性能测定,以研究饮用磁化水对羔羊生长和消化代谢的影响。结果表明,羔羊饮用磁化水在95~110日龄干物质自由采食量、干物质、有机物、粗蛋白、纤维素、半纤维素、钙、磷的(表观)消化率分别提高25.5%、15.2%、14.4%(P0.05)、13.5%(P0.05)、66.3%(P0.05)、52.3%(P0.05)、16.4%(P0.05)和1.3%,在215~230日龄分别提高15.3%、29.4%(P0.05)、25.1%(P0.05)、23.7%(P0.05)、75.2%(P0.05)、52.0%(P0.05)、26.1%(P0.05)和31.7%(P0.05)。饮用磁化水羔羊220天平均日增重提高47.6%(P0.01)。饮用磁化水羔羊的屠宰活体重、胴体重、胴体净肉率、胴体瘦肉重比对照组分别提高40.8%(P0.01)、52.4%(P0.01)、8.8%(P0.01)和66.2%(P0.01)。由本试验得出结论,饮用磁化水可提高羔羊饲粮消化率和日增重,改善羔羊的屠宰性能。
[Abstract]:Twelve male lambs (mean body weight 5.57 卤0.36 kg / kg) were randomly divided into control group and trial group (n = 6). The experimental group was fed magnetized water and the control group was fed with common water under the condition of free feeding on the same diet. In order to study the effect of magnetized water consumption on the growth and digestion of lambs, the secondary digestion and metabolism tests were carried out at the ages of 95, 110 and 215 ~ 230 days, and slaughtering performance at 240 days old, respectively, in order to study the effects of drinking magnetized water on the growth and digestion of lambs. 缁撴灉琛ㄦ槑,缇旂緤楗�鐢ㄧ�佸寲姘村湪95~110鏃ラ緞骞茬墿璐ㄨ嚜鐢遍噰椋熼噺,骞茬墿璐，
