Magnetized Water Improves Digestion and Growth of Lambs

摘要

Twelve of weaned Small-tail Han male lambs,with body weight of(7.99±1.04)kg,at 30 days of age,were divided into two groups to study the effect of drinking magnetized water(MW)on digestion and metabolism of lambs.The voluntary intake and ADG from 30 to 240 days of age were measured,twice of digestion and metabolism trial were carried out,and at the age of 240 days slaughter test was conducted.The results showed that drinking MW significantly increased voluntary feed intake(27.2%),ADG(27.4%)and apparent digestibility of DM(17.9%),OM(20.2%),CP(22.8%),and energy(12.7%),respectively.The nitrogen retention in two experimental trials significantly increased by 43.9%and 28.9%,respectively.Drinking MW significantly increased live body weight(24.5%),carcass weight(28.2%),carcass net meat weight(25.5%),carcass lean weight(32.5%)and carcass fat weight(31.3%),respectively.The fresh weights of liver,kidney,rumen,longissimus dorsi and leg muscle of lambs drinking MW increased significantly,but there was no significant difference in their contents of DM,OM and CP.It is concluded that drinking MW is beneficial for increasing voluntary feed intake,digestibility,and ADG,and improving slaughter performance of lambs.
