| This article studied on the effects of supplemented with healthy adult sheep ruminal fluid preparationson body weight gain and the concentration of plasma immunoglobulin of the lambs and calves from1to35-day-old, and to explore healthy adult sheep rumen fluid preparation to improve newborn lambs, calvesgastrointestinal health, increase the likelihood of weight gain.Experiment Ⅰ: as a model animal, Newborn lambs were supplemented with healthy adult sheepruminal fluid, which contains4kind of components (ruminal fluid supernatant, autoclaved ruminal fluidsupernatant, ultrasonic processing rumen fluid supernatant, autoclaved ultrasonic processing rumen fluidsupernatant). Results showed that: on35d, as compared with control group, weight of lambs in group Ⅰ, II,III and IV increased by12.16%（P＞0.05）and12.61%（P＞0.05）,9.17%（P＞0.05）and11.34%（P＞0.05）respectively;1~35days of age, weight of lambs in group Ⅰ, Ⅱ, Ⅲ and IV during35days washeavier than control group by21.47%（P＞0.05）,22.28%（P＞0.05）,12.34%（P＞0.05）and12.98%（P＞0.05）respectively. serum immunoglobulin levels of lambs in all test groups on28th were higherthan that on14th d by190.81%,157.35%,193.06%,175.06%and160.76%.Experiment Ⅱ: as model animal, Newborn calfs were supplemented with healthy adult sheep ruminalfluid, which contains2kind of components (ruminal fluid supernatant, autoclaved ruminal fluidsupernatant) by oral administration. Experimental results showed that weight and weight gain of calf werenot significant between test groups and control group（P＞0.05） In terms of immune globulin, IgG levelson1st d was higher than that on other days.Then IgG levels tend to be stable. The varying tendency of thecontents of IgA and IgG in plasma were almost identical. Along with the age growth, changes of plasmabiochemical parameters in calves are not consistent with each other. In plasma, total protein, albuminincreased with the age of weeks. However, blood urea and nitrogen were stable in a certain range. |
