Changes of parameters in blood,abomasal fluid and rumen fluid in experimental LDA dairy cows;

Rumen liquor was collected from 3 dairy cows before morning feed and divided into eleven groups,including the control group based on the basal diet,five Daidzein groups and five Genistein groups(with the level of 20,40,60,80 and 100 mg/kg respec.

Study on Lactobacillus plantarum ANCLA 01 fermente rumen fluid with the sunflower oil addition in vitro,it can improve the production of conjugated linoleic acid.

Three crossbred wethers fitted with permanent rumen fistula were chosen to measure the effects of different processed diet on rumination and metabolic parameters of rumen fluid in sheep.

01);the concentration of the protozoan protein content of the rumen liquid control stage was 0.

In order to study the influence of diet levels of minerals on the contents of minerals in blood and rumen liquid,three karakul sheep with having permanent fistulas on belly were chosen to analyze the contents of the minerals in rumen liquid and blood at 0d,5d,9d,12d after feeding diet to which Ca,Mg,Fe,Mn,Cu,Zn were added,respectively.
