To study the orderliness of absorption,excretion,retention and metabolism of metallothionein in dairy cattle,twelve male Chinese Holstein calves were treated with 125I labelled metallothionein(125I-MT) given in milk.

To study the orderliness of absorption,excretion,retention and metabolism of metallothionein in dairy cattle,twelve male calves were treated with a method of 125I labeling metallothionein(125I-MT) affused through mouth.

Determination of holdup by air purge in 50 mm discs and doughnuts pulsed extraction column;

The effects of the operation parameters such as pulsed amplitude,pulsed frequency,flow velocity and flow ratio,and the plate spacing on the hydrodynamics characteristics of flooding throughout,flooding-holdup and disperse phase holdup in normal operation were studied through a 100 mm discs and doughnuts pulsed extraction column in 1 mol/L HNO_3 solution-30%TRPO-kerosene solution system.

Effect of vitamin B_6 status on selenium retention in the tissues in rats fed selenium from sodium selenate;

This paper proposes the method of monitoring the k-nearest neighbors,which adopts a predicted-speed policy and a bottom-up update R-tree index with an update firstly stored in memory.

A nitrogen balance trial for Taihe silky fowl was conducted to study the effects of dietary methionine levels on nitrogen retention rate.

360 AA poult were selected to study effect of crust protein hydrolysats on growth of broilers and nitrogen retention rate, adopt single factor repeat test design.

Three nitrogen balance tests were conducted with 180 female Shaoxing ducklings or growing ducks during 0~ 4 wk, 5 ~ 12 wk and 13 ~ 18 wk of age respectively to investigate the effects of 9 isocaloric diets in different crude protein (CP) series on the nitrogen retention rate (NRR).
