Effect of Substitute High Immunoglobulin SDWE for SDPP on Performance of Weaned Piglets;

Furthermore, a certain amount of SDPPwas produced to research its effects on early-weaned piglet.

Further more, a certain amount of SDPP was produced to research its nutritional effects by piglet-raising experiment.

This paper summarizes the characteristics of Spray-dried plasma protein and spray-dried animal blood cells and the applied effection to early-weaned pigs.

36 early weanling pigs of age in 35 days were selected and divided into two groups(control group and test group),and the effects of plasma protein flour prepared by spray drying on the growing performance of weanling pigs and biochemical indexes of blood were researched.

The influences of incoming air temperature (200, 230, 260℃) and exhaust air temperature (70, 80, 90℃) of spray drying on various indexes such as nitrogen dissolving index, crude protein, yield and moisture of plasma protein flour immunoglobulin were investigated.

Effects of different levels of spray-dried porcine plasma on growth performance and immune function in broilers;

Different protein sources(spray-dried blood plasma albumen powder,spray-dried hemocyte albumen powder and milk substitute) were used in the feed for suckling piglets(age in 7～30 days),which all influenced the incidence of yellow and white flux,survival rate,gain and feed conversion for piglets.
