Question

Bypass fat 84% vs bypass fat 99%

Stephen Christiaan Slippers · Accepted Answer

Vijay,

Bypass fat 84% is likely a calcium soap of palm fatty acid distillate, and would also contain 8-9% calcium. The fatty acid profile is dominated by long chain fatty acids, particularly C18:0 (stearic acid). Used as energy source in dairy cow diets, to support body weight gain and higher milk yield. High inclusion levels or sudden introductions in feed can cause adverse effects on DMI, but pellet quality is not adversely affected by inclusion of calcium soaps.

Bypass fat 99% is likely a fractionated fat, with a particular fatty acid profile, for example dominated by C16:0 (palmitic acid). High-palmitic bypass fats are used to supply preformed fatty acids to the mammary gland, for incorporation into milk fat. Thus helps to keep milk fat concentrations and yield at higher levels, for instance when hot weather would otherwise cause lower milk fat concentrations. Does not affect DMI, but inclusion rates in pelleted feeds should be restricted to prevent soft pellets.

Hope this is helpful.

Regards.
