“It is common practice to impregnate her one last time, and send her to slaughter when she is about eight months pregnant or so, for the extra profit that her unborn fetus can bring at the slaughter-plant. So after hanging her upside down and slitting her throat so that she dies by the slow and painful death of being bled out, workers cut her open and perform a late-term abortion, stabbing her unborn calf because of the extra profit this calf brings to the industry in three ways:

First, the skin of unborn calves can be used to make fine leather (slink leather) that fetches a higher price.

Second, the stomachs of these unborn calves have already started to produce rennin, the hormone substance that we don’t have that breaks down the main protein in cow milk, casein, and this rennin is used by the cheese industry to coagulate milk to make cheese.

Third, the pharmaceutical industry wants to use the “fetal bovine serum” that is in the calf’s heart and circulatory system for their vaccines, and so workers insert a long needle into the beating heart of the calf to extract this substance, before slitting his or her throat.” via ~ Will Tuttle
