The calf serum is widely used in the vaccine industry. It actually serves to "water" cell cultures in which viruses or microbial particles (antigens) are developed. This calf serum acts as a kind of growth factor that will result in a greater yield.
Of course, this calf serum can not be heated beyond measure may destroy growth factors sought but, on the other hand, without sufficient heating, the risk that the vehicle dangerous pet pavillion prions cow disease crazy (Creutzfeld Jacob) is real ....
To provide 500,000 liters of bovine serum purchased by laboratories worldwide each year, over a million fetal calf must be sacrificed. The laboratories are supplied in New Zealand, Brazil, Mexico, the United States, Australia, Canada, in various countries of Europe, and Africa. pet pavillion Cows come from intensive farming, others are sometimes made pregnant pet pavillion specifically to harvest their fetus, as in Hungary or Slovakia. Technique to recover the blood of the calf may vary and be different in each country, for each plant. It is, in some cases, to remove the blood from the umbilical cord to a puncture or the jugular vein of the fetus. The most widespread technique uses a cardiac puncture. pet pavillion A pregnant cow is killed. In a period ranging from five to thirty minutes depending on the procedures in force in the country concerned, the fetus is removed from the womb of his mother.
The umbilical cord of the calf, which can be between three and nine months is cut. A long needle is inserted directly into his heart still beating. Blood is collected by suction and placed in a sterile bag. The calf is then destroyed. Several countries and laboratories defend taking blood from a heart of a calf alive. But according to a former inspector of the U.S. Department of Agriculture: "For practical reasons, the heart of the calf must still fight to collect a sufficient pet pavillion amount of blood." A Chilean producer of A. Cox Commercial and Industrial Ltd Aprex. is of the same opinion... "The animal is alive when it bleeds Blood should be taken by cardiac puncture from a living animal dies When fetal blood coagulates immediately The heart must still pump to transport the liquid blood out of the body. " By definition, the calf is still alive but received pet pavillion no anesthesia during this painful process. It can feel great pain.
In addition to the ethical considerations of the operation of the animal seen as a product of experience and merchandise, contamination of vaccines and culture media by bovine serum is real and very disturbing. Will he risk in the case of bovine spongiform encephalopathy or "mad cow disease"? It was recognized that the mother can transmit the disease to their offspring pet pavillion in utero, and therefore fetal tissues may carry contamination. Producing pet pavillion countries fetal bovine serum claim that their filtration pet pavillion techniques avoid any risk. However, it is impossible to say in the case of prion. Merchants bovine serum can never certify 100% purity of their products and non-contamination by viral or infectious agents.
There are specific virus in bovine serum: bovine diarrhea virus, herpèsvirus1, parinfluenza3, reovirus, bovine adenovirus, polyomavirus, leukemia virus, etc.. According to several scientific studies these cattle virus contaminated cell cultures and vaccines causing, among other things, cases of gastroenteritis, especially among young children. The virus was detected in bovine diarrhea approximately 30% of human population studied even if it had not had any physical contact with infected animals. According to the work of the researcher pet pavillion R. Harasawa (1995), over 75% of cell lines that were examined soiled with various bovine viruses, cell lines derived from primates proved also contaminated with strains of bovine viruses. It is recognized
