In pigs, for example, blood makes up around 3.3% of live weight, which generally yields about 2.5L per animal.
The average pig has about three or three and a half liters of blood.
Are pigs 80% blood? No mammals are 80% blood. We all have bones, muscles, and guts that take up nearly that much percentage of our weight.
They're blood actually is quite similar to human blood. The size of red blood cells is similar. So is the typical red blood cell life span, the hemoglobin content and structure, and other factors, plus pigs can be genetically modified to produce red blood cells that are equivalent to human type O negative.
In pigs there are only A and O alleles, so there can only be two blood types, A and O. Genetic analysis has shown that the porcine A gene is homologous to the ABO genes in humans and other species. It encodes an α1→ 3 N-acetyl-D-galactosaminyltransferase that synthesizes A antigens.
Pig blood protein has a higher nutritional value than any other plant or dairy-based protein now on the market. The protein is transformed into a white, neutral-tasting powder that can be used in a variety of foods.
Pigs express antigens that correlate with human A or O blood group antigens, but only blood group O pigs are used in the field of xenotransplantation [36]. Pigs have a single Rh gene that does not appear to represent a blood group antigen [139].
"Depending upon what it is that you are comparing you can say 'Yes, there's a very high degree of similarity, for example between a human and a pig protein coding sequence', but if you compare rapidly evolving non-coding sequences from a similar location in the genome, you may not be able to recognise any similarity at ...
Monkeys and apes have been shown to have blood types comparable, although not identical, to the human ABO blood group system.
A heart doctor has given a patient a transfusion of pig's blood in an operation that may pave the way for animal-to-human organ transplants. Dr. Dhaniram Baruah, a London surgeon, injected more than half a pint of the blood into a man suffering from severe anemia.
Based on that thinking, researchers imagined that about 9000 years ago, humans corralled a few wild boars and—by separating them from their fellows and breeding them for favorable traits like tameness, size, and meatiness—they developed the domesticated oinkers that we see all over the world today.
The heart is located in the thoracic cavity nestled between the lungs on the body's midline. Pigs like other mammals have a four-chambered heart. The right side of the heart pumps blood to the lungs (pulmonary circulation), and the left side pumps blood out to the rest of the body (systemic circulation).
For pork blood to be certified "edible," FSIS requirements include that blood come from healthy animals (inspected before and after slaughter), be processed in an establishment under official control and be heat-treated. Pig blood also must come from a country free of classical swine fever.
The amount of blood in a person's body will depend on their age and size, but it is around 7–8% of an adult's body weight. A person can lose around one pint without causing any harm to the body. According to an older review article in Critical Care , blood accounts for: approximately 7–8% of an adult's body weight.

Blood is removed from beef during slaughter and only a small amount remains within the muscle tissue. Since beef is about 3/4 water, this natural moisture combined with protein is the source of the liquid in the package.
Cows have 800 (and possibly more) blood types. The most common blood type in the United States is O Positive (39% of the population), while the least common blood type is AB negative with only (0.5% of the population).
AB negative is the rarest of the eight main blood types - just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don't struggle to find donors with AB negative blood. However, some blood types are both rare and in demand.
In molecular history, type A appears to be the 'oldest' blood type, in the sense that the mutations that gave rise to types O and B appear to stem from it. Geneticists call this the wild-type or ancestral allele.
The domestic pig originates from the Eurasian wild boar (Sus scrofa). We have sequenced mitochondrial DNA and nuclear genes from wild and domestic pigs from Asia and Europe. Clear evidence was obtained for domestication to have occurred independently from wild boar subspecies in Europe and Asia.
While it is true that human and pig DNA and certain aspects of our biochemistry are fairly similar given our large anatomical differences (I haven't seen a human with trotters yet), it's not due to a close phylogenic relationship, but rather an example of convergent evolution.
We know chimps and bonobos share 99% of our genes. More startling is an even newer discovery: we share 99% of our DNA with lettuce. This could have startling philosophical, scientific and medical implications.
People going on the blood type O diet should also keep away from certain types of meat and seafood, and most dairy products. This is because they include hard to digest animal protein. Such meat includes pork, ham, bacon, goose, octopus, caviar, smoked salmon, milk, and milk-based goods such as yogurt and ice-cream.
Although there needs to be additional studies on the topic, some scientists are favoring Sus scrofa domesticus (pigs) as a source of blood for transfusions after having tested many different animals in order to find the best candidate for a blood donation.
Human-animal hybrids, also known as 'chimeras', are creatures with a mixture of human and animal cells. They are created by injecting human stem cells into the embryo of another animal. So far, no human-animal hybrid embryos have been brought to term ('term' means full gestational period).
