How Much Blood Is in a Cow?

The amount of blood in a cow is dependent upon the cow’s weight; however, it is generally accepted that the blood volume of cattle is an average of 55 milliliters per kilogram. Smaller cows, such as calves, would have less blood than larger cows, such as bulls.

In older animals and obese animals, the amount of blood decreases from the amount of blood that was present when the animal was a healthy adult. The amount of specific components of blood, including plasma, can vary greatly from one species to another. Some components of blood may vary in volume based on the diet of the cow.


Much recent work especially in Germany has been concerned with various anatomical and blood analytical measurements upon milking cows. The physical measurements have been concerned with the size of various portions of the body. The chemical measurements have dealt with such blood constituents as total solids and hemoglobin.

Kronacher and his students have reported many such studies (1). In their earlier papers they found a correlation between the fat of the milk and the total solids of the blood in lactating goats. In their later papers (2) they seem to get no correlations between either the physical measurements or the blood constituents and the productive capacities of cows.

The physical measurements of Kronacher (1) included the height at withers, the depth, width and girth of the breast, the hip width, the width and length of pelvis and the rib angle. The blood constituents and properties that were considered by Kronaeher are hemoglobin, dry substance, blood viscosi~, plasma
viscosity, serum viscosity, erythrocyte sinking rate and alkaline reserve. In both papers Kronacher has called attention to the high positive correlation between the hemoglobin and the total dry substance of the blood.

10.9 ± 0.86 grams of hemoglobin per 100 cc. of blood.

Since the blood data of Kronacher were not convincing, we decided to run monthly hemoglobin determinations upon the blood of the animals in the Cornell University herd for a period of one year. One thousand and seventy-three analyses were made hy the method of Cohen and Smith (3) upon female animals.
These included sixty-nine mature cows and twenty-one other younger animals. The mean of all hemoglobin determinations upon female animals was 10.9 ± 0.86 grams of hemoglobin per 100 cc. of blood.

During the course of the same year seventy determinations were made upon six mature bulls of four different breeds. The mean value for these animals was 12.8 ± 0.8 grams of hemoglobin per 100 ee. of blood. There is a significant difference between the hemoglobin values of the male and female animals. This is the reverse of the findings of Anderson (4), who found females had the higher hemoglobin values.

It accords with long established values upon human blood which show that the normal male has more erythrocytes and more hemoglobin per unit volume of blood than the female. In most animal species the male has more hemoglobin per unit volume of blood than the female. Schulz and Kr~iger (5) have pointed out some exceptions to this rule, however.

Holsteins, Ayrshires, Guernseys, Jerseys

Our cows studied included thirty-eight Holsteins, eight Ayrshires, ten Guernseys, and thirteen Jerseys. The mean for each of these breeds is the same within the experimental error. There is no correlation between breed and the hemoglobin level.

Normally a homekill guy has a small hiab lift that they swing it up with by the heels, they get quartered and the quarters put in the truck.

As to blood volume, an average human is supposed to have 2 Gallons (whether imp or american I can’t remember) so going by 4.5 lt per gallons (american gals, they’re smaller), that is 9 litres or so. “average” seems to be about 75Kg, so a 500Kg cow is 6 to 7 times the size, so by logic ought to have 6 or 7 times the blood. call it 50 litres that’s a lot of black pudding.

The problem with a cow is that it takes 10 to 15 minutes for it to stop kicking after it has been shot and throat cut. Within that time it is very dangerous to be anywhere near the feet. The blood is mostly pumped out within the first 3 to 5 minutes. But, standing by the head is fairly safe, so if you had 4 or 5 10 litre buckets, and rushed in as soon as the throat had been cut, you might manage to catch a fair amount of the blood.

How many Litres of blood is in a buffalo?

245 Liters (65 gal.)

How much blood is in an elephant? Heart and liver: The elephant heart weights 22 kilograms and circulates about 450 litres of blood. Inner ‘cleaning’ is performed by a 77 kilograms liver. Water and trunk: To drink its 9 litres of water at a time, the elephant uses its trunk which weighs 113 kilograms.

Why do slaughterhouses boil blood? Companies use the blood to make a variety of products that can benefit from its nourishing components. Food producers can use it to make blood sausage, or black pudding, which they sell to markets for human consumption. Blood is a life-giving substance, even after slaughterhouses have harvested it from the vein.

What animal has the most blood?

They have a CBV of 86 mL/kg on average, with a range of 79 to 90. Obviously, though, whales have the greatest overall blood volume: 10 tons of blood, 20% of their body weight, is blood.

How much blood is in a sheep?

NOTES: Total blood volume of a sheep is 60 ml/kg or 6.0 % of total body weight (BW). No more than 1% of the animal’s blood volume in one collection or over a 24 hour period.

How much blood is in a human body?

adult will have approximately 1.2-1.5 gallons (or 10 units) of blood in their body. Blood is approximately 10% of an adult’s weight.


Blood samples taken repeatedly from dairy cows on pasture (50 Holstein-Friesian) and then from 181 cows and their newborn calves within 5 to 10 min after birth were used for measurement of haemoglobin content (Hb). Hb decreased with ongoing lactation and pregnancy, increased several weeks before parturition and reached its highest value shortly after birth.

There was some individual, breed and age specificity of Hb in dairy cows. Assisted calvings using marked traction resulted in no difference in Hb values of the cows when compared to other calvings; whereas the calves’ Hb values were smaller and the difference between calf Hb and cow Hb was greater. A strong correlation between Hb of the cow and Hb of the newborn calf and the difference Hb calf-Hb cow could be found.
