Question

The yellow-colored milk secreted by cattle soon after the birth of a calf is called as
A. Chyme
B. Chyle
C. Cholesterol
D. Colostrum

Answer 1

Hint: Colostrum is the first form of milk produced by the mammary glands of mammals immediately after birth.
The colostrum is also known as the first milk.
It is loaded with nutrients and antibodies.

Complete answer:
It is yellow in color in all mammals.
Antibodies in the colostrum provide the calf with initial protection.
A newborn lacks many antibodies for protection against diseases as they do not pass through the cow’s placenta to the fetus’ placenta.
Ideally, within 30 mins of birth, the calves need colostrum about 5% of their body weight.
It is important to feed the calf with colostrum as soon as possible because after 24 hrs the intestine cannot absorb the antibodies intact.
The absorbed antibodies will protect the calf against harmful microorganisms and pathogens and if they are not absorbed they may lead to various intestinal diseases.
The most efficient method of feeding the calf is through the dam.
In some cases, this may be a problem as there may be problems with the dam.
In such cases, the calf needs to be fed manually by first storing the colostrum.
Colostrum is stored by freezing it in milk cartons or plastic containers.
Rapid defrosting can also be used as an alternative method
The acquired colostrum should be from a healthy cow to avoid any disease transmission.
Yellow in color and thick in consistency are indicators of good colostrum.
Cows in their third lactation are good colostrum providers.
A commercially available or supplement colostrum should also be stored if we do not acquire natural colostrum.

Hence the correct answer is option (D).

Note:
Chyme is an acidic fluid that passes from the stomach to the small intestine consisting of gastric juices
Chyle is a milky fluid that contains fat droplets that drain from the lacteals of the small intestine into the lymphatic system.
Cholesterol is a fat-like substance made from lipids found in cells in your body. It is both good and bad for the body. It is needed for the formation of some hormones and essential substances in the body.
