Colostrum prevents Calf scours, Night blindness, and Navel ill.
Colostrum is the perfect first food for the newborn. It has significant advantages for newborns and mothers. It contains antibodies such as IgA, IgG, and IgM that protect against bacterial, viral, and fungal infections.
It contains immunoglobulins produced by the cow's immune system and protects the calf against diseases present in the herd.
Lutein is one of the reasons colostrum (first milk expressed during breastfeeding) is yellow and is rich in vitamin A, which helps against night blindness.
Navel ill infections can be prevented by adequate navel treatment in calves and adequate passive antibody transfer through colostrum.

Bursa of fabricus opens in Proctodeum part of the cloaca in birds.
The bursa of Fabricius is a blind, lymphoepithelial diverticulum of ectodermal origin, located in the dorsal proctodeum of the avian cloaca.
The bursa of Fabricius is the primary lymphoid organ in avian species. The bursa of Fabricius of birds has an essential role as a central lymphoid organ for the differentiation of B lymphocytes. In addition, the bursa harbors immune competent B lymphocytes which are capable of local antibody production.

The average yield of fine wool by chokla is 2.5 - 3.5 kg/Annum.
Chokla sheep grows the finest carpet wool of all the Indian breeds ranging in quality number from 54 s to 60 s count. The wool produced by Chokla sheep is heterogeneous and is generally mixed with coarser fleece of other sheep before utilization as carpet wool.
It produces 2.4 kg wool per annum with average fiber diameter of around 30 m and medullation of around 30%. The staple length of more than 6.0 cm makes it ideally suitable for carpets.

a. The gestation period of cows is 282 days.
282 days is the average gestation period for cows with about equal chances for calving on any day from the 275^th to the 287^th day after service.
b. The gestation period of Buffalo is 307 days.
Average calving interval of these buffaloes is 18 months with gestation period of 307 days.
c. The gestation period of Goat is 151 days.
Gestation length in goats is 145 - 155 days (average 150 days) and can be affected by breed, litter weight, environment, and parity.
d. The gestation period of Sheep is 150 days.
In sheep, although the normal gestation length is 144 - 150 days, the exact gestation length is seldom known unless ewes were served in hand or by artificial insemination.

Dohle's bodies are toxic granules of Neutrophils.
Dohle bodies are light blue-grey, oval, basophilic, leukocyte inclusions located in the peripheral cytoplasm of neutrophils. They measure 1-3 μm in diameter.
They are often present in conjunction with toxic granulation. However, it has been found that certain healthy individuals may have persistent Dohle bodies found in neutrophils.

The causative agent of hydatidious is Echinococcus granulosa.
Hydatid disease (also known as hydatidosis or echinococcosis) is a potentially serious, sometimes fatal, condition caused by cysts containing the larval stages of the Echinococcus granulosus (E. granulosus) tapeworm (Dog Tapeworm).
Human echinococcosis is caused by the larval stages of cestodes (tapeworms) of the genus Echinococcus.

Following are the morbilli viruses except Mumps virus.
Mumps virus is a paramyxovirus not mobilli virus and is spread from person to person via infected saliva.
Morbillivirus is a genus of viruses in the order Mononegavirales, in the family Paramyxoviridae. Humans, dogs, cats, cattle, seals, and cetaceans serve as natural hosts. This genus includes seven species.
Morbillivirions are enveloped, with spherical geometries. Their diameter is around 150 nm. Genomes are linear, around 15 - 16 kb in length. The genome codes for eight proteins.

The average fat, percentage in cow milk is about 4.2%.
The fat content of milk is the proportion of milk, by weight,   made up of butterfat. The fat content, particularly of cow's milk, is modified to make a variety of products.
The fat content of the raw milk produced by cows ranges from about 3.3% up to 5%. It varies by breed, and by diet, and can also be altered by selective breeding and genetic modification.

The main chemical mediator of inflammation is Histamine.
Histamine is a chemical found in some of the body's cells and causes many of the symptoms of allergies, such as a runny nose or sneezing.
Histamine is a potent inflammatory mediator, commonly associated with allergic reactions, promoting vascular and tissue changes and possessing high chemoattractant activity.

The largest gland in the body of fowl is Liver.
In avian species, the liver is larger than in mammals when compared to body size. The size and colour of the liver depend on age and body weight.
The avian liver has much less connective tissue than the mammalian liver and it lacks a true lobular structure.
The liver is a large organ in the abdomen that performs many important bodily functions, including blood filtering. It is also considered a gland because it makes chemicals the body needs.
