The quality of the egg can be judged by Candling.
Candling is a method used in embryology to study the growth and development of an embryo inside an egg. The method uses a bright light source behind the egg to show details through the shell and is so-called because the sources of light used were candles.

Horse is not susceptible to vesicular exanthema virus.
Vesicular exanthema is an acute, febrile disease of swine characterized by the formation of vesicles on the snout, tongue, and teats, within the oral cavity, and on the feet (between the claws and on the coronary band).
Healthy horses are more disease resistant, so provide good nutrition, regular exercise, deworming and routine vaccinations to prevent such diseases.

Gerber method is used for Fat testing.
The Gerber method consists of separating and measuring the fat contained in milk or its derivatives. It was developed in 1892 and is still used for its speed and accuracy. The fat percentage scale of the products to which this method is applied is between 0 and 16% fat.

Merino wool's have 80% share in world.
The Merino is a breed or group breeds of domestic sheep, characterized by very fine soft wool. A Saxon Merino produces 3 - 6 kg (6.6 - 13.2 lb) of greasy wool a year, while a good quality Peppin Merino ram produces up to 18 kg (40 lb).
The world's best Merino wool comes from Australia, which provides 80% of the world's superfine wool, from woolgrowers who employ sustainable farming practices.

Ongole is a breed of Cow.
Ongole cattle is an indigenous cattle breed that originates from Prakasam District in the state of Andhra Pradesh in India. The breed derives its name from the place the breed originates from, Ongole.
The weight of an Ongole female is 432 to 455 kg. Milk yield is 600 kg to 2518 kg. The lactation period is 279 days. Ongole milk has a butterfat content of over five percent. This results in large, well-nourished calves with considerable growth by the time of weaning.

Constant presence of a disease or organism in an Endemic community.
An endemic disease always has a steady, predictable number of people getting sick, but that number can be high or low, and the disease can be severe or mild.
In a specific population or populated place when that infection is constantly maintained at a baseline level without extra infections being brought into the group as a result of travel or similar means.

Yellow colour of cow milk is due to presence of Carotene.
Milk is an emulsion or colloid of butterfat globules within a water-based fluid that contains dissolved carbohydrates and protein aggregates with minerals.
Cow milk is slightly yellow in comparision with bufflo milk due to the presence of carotene. The fat globules contain some yellow-orange carotene, enough in some breeds (such as Guernsey and Jersey cattle) to impart a golden or "creamy" hue to a glass of milk.

The heat period of buffalo is 12 - 36 h.
The heat cycle of the female lasts from 18 to 21 days. The first stage is called proestrus. It begins with mild swelling of the vulva and a bloody discharge.
The mean length of the oestrous cycle is 21 days, with greater variation than observed in cattle. The signs of oestrus in buffalo are less overt than in cattle and homosexual behaviour between females is rare. The duration of oestrus is 5 - 27 h, with ovulation occurring 24 - 48 h (mean 34 h) after the onset of oestrus.

Mycoplasma organisms are pleomorphic due to absence of rigid cell walls.
Mycoplasma is a genus of bacteria that lack a cell wall around their cell membranes. Peptidoglycan (murein) is absent. This characteristic makes them naturally resistant to antibiotics that target cell wall synthesis. They can be parasitic or saprotrophic.
Due to the absence of cell walls these organisms can change their shape and are pleomorphic as they cannot be identified as rods, cocci or spirochetes.

Blue revolution is related to Fisheries.
The Blue Revolution refers to the significant growth and intensification of global aquaculture production -domestication and farming of fish, shellfish, and aquatic plants- from the middle of the 20^th century to the present, particularly in underdeveloped countries.
The Blue Revolution has improved accessibility and availability of farmed fish in some regions, therefore potentially improving food and nutrient security, especially in low-income nations and rural populations.
