Size of the calving box is 100 - 150 sq ft.
A calf box or igloo is an effective accommodation system that helps you prevent contamination between calves and allows you to properly monitor feed consumption in the first few weeks after birth.
An individual loose box or stall used for calving should be 100 - 150 sqft and well-ventilated. Sufficient lighting is essential. It provided better protection to the cow and calf and avoids disturbances from other cows.

The condition of persistent hymen is known as White heifer disease.
A congenital reproductive abnormality in white female offspring (heifers) in certain breeds of Cattle. The white colour is inherited as a recessive trait that is associated with defects in the female reproductive tract (Muellerian system).

Cobalt is mainly found in Vitamin B₁₂.
Cobalt is a core element of vitamin B₁₂ (cyanocobalamin), which is essential for the prevention of anemia in humans. Ruminant animals such as cows, sheep, goats, deer and camel produce vitamin B₁₂ if there is adequate Co in their diet.
Sources of Vitamin B₁₂. Vitamin B₁₂ is naturally present in foods of animal origin, including fish, meat, poultry, eggs, and dairy products.

Knott's technique is a concentration method for the detection of Microfilariae parasites in blood.
This technique is used to recover low numbers of microfilariae from blood. A solution is used to lyse the RBCs in a large blood sample, and the organisms are concentrated from the supernatant fluid by centrifugation.
It is easy to perform, rapid and inexpensive, it conserves mf morphology and size, and it enhances the sensitivity of mf detection in blood samples.

Mating of a cross-breed animal back to one of the pure parents is Back crossing.
Backcrossing is a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, to achieve offspring with a genetic identity closer to that of the parent. It is used in horticulture, animal breeding, and the production of gene knockout organisms.
Backcrossing may be deliberately employed in animals to transfer a desirable trait in an animal of inferior genetic background to an animal of preferable genetic background.

Lactose is a disaccharide made of Galactose and glucose.
Lactose is a disaccharide sugar synthesized by galactose and glucose subunits and has the molecular formula C₁₂H₂₂O₁₁. Lactose makes up around 2 - 8% of milk.
The compound is a white, water-soluble, non-hygroscopic solid with a mildly sweet taste. It is used in the food industry.

The cells parasitized in host by Rickettsia are vascular endothelial cells.
Rickettsia is a genus of nonmotile, gram-negative, nonspore-forming, highly pleomorphic bacteria.
These are obligate intracellular parasites that invade vascular endothelial cells in target organs, damaging them and producing increased vascular permeability with consequent oedema, hypotension and hypoalbuminaemia.

It made India the world's largest milk producer, doubled the milk available for each person, and increased milk output fourfold in 30 years.

The chromosome number of the swamp buffalo is 48.
The diploid number of chromosomes of the water buffalo was found to be 48. The autosomes consisted of 5 meta- or submetacentric and 18 acro-centric chromosome pairs and two acrocentric sex chromosomes.

Curled toe paralysis is caused due to deficiency of Vitamin B₂.
Curled toe paralysis is a low riboflavin diet that may cause two types of nutritional deficiency. One of these produces a rapidly acute paralysis characterized as neuromalacia and a more slowly developing form that causes 'curled toe' paralysis in the growing chick.
The signs and symptoms of riboflavin deficiency include skin disorders, hyperemia and edema of the mouth and throat, angular stomatitis, cheilosis, hair loss, reproductive problems.
