Virus having RNA dependent DNA polymerase Retrovirus.
Retroviruses are ssRNA viruses that replicate through a DNA intermediate, thus requiring a virus-encoded RNA-dependent DNA polymerase (reverse transcriptase).
Hepatitis B virus is a dsDNA virus that replicates through an RNA intermediate using a virally encoded reverse transcriptase.

Hens usually moult in Head, Neck, Body, Wing, and tail order.
Moulting takes place in a fairly definite order. Feathers are confined to definite tracts or areas of the body surface, with bare patches of skin between.
The first plumage is lost from the head and neck, then from the saddle, breast and abdomen (body), then the wings and then from the tail.

Milk sugar is Lactose.
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 (by mass).
Lactose is a disaccharide derived from the condensation of galactose and glucose, which form a β-1→4 glycosidic linkage.
The lactose content of dairy products can vary depending on the type of product and the specific brand or variety.

The uterine glands secrete 'Uterine milk' under the influence of estrogen and progesterone hormone, composed of Protein, Fat and Glycogen.
Uterine milk is part of the embryotroph. It is a white secretion containing proteins and amino acids that nourish the embryo during development. The uterine milk is the actual nutritional liquid that feeds the embryo, while the embryotroph is the uterine milk plus the syncytiotrophoblast.
The uterine milk proteins (UTMP) are the major proteins secreted by the endometrium, primarily under the control of progesterone.

Spinose ear tick is mainly pathogenic in Larval stage, Nymphal stage and Adult stage.
Otobius megnini, also known as the spinose ear tick, is a soft-bodied tick that is only parasitic in the larval and nymphal stages. As its common name suggests, the spinose ear tick's parasitic forms are usually found within the ears of the definitive host.
Spinose ear ticks are a constant source of annoyance and irritation for their definitive hosts. Their tendency to occur in large numbers can cause ulceration of the inner ear, high sensitivity of the ears, large amounts of blood loss, and even deafness.

a. Anthrax is caused by Bacteria.
Anthrax is an infection caused by the bacterium Bacillus anthracis. It can occur in four forms: skin, lungs, intestinal and injection.

b. Marek’s is caused by Virus.
Marek's disease is a highly contagious viral neoplastic disease in chickens. It is named after Jozsef Marek, a Hungarian veterinarian who described it in 1907. Marek's disease is caused by an alphaherpesvirus known as "Marek's disease virus" (MDV).

c. Mycotic abortion is caused by fungi.
Aspergilli were associated with approximately 5% of all abortion cases and 71% of 446 cases that were cultured for fungi and diagnosed as mycotic abortion.

d. Trycomoniasis is caused by Protozoa.
Trichomoniasis is a common sexually transmitted infection caused by a parasite.

The optimum body weight of pig for pork production is 45 - 90 kg.
Pigs convert inedible feeds, forages, certain grain byproducts obtained from mills, meat by products, damaged feeds and garbage into valuable nutritious meat. Most of these feeds are either not edible or not very palatable to human beings.
A breeding boar requires 2 - 2.5 kg concentrate per 100 kg weight depending on the age, condition and breeding demand.

Oat cereal has more lysine content.
Oats are rich in lysine content compared to other cereals while they have rather lower content of glutamic acid and prolamin.
Lysine is highly metabolically available from milk and moist cooked oats. However, dry cooking of oats reduces lysine MA considerably. The protein quality of cereal-based diets is dependent on the lysine content and bioavailability of the individual foods.
