Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

Feed conversion ratio (kg feed/kg live wt. gain) in pigs is 3 kg.
In animal husbandry, feed conversion ratio (FCR) or feed conversion rate is a ratio or rate measuring the efficiency with which the bodies of livestock convert animal feed into the desired output.
The FCR of pigs is greatest up to the period, when pigs weigh 220 pounds. During this period, their FCR is 3.5. Their FCR begins decreasing gradually after this period.
Lower FCR values indicate higher efficiency. FCR calculated based on weight gained gets worse after pigs mature, as it takes more and more feed to drive growth.

Suitable pH for fish ponds is 6.5.
An acceptable range would be 6.5 to 9.0, but most suitable pH is 6.5. Fish can become stressed in water with a pH ranging from 4.0 to 6.5 and 9.0 to 11.0.
A higher water pH can become especially dangerous for pond fish, as both high pH and high temperatures will increase the toxicity of ammonia in water.

In milk heat treatment (like pasteurization), vitamins behave differently based on their stability.

Vitamin C is highly heat-sensitive and is easily destroyed.

Vitamin K is generally heat-stable, but it is present in very small amounts in milk and is not the primary consideration in dairy science questions.

Vitamin A is a fat-soluble vitamin and is well-known for its stability during pasteurization and normal heat treatment of milk.

In dairy science and animal husbandry context, Vitamin A is considered the most heat-resistant vitamin in milk.

Therefore, the correct answer is Option A (Vitamin A).

The oestrus cycle of sheep is 16 days.
Sheep oestrus cycles occur seasonally, and the duration of one complete ovarian cycle is 16 - 17 days. Average duration of oestrus is 24 to 36 hours, with ovulation occurring toward the end of oestrus or approximately 24 hours after the onset of oestrus.
The length of 1,038 estrous cycles for 299 different ewes, 90% of the cycles were 14 - 19 days long, with an average of about 17 days. The start of the estrous cycle is considered to be when ovulation of an egg occurs from the ovary.

Cattle plague is another name for Rinderpest.
Rinderpest (also cattle plague or steppe murrain) was an infectious viral disease of cattle, domestic buffalo, and many other species.
Infected animals suffered from symptoms such as fever, wounds in the mouth, diarrhea, discharge from the nose and eyes, and eventually death.
Rinderpest was mainly transmitted by direct contact and by drinking contaminated water, although it could also be transmitted by air.

The viral agent that produces diphagic fever, respiratory distress, nervous symptoms and hard pad disease in dogs is Canine distemper virus.
Canine distemper virus (CDV) (sometimes termed “footpad disease”) is a viral disease that affects a wide variety of mammal families, including domestic and wild species of dogs.
The above signs, especially fever, respiratory signs, neurological signs, and thickened footpads, occurring in unvaccinated dogs strongly indicate CDV. The time between infection and disease is 14 to 18 days, although a fever can appear from 3 to 6 days after infection.

The animal gets swelling on the hind quarters, shoulders arid neck, limp and on pressing the affected parts, making crepitating sound in the disease named Black quarter.
Blackleg, black quarter, quarter evil, or quarter ill is an infectious bacterial disease most commonly caused by Clostridium chauvoei, a Gram-positive bacterial species.
It is an acute, highly fatal disease of cattle and sheep. In cattle, characteristic lesions of emphysematous swelling of the musculature often develop without a history of wounds. When infection begins, the animal may develop a fever, and the affected limb can feel hot to the touch. The limb usually swells significantly, and the animal can develop lameness on the affected leg.

Shortest period of estrous cycle is Estrus.
In species with estrous cycles, females are generally only sexually active during the estrus phase of their cycle.
Estrus refers to the phase when the female is sexually receptive. A signal trait of estrus is the lordosis reflex, in which the animal spontaneously elevates her hindquarters.

β-oxidation can occur in Mitochondria and Peroxisomes.
Beta-oxidation is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA, which enters the citric acid cycle, and NADH and FADH₂, which are co-enzymes used in the electron transport chain.
Mitochondria catalyze the beta-oxidation of the bulk of short-, medium-, and long-chain fatty acids derived from diet, and this pathway constitutes the major process by which fatty acids are oxidized to generate energy.

Salted meat of pig is known as Bacon.
Bacon is a type of salt-cured pork made from various cuts, typically the belly or less fatty parts of the back. It is eaten as a side dish, used as a central ingredient, or as a flavouring or accent.
Bacon is also used for barding and larding roasts, especially game, including venison and pheasant, and may also be used to insulate or flavour roast joints by being layered onto the meat.
