Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

The system of housing cattle, which costs less saves labour and provides more comfort to the animal is loose housing system.
A system of housing in which animals are kept loose in an open paddock in groups of 40 - 50 throughout the day and night.
The loose housing system involves low cost of construction and maintenance, provides more comfort to animals, and ensures easier detection of oestrus and better labour efficiency, as compared to the conventional housing system.

A good quality dahi should have acidity of less than 0.8%.
Total acidity of curd is mandatorily required to be a minimum of 0.6% as per FSS Regulations.
As per Indian Standard, which is voluntary, the same shall be in the range of 0.6% to 0.8%.

The cross-over percentage ranges between 0 - 50%.
Crossover percentage value of linked genes (see linkage) that are exchanged during the process of crossing over during the first prophase of meiosis. It can be calculated by the percentage of offspring that show recombination and is used to map the genes on a chromosome.
A recombination frequency of 50% is therefore the maximum recombination frequency that can be observed and is indicative of loci that are either on separate chromosomes or are located very far apart on the same chromosome.

Most successful example of cooperative in milk is Anand.
The world famous co-operative dairy 'Amul' is one of the main features of Anand. Amul is the biggest dairy not only in India but in Asia too.
It is owned by thousands of small and medium farmers. Amul has created a revolution.

During the programme of 'Operation Flood-I' four Mother Dairies were established at Bombay, Madras, Calcutta and New Delhi.
NDDB planned the program and negotiated the details of EEC assistance. During this phase Operation Flood linked 18 of India's premier milk sheds with consumers in India's major metropolitan cities: Delhi, Mumbai, Kolkata, and Chennai, establishing mother dairies in the four metros.

The milk vein in cows contains Blood.
Two milk veins carry blood from the udder to the heart together with two veins in the abdominal cavity. Two arteries carry blood to and from the udder.
When a cow is lying down, 20% more blood flows through the udder; therefore, cows must be able to lie down for sufficient periods.

The duration of oestrus in goats is 24 - 48 hours.
Average duration of estrus is 24 to 48 hours, with ovulation occurring toward the end of estrus or approximately 24 hours after the onset of estrus.
In goats, the length of the estrous cycle is an average of 21 days but can vary between 18 and 24 days.

TDN in crude fibre is < 60%.
The energy value of forage is expressed as total digestible nutrients. Typically, the greater the value, the more energy-dense the forage is considered. Low-quality hay is generally 45 to 52% TDN.
TDN is determined by multiplying the digestion coefficient for organic matter, D, by a conversion factor calculated by the formula: F = M (0.01 + 0.000125 E) where M is the percent organic matter in the dry matter of the feed and E is the ether extract as percent of the organic matter.

Operation Flood I' was launched in 1970.
Operation Flood, launched on 13^th January 1970, was the world's largest dairy development program and a landmark project of India's National Dairy Development Board (NDDB).
It transformed India from a milk-deficient nation into the world's largest milk producer, surpassing the United States of America in 1998 with about 22.29 percent of global output in 2018.
Operation Flood is the program that led to the "White Revolution." It created a national milk grid linking producers throughout India to consumers in over 700 towns and cities and reducing seasonal and regional price variations while ensuring that producers get a major share of the profit by eliminating the middlemen.
