Which feature was introduced for the first time in India's 20th Livestock Census?
C. Digital data entry on tablet computers
The 20th census was the first recorded online on tablets, and it counted animals by breed. Poultry, household-based enumeration and separate buffalo counts were all part of earlier censuses.

Which cattle breed is characterised by a prominent convex forehead and long, pendulous, leaf-like ears?
A. Gir
The bulging forehead and long curled leaf-like ears are the hallmark of Gir from Saurashtra, Gujarat. Hariana and Ongole are white dual-purpose breeds with flat foreheads; Kangayam is a Tamil Nadu draught breed.

The Rashtriya Gokul Mission, started in 2014, is aimed mainly at:
D. Conservation and development of indigenous bovine breeds
The Rashtriya Gokul Mission supports the development and conservation of indigenous cattle and buffalo breeds. FMD control is under the National Animal Disease Control Programme.

Heifers are best bred when they reach approximately what proportion of mature body weight?
D. 55-65%
A common guide is to breed at about 55-65% of mature weight. Puberty occurs at about 40-45%, and about 80-85% is the target at first calving.

Using the Indian rule of thumb, a cow on good roughage yields 10 kg milk daily. With a maintenance allowance of 1.5 kg concentrate and 1 kg concentrate per 2.5 kg milk, how much concentrate should she get?
D. 5.5 kg
Concentrate = maintenance + milk/2.5 = 1.5 + 10/2.5 = 1.5 + 4.0 = 5.5 kg. 4.0 kg omits maintenance; 6.5 kg uses the buffalo ratio of 1 kg per 2 kg milk (10/2 = 5, plus 1.5); 25 kg multiplies instead of dividing.

Feeding extra concentrate to a pregnant cow during the last 6-8 weeks of gestation is called:
B. Steaming up
Steaming up supports late fetal growth, udder development and reserves for lactation. Flushing is extra energy around mating; challenge feeding raises concentrate in early lactation; creep feeding is for young stock.

Well-made maize silage is preserved mainly by:
C. Lactic acid from anaerobic fermentation, lowering the pH
Silage is packed airtight so lactic acid bacteria ferment sugars and lower the pH. Butyric acid indicates poor, clostridial fermentation; drying below 15% moisture describes hay.

Using the guide of about 10% of body weight as early colostrum, how much colostrum does a 40 kg calf need within its first several hours?
A. About 4 litres
10% of 40 kg = 4 kg, about 4 litres. 0.4 L is 1%; 10 L confuses 10% with 10 litres; 1 L is far too little for adequate passive transfer.

A dairy herd has a 365-day calving interval and a 60-day dry period. Approximately what percentage of cows will be in milk at any time?
B. About 84%
Lactation length = 365 - 60 = 305 days; cows in milk = 305 / 365 x 100 = 83.6%, about 84%. 16% is the dry fraction; 120% divides the interval by the lactation.

Which cost usually forms the largest share of the cost of milk production?
B. Feed and fodder
Feed commonly accounts for about 60-70% of the cost of milk production in Indian studies, which is why feeding efficiency drives profit.
