RAS question
Which of the following cattle breeds of Rajasthan is primarily known for its high milk yield and is mainly found in the Bikaner and Ganganagar districts?
Correct answer: (D) Rathi.
Rathi is the Rajasthan cattle breed known for good milk production in the Bikaner-Ganganagar belt.
Explanation
Rathi fits both clues in the question: dairy value and location. The NDDB breed page lists Rathi's native tract as the Bikaner, Ganganagar and Jaisalmer districts of Rajasthan, and gives its milk yield as an average of 1560 kg, with a range of 1062-2810 kg. That directly supports the Bikaner-Ganganagar clue and explains why the breed is treated as a dairy answer in Rajasthan geography. ICAR material describes Rathi cows as efficient milk producers and places their breeding tract in Bikaner, Ganganagar, Hanumangarh and Jaisalmer. Tharparkar is a useful dual-purpose breed, but its Rajasthan tract is mainly Barmer, Jaisalmer and Jodhpur, so it does not match the district clue as well as Rathi.
Why the other options are wrong
- (A) Tharparkar is a useful dual-purpose breed, but its Rajasthan tract is mainly Barmer, Jaisalmer and Jodhpur, not the Bikaner-Ganganagar belt asked here.
- (B) Nagauri is primarily a draught breed valued for working ability and associated with Nagaur district, so it does not answer a high-milk-yield dairy clue for Bikaner and Ganganagar.
- (C) Kankrej is described as a dual-purpose breed mainly found in Barmer and Jalore, with drought resistance as a key strength rather than peak milk yield in the Bikaner-Ganganagar tract.
Concept
This tests Rajasthan's livestock geography: matching indigenous breeds with their functional use and breeding tract. RAS repeats this theme because animal husbandry is a standard part of Rajasthan economy and regional geography.
