[#466] TDN in crude fibre is
Correct Answer

(A) < 60%

Explanation

Solution: 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.

[#468] Operation Flood I' was launched in
Correct Answer

(A) 1970

Explanation

Solution: 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.

[#469] Feed conversion ratio (kg feed/kg live wt. gain) in pig is
Correct Answer

(A) 3 kg

Explanation

Solution: 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.

[#470] Suitable pH for fish pond is
Correct Answer

(A) 6.5

Explanation

Solution: 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.
