[#651] Life span of cattle
Correct Answer
(B) 20 - 25 years
Explanation
Solution: The life span of cattle is 20 - 25 years. Cattle are very gregarious and even short-term isolation is considered to cause severe psychological stress. The natural life expectancy of cattle could be as much as 20 - 25 years, after about five years, a cow's milk production has dropped
at which point most dairy cows are sent to slaughter.
[#652] Curd tension of dahi
Correct Answer
(C) Is lower than milk
Explanation
Solution: Curd tension of dahi is lower than milk. The rennet curd tension was determined at a temperature of 35° and with a rennet concentration of 0.018 percent
the technique was the same as that used in the Hill curd test except that only rennet extract was used as the coagulant and the time allowed for the formation of curd was 45 minutes instead of 10 minutes. The raw milk used had an average curd tension of 60 gm. The average curd tension in dahi prepared from buffalo milk was higher (43.44 g) than that prepared from cow milk (34.94 g).
[#653] The heat period of goat is
Correct Answer
(D) 18 - 24 h
Explanation
Solution: The heat period of goat is 18 - 24 h. The estrous cycle is the set of recurring physiological changes that are induced by reproductive hormones in most mammalian therian females. In species with estrous cycles, females are generally only sexually active during the estrus phase of their cycle. This is also referred to as being "in heat". The estrous cycle in goats is 21 days, on average. The estrus or heat phase lasts 12 - 48 hours
however, the average length is 36 hours.
[#654] Name the plant which commonly causes bloat.
Correct Answer
(A) Clover
Explanation
Solution: Clover plant commonly causes bloat. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 cm tall. The leaves are trifoliate with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers
the small, few-seeded pods are enclosed in the calyx. Clover is foraged by wildlife, including bears, game animals, and birds. Native Americans ate the plants raw and cooked, drying and smoking the roots. It causes bloating in cattle as well as humans.
[#655] Samples suspected for Pox virus are inoculated in embryonated eggs by the route of
Correct Answer
(C) CAM
Explanation
Solution: Samples suspected of Pox virus are inoculated in embryonated eggs by the route of CAM. Embryonated chicken eggs are inoculated by the allantoic route at approximately the middle of the 21 days embryonation period, at 8 - 10 days of embryonation
they are inoculated by the amniotic route late in the incubation period, at 14 - 16 days of embryonation.
