Correct Answer

(C) Calcium

Explanation

Solution: Milk fever is caused due to deficiency of Calcium. Milk fever, postparturient hypocalcemia, or parturient paresis is a disease, primarily in dairy cattle but also seen in beef cattle and non-bovine domesticated animals, characterized by reduced blood calcium levels (hypocalcemia). It occurs following parturition, at onset of lactation when demand for calcium for colostrum and milk production exceeds the body's ability to mobilize calcium.

[#212] Conversion of spermatid into spermatozoa is
Correct Answer

(B) Spermiogenesis

Explanation

Solution: Conversion of spermatid into spermatozoa is Spermiogenesis. Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. Spermatogenesis produces mature male gametes, commonly called sperm but more specifically known as spermatozoa, which can fertilize the counterpart female gamete, the oocyte, during conception to produce a single-celled individual known as a zygote.

[#213] Average fertile life of an egg
Correct Answer

(A) 12 - 24 hours

Explanation

The highest pregnancy rates have been reported when the egg and sperm join together within 4 to 6 hours of ovulation. The egg moves down the fallopian tube and stays there for 12 to 24 hours, where it can be fertilized. Sperm can live inside the female reproductive tract for as long as five days after sexual intercourse under the right conditions.

[#215] Green fodder to be ensiled should have DM between
Correct Answer

(B) 30 - 35%

Explanation

Solution: Green fodder to be ensiled should have DM between 30 - 35%. Dry matter (DM) is the total of all the solid components in a plant without water content. Dry Matter % in the sample other than water including protein, fiber, fat, minerals, etc. Green fodder yield t/ha is 18 to 20. Dry matter content (%) is 30 - 35%. Crude protein content (%) is 20.00.
