[#376] Distal intestinal obstruction in bullock is diagnosed by
Correct Answer
(C) Per rectal examination
Explanation
Solution: Distal intestinal obstruction in bullock is diagnosed by per rectal examination. Distal intestinal obstruction syndrome (DIOS) involves obstruction of the distal part of the small intestines by thickened intestinal content and occurs in about 20% of mainly adult individuals with cystic fibrosis. A complete history and physical examination can be suggestive, especially if a palpable mass in the right lower quadrant of the abdomen is present. Ultrasound and computed tomography (CT) imaging of the abdomen can confirm the diagnosis by demonstrating dilated loops of intestine with material in the intestinal lumen with bubbles.
[#377] Rickets is due to deficiency of
Correct Answer
(B) Vitamin D
Explanation
Solution: Rickets is due to deficiency of Vitamin D. Rickets is a condition that results in weak or soft bones in children and is caused by either dietary deficiency or genetic causes. Symptoms include bowed legs, stunted growth, bone pain, large forehead and trouble sleeping. The most common cause of rickets is a vitamin D deficiency. This can result from eating a diet without enough vitamin D, dark skin, too little sun exposure, exclusive breastfeeding without vitamin D supplementation, celiac disease, and certain genetic conditions.
[#378] Mule is the cross of
Correct Answer
(A) Mare × Ass
Explanation
Solution: Mule is the cross of Mare × Ass. The mule is a domestic equine hybrid between a donkey and a horse. It is the offspring of a male Ass (a jack) and a female horse (a mare). A female mule that has oestrus cycles, and so could, in theory, carry a foetus, is called a "molly" or "Molly mule", although the term is sometimes used to refer to female mules in general. A male mule is properly called a "horse mule".
[#379] Which of the following is common in nature?
Correct Answer
(C) D sugars and L amino acids
Explanation
Solution: D sugars and L amino acids are common in nature. D- and L- is a way of describing the absolute configuration of molecules that pre-date the (R, S) CIP system. D- and L-is an old but still-convenient shorthand for saying that molecules are enantiomers. These compounds are called R and S enantiomers (or isomers). However, when amino acids or sugars are chiral, scientists call them D and L isomers. D- means “right-handed” and L- means “left-handed.”
[#380] Average period of lactation in buffalo
Correct Answer
(B) 281 days
Explanation
Solution: Average period of lactation in buffalo is 281 days. The lactation length is about 280 - 300 days in the Murrah breed and about 320 days in the Nili-Ravi breed. Milk yields range from 1500 to 1800 kg for the first lactation with a steady increase to a peak in the fourth lactation, and are then maintained at peak levels until the ninth lactation.
