[#86] Temperature for LTLT pasteurization
Correct Answer
(A) 61° - 63°C
Explanation
Solution: The temperature for LTLT pasteurization is 61° - 63°C. Pasteurization is a process of food preservation in which packaged and non-packaged foods are treated with mild heat, usually to less than 100°C (212°F), to eliminate pathogens and extend shelf life. The LTST (Low Temperature Long Time) method depends on a mechanism in which low heat and low pressure are utilized to pasteurize a fluid milk product. In this process, milk is dispersed in the form of droplets into a process chamber and heated for 0.02 s at or below pasteurization temperatures (61° - 63°C).
[#87] Casein form . . . . . . . . of total milk proteins.
Correct Answer
(D) 80 - 83%
Explanation
Solution: Casein forms 80 - 83% of total milk proteins. Casein is a family of related phosphoproteins (αS1, aS2, β, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and Cow milk have a higher casein content than other types of milk with human milk having a particularly low casein content.
[#88] The animal resistant to Atherosclerosis is
Correct Answer
(A) Cattle
Explanation
Solution: The animal resistant to Atherosclerosis is Cattle. Atherosclerosis is a pattern of the disease arteriosclerosis in which the wall of the artery develops abnormalities, called lesions. These lesions may lead to narrowing due to the buildup of atheromatous plaque. Atherosclerosis affects only herbivores except for cattle. Dogs, cats, tigers, and lions can be saturated with fat and cholesterol.
[#89] Rumen degradable protein content is highest for
Correct Answer
(C) Groundnut cake
Explanation
Solution: Rumen degradable protein content is highest for Groundnut cake. Groundnut cake is a by product obtained after the extraction of oil. The cake contains 45 - 60% protein, 22 - 30% carbohydrate, 3.8 - 7.5% crude fibre and 4 - 6% minerals. A higher ruminal degradability of protein has been reported for groundnut cake at 0.46 and 0.42.
[#90] Equine plague is also called as
Correct Answer
(D) African Horse sickness
Explanation
Solution: Equine plague is also called African Horse sickness. African horse sickness (AHS) is a highly infectious and deadly disease caused by African horse sickness virus. It commonly affects horses, mules and donkeys. This disease can be caused by any of the nine serotypes of this virus. AHS is not directly contagious, but is known to be spread by insect vectors.
