Animal Husbandry MCQ Question and Answer | Agriculture MCQ Question

Microbe in rumen capable of breaking lignocellulosic bonds is Fungi.
Rumen microbes include the protozoa, bacteria and fungi that live inside the rumen, one of the cow's four stomach compartments.
The capability of fungi to degrade lignocellulose containing raw materials is due to their highly effective enzymatic system.

Body temperature of hen 107°F.
The internal body temperature of birds shows more variability than mammals, and therefore there is no absolute body temperature. In the adult chicken the variability is between 105°F and 107°F.

Protease activity in rumen is highest for Protozoa.
Proteolytic enzymes (proteases) are enzymes that break down protein. These enzymes are made by animals, plants, fungi, and bacteria. This might help with digestion or with the breakdown of proteins involved in swelling and pain.
The proteolytic activity of the bovine rumen microflora was studied with azocasein as the substrate. Approximately 25% of the proteolytic activity of rumen contents was recovered in the strained rumen fluid fraction, and the balance of the activity was associated with the particulate fraction. The protozoal autolysates had high aminopeptidase activity, low deaminase activity was observed on endogenous amino acids.

Ovarian cycle in cows and buffalo is 21 days.
The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone.
The ovarian cycle of the cow is generally about 21 days long, but it can range from 17 to 24 days in duration. Each cycle consists of a long luteal phase (days 1 - 17) where the cycle is under the influence of progesterone and a shorter follicular phase (days 18 - 21) where the cycle is under the influence of estrogen. The estrous cycle in cattle is complex and regulated by several hormones and organs.

The number of chromosomes found in the river buffalo is 2n = 50.
The genetic diversity among the two types of buffaloes (river and swamp) exists to the extent of different numbers of diploid chromosomes 2n = 50. The diploid chromosome number of the swamp buffalo from both countries was 48 and that of the river buffalo was 50, while all F1 hybrids exhibited 49 chromosomes.

Gestation period of cows is 283 - 285 days.
Gestation is the period of development during the carrying of an embryo, and later foetus, inside viviparous animals. It is typical for mammals but also occurs for some non-mammals. The time interval of gestation is called the gestation period.
281 days are the average gestation period for cows with about equal chances for calving on any day from the 275^th to the 287^th day after service.

Gestation period of sheep is 145 days.
Gestation is the period of development during the carrying of an embryo, and later foetus, inside viviparous animals. It is typical for mammals, but also occurs for some non-mammals. The time interval of a gestation is called the gestation period.
Average gestation length or length of pregnancy for sheep varies from 144 to 151 days (about 147 days) Individual pregnancies may vary from 138 to 159 days.

Animal Protozoa are unicellular and they are Eukaryotic.
Protozoa are a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris.
Protozoans were regarded as "one-celled animals", because they often possess animal-like behaviours, such as motility and predation, and lack a cell wall, as found in plants and many algae.

The NDRI is located at Karnal.
The National Dairy Research Institute (NDRI), Karnal is India's premier institute for dairy research. The institute was accorded the status of Deemed University in the year 1989.
It has contributed a lot to the growth of the dairy industry and played a crucial role in India's development of milk production with its continuous research. The institute provides high-quality education in the field of dairying.

Puberty in pigs comes at 6 - 8 months.
Sexual maturity is reached by both the male and female pig at about 6-8 months of age. At this time there is an inflection point on the weight curve. The female pig (sow) is ready to breed (reaches puberty) at 6 months of age and will show signs of being in heat.
The period from 6 - 8 months to about 18 months of age is called adolescence. After 18 months of age the weight curve is flattened.
