Siri is mostly found in Darjeeling.
Siri is a small-sized draught purpose breed of hilly region of West Bengal and Sikkim. The breed is also known as "Trahbum”.
The breeding tract of the breed includes Darjeeling district of West Bengal and Sikkim north, Gyalshing, Namchi, Gangtok, Sikkim east, Sikkim south and Sikkim west of Sikkim.

The pork producers prefer to produce pork of the type leaner and have less fat.
There are four major criteria used in measuring pork quality: colour, marbling, water-holding capacity, and ultimate pH.
Pork that is a pinkish-red colour will provide a better eating experience. Avoid choosing meat that is pale in colour and has liquid in the package. Look for pork that has marbling, or small flecks of fat. Marbling adds flavour.

Mating animals of different breeds are known as Crossbreeding.
Crossbreeding refers to the science of mating animals derived from different breeds or breed compositions. Although many beef producers choose to breed only purebreds, crossbreeding can result in significant advantages to beef producers.
A crossbred animal has several advantages over a purebred, especially in traits important to commercial cattlemen: increased fertility, longevity, feed efficiency and disease resistance due to the phenomenon of hybrid vigour (heterosis).

Oestrus cycle of cows is 18 - 24 days.
The estrous cycle of the cow starts after puberty and occurs approximately every 21 days (18 to 24 days) except for pregnancy, reproductive disease or hormonal disorder.
During estrous cycle, the reproductive tract is prepared for estrus or heat (the period of sexual receptivity) and ovulation (ovum release).

DCP in non-legume crops is 0.5 - 1%.

Specific gravity of milk fat is 0.93.
Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.
Specific gravity for liquids is nearly always measured concerning water at its densest, for gases, the reference is air at room temperature.
The specific gravity of some major milk constituents is: water: 1.00; fat: 0.93, protein: 1.346, lactose: 1.666, salts: 4.23 and SNF: 1.616.

Rate limiting enzyme in cholesterol biosynthesis is HMG-CoA reductase.
The biosynthetic pathway of cholesterol proceeds through several intermediates and involves different enzymes.
The rate-limiting step of cholesterol synthesis is the enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase that synthesizes mevalonate starting from HMG-CoA.

More water is found in the milk of humans.
Breast milk or mother's milk is milk produced by mammary glands located in the breast of a human female.
Breast milk is the primary source of nutrition for newborns, containing fat, protein, carbohydrates (lactose and human milk oligosaccharides) and variable minerals and vitamins.
The milk of mammals that nurse frequently (including human babies) is less rich, or more watery, than the milk of mammals whose young nurse less often. Human milk is noticeably thinner and sweeter than cow's milk.

Maximum sheep population in Australia.
Australia has the third-largest sheep population at 74.722 million which is around 6.3% of the global population. New Zealand has one of the highest sheep to human ratios in the world with 5.1 sheep to every person.

Strauss reaction is positive for Brucella abortus, Pseudomonas mallei and Actinobacillus ligneresii.
The Straus reaction is seen in male guinea pigs inoculated intra peritoneally with infective material containing either P. pseudomallei or P. mallei.
The reactions of swelling of the testes, inflammation of the tunica vaginalis and ulceration of the scrotal skin develop in 2 - 3 days.
