Reticulum is the smallest compartment of the ruminant stomach.
The reticulum is a pouch-like structure in the forward area of the body, close to the heart. The tissues in the reticulum form a network similar to a honeycomb. A small tissue fold lies between the reticulum and rumen, but the two aren't separate compartments.

All reactions in TCA cycle are reversible except the formation of Succinyl Co-A.
The citric acid cycle (CAC) or the TCA cycle (tricarboxylic acid cycle)is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.
Succinyl Co-A is irreversible stage, it generates NADH, and regenerates the 4C chain.

Order of the efficiency of conversion of Tryptophan to Niacin is Chicken > Pig > Duck > Cat.

Corynebacteria can be characterized as Non-motile, non-sporing, aerobic, Gram positive bacilli.
Corynebacteria are club-shaped, gram-positive, non spore forming bacteria, found in chines characters-like arrangement of cells. These are non-motile, aerobic, pleomorphic rods with coccoid or club-shaped appearance that are catalase-positive and non-acid-fast.
Bacteria are small, pleomorphic, aerobic, non-spore forming bacilli. They are Gram-positive and slightly club shaped.

When three breeds are crossed rotationally it is Triple crossing.
Three or more breeds are involved in rotational crossing. When males of three or more breeds are used in crossing over their crossbred female progeny alternately then it is called rotational crossing. If three breeds are used then it is called Three-way Rotational Crossing.

Bile is a yellow-green fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine.
Bile salts are stored in the gallbladder and secreted once the contents of the stomach have reached the small intestines where most fats are broken down. The pancreas secretes enzymes and alkalis to neutralize stomach acid.

Temperature required for artificial vagina in cow is 41°C.
The artificial vagina method is most widely used today for the collection of bull semen. The bull is allowed to mount a teaser cow and ejaculates when the penis is directed into the artificial vagina. The artificial vagina consists of a firm cylindrical tube with a thin-walled rubber lining.
An artificial vagina (AV), as used for bulls, is prepared as usual and the final internal temperature is brought to 40 - 50°C.

Nurse cells for sperm are called Sertoli cells.
Sertoli cells are a type of sustentacular "nurse" cell found in human testes that contribute to the process of spermatogenesis (the production of sperm) as a structural component of the seminiferous tubules.
Sertoli cells also act as phagocytes, consuming the residual cytoplasm during spermatogenesis.
