How to formulate a low-protein animal diet

An easy process to understand how feed-grade amino acids and crude protein specifications interact to form a balanced low-protein diet
There has been much talk about the need to formulate animal diets without antibiotics at low crude protein levels. The benefits are many, and the cost is nil or even positive when animal performance is factored in.

Understanding oligosaccharides in young animal nutrition

Oligosaccharides, one of the lesser-known feed additives — along with other functional fibers — have a tremendous role to play in the future of antibiotic-free diets for all animals.
Oligosaccharides are considered as one of the most valuable sources of prebiotic fibers in diets for young non-ruminant animals such as broilers, pullets, piglets and calves.

Is fishmeal production sustainable for the future?

An extremely valuable ingredient that has become the exclusive privilege of aquafeeds is now considered too expensive to be used in most farm animal diets.
Regular fishmeal (ranging from 60 to 70 percent crude protein) is produced by harvesting whole fish for the sole purpose of producing this protein-rich ingredient for feeding commercially raised animals.

Future of enzyme research in animal nutrition

Freedom to dream is what makes great scientists, but freedom is expensive!
A prominent enzyme researcher mentioned that if we want something better than an improved xylanase — when it comes to fiber enzymes — we must keep dreaming. Taking this piece of advice to heart, I decided to dream.

Piglets need water as much as they need feed

Providing water to suckling and weaned piglets does not stop at having one water outlet per pen as these animals undergo significant digestive development during this period.
Sow’s milk contains about 80 percent water, and therefore it is often assumed that suckling piglets cover their daily water requirements without supplemental water.
