The massive improvement in food production, as a result of effective genetic selection
combined with advancements in farming practices, has been one of the greatest …

Lactose is the main carbohydrate in mammals' milk, and it is responsible for the osmotic
equilibrium between blood and alveolar lumen in the mammary gland. It is the major bovine …

Genomic breeding programs have been paramount in improving the rates of genetic
progress of productive efficiency traits in livestock. Such improvement has been …

Selective breeding has been practiced since domestication, but early breeders commonly
selected on appearance (eg, coat color) rather than performance traits (eg, milk yield). A …

In its simplest form, longevity is defined as the ability to live a long life. Within the dairy
industry, longevity has been defined and measured in many different ways, and the aim of …

The current global energy scarcity is leading to a sharp increase in its price and indirectly in
the price of feed. Therefore, the large part of animal production that relies on cereals, pulses …

As the environments in which livestock are reared become more variable, animal robustness
becomes an increasingly valuable attribute. Consequently, there is increasing focus on …

Sufficient genetic variation in livestock populations is necessary both for adaptation to future
changes in climate and consumer demand, and for continual genetic improvement of …

A new breeding value that combines the amount of feed saved through improved metabolic
efficiency with predicted maintenance requirements is described. The breeding value …

African livestock breeds are numerous and diverse, and typically well adapted to the harsh
environment conditions under which they perform. They have been used over centuries to …
