Hand-rearing, artificial-rearing, human-rearing or hand-raising is the process of caring for and feeding juvenile animals by humans during a stage when they would normally be fed by their parents. [1]
For the hand-rearing of mammals, a bottle with milk from a female of their species, milk from another closely related species, or an appropriate milk formula can be used. [1] [2]
In the case of birds, in some instances, hand-rearing with puppets that mimic the mother's head with key features to stimulate the chick's beak opening and food ingestion may be necessary. [3]
Hand-rearing can lead to habituation or imprinting of these animals towards humans, with the risk that adults may not exhibit normal behavior towards their species' companions, especially in animals raised for reintroduction into the wild. Potential difficulties include integration into groups of conspecifics, learning natural behaviors such as hunting, choosing a mate, as well as raising their own offspring. [1] [4]
However, in livestock farming and domestic animal breeding, habituating animals to humans can be of great utility. [4] [5]
The Iberian lynx is one of the four extant species within Lynx, a genus of medium-sized wild cats. The Iberian lynx is endemic to the Iberian Peninsula in southwestern Europe. It is listed as vulnerable on the IUCN Red List. In the 20th century, the Iberian lynx population had declined because of overhunting, poaching, fragmentation of suitable habitats, and the population decline of its main prey species, the European rabbit, caused by myxomatosis and rabbit haemorrhagic disease. Fossils suggest the species has been present in Iberia since the end of the Early Pleistocene, around one million years ago.
The Iberian language was the language of an indigenous western European people identified by Greek and Roman sources who lived in the eastern and southeastern regions of the Iberian Peninsula in the pre-Migration Era.

Cross-fostering is a technique used in animal husbandry, animal science, genetic and nature versus nurture studies, and conservation, whereby offspring are removed from their biological parents at birth and raised by surrogates, typically of a different species, hence 'cross.' This can also occasionally occur in nature.
The Iberian wolf, is a subspecies of grey wolf. It inhabits the northwest of the Iberian Peninsula, which includes northwestern Spain and northern Portugal. It is home to 2,200-2,700 wolves which have been isolated from mixing with other wolf populations for over a century. They form the largest wolf population in Western Europe.

The Lince was a Spanish development programme for a proposed main battle tank that unfolded during the late 1980s and early 1990s. The intention was to replace the M47 and M48 Patton tanks that the Spanish Army had received under the U.S. Mutual Defense Assistance Act between 1954 and 1975, and to complement the AMX-30E tanks manufactured for the army during the 1970s. Companies from several nations, such as German Krauss-Maffei, Spanish Santa Bárbara, and French GIAT, made bids for the development contract. The main priorities were mobility and firepower, with secondary priority placed on protection; the Lince tank was to have been lighter and faster than its competitors. To achieve a sufficient level of firepower and protection, the Lince was to use Rheinmetall's 120 mm L/44 tank-gun and German composite armour from the Leopard 2A4.
The Verata is a traditional Spanish breed of domestic goat. It is a dual-purpose breed, reared both for its meat and for its milk.

It is one of two traditional goat breeds in Extremadura, the other being the Retinta Extremeña.

The 2007 vole plague began in early summer 2006 in the province of Palencia, in the Spanish autonomous community of Castile and León. In the summer of 2007, crops in the plateau fields were devastated by rodents. In September 2007, after a summer of severe losses, the density of rodents decreased throughout the community and the plague was institutionally considered to be over. However, there was an abundance of voles during the following months. Only the winter frosts and the low temperatures of November and December reduced vole numbers to normal.
Fostering, in falconry and reintroduction of birds, is a method of breeding birds for their introduction into the wild that consists of placing chicks in the nest of a couple that has others of a similar age and size. Sometimes it can also be used when the chicks have already left the nest but continue to be fed by their parents.
Puppet-rearing is a method of breeding birds in captivity for their reintroduction into the wild that consists of feeding chicks with puppets that simulate adults of their species to avoid direct contact with humans.
Human-guided migration or human-led migration is a method of restoring migratory routes of birds bred by humans for their reintroduction into the wild.
