Definition
In property law, "young animals" refers to offspring of animals, particularly as the subject of a rule of ownership: the offspring of domestic or tame animals belongs to the owner of the dam (the mother). This principle resolves disputes about who owns newborn livestock, pets, or other domesticated creatures when ownership of the mother and father may be divided between different persons, or when the mother was borrowed, leased, or otherwise temporarily in another's possession.
The rule applies to domesticated animals generally and is grounded in the legal maxim partus sequitur ventrem — "the offspring follows the womb." Ownership of the young tracks ownership of the mother, not the father.

Common Language
Modern common usage (Wiktionary): Young animals are simply the juvenile or newborn offspring of any animal species — a descriptive biological term with no legal charge.
Historical common usage (Webster's 1913): Similarly descriptive; denotes animals in an early stage of life or development.
Editorial note: The gap between common and legal usage is one of specificity and consequence. In ordinary speech, "young animals" is purely descriptive. In law, the phrase carries a precise ownership rule that determines who holds property rights in newborn livestock and other domestic creatures — a determination that could have substantial economic stakes in agricultural and commercial contexts.

Why It Matters in Research
Researchers working with historical property law sources — particularly those touching on agricultural economies, livestock disputes, or tenancy arrangements — will encounter this principle embedded in broader treatments of animal ownership rather than under a standalone heading. Bouvier's entry is brief and points outward to Roman law sources; researchers should not expect the common law sources to have developed a rich independent doctrine under this label.
The most important trap in historical sources is conflation with the separate question of wild animal ownership, which follows entirely different rules (ferae naturae doctrine). The partus sequitur ventrem rule applies to domesticated animals; it does not resolve ownership of the offspring of wild animals captured or kept in captivity, which historically was governed by possession and control principles. Historical dictionaries do not always cleanly separate these tracks.
The maxim partus sequitur ventrem has a fraught American history: it was applied in antebellum slave law to determine that children born to enslaved mothers were themselves enslaved regardless of the father's status. Researchers encountering this maxim in American historical sources must be alert to that usage and context, which appears in a very different body of legal literature than livestock disputes but uses the same Latin formulation.
In modern research contexts, the ownership-of-offspring question most often arises in connection with strict liability for animal injuries — specifically, whether the owner of a dam is also the owner of offspring that cause harm. The encyclopedia entries on domestic and wild animal liability (torts_139, torts_140) are the natural next stop for researchers moving from ownership into liability questions.

Historical Dictionary Support
Bouvier's Law Dictionary states the rule plainly: offspring of domestic or tame animals belongs to the owner of the dam, citing the Digest (Dig. 6.1.5.2) and the Institutes (Inst. 2.1.9) of Justinian — confirming that this is a principle received directly from Roman civil law into the common law tradition. Bouvier offers no elaboration on exceptions, edge cases, or the distinction between wild and domestic animals, suggesting the entry was intended as a reference point rather than a comprehensive treatment.
The Roman law sources Bouvier cites treat the rule as part of the law of accession — the general principle that things produced by or attached to a thing belong to the owner of that thing. In that framework, the young of animals are treated analogously to the fruit of a tree or the product of soil: natural increase belongs to the owner of the productive asset.
What Bouvier and the historical dictionary tradition do not address: the treatment of offspring when the dam is held under a usufruct, lease, or bailment arrangement; disputes over offspring of wild animals held in captivity; and the modern complications introduced by artificial reproduction, embryo transfer, and genetic ownership questions in commercial breeding. Researchers dealing with those issues will need to move beyond the historical dictionary sources to treatises and case law.

Jurisdictional Note
The partus sequitur ventrem rule for domestic animal ownership is broadly consistent across common law jurisdictions, reflecting its Roman law origins and early reception into English common law. Modern variations arise primarily in commercial livestock and breeding contexts, where contractual arrangements routinely override the default rule. Some jurisdictions have specific statutory provisions governing livestock ownership and estray animals that interact with or displace the common law baseline.
