Parturition and Neonatal Parameters of Three Species of Rhinoceros under Managed Care in the United States
Rhinoceros species range from near threatened to critically endangered due to habitat loss and poaching. A sustainable ex situ breeding population is critically important to maintain genetic diversity and help ensure the survival of the species; however, not all populations under human care are self-sustaining. While rhinoceros reproductive physiology and pathology have been well studied, […]
Birth of common shovelnose rays (Glaucostegus typus) under captive conditions
The common shovelnose ray (Glaucostegus typus) is a poorly studied species of the Rhinobatidae family that occurs throughout the Indo-West Pacific. Although common in aquariums throughout the United States, there are currently no records of captive birth events. In 2013, a female common shovelnose ray housed at the Downtown Aquarium in Houston, Texas, USA gave […]
Strategic use of straw increases nest building in loose housed farrowing sows
In spite of domestication, sows are still genetically programmed to perform nesting behaviour close to farrowing. In order to facilitate nest building, a method for a strategic use of large quantities of straw has been developed by Swedish piglet producing farmers. The objectives of the present study were to quantify the effect of strategic use […]
