Impact of a natural rubber-based scratcher as an environmental enrichment on the scratching behavior, cortisol level, and semen quality of stable male goats.

Background And Aim: Goats are valuable livestock because they can generate meat and milk for human consumption. Goat husbandry is becoming more intensive due to the growing demand for goat products, which may impact animal welfare and natural behavior. This study aimed to investigate the impact of natural rubber (para rubber)-based scratchers as an environmental enrichment on scratching behavior, cortisol levels, and semen quality in stable bucks (male goats/goats).

Ultrastructural characteristics of black marsh turtle spermatozoa obtained by electroejaculation.

The black marsh turtle (Geoemydidae: Siebenrockiella crassicollis) is a freshwater turtle that occurs in equatorial tropical climates in South East Asia. The semen of S. crassicollis was investigated by electroejaculation.
