Squid have nociceptors that display long-term sensitisation and spontaneous activity after bodily injury

Bodily injury in mammals often produces persistent pain that is driven at least in part by long-lasting sensitization and spontaneous activity (SA) in peripheral branches of primary nociceptors near sites of injury. While nociceptors have been described in lower vertebrates and invertebrates, outside of mammals there is limited evidence for peripheral sensitization of primary afferent neurons, . . . → Read More: Squid have nociceptors that display long-term sensitisation and spontaneous activity after bodily injury

Community digs deep for injured staffy

Staff at Nepean Animal Hospital have been fielding dozens of inquiries since an injured Staffordshire Bull Terrier named Earl was admitted to one of its hospitals on July 1.

Two local teenagers, Christina Jurjevic and Tobi Hamill, were driving on Llandilo Road, near Penrith, west of Sydney, when they saw a four-year-old Staffordshire cross that had apparently been struck by a vehicle. The dog sustained severe fractures, including a shattered pelvis and internal injuries.

Jurjevic and Hamill contacted Nepean veterinarian Tony Karolis, who agreed to meet the young women at the hospital and offered to halve the cost of treatment. Continue reading Community digs deep for injured staffy

Essay: Decreasing stress, aggression and injury in pigs housed in intensive production systems

Introduction
Animal welfare issues are inherent in any intensive production system that restricts animals to an environment incompatible with their behavioural needs (D’Eath & Turner, 2009). For example, intensive husbandry practices, such as a mix of pigs in a confined space, can result in significant stress reactions and displays of aggressive behaviour through frustration or restriction of natural behaviour (Guy et al., 2009; Yonezawa et al., 2009). This paper will discuss the use of pig-appeasing pheromone (PAP) to reduce aggression and social stress generally, and the importance of tail posture in predicting incidents of tail-biting injury in post-weaning piglets.
