Abstract:
... Photoperiod regulates the occurrence of unwanted male post-smolt maturation during the production of large (>100 g) Atlantic salmon (Salmo salar) smolts. However, the optimal daylength for triggering smoltification, but not male puberty, has yet to be established. We used either continuous light (24:0 light/dark) or long days (18:6 and 21:3) after a six week “winter” zeitgeber (12:12) to induce sm ...

Abstract:
... The body condition score (BCS) is a popular method used to assess the body condition of dogs. However, owner-misperception of canine body condition has shown to persist even after being guided by a BCS chart. We compared the BCS assessments performed by the owners of 95 large-sized, purebred dogs without and with the guidance of a 5-point BCS chart. Initially, only 23 of 95 dog owners accurately a ...

Abstract:
... Shoulder lesions can develop in sows during lactation and vary in severity, potentially leading to euthanasia of the sow. There are questions about how these lesions affect the sow’s welfare. Here, sows that were loaded into farrowing pens were monitored prospectively to elucidate the risk for lesion development. To determine whether the presence of shoulder lesions affected behavior, 44 sows with ...

Abstract:
... The historical rise of intensive agricultural practices is hypothesized to be related to declines of grassland and aerial insectivorous birds. Drivers of declines may also influence the overall abundance and spatial distribution of insects within agricultural landscapes. Subsequently, the food provisioning rate of birds breeding within more agro‐intensive landscapes may be impacted. Lower provisio ...

Abstract:
... One major cause of low fertility of cows in the summer is progesterone deficiency. We found that insertion of a controlled intravaginal drug‐releasing (CIDR) device containing progesterone after artificial insemination (AI) increases pregnancy per AI (P/AI) in cows with uterine disease and low body condition score after calving. Here, we treated only these two subgroups, during the summer and autu ...

The hypothesis of this prospective, observational, and pilot study was that change in nasopharyngeal lumen would be over 50% in Beagle dogs without cardiopulmonary diseases. Thus, we assessed the nasophary ...
