Dietary inclusion of a Saccharomyces cerevisiae metabolite improved reproductive performance but did not affect intestinal permeability in two chicken meat breeder lines

Autor: Rebecca EA Forder, Nicky-Lee Willson, Joshua A Angove, Todd J McWhorter, Matthew A McQueen, David J Cadogan

Publikováno v: Poultry Science, Vol 103, Iss 5, Pp 103595- (2024)

ABSTRACT: Gastrointestinal dysbiosis is a disturbance in mucosal homeostasis, producing low-grade chronic intestinal inflammation and impaired intestinal barrier function. It is induced by several factors, including nutrition and stress, which are bo

Who reviews what you do at the zoo? Considerations for research ethics with captive exotic animals

Autor: Eduardo J Fernandez, Todd J McWhorter

Publikováno v: Research Ethics Review, Vol 19 (2023)

Research in zoos is an important scientific endeavor that requires several complex considerations in order to occur. Among those many considerations are the ethics involved in conducting zoo research. However, it is not always clear how zoo researche

Paracellular absorption is relatively low in the herbivorous Egyptian spiny-tailed lizard, Uromastyx aegyptia.

Autor: Todd J McWhorter, Berry Pinshow, William H Karasov, Christopher R Tracy

Publikováno v: PLoS ONE, Vol 8, Iss 4, p e61869 (2013)

Absorption of small water-soluble nutrients in vertebrate intestines occurs both by specific, mediated transport and by non-specific, passive, paracellular transport. Although it is apparent that paracellular absorption represents a significant route

Is Continuous Monitoring of Skin Surface Temperature a Reliable Proxy to Assess the Thermoregulatory Response in Endurance Horses During Field Exercise?

Autor: Elisabeth-Lidwien J. M. M. Verdegaal, Gordon S. Howarth, Todd J. McWhorter, Catherine J. G. Delesalle

Publikováno v: Frontiers in Veterinary Science, Vol 9 (2022)

Hyperthermia is a performance and welfare issue for exercising horses. The thermoregulatory stressors associated with exercise have typically been estimated by responses in the laboratory. However, monitoring surface skin temperature (Tsk) coincident

Continuous Monitoring of the Thermoregulatory Response in Endurance Horses and Trotter Horses During Field Exercise: Baselining for Future Hot Weather Studies

Autor: Elisabeth-Lidwien J. M. M. Verdegaal, Gordon S. Howarth, Todd J. McWhorter, Berit Boshuizen, Samantha H. Franklin, Carmen Vidal Moreno de Vega, Stacey E. Jonas, Louise E. Folwell, Catherine J. G. Delesalle

Publikováno v: Frontiers in Physiology, Vol 12 (2021)

Establishing proper policies regarding the recognition and prevention of equine heat stress becomes increasingly important, especially in the face of global warming. To assist this, a detailed view of the variability of equine thermoregulation during

Sucrose digestion capacity in birds shows convergent coevolution with nectar composition across continents

Autor: Todd J. McWhorter, Jonathan A. Rader, Jorge E. Schondube, Susan W. Nicolson, Berry Pinshow, Patricia A. Fleming, Yocelyn T. Gutiérrez-Guerrero, Carlos Martínez del Rio

Publikováno v: iScience, Vol 24, Iss 7, Pp 102717- (2021)

Summary: The major lineages of nectar-feeding birds (hummingbirds, sunbirds, honeyeaters, flowerpiercers, and lorikeets) are considered examples of convergent evolution. We compared sucrose digestion capacity and sucrase enzymatic activity per unit i
