Hanh, H. Q., Phuong, N. T., Tien, N. D. et al. 2023. Effects of stocking density in group cages on egg production, profitability, and aggressive pecking of hens. Journal of Applied Animal Welfare Science 26(3), 374–385.

There is an increasing concern about welfare issues related to battery cages, which are commonly used in Vietnam, and requires a modified cage that improves hen welfare while retaining its economic and management advantages. We...

Hall, C. A., Potvin, D. A., Conroy, G. C. 2023. A new candling procedure for thick and opaque eggs and its application to avian conservation management. Zoo Biology 42(2), 296–307.

The ability to monitor developing avian embryos and their associated vascular system via candling enables the application of important reproductive management techniques. Egg candling facilitates the confirmation of egg viability throughout the incubation process and...

Elane, G. L., Portela, D. A., Hobbs, K. J. et al. 2023. Sedated cesarean sections are associated with increased kid survival compared to general anesthesia in goats:

OBJECTIVE To determine whether anesthesia type (sedation or general anesthesia) affects kid survival to discharge in caprine cesarean sections (C-sections). ANIMALS Retrospective cohort of 99 caprine C-sections (2011–2021). PROCEDURES All surgeries were performed via left...

Powell, J., Collins, T., Beaty, T. et al. 2023. A fat tailed what?!: Navigating husbandry for the fat tailed dunnart (Sminthopsis crassicaudata). Laboratory Animal Science Professional 11(4) (July/August), 46-48.

FTDs are Australian carnivorous nocturnal marsupials, whose diet, environmental needs, and enrichment vary from typical research species. Due to the limited working knowledge on the husbandry and care of this species in a biomedical setting...

Piekarski, N., Hobbs, T. R., Jacob, D. et al. 2023. A comparison of oocyte yield between ultrasound-guided and laparoscopic oocyte retrieval in rhesus macaques. Animals 13(19), 3017.

Obtaining quality oocytes is a prerequisite for ART-based studies. Here we describe a method for transabdominal ultrasound-guided (US) oocyte retrieval in rhesus macaques (Macaca mullata) and compare it to the standard surgical approach using laparoscopy...

Crawford, C., Rand, J., Rohlf, V. et al. 2023. Solutions-based approach to urban cat management—Case studies of a One Welfare approach to urban cat management. Animals 13(21), 3423.

Urban free-roaming cats create concern about their impacts on wildlife and human health, leading to the use of trap–adopt–kill methods to manage these populations. This method is ineffective at decreasing the free-roaming cat population and...

Bilkó, Á., Petróczi, I., Bárdos, B. et al. 2022. Composition of the wild rabbit nest and its implication for domestic rabbit breeding. Applied Sciences 12(4), 1915.

Wild European rabbits (Oryctolagus cuniculus) give birth in an underground nursery burrow where the kits are hermetically closed into the nest chamber for several weeks except for the three minutes of daily nursing. Given this...

Abayarathna, T., Webb, J. K. 2020. Effects of incubation temperatures on learning abilities of hatchling velvet geckos. Animal Cognition 23(4), 613–620.

Stressful environments in utero can have a profound influence on cognitive functions and learning ability. In lizards, thermal environments experienced by embryos can shape a range of traits, including sex, body size, and locomotor performance...

Núñez-Murrieta, M. A., Coria-Avila, G. A., Martínez, A. J. et al. 2023. Preterm rat survival is enhanced by gestational environmental enrichment. Behavioural Processes 205, 104820.

Throughout the last decade, the estimated global human preterm birth rate was 10.6 %, with higher rates in Asia, South America, and Africa. Preterm individuals, even in adulthood, are more likely to develop cardiorespiratory, renal...

Kondrashev, S. L. 2023. Trichromatic vision in toads: Evidence from preference for colour objects during mate choice. Behaviour 160(8), 753–784.

Input of different spectral types of photoreceptors in amphibian colour vision has been assessed by studying the behaviour of male toads Bufo bufo and B. gargarizans in a laboratory. This method is based on the...
