In a continuing effort to better understand the transmission and persistence of chronic wasting disease in wild populations of cervids, Colorado State University, Fort Collins houses two species of deer indoors to study the pathogenesis of chronic wasting disease. Here we report key aspects regarding the husbandry and medication of Reeves' muntjac and white-tailed deer in captivity for research purposes.

As one of the most sensitive and fragile alpine ecosystems in the Qilian Mountains, the alpine meadow holds significant scientific importance in understanding the changes in the characteristics of soil bacterial community in response to altitude and aspect variations. In our study, we analyzed the composition, diversity, and function of soil bacterial communities in alpine meadows at different altitudes and aspects and their relationship with environmental factors. Our results indicate that altitude and aspect orientation significantly influences the diversity index and composition of soil bacterial communities.

The gut microbiota plays an important role in the digestion, absorption, and metabolism of nutrients, as well as in the immunity, health, and behavior of donkeys. While reference genomes and gut microbial gene catalogs have been helpful in understanding the composition of the donkey, there is still a significant gap in sequencing and understanding the functional aspects of donkey gut microbial genomes. In this study, we analyzed metagenomic sequencing data from 26 donkeys' gut samples and successfully assembled 844 microbial metagenome-assembled genomes (MAGs).

Ensuring animal welfare is a key aspect of animal management in zoological facilities and aquaria, representing a pivotal facet of their mission. Italy currently lacks a comprehensive and valuable assessment methodology for evaluating the welfare of captive animals. To address this gap, the present study aimed to identify the most important criteria that should be considered in the welfare management and assessment of animals housed in Italian zoos and aquaria.

Cryopreservation induces various cryodamages to the structural or functional aspects of boar sperm, resulting in the deterioration of sperm quality. The extent of cryodamages varies significantly among different individual boars. In our study, 50 boars with either good sperm freezability (GSF) or poor sperm freezability (PSF) were selected from a population of 402 boars.

Litter size in pigs is affected by factors such as ovulation number, embryonic survival, and uterine environment conditions. Endometrial epithelial and stromal cells represent the first site of contact between the embryo and sows; therefore, dynamic changes in the growth and development of these cells are among the major factors affecting the intrauterine environment and implantation. Bone morphogenetic protein receptor type-1B (BMPR1B) is a receptor of the bone morphogenetic protein (BMP) family that has been identified as a candidate gene for reproductive traits in pigs.
