Incubation efficiency and chick health are fundamentally linked to fertile egg quality, which is influenced by both grading methods and breeder age. This study evaluated the effects of manual versus automated grading and Cobb breeder age (28–42, 43–56, and 57–70 weeks) on hatchability, chick quality, and embryonic mort...

This study aimed to evaluate the effects of incubator microclimate, broiler breeder age, and fertile egg storage duration on egg water loss in a commercial hatchery within a tropical climate. Data were collected from the environments (air-conditioned egg room and incubator) in order to perform microclimatic assessments...

Multidimensional on-farm assessment can identify welfare constraints that are not evident from production records alone, but protocols developed for housed cattle require careful interpretation when applied to pasture-based herds. This cross-sectional, descriptive multi-case study characterized dairy-cow welfare prof...

This study evaluated and compared morphophysiological characteristics associated with thermoregulation in North Tinerfeña goats and Canária sheep, both dark-coated and maintained under similar environmental conditions on the island of Tenerife, Spain. A total of 23 adult Canária de Pelo ewes (clinically healthy, multip...
