DOI: 10.1007/s11250-025-04670-7
Abstract: The study examined the impacts of first-lactation milk yield and culling causes on lifetime performance traits in Holstein cows culled after their second to sixth parities. Complete lactations from 12,209 records belonging to 4522 culled… read more here.

DOI: 10.1080/00480169.2024.2418929
Abstract: ABSTRACT Aim To assess whether the fluoride concentration in the humeri of first-lactation, 2-year-old dairy cows with a spontaneous humeral fracture is significantly different from that of first-lactation, 2-year-old dairy cows without a humeral fracture.… read more here.

DOI: 10.1093/tas/txac035
Abstract: Abstract The northern Australia beef cattle industry operates in harsh environmental conditions which consistently suppress female fertility. To better understand the environmental effect on cattle raised extensively in northern Australia, new environmental descriptors were defined… read more here.

DOI: 10.1242/jeb.170902
Abstract: ABSTRACT Increased reproductive effort may lead to trade-offs with future performance and impact offspring, thereby influencing optimal current effort level. We experimentally enlarged or reduced litter size in mice during their first lactation, and then… read more here.

In utero exposure to thermal stress has long-term effects on mammary gland microstructure and function in dairy cattle

DOI: 10.1371/journal.pone.0206046
Abstract: Earth’s rising temperature has substantial repercussions for food-producing animals by increasing morbidity and mortality, diminishing reproductive potential, and reducing productivity. In the dairy industry this equates to massive losses in milk yield, which occur when… read more here.

DOI: 10.1371/journal.pone.0297657
Abstract: Dairy farmers do not recoup the rearing costs incurred from birth to first calving until second lactation but varying proportions of first lactation cows are removed from the herd before second calving. Herein, we used… read more here.

DOI: 10.3168/jds.2025-26662
Abstract: Staphylococcal species are frequently isolated from dairy cows milk and are a very common cause of intramammary infections (IMI). First lactation cows may already have an IMI at calving, and these may be acquired during… read more here.
