TLDR
Data support the concept that greater responsiveness and sensitivity to PRL during transition to lactation may be associated with an increase in subsequent milk yield.About:

Metabolic and hormonal acclimation to heat stress in domesticated ruminants.
Umberto Bernabucci,Nicola Lacetera,Lance H. Baumgard,Robert P. Rhoads,Bruno Ronchi,Alessandro Nardone +5 more
TL;DR: A better understanding of the adaptations enlisted by ruminants during heat stress is necessary to enhance the likelihood of developing strategies to simultaneously improve heat tolerance and increase productivity.
Journal ArticleDOI
Invited review: genes involved in the bovine heat stress response.
TL;DR: The variation in EVHL among animals and the central role that HSF1 has in coordinating thermal tolerance suggest that there is opportunity to improve thermal tolerance via gene manipulation, which will lead to opportunities for improved animal performance via altered nutritional management.

Gene Networks Driving Bovine Mammary Protein Synthesis during the Lactation cycle
Massimo Bionaz,Juan J. Loor +1 more
TL;DR: The overall data support a central role of AA and glucose transporters and insulin signaling through mTOR for the regulation of protein synthesis in bovine mammary gland.
Journal ArticleDOI
Invited review: Heat stress effects during late gestation on dry cows and their calves
Sha Tao,Geoffrey E. Dahl +1 more
TL;DR: Benefits of heat stress during late gestation on dairy cattle are introduced, and the biological mechanisms that underlie the observed production and health responses in the dam and her fetus are discussed.

Apparatus, methods and processes for sorting particles and for providing sex-sorted animal sperm
Gary Durack,Jeffrey D. Wallace,Gary P. Vandre,Lon A. Westfall,Jeremy T. Hatcher,Niraj V. Nayak +5 more
TL;DR: In this article, a multi-channel system for classifying particles in a mixture of particles according to one or more characteristics including a common source of electromagnetic radiation for producing a beam of radiation and a beam splitter for producing multiple beams of radiation for each interrogation location associated with each flow channel of the system.

Journal ArticleDOI
Photoperiodic effects on dairy cattle: a review.
TL;DR: IGF-I has emerged as a possible mediator of the increase of milk yield in response to long-day photoperiod and can be combined effectively with other management techniques such as bST.
Journal ArticleDOI
Prolactin Regulation of Milk Secretion and Biochemical Differentiation of Mammary Epithelial Cells in Periparturient Cows
TL;DR: Periparturient infusion of PRL in cows treated with CB154 (CB154 plus PRL) prevented reductions in milk production and reduced the normal surges in serum PRL concentrations at parturition and during milking.
Journal ArticleDOI
An Improved Method for the Routine Biopsy of Bovine Mammary Tissue
TL;DR: Eight primiparous cows in midlactation were used to determine a method for the mammary biopsy of standing cows in full lactation, and the method was reliable and efficient.
Journal ArticleDOI
Lactogenic hormones: binding sites, mammary growth, secretory cell differentiation, and milk biosynthesis in ruminants.
TL;DR: Greater understanding of hormonal regulation of the ruminant mammary gland likely will result in development of techniques to produce milk more efficiently and perhaps capability to evaluate production potential of young animals.
Journal ArticleDOI
Prolactin receptor gene expression in rat mammary gland and liver during pregnancy and lactation
TL;DR: There were no significant differences in the relative proportions of long to short forms of PRL receptor mRNAs at the different reproductive states, but the proportion of the long form was slightly greater in mammary gland than in liver.
