Dairy Focus PaperCast Dr. Phil Cardoso

The SLICK haplotype, originally identified in Senepol cattle, has been introduced into Holsteins. Inheritance of the SLICK1 allele of the prolactin receptor gene improves thermotolerance of lactating Holstein cows under humid heat stress conditions.

Dr. Anna Denicol of the University of California-Davis, along with her research group, recently published a study on whether pre- and postweaning Holstein heifers carrying the SLICK1 allele would show physiological responses indicative of higher tolerance to heat stress in high- and low-humidity climates. In this video, Dr. Phil Cardoso talks with Dr. Denicol about her work.

Methane is a potent greenhouse gas that traps energy far more efficiently than carbon dioxide. Reduction of methane emissions is thus essential to slowing climate change, and livestock are a major source of these emissions. Dr. Phil Cardoso talks with Dr. Alex Hristov of Penn State University about nutritional strategies for mitigating production of methane by dairy cattle. They discuss the effectiveness of several different feed additives at reducing methane emissions and their effects on DMI and milk production.
