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.Links to papers and other sources mentioned in this podcast--------------------------------------------------------------- Carmickle et al. 2022, Physiological responses of Holstein calves and heifers carrying the SLICK1 allele to heat stress in California and Florida dairy farms.https://www.journalofdairyscience.org/article/S0022-0302(22)00527-6/fulltextDOI: 10.3168/jds.2022-22177Dikmen et al. 2014, The SLICK hair locus derived from Senepol cattle confers thermotolerance to intensively managed lactating Holstein cows.https://www.journalofdairyscience.org/article/S0022-0302(14)00457-3/fulltextDOI: 10.3168/jds.2014-8087Sosa et al. 2021, Inheritance of the SLICK1 allele of PRLR in cattle.https://onlinelibrary.wiley.com/doi/10.1111/age.13145DOI: 10.1111/age.13145Vapometer to measure the speed of water leaving the skinhttps://delfintech.com/products/vapometer/

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.PaperCast is also available as an audio podcast!Find us on: Apple Podcasts: https://podcasts.apple.com/us/podcast/dairy-focus-papercast/id1530748959Spotify: https://open.spotify.com/show/223Pv4qwRcMFyyy3CXdL3rPodcast Addict: https://podcastaddict.com/podcast/3098543Podchaser: https://www.podchaser.com/podcasts/dairy-focus-papercast-1420022RSS: https://feeds.buzzsprout.com/1327510.rssLinks to papers and other sources mentioned in this video --------------------------------------------------------------- Hristov et al. 2022.
