Response of Holstein calves and heifers carrying the SLICK1 allele to heat stress
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 to...

Effective nutritional strategies to mitigate enteric methane in dairy cattle
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 DM...

Sodium butyrate and monensin supplementation to postweaning heifer diets
Dr. Phil Cardoso talks with Dr. Peter Erickson and Tess Stahl of the University of New Hampshire about the effects of feeding diets containing supplementary sodium butyrate and monensin on growth performance, nutrient digestibility, and health in postweaned heifers.Links to papers mentioned in this video Stahl TC, Hatungimana E, Klanderman KD, Moreland SC, Erickson PS. 2020.

How prepartum stocking density and blinds affect calving in Holstein cows
Dr. Phil Cardoso talks with Dr. Kate Creutzinger of the University of Guelph and Dr. Katy Proudfoot of the University of Prince Edward Island about the effects of prepartum stocking density and a blind on physiological biomarkers, health, and hygiene of transition Holstein dairy cows.Links to papers mentioned in this video Creutzinger et al. 2020, Effects of prepartum stocking density and a blind on physiological biomarkers, health, and hygiene of transition Holstein dairy cows.DOI: 10.3168/j...

Palmitic to oleic acid ratio and its effect on milk production
Dr. Phil Cardoso and Dr. Adam Lock of Michigan State University discuss Dr. Lock’s recent study on the effect of supplementing two major fatty acids, palmitic and oleic acid, in different ratios on milk production in high-, medium- and low-producing cows.Links to papers mentioned in this episode Western et al. 2020, Milk production responses to altering the dietary ratio of palmitic and oleic acids varies with production level in dairy cows.DOI: https://doi.org/10.3168/jds.2020-18936https://p...

Comparison of diet strategies for multiparous and primiparous cows
Dr. Phil Cardoso and Dr. Jim Drackley of the University of Illinois and Dr. Bruce Richards of Delaware Valley University discuss their recent paper comparing prepartum low-energy or high-energy diets with a 2-diet far-off and close-up strategy for multiparous and primiparous cows.Links to papers mentioned in this videoRichards et al. 2020, Comparison of prepartum low-energy or high-energy diets with a 2-diet far-off and close-up strategy for multiparous and primiparous cows.DOI: 10.3168/jds.2...
