1. Introduction Dairy cows have to afford several endocrine, metabolic, reproductive, and immunological challenges during the productive cycle. These challenges are particularly pronounced during the transition period (TP), when cows experience a reduction in dry matter intake (DMI), leading to negative energy balance (NEB), lipomobilization, and body mass loss. This metabolic stress occurs alongside drastic changes in hormone concentrations, decreased blood calcium levels, and...

Thank you, Israel and greetings (long time no se!), for such a comprehensive and forward-looking article. Your insights illuminate how much progress we’ve made in understanding cow cooling—and how many questions still remain. One important contribution I’d like to offer comes from our experience in the Azores, where dairy farming is deeply rooted in a pasture-based system that coexists with a humid subtropical climate. While our region doesn't experience the prolonged extreme heat...

A cow’s biology and genetics set the stage for her milk production potential. Thanks to genomics, the pace of genetic progress has accelerated in recent years, pushing that potential ever higher. But are we feeding cows to match it? Today’s dairy cows can achieve more with better nutrition, yet their ability to physically consume enough nutrients lags behind their rising requirements. ...

The effects of dietary rumen-protected choline on mammary DNA methylation patterns

Introduction Animal production faces serious challenges, having to feed a growing population while dealing with increased competition for land, climate change and having to take a more sustainable approach. Sustainable agriculture requires us to meet society’s present needs without compromising the ability for current, or future generations, to meet their needs. The effectiveness by which an animal is capable to transform feed biomass into animal products determines the amount...

Introduction Trace minerals exist in cells and tissues of the body in a variety of chemical combinations and characteristic concentrations, depending on the trace mineral consumed and the tissue in which the trace mineral is metabolized (McDowell, 1992; Underwood and Suttle, 1999). Concentrations of trace minerals must be maintained within narrow limits in a cell (McDowell, 1989, 1992; Underwood and Suttle, 1999). Trace mineral deficiencies, toxicities, and imbalances require the...

Introduction The dairy industry continues to provide a nutritious food source to our growing global population. Throughout history this industry has undergone significant evolutions contributing to a “more sustainable” product. But what does sustainability really mean, and in animal agriculture, why do we care? According to the U.S. National Environmental Policy Act (NEPA) of 1969 sustainability is to “create and maintain conditions, under which humans and nature...

Introduction The global agricultural sector, including associated land-use changes, was responsible for emitting 10.6 gigatons (Gt) of carbon dioxide equivalent (CO 2 e), contributing considerably to the overall 53 Gt CO 2 e of global greenhouse gas (GHG) emissions (FAO, 2023). In the United States, the agriculture sector contributed 0.59 Gt CO 2 e in 2022, representing 9.36% of the nation's GHG emissions. This marked a 7.7% increase from 1990 levels...

The discovery of choline dates back to 1850s when French pharmacist, Théodore Gobley discovered a group of phospholipids that he named lecithin. Seventy years later, during the discovery of insulin by Frederick Banting, his student Charles Best noticed that depancreatized dogs developed hepatic lipidosis. Subsequently in the early 1930s, Best showed that supplementing lecithin reversed and prevented hepatic lipidosis in dogs and rats. It took another 67 years for dietary choline to be...

It is not surprising to me that the success of dairy production in harsh environmental conditions in Israel. This review indicates that the Israeli cow became the “world champion” in milk production. The production of milk with economic efficiency and a relatively low emission of methane into the environment. It seems to me that not only the genetic factor of Israel cattle breed but other factors e,g, environmental management, nutrition, animal husbandry, physiiological and biochemical...

Choline supplementation is known to modify hepatic lipid metabolism in the dairy cow, but little is known about its effect on mammary lipid metabolism. The objective of this study was to characterize the effect of increasing doses of abomasally infused choline on milk production and milk lipids using untargeted lipomics. A total of 12 ruminally cannulated Holstein cows were used in a 4 × 4 Latin square design with 7-d experimental and 7-d rest periods. All cows were fed a common TMR...

Heat stress (HS) has detrimental effects during all stages of dairy cattle life. Cows that experience HS reduce dry matter intake, milk yield, and its composition. In addition, HS has major effects on a cow's health and fertility and negatively impacts a cow's welfare. The decrease in the efficiency of milk production in such conditions increases the negative contribution of the world dairy sector to the environment and brings large economic losses to dairy farmers and the entire...

Current approaches to study choline bioavailability do not account for the ruminal or postruminal bacterial degradation of choline to trimethylamine (TMA) and TMA N-oxide (TMAO). To evaluate choline bioavailability, 8 multiparous Holstein cows (184 ± 109 d in milk) were enrolled in a study with a 4 × 4 Latin square design. Treatments were (1) 0 g/d of supplemental choline chloride (CTR), (2) 16.8 g/d of unprotected choline chloride (CC) delivered as a continuous ruminal infusion...
