A relatively long heat wave swept through Israel and the Middle East region in mid-August 2025. As expected, reports were received from various regions of the country of a significant decrease in milk yield per cow. A previous review published on the association's website characterized the decrease in milk production following the heat wave. The purpose of the current article is to examine the effect of the increase in cows' heat load during the heat wave period and after it ended,...

Targeted Nutrition for Lower Nitrogen Output and Higher Dairy Stability

Dairy cows are often thought of as metabolic super athletes, requiring hard work and a herculean effort to achieve high milk production. In reality, it’s just the opposite. Productivity is an expression of health and vitality, not a result of the cow working under stress. Put a cow in a healthy environment, provide adequate nutrition and they’ll fully express their genetic potential in the form of exceptional milk production. Instead of involving hard...

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. ...

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...

Multiple EAA drive milk protein production in dairy cows, including His, Ile, Leu, Lys, Met, and Thr. Therefore, determining bioavailability of rumen-protected AA (RPAA) is essential for optimal EAA supply. We aimed to evaluate bioavailability of lipid-encapsulated prototypes of His, Ile, Lys, Met, and Thr and an isopropyl ester of 2-hydroxy-4- (methylthio) butanoic acid (HMBi). Six Holstein heifers (518 ± 28 kg BW) were allocated in a 6 × 8 Youden square design, with 8 periods...

With the recent withdrawal of Kexxtone from the European market, dairy farmers are seeking new solutions for managing the challenging transition period of dairy cows. ReaShure®-XC Precision Release Choline and NiaShure™ Precision Release Niacin offer an innovative and comprehensive approach to improving cow health, increasing milk production, and promoting calf health and productivity. Both products can help support transition cow health, resulting in a significant return on...

Global food demand is set to double by 2050 in line with UN estimates that the world population will increase from today’s 7.6 billion to reach 9.8 billion over the next 26 years. To keep pace with such growth, agricultural systems throughout the world will need to provide extra food to feed the rising number of people. While this is a daunting prospect, such enormous growth will also provide opportunities and challenge for the dairy sector as we seek to keep providing the global...

Our objective was to evaluate changes in choline metabolism including bacterial degradation to trimethylamine (TMA), methyl group transfer, and bioavailability in pregnant and lactating cows. Six multiparous, rumen-cannulated Holstein cows were enrolled in a study design where they were abomasally infused 18 g/d choline chloride (CC; dissolved in water; 170 mL/h) for a 5-d experimental period at −3 wk from expected due date and again at 2 wk postpartum. The stable-isotope...

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...

Amino acids (AA) undergo complex metabolism for protein synthesis or excretion after oxidation. We investigated the fate of metabolizable Lys via continuous abomasal infusion of 15 N-Lys. Four rumen-cannulated Holstein cows (147.0 ± 63.2 d in milk, 49.4 ± 9.5 kg milk yield) received 0.6 g/d of 15 N-Lys into the abomasum for 5 d. Cows were offered a common diet (16.6% crude protein; 89% of metabolizable Lys requirement) once daily for an ad libitum intake....

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...

This study aimed to evaluate the effects of four dietary lipid supplements on milk composition and butter properties. Ten multiparous Holstein cows (64±21 days in milk) were used in a replicated 5×5 Latin square design. Cows received a basal diet without supplementation (CTL) or with 2% (dry matter basis) fatty acids (FA) provided as soybean oil (SO), calcium salts of palm FA (CS), hydrogenated tallow FA (HT) or palmitic acid-enriched supplement (PA). Treatment periods lasted 21...

Dairy cows are truly remarkable creatures. Consider the rapid transformation of a modern Holstein cow, going from zero to producing as many as 50 kilograms of energy-corrected milk per day in just 3 to 4 weeks of lactation. Such incredible production demands dynamic and integrated adaptations in multiple tissues to cope with...

When talking about the negative impact of heat stress on milk production, we usually refer to the impact on milk volume (liters per cow per day or per lactation). The reality is that this is only part of the problem, which causes economic losses to farmers and dairy industry. As will be presented in this article, heat stress negatively affects milk fat and protein content and reduce milk quality, by increasing milk Somatic Cell Count (SCC) and bacterial count. In some cases, especially in...
