Heat stress poses a significant challenge for dairy cows, particularly in warm climates, as it hampers their physiology, behavior, and milk production. A study carried out in Hungary and published recently (Journal of Thermal Biology 135, 2026) investigated the effect of increasing barn wind speed by using modern fans on cows' behavior and performance. The research took place in a large-scale dairy farm (1000 cows), with high yielding cows (average daily milk production above 50...

I. FOUNDATIONS OF ANIMAL NUTRITION Animal nutrition is the part of animal husbandry that studies the use of different foods – or, more specifically, the immediate principles that constitute them – to satisfy the needs of animals useful to man [2]. This is defined as the series of processes through which an organism acquires and assimilates food to promote its growth and replace worn or damaged tissues. The nutrients are fundamental for the animals to carry out their...

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,...

Pneumonia of calves is a respiratory disease caused by the entry of bacteria and respiratory viruses into the body of calves, which occurs at the age of two to five months, and is more common in closed places and in the winter season. The best prevention of this pneumonia disease in calves is to give colostrum to calves. ...

The negative effects of heat stress and ways to deal with them are currently among the most important research areas. The reason for this is clear, heat stress has become the greatest cause of economic losses to dairy herds, including in regions with a relatively temperate climate, which have only begun to feel the problem in recent years. Evidence of the importance of the issue can be found in the following figure, taken from a recently published article and reviewing the sharp...

INTRODUCTION Early detection of mastitis is considered to be the best method to allow the cows the best chance for prompt recovery. Most farms base mastitis detection on visualization of clinical signs such as swollen quarters or altered milk. However, on large farms that have hired workers for milking it may prove challenging to have good mastitis detection. Therefore, new technologies are being constantly tested to automatically detect mastitis in the milking...

Introduction In March 2024, the CDC and USDA reported the first-ever cases of HPAI A(H5N1) in dairy cattle in the United States. As of May 2025, over 1,000 herds across 17 states have been affected, with California among the hardest hit. This unprecedented outbreak has had a significant impact on milk production, animal health, and public confidence. The emergence of Highly Pathogenic Avian Influenza (H5N1) in California's dairy cattle since August 2024 has...

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. ...
