Matheus Paez Martins Narciso (University of Alberta) Although the importance of pH and short-chain fatty acids on rumen development are well known, their impact on the small and large intestine are unclear. This study investigated the effects of ruminal short-chain fatty acid concentrations ([SCFA]) and pH on the rumen and intestine of calves. Holstein bull calves (n = 32) were individually housed and fed milk replacer (900 g/d) twice daily and calf...

Brian Aldridge (University of Illinois) Biological health is a complex topic of discussion and is often misunderstood as existing as a binary state in terms of the presence or absence of disease. In many ways, it is useful to explain health at a population or system level as the existence of individuals in 1 of 3 states: those in a healthy condition, those with a prediseased status, and those in a diseased state. At a systems level, it is useful to...

Mohamed Donia (University of Illinois) Ruminant neonates rely on colostral immunoglobulin and nutrients to support health, welfare, and performance, by protecting against infectious disease and providing early life resilience. Recent evidence suggests that transferred colostral cells also contribute to neonatal immunity under controlled experimental conditions. This study provides evidence that colostral cells enhance neonatal resilience to routine,...

Lipid encapsulation has proved to be a valuable tool for protecting nutrients from degradation during processing, storage and digestion and making them available for absorption by the animal. Over the last years, many new encapsulated nutrients have entered the market. These products, and the processes that create them, differ greatly in design, technology, and unfortunately, performance. High quality encapsulated nutrients can provide nutritionists with a great deal of flexibility to...

Summer heat stress is currently one of the biggest causes of economic losses to the global dairy industry, especially in the hot regions of the world. The International Dairy Federation (IDF) decided to deal with the problem and established recently an expert's committee to examine the issue and recommend ways to deal with it at the global level. After being recommended by the Israeli Dairy Board to participate in this committee, I found myself serving in a central role in...

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...

1. Introduction Antimicrobial resistance (AMR) is one of the top 10 global threats to public health and is thought to be partly driven by the widespread use of antibiotics in food-producing animals (WHO, 2021). Globally, a greater proportion of the tonnage of all antibiotics sold are for use in food-producing animal sectors compared to for use in humans (Van Boeckel et al., 2017). In 2017, an estimated 93 million kilograms of active ingredient were sold worldwide for use in...

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...

INTRODUCTION The profitability of dairy farms is an increasing concern in many economies around the world (Ellis et al., 2020; Ojo et al., 2020). This is the result of continuous economic, political, social, and environmental factors affecting different countries and regions (O’Leary et al., 2018; Ramsbottom et al., 2021). Therefore, dairy farmers are continuously searching and updating strategies and technologies that can improve the dairy farm technical and economic...

Post-calving care for cattle is a critical phase in dairy farming that significantly impacts the health and productivity of both cows and their offspring. Proper care during this period is essential to ensure a smooth transition from pregnancy to lactation and to prevent potential complications. In this article, we will delve into the key aspects of post-calving care for cattle and why it is of utmost importance. Understanding the Significance of Post-Calving Care Calving...

An article dealing with this topic was recently published in the prestigious journal of the dairy industry, Journal of Dairy Science (Espinoza-Sandoval et. al., JDS 106: 2023). The article examines, using a statistical model, the feasibility of investing in cooling the cows in the summer in various countries around the Mediterranean Sea (Europe, North Africa and the Middle East), where there are different “climate zones” regarding dairy farming. The model presented in this...

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...
