Introduction Lucerne is the main grazed forage of Argentina. However, there is a large yield and consumption gap on most dairy and beef farms. Jáuregui et al. (2019) indicated that < 5 t ha -1 are consumed on average on dairy farms. There is potential to close the gap by increased grazing frequency, particularly during periods of high growth such as spring (Jáuregui et al., 2022). However, the long-term effects of such management on lucerne persistence...

Israel is located in the eastern basin of the Mediterranean Sea and is characterized by a subtropical climate. Summer lasts from June to October and is characterized in most regions of the country by high temperatures and humidity at all hours of the day, but no rain at all. The Israeli dairy industry has about 120,000 cows that produce close to 1.5 billion liters per year. The annual milk yield per cow is the highest in the world and stood at more than 12,000 liters in 2021. The...

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. ...

1. Introduction While formaldehyde (FA) is naturally present as a low concentration metabolic intermediate in the cells of most living organisms [1,2], it is also found in several foods [1–3]. However, the presence of FA in milk, whether for direct consumption or for processing, can be caused by the direct addition of this compound as an “unapproved” preservative to extend its shelf life at room temperature due to its antimicrobial action [4,5] or by the...

INTRODUCTION Despite the growing concern for animal welfare, pain control in farm animals is still neglected (CANOZZI et al., 2020; HEWSON et al., 2007; HUXLEY & WHAY, 2006; LORENA et al., 2013). Until recently, this was partly due to the lack of precise instruments to assess pain (DOCKWEILER et al., 2013). In cattle, several zootechnical practices culminate in acute perioperative pain that can become chronic or neuropathic if preventive measures are not taken. The most...

Increasing the level of nutrition provided to dairy calves in the first weeks of life has resulted in several benefits such as decreased morbidity and mortality, faster recovery from disease, decreased age at first calving, improved mammary development, and increased milk production as an adult. What causes abomasal...

Yeasts are single-celled, facultative anaerobic eukaryotes that are prevalent in various fermented feeds. Yeasts can negatively affect silage quality by metabolizing available nutrients within the feed which leads to dry matter loss and decreased nutritive value, and by producing ethanol which can lead to off flavors in milk when consumed. Yeasts also oxidize lactic acid, which increases silage pH and promotes the growth of organisms such as mycotoxin-producing molds. Although wild yeasts...

Calves require supplemental water early in life to support hydration, health, early grain intake, rumen development, and body growth. Supplying body water by feeding milk or milk substitute is not enough to optimize these performance factors. The rumen needs a separate source of pure water to feed the fermentation process that makes the rumen grow. ...

Heat stress can have a huge impact on all cows; reducing dry matter intake, suppressing immune responses and decreasing reproductive performance. Dr. Geoff Dahl takes a closer look at how heat stress affects late gestation cows and the additional toll heat stress takes on the resulting calf. ...

INTRODUCTION Balchem now manufactures a high-quality, ruminally protected choline product called ReaShure®-XC Rumen Protected Choline, the next generation of ReaShure which provides bioavailable choline in a more concentrated product. Choline is an essential nutrient that enables cows to utilize the fat (NEFA) mobilized from body stores. The production of NEFA is the cows’ natural way of managing negative energy balance during the early stages of lactation and...
