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...

Somatic cell count (SCC) is the total number of cells per milliliter of milk and is one of the main indicators of milk quality in dairy cows. Somatic cells are made of 2% mammary gland cells and around 98% white blood cells – leucocytes that are immune cells, produced by the cow’s immune system. As SCC are immune cells, the number found in the milk increases as a response to an immune challenge in the udder. This challenge is usually caused by pathogens and leads to inflammation....

Introduction Milk production losses in summer months are generally related to the negative impact of heat stress on cows in lactation and late gestation stages. In the last 4 decades, several studies have been carried out in different parts of the world to mitigate heat through the implementation of cooling systems. In recently published articles, the different benefits achieved by properly implementing these means were presented. Among these benefits can be seen those related...

Introduction Considering that milk is the only material produced by nature to function exclusively as a food source, since it constitutes a nutritional source complete, not surpassed by any other known to humans (Jay, 2009). This food consumption may represent differences in the quality of diets of people without access to adequate nutrition, especially among children. In this sense, in recent years, world milk production exceeds 600 million tons per year according to the...

In a previous article that I recently published, I dealt with the importance of drinking water and water for cooling the cows, when dealing with the summer heat. In this article, I would like to deal with another factor that I see as very important in the above-mentioned confrontation, and it is shade, or in other words, preventing the exposure of cows to direct and indirect solar radiation in the summer. Why is it important to protect cows from solar radiation in the summer? To...

1. Introduction Aflatoxin M1 (AFM1), it is one of five principal metabolites results from the hydroxylation process of Aflatoxin B1 (AFB1). Reaction of enzyme oxidase is associated to cytochrome P 450 of the microsomes within the hepatocytes [1–6]. During this oxidative process, AFB1 is successively transformed into two intermediates, Aflatoxicol (AFL) and Aflatoxicol M1, before turning into AFM1, and in this form it is excreted through milk or eggs [3]. Some...

This article is written at the end of July, the hottest part of the year here in Israel, when every return home from abroad is first accompanied by going to the fridge to drink a lot of cold water. I decided that this is the right time to write about the importance of water in the dairy farm, especially for those located in warm regions. The issue of water in the dairy farm is an essential element in achieving milk yield, production efficiency and high profitability, especially in the warm...
