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 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...

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...

INTRODUCTION Preservation of alfalfa as silage is becoming convenient due to the ease of mechanization and reduced susceptibility to weather damage (Khadem et al . 2009). Calberry et al . (2003); Bhandari et al. (2008) and Khadem et al. (2009) reported that cows fed on ration containing chopped alfalfa hay had lower intake than those fed on a diet containing chopped alfalfa silage. But similar milk yield and composition (Calberry et al ....

Introduction Many factors influence the composition of milk, the major components of which are water, fat, protein, lactose and minerals. Nutrition or dietary influences readily alter fat concentration and milk protein concentration. Fat concentration is the most sensitive to dietary changes and can vary over a range of nearly 3.0 percentage units. Dietary manipulation results in milk protein concentration changing...

INTRODUCTION Aflatoxins (AFs) in food and feed are recognized as a public health problem of considerable importance. Williams et al. (2004) estimated that 4.5 billion of the world’s population is exposed to AFs. Because security blankets in crops at pre-harvest and post-harvest level are not as strict as in developed countries, populations of developing countries are the most susceptible to aflatoxicosis illness (Williams et al., 2004). The same problem occurs with milk...

Introduction Suboptimal milk yield limits the U.S. dairy industry’s productive competitiveness, marginalizes efforts to reduce inputs into food production, and increases animal agriculture’s carbon footprint. There are a variety of circumstances in a cow’s life which result in hindered productivity including heat stress, rumen and hindgut acidosis, feed restriction, and psychological stress associated with normal animal practices (i.e., pen changes, weaning,...

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....

Providing both digestible fiber and energy (starch), corn silage is a primary forage source for many dairy farms around the world. But there can be complications to feeding this highly used raw feed source. The North America Dairy Team at Novus International is providing advice to the industry on how to avoid dips in dairy production during this seasonal transition. Transitioning to a new crop of corn silage has been shown to negatively impact dry matter intake,...

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...
