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 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...
“These are very exciting results that come at an opportune time,” says Sabrina Zettell, Nutrition & Technical Service Manager with CBS Bio Platforms, which developed the technology and conducted the trial. ...
CBS Bio Platforms feed additive Optimax E shows breakthrough results to help dairy farms optimize efficient sustainable high yielding production
Calgary, ALBERTA – A novel bio-catalyst feed technology shows breakthrough results to help dairy farmers and their...
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....
Dr. Karen Luchterhand, Ruminant Technical Service Manager at Novus International, points out how cow comfort impact milk production, what is the C.O.W.S.® Program, the challenges dairy producers are facing in the US and LATAM, during AMVEB 2019 in México....
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...
Introduction Biological rhythms are repeating patterns that are driven by time-keeping mechanisms within the animal and are adaptive as they coordinate physiology and metabolism with the external environment. The dairy cow has a well-recognized natural daily pattern of feed intake and milk synthesis and an annual rhythm of milk composition, but regulation of these rhythms has not been well described in the literature or well considered in current dairy management. We commonly...
Watch this short video and listen to the success story of Italian farm Società Agricola Zilio, 1,100 cows in milk. “We are open to new idea, but they must work. And I must say” - Alex Zilio comments – “that thanks to Balchem ??expertise, and the inclusion of ReaShure-XC and NiaShure in the ration, we saw an increase in milk production of about 2.4 liters/head/day, without forgetting the significant reduction of post-partum events such as retained placenta, dislocation of the abomasum and...
Early-lactation dairy cows have high energy demand for milk production. Often the energy intake in this period is not enough to meet their requirements and the cows often face negative energy balance that may lead to metabolic...
