Additives and feedstuffs in dairy cattle nutrition
Welcome to the page about Additives and feedstuffs in dairy cattle nutrition of Engormix; a source of knowledge on Additives and feedstuffs in dairy cattle nutrition.
Dr. Claudia Parys, responsible for the ruminant portfolio at Evonik Animal Nutrition, shares the inspiration behind developing a natural, capsaicinoid-rich solution designed to improve nutrient supply and milk production in lactating dairy cows. She also explains how this approach differs from traditional nutritional products and its unique benefits for dairy farming.

A cow’s biology and genetics set the stage for her milk production potential. Thanks to genomics, the pace of genetic progress has accelerated in recent years, pushing that potential ever higher. But are we feeding cows to match it? Today’s dairy cows can achieve more with better nutrition, yet their ability to physically consume enough nutrients lags behind their rising requirements. ...

Spotlight: “The interaction between lysine and methionine in increasing milk fat and feed efficiency is a perfect example of why balancing for all essential amino acids is so important. In an ideal world, we could provide exactly the required amount of essential amino acids, but this is difficult with only rumen protected forms of lysine and methionine currently available in the market. In this case, if we only balance for lysine or methionine instead of both, we could be missing out...

During the perinatal period (within three weeks postpartum), dairy cows are in a state of negative energy balance, with fat tissue breaking down and a large amount of non-esterified fatty acids (NEFA) flowing into the liver. Moderate lipolysis and a moderate release of NEFA are beneficial for cows to successfully cope with negative energy balance, but excessive lipolysis leads to high concentrations of NEFA flowing into the liver beyond the ability of liver cells to oxidize fatty acids for...

1. Introduction Dairy cows have to afford several endocrine, metabolic, reproductive, and immunological challenges during the productive cycle. These challenges are particularly pronounced during the transition period (TP), when cows experience a reduction in dry matter intake (DMI), leading to negative energy balance (NEB), lipomobilization, and body mass loss. This metabolic stress occurs alongside drastic changes in hormone concentrations, decreased blood calcium levels, and...

1. Introduction Lactoperoxidase is one of the main protein enzymes in milk, and is found in average concentrations of 30 mg/L, much higher than the biological requirements for an optimal enzymatic reaction [1]. This enzyme belongs to the group of oxidoreductases, and is responsible for the bactericidal and bacteriostatic phase during the first hours after milking [2-4]. Lactoperoxidase enzyme is a milk protein with special biological activities, and particularly those that are...

Fatty acids (FA) are organic molecules classified by their number of carbon atoms and number and position of double bonds between these carbon atoms (Maulucci et al., 2016). Fatty acids fulfill various functions, and they are important sources of energy. Also, FA are precursors for the biosynthesis of phospholipids, for the generation of numerous ligands for different types of receptors (Buczynski et al., 2009), and are the source of lipid mediators, particularly of molecules associated with...

Multiple EAA drive milk protein production in dairy cows, including His, Ile, Leu, Lys, Met, and Thr. Therefore, determining bioavailability of rumen-protected AA (RPAA) is essential for optimal EAA supply. We aimed to evaluate bioavailability of lipid-encapsulated prototypes of His, Ile, Lys, Met, and Thr and an isopropyl ester of 2-hydroxy-4- (methylthio) butanoic acid (HMBi). Six Holstein heifers (518 ± 28 kg BW) were allocated in a 6 × 8 Youden square design, with 8 periods...

Global food demand is set to double by 2050 in line with UN estimates that the world population will increase from today’s 7.6 billion to reach 9.8 billion over the next 26 years. To keep pace with such growth, agricultural systems throughout the world will need to provide extra food to feed the rising number of people. While this is a daunting prospect, such enormous growth will also provide opportunities and challenge for the dairy sector as we seek to keep providing the global...

The role of Actisaf® Sc 47 in modern dairy nutrition Improving feed efficiency is one of the most effective strategies to reduce GHG emissions, whilst still increasing milk production. As global demands shift from pursuing maximum output, irrespective of the resources used, to the pursuit of balanced sustainability in which efficient production is measured against environmental concerns and the use of finite resources, so similar changes in approach are...

Overview The transition period is defined as approximately 21 days before and after calving, during which dry matter intake is restricted while the demand for nutrients increases rapidly and there are intense metabolic and hormonal changes which impact the whole lactation. These changes result in negative nutrient balance with attendant metabolic disorders and greater risk of disease incidences which affect foetal growth together with cow health, fertility, and milk production...

1. Introduction Both L-glutamate (Glu) and L-glutamine (Gln) are abundant amino acids (AAs) in plant, microbial, and animal proteins [1]. In the whole bodies of sheep and cattle, Glu and Gln are the third and eighth most abundant AAs, respectively. For comparison, the total content of these two AAs, along with other AAs, in feeds [e.g., Bermuda grass, distillers dried grains, and solubles (DDGS)], ruminal microbes, and skeletal muscle proteins is also relatively high, as summarized...

Dry period heat stress significantly reduces milk yield in the subsequent lactation in cows. Altered methylation patterns in mammary tissues is associated with the decline in milk yield. We hypothesized that as a methyl donor, choline (RPC) supplementation reverses similar patterns of methylation and thus productivity in heat-stressed dams. Late-gestation Holstein cows (n = 51) housed in freestall barns were enrolled to either heat stress (HT, n = 12), HT with RPC (HTC, n = 11), cooling (CL,...

Current approaches to study choline bioavailability do not account for the ruminal or postruminal bacterial degradation of choline to trimethylamine (TMA) and TMA N-oxide (TMAO). To evaluate choline bioavailability, 8 multiparous Holstein cows (184 ± 109 d in milk) were enrolled in a study with a 4 × 4 Latin square design. Treatments were (1) 0 g/d of supplemental choline chloride (CTR), (2) 16.8 g/d of unprotected choline chloride (CC) delivered as a continuous ruminal infusion...

The discovery of choline dates back to 1850s when French pharmacist, Théodore Gobley discovered a group of phospholipids that he named lecithin. Seventy years later, during the discovery of insulin by Frederick Banting, his student Charles Best noticed that depancreatized dogs developed hepatic lipidosis. Subsequently in the early 1930s, Best showed that supplementing lecithin reversed and prevented hepatic lipidosis in dogs and rats. It took another 67 years for dietary choline to be...
