Why use organic micro minerals? Use of organic micro minerals (Zn, Cu and Mn) has a positive effect on hoof health, udder health, reproduction and milk yield. How are inorganic micro minerals absorbed? Inorganic micro minerals have to be dissolved in the digestive fluid (is transformed into ionic form) and then bound to a suitable adjuvant...

A robust immune system is vital for dairy cows to live long, healthy, and productive lives. Multiple factors affect the immune system, and, arguably, good nutrition is one of the most significant keys to efficient immune function. Research shows a properly functioning immune system uses key diet components, including vitamins, minerals, energy, and antioxidants.
Vitamins Immune system function can be significantly impaired...

1. Introduction. The intensification of grazing dairy systems has led to an increase on the use of supplements and more recently on the use of total mixed rations (TMR) (Wales et al., 2013), particularly when imbalances between herbage production and herd requirements occur during the course of a year (Chilibroste et al., 2007; Wales et al., 2013). Increased levels of TMR...

Introduction Over millennia, grazing ruminants have, for the most part, evolved on the great grasslands of the world, ranging from the savanna and tropical grasslands of the equatorial regions to the temperate grasslands at slightly higher latitudes. Less extensive are the high-altitude alpine pasture and marginal tundra biomes, in which many unique distinctive breeds and species of livestock have evolved, which, although...

Introduction The seasonal effects of heat stress have tremendous impact on dairying in India. Adjustments in nutrition and feeding management can alleviate some of the negative effect on health and performance, but compared with environmental modification, manipulation of the cow’s diet specifically for heat stress, has little effect on productivity. Normal physiological processes require that the...

It seems that, day by day, the administration of adequate levels of cupper and zinc is gaining importance in this regard. In this sense, the use of organic minerals is almost unquestioned. What other nutritional strategies do you follow or have heard/read about? ...

Introduction The objective of this article is to briefly describe the most common ethanol coproducts, how they are produced, and typical nutrient compositions. Rapid growth of the ethanol industry in the United States over the last decade has generated large quantities of ethanol coproducts, which are now commonly available as feedstuffs for livestock. These coproducts are often added to livestock diets as a source...

Introduction There continues to be a lot of interest in corn silage harvested with a self-propelled forage harvester (SPFH) equipped with an aftermarket processor having cross-grooved processing rolls set for 2- to 3-mm roll gap and greater roll speed differential than has typically been used (32% versus 21%). Also, the developer of this processor recommends that the SPFH be set for a longer theoretical length of cut...

Introduction
The factors driving food selection, feeding and nutrition-related performance are multiple and complex. These complexities arise from the fact that the many nutrients obtained from foods usually cannot be considered in isolation, but interact in complex ways in their effects on animals. Most models of nutrition have ignored this complexity, rather opting for the simplifying assumption that the...

Introduction Fertility of dairy cow is reduced in last few decades with increased productivity. Reduced fertility may limit the profitability and sustainability of dairy farms. Fertility is a multi-factorial trait and it is affected by number of factors viz. genetic, environmental, dietary and management factors with their complex interactions which makes difficult to determine the exact reason. Stress could be one...

i have been recently visiting extensive dairy cows' farms where there were no precise control of animal feeding. Major part of the ration was based on grazing pasturelands, with some addition of silage (either corn or grass) and/or 2-4 kg of concentrates.
These production systems are different to the most widespread ones (intensive ones with precise animal feeding).
Do you have experience regarding tips/strategies to provide with feed additives to cows reared under extensive/semiextensive...

Productivity and longevity of dairy cows are greatly influenced by proper nutrition programs. Human-animal interaction in larger dairies is limited, and ailments detection relies heavily on employees. Metabolic disorders and their complications such as hypocalcaemia, fatty liver, ketosis, displaced abomasum, acidosis, and laminitis may result from dietary inadequacies. Early veterinary attention increases treatment effectiveness and reduces overall costs....

Sequencing of the bovine genome offers new opportunities to understand the biology of dairy cattle and provides the framework to identify the genetic basis for the improvements and animal differences in productive efficiency. The new areas of biomics era includes genomics (covering DNA), transcriptomics (RNA), proteomics (protein), metabolomics (metabolites) and systems biology (integrating all of these), with bioinformatics. Omics technologies help to design...

The reduction in roughage content of the ration, as a result of high-grain, is closely related to changes in milk fat test and has been associated with metabolic problems, such as acidosis, hoof problems, displaced abomasum, liver abscesses, and a general decline in health. Adequate fiber and/or quality forage promotes good health and better performance.
Terminologies used in describing the fiber content of rations are crude fiber, effective fiber, acid detergent fiber (ADF) and...

Abstract During natural grazing of pasture, ruminal bio hydrogenation of unsaturated fatty acids leads to the formation of intermediates which are known as CLA (conjugated linoleic acid) isomers. Some of them, like the trans-10/cis-12 isomer are responsible for the observed reduction on milk fat concentration under grazing conditions. Supplementing silage-concentrate diets of transition dairy cows with CLA will adjust the...
