Welcome to the page about Dairy cattle nutrition of Engormix; a source of knowledge on Dairy cattle nutrition.
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...

The debate as to the effectiveness of various forms of fat supplements in supplying the energy deficit to lactating dairy cows in early lactation is live. It is perhaps refreshing to review the general properties of the commercially available rumen-protected/inert fats.

Fat supplements generally carry the label...

INTRODUCTION The carbohydrate fraction, which includes neutral detergent fiber (NDF) and non-fiber carbohydrate (NFC), comprises approximately 70% of diets for lactating dairy cows (DM basis). Meeting a minimum forage-NDF guideline is important for providing sufficient physically-effective NDF (peNDF) to support good rumen function, while exceeding a maximum forage-NDF guideline may restrict dry matter intake (DMI) through rumen fill...

Introduction Dairy farmers might be over-feeding a large proportion of lactating cows when they feed the same ration to a large group of animals. Diets are normally formulated to provide enough nutrients to the most productive animals, which in turn gives extra nutrients to the less productive animals. Therefore, splitting lactating cows in smaller groups and offering group-specific feeding rations provides more precise...

Studies have demonstrated that heat-treating colostrum at 60°C for 60 minutes results in a significant reduction in colostral bacteria counts with no overall reduction in colostral IgG concentrations. Preweaned calves fed HT colostrum have enhanced efficiency of absorption of IgG and reduced morbidity. Despite these benefits, limited research exists to describe if the heat-treatment process harms other colostrum components. The objective of Study 1, described herein, was...

Dairy Cow Nutrition Nutrient requirements for lactating dairy cows vary with the stage and level of lactation, growth rate and stage of gestation. Most dairy producers in Arkansas feed grain in the parlor as the cows are being milked. This allows producers the opportunity to feed cows according to their level of production and to manage the amount and quality of grain that the cow is consuming. Figure 1 (page 2) shows the...

Enzymes have been used extensively in the diets of poultry and pigs, and as silage additives, but, until recently, not much in the diets of ruminants (Beauchemin et al., 1995; Beauchemin et al., 1999a; Yang et al., 1999), due to the view that feed enzymes would be rapidly degraded in the rumen before they could have any effect (Beauchemin et al., 1995; Beauchemin et al., 1999a; Kung et al., 2000; Bowman et al., 2002a) and due to the high cost of enzymes and inconsistency of responses (Yang et...

Summary The aim of the Australian Profit Ranking (APR) selection index for Australian dairy cattle is to improve the profitability of dairy farming and assigns weights to milk, fat and protein yield, daughter survival, daughter fertility, somatic cell count, live weight, temperament and likeability according to their contributions to profit and their correlations. Although the index partially captures gross efficiency, it does not account for...

Hello everybody, There is a dairy farm in Turkey. The avarage milk yield of the cows is about 32 lt/day. For 10-15 days, it has seen cecal dilatation and right displaced abomasum very often. As I know either cecal dilatation or displaced abomasum is related wtih particul size of TMR and low forage: concantre ratio in TMR. But the interesting thing is, none of them is wrong. I mean there is 45% of forage on the TMR and the particle size is like to be. And the...

Preamble. Green forage is the most preferred feed for dairy cows by the farmers. They feel happy while feeding their cows with green succulent fodder. In advanced countries the cows are let loose on pasture land to graze and forage at their free will. When the above facilities are unavailable farmers have to depend on dry fodder. Fiber is the slowly digested or indigestible material in...

Take home messages Application of high-throughput technologies (e.g. microarrays, next-generation sequencing) in a systems biology framework to study the interactions of physiological state and nutrition on tissue function in livestock species is a powerful means to gain a holistic view of the underlying biological phenomena. Potential practical applications from applying such an approach in studies of mammary, adipose, and liver of dairy cows are...

Introduction Water constitutes 60 to 70 percent of a livestock animal's body. Water is necessary for maintaining body fluids and proper ion balance; digesting, absorbing and metabolizing nutrients; eliminating waste material and excess heat from the body; providing a fluid environment for the fetus; and transporting nutrients to and from body tissues. Dairy cattle get the water they need by drinking and consuming feed that contains water, as well...

INTRODUCTION Livestock in Pakistan are facing acute shortage of feed availability including concentrates, forages and pastures. Currently about 30 million tons of more feed is required to fulfill the gap of 4.16 and 21.3 million tons of crude protein (CP) and total digestible nutrients (TDN) respectively for the existing strength of dairy animals (Sarwar, 2006). The prevailing trend to bring more cultivated area under cash crops has further...

Introduction Sugars are rapidly and extensively fermented in the rumen. Clearly, adding sugar to a diet already high in ruminally degraded carbohydrates should offer little benefit and could decrease digestibility of fiber, whereas diets that have less-than-optimal rumen degraded carbohydrate probably will benefit the most from addition of sugars. Therefore, dietary situations influence the optimum feeding rate of between 2.5 and 5% supplemental...
