Take Home Message US dairy industry sustainability is increasingly important as producers are challenged with increasing dairy product supply to meet the demands of the growing population, while maintaining the tradition of environmental stew ardship Advances in nutrition, management and genetics resulted in a four - fold improvement in milk yield between 1944 and 2007. This allowed the US dairy industry to produce 59% more milk using...

The fat percentage of milk or butterfat has a significant economic impact for dairy producers. In recent years, the fat increment in milk has varied from less than 7 cents per tenth of a percent butterfat above or below 3.5 percent fat in the milk to over 20 cents per tenth of a percent of fat. Recently, the fat content of milk accounted for approximately 50 percent of the total value of the milk. Although fat rarely accounts for 50 percent of the value of the milk, small variations in fat...

Implications Fluctuations in the milk fat market are driving demands from farmers for ways to control milk fat production and composition in dairy cows. The current models used to estimate dairy cow requirements and formulate diets cannot predict changes in milk fat. These models are based on energy and protein intake and do not consider the pattern of individual nutrients derived from digestion. Using published infusion studies, this...

INTRODUCTION Diets that are rich in concentrates and poor in forage have long been known to depress milk fat content in dairy cows. These reductions in milk fat content, which can reach 50% with little or no change in the yields of milk, milk protein, or lactose, are referred to as milk fat depression (MFD) . Several theories have been put forward to explain the causes of MFD (reviewed in Bauman and Griinari, 2001, 2003; Shingfield et al.,...

INTRODUCTION The practical and scientific knowledge obtained on the use of the Lactoperoxidase system (LPs) confirms its innocuity to human health (1), which allowed the lifting of the restriction that the system could not be used for milk products intended for international dairy market, in the Thirty-Second Session of the Commission Codex Alimentarius (2). The simple name of LPs generates confusion due to the association to hydrogen...

Here are some of the most asked questions about robotic milking systems. Answers are based on formal interviews with Canadian robot owners, Ontario milk quality records and European research studies.
How many cows will I have to cull because robots cannot milk them?
Ontario farmers reported 0-3 extra culls from an average herd size of 94 cows. These were typically cows with very close teat placement,...

Introduction The purpose of the heifer herd is to provide replacements for cows leaving the herd and to improve genetic progress. First-lactation cows significantly contribute to herd production and profit. A recommended goal for dairy replacement heifers is to calve at 24 months of age with a targeted post-calving body weight of 1,250 pounds. A common misconception is that this goal is either unattainable or uneconomical. Feeding heifers for...

Introduction Profit centered dairy farms strive to maximize milk price and control costs. One way to control costs is by minimizing the rate of disease. The most costly disease of dairy cattle is generally considered to be mastitis. Mastitis can cause both clinical and subclinical disease. On many farms, subclinical mastitis is the most economically important type of mastitis because of the long-term effect of chronic infections on total milk...

Take Home Messages Use of on-farm culture systems to direct mastitis therapy can result in reduced antibiotic usage & less discarded milk without changing the probability of achieving treatment success The accuracy of on farm culture is dependent on the ability of milking personnel to collect & process a sterile milk sample When performed properly, on farm culture systems are about 80% accurate. ...

INTRODUCTION Pakistan is primarily an agricultural based country and livestock plays a pivotal role in its economy, providing essential items of the human diet in the form of milk, meat and eggs. At present, livestock contributes about 51.8 per cent of agricultural value added and 11.3 per cent to the GDP (Government of Pakistan, 2008-09). The estimated total number of livestock in 2008-2009 was 154.3 million. Foreign earnings of the livestock...

Buffaloes are significant source of milk in this sub-continent contributing as high as 68.35% of the total milk yield in Pakistan, and 56.85% in total milk production in India. In addition to the milk, the buffalo contributes about 11.52% of the total ruminant meat, and about 2.7% of all meat produced in the region. The average annual growth rate in production was about 1.3%. Undoubtedly, majority of world´s buffalo meat...

The objective was to evaluate the effect of β-lactoglobulin ( β -lg) polymorphism and seasonality on milk composition (fat, lactose, total solids, milk urea nitrogen, total protein, true protein, casein and somatic cell counts) of Holstein and Girolando cows. Milk and blood samples from 278 Holsteins cows and 156 Girolando cows were taken during two dry seasons and two rainy seasons, for milk composition analysis and to determine ...

Advances in technology and research have had major impacts on dairy management practices and performance of dairy cattle. With higher levels of milk production, there is a continuing increase in the requirements for energy, protein, fiber, minerals and vitamins. Also, just as important as the nutritional needs of high producing cows are the various management strategies needed to achieve and maintain those higher levels of milk production. In short, the many...

ABSTRACT The present research was conducted to determine effects of high temperature (120 °C) on milk proteins. In the first half of the experiment, the protein contents of the selected milk samples at room temperature were determined by Eko-Milk analyzer. Afterwards the milk samples were subjected for the temperature treatment in autoclave at 120 °C for 20 minutes and protein contents of the milk were...

ABSTRACT: Milk is the product of various biological reactions occurring inside the animal's body coupled with external environmental factors. The unfavorable subtropical conditions are not only affecting the quantity of milk but also its quality. The present study was designed to investigate the effect of physiological states and management on milk composition and yield in crossbred cattle. A total of 58 crossbred cows were selected from a large...

Almost a year has passed since the eruption of the melamine-tainted milk scandal that still reverberates across the globe; China's dairy industry is recovering steadily, albeit under a large current of sweeping changes.
Before the massive scandal that unravelled last September which killed six infants and sickened some 300,000 children, the use of melamine to artificially boost protein content in milk products was a common industry practice and an open trade...

The genetic predisposition of cows has an effect on the fat and protein content of their milk. Researchers at Wageningen University have spent the past few years examining the scope and significance of genetic variation between cows for the differences in quality characteristics of milk. They have discovered a number of genes that contribute to this genetic variation. The research was carried out as part of the large-scale Milk Genomics project that Wageningen...

Scientists are endeavouring to combine knowledge of the composition of milk with knowledge of the natural variation in the cow's inherited traits. The aim is to be able to select cows on the basis of specific milk qualities. The future will probably not give us milkshakes or yoghurt straight from the udder. And yet - perhaps a new Danish-Swedish research project that will be launched at the Faculty of Agricultural Sciences, Aarhus University, will in the future...
