In view of the major changes taking place concerning the buying and selling of milk and milk products this is an appropriate time to consider ways and means to manipulate milk components. The replacement of the Milk Marketing Boards by voluntary co-operatives and the potential changes in the pricing of milk together with changes in consumer demand raises questions over breeding objectives in relation to the emphasis on milk, fat and protein.The total cow population in the United Kingdom (UK) in 1992 was 4.38 million of which 2.68 million were dairy cows. Prior to 1984 when quotas were introduced cow numbers remained relatively static over a period of 25 years. Since 1984 cow numbers have decreased steadily from 3.3 million to 2.68 million. The major dairy breeds together with their average yields and composition are shown in Table 1.

AbstractTesting blood and milk parameters as well as analysing the relationships among these markers is very useful for monitoring the internal homeostasis and health in high-yielding dairy cows during various production periods. The aim of the study was to assess the correlations (relationships) among macro-minerals, such as calcium (Ca), inorganic phosphorus (P), magnesium (Mg), other selected bone profile markers, such as total protein (TP), albumin, activity of alkaline phosphatase (ALP) measured in serum and selected milk components such as number of somatic cells (SCC), colony-forming units (CFU), milk fat (MF), milk protein (MP), milk lactose (ML), dry matter (DM), non-fat dry matter (FDM) and milk production in late-lactation cows. Both blood and milk samples were collected from 11 clinically healthy milking cows during the late-lactation period. The cows were examined once a day for 3 consecutive days resulting in 33 sets of blood and milk samples for laboratory and statistical analysis. Significant correlations were observed between: Mg and MP, Mg and FDM, ALP and SCC, TP and SCC, TP and MP, TP and FDM, albumin and MP, albumin and FDM, P and Mg, Mg and albumin, and between TP and albumin. When monitoring macro-mineral homeostasis and mammary gland health, especially in intensively fed high-yielding dairy cows correlations between these markers should be considered. The revealed correlations can allow for deeper comparative laboratory diagnostics of homeostasis and can be especially useful for laboratory monitoring of the potential risk of subclinical macro-mineral deficiency in high-yielding dairy cows.

SUMMARYBetween 1969 and 1990 strains ofStaphylococcus aureusfrom 359 outbreaks and sporadic cases of staphylococcal food poisoning in the United Kingdom were examined in the PHLS Food Hygiene Laboratory for the production of enterotoxin. In a number of instances the incriminated foods were also examined for the presence of enterotoxin. Strains from 79% of incidents produced enterotoxin A alone or together with another enterotoxin. The level ofS. aureuspresent in the foods ranged from no viableS. aureusdetected to 1.5 × 1010c.f.u./g with a median of 3.0 × 107c.f.u./g. Enterotoxin was detected in foods in the absence of viableS. aureusin only two outbreaks and in both cheese was the implicated food. Meat. poultry or their products were the vehicle in 75% of incidents with ham and chicken most frequently implicated. Other foods included fish and shellfish (7%) and milk and milk products (8%). Most contamination took place in the home followed by restaurants and shops. Seventy-one percent of the incident strains were lysed by phages of group III or I/III.

It is important for the dairy industry to be aware of the consequences of past selection policies. This can provide guidance on how to improve or change current breeding schemes. In addition it is important to know how much of current progress is due to breeding and how much to management. The objective of the study was to analyse genetic and phenotypic trends for the production traits (milk, fat and protein) using the results from the latest UK Individual Animal Model evaluations.

Since the early 1980's there has been a growing interest in the Italian Piemontese breed as a crossing sire breed for use on dairy cows in the United Kingdom. Early interest was centred on ease of calving, growth performance and carcass yields but more recently there have been claims that the Piemontese breed produces meat which ranks highly for tenderness. The aim of this study was to evaluate carcass and meat qualities of Piemontese - sired cattle out of the British dairy herd by comparing these characteristics with similar and contemporaneous Charolais - sired cattle.

The development of new technology and diverse consumer demand has increased the digital retail industry today. This also affects the way buyers / consumers get the goods and services they want. Consumers turn to e-commerce and cellular to make purchases that are usually done physically. This change in shopping style has been driven largely due to the emergence of many market places and platforms. This change will also have effect on the taxation of the transaction. The Government of India applies the Equalization Levy Rules (EQL) scheme which is categorized as PNBP (Non-Tax Revenues). While in the United Kingdom there is a Diverted Provit Tax (DPT) scheme. Whereas Indonesia has no more specific rules, there is only a Circular (Surat Edaran) that regulates the Affirmation of Tax Regulations on e-Commerce Transactions, namely SE / 62 / PJ / 2013 tax regulations e-commerce follows the income tax law and value added tax.
