On July 5, 1996, scientists at Scotland’s Roslin Institute succeeded in cloning the first livestock mammal using a somatic cell obtained from an adult animal. To produce Dolly the sheep, researchers replaced the nucleus of an egg with a nucleus isolated from the udder of a six-year old sheep. Roslin Institute announced Dolly’s birth in early 1997. The news incited visions of herds of cloned ani...

During last several decades, arsenic and its compounds have been characterized as major environmental pollutants thus potential causes of both human animals poisoning. Water milk are one the sources arsenic. In this study, influence from drinking water on concentration in cow`s was investigated, well udder parenchyma. The study included twenty cows six farms Banat. which blood samples were take...

Skin pathologies of the teat and udder are rare but a difficult to diagnose challenge for large animal practitioners. Due to their localisation, the milkability can be compromised partly or completely so that the economic value of the animals is seriously at risk. Skin pathologies of the udder can be of infectious or non-infectious nature. Most prevalent non-infectious skin lesions are primaril...

There is little doubt that raw milk is the most scrutinized agricultural commodity. Appendix N of the Pasteurized Milk Ordinance requires that all bulk tank milk be tested for beta-lactam antibiotics. This document also sets the regulatory levels for somatic cell counts (SCC) and bacteria levels in raw bulk tank milk. Milk processors are required to perform the regulatory testing. Many progress...

An electromagnetic method was adapted to quantitatively measure blood flow through an external pudic artery of the udder in lactating cows during several months. Blood flow through the ipsilateral external pudic vein was blocked while blood was taken from a subcutaneous abdominal vein. Blood flow to milk yield ratio amounted to a mean value of 507:1 in three cows. Peak milk yield occurred befor...
