Scientists breed skim milk-producing cow

Date: 29.5.2007 

Officials at the biotech firm, ViaLactia, said the new breeding program would allow them to gain a significant foothold in the world's food industry by marketing to health-conscious consumers, The Times of London said Sunday. ViaLactia's chief scientist, Russell Snell, said the cow's milk is significantly healthier in three ways. "She produces a normal level of protein in her milk but substantially less fat, and the fat she does produce has much more unsaturated fat," Snell said. "She also produces milk with very high levels of omega3 oils." "ScienceDaily":[ http://www.sciencedaily.com/upi/index.php?feed=Science&article=UPI-1-20070527-20541200-bc-newzealand-skimmilk.xml]

Rice with human proteins to take root in Kansas - Rice modified to express proteins often found in breast milk will be planted in Kansas It's certainly not the first crop designed to produce pharmaceutical proteins given the go-ahead in the United States or elsewhere (see 'Turning plants into protein factories') The rice strains, made by Ventria Bioscience in Sacramento, California, produce lysozyme, lactoferrin and human serum albumin in their seeds Whole article Nature (21.5.2007)

Mycobacterium avium Subspecies paratuberculosis Cultured from Locally and Commercially Pasteurized Cow's Milk in the Czech Republic - Between November 2002 and April 2003, 244 bottles and cartons of commercially pasteurized cow's milk were obtained at random from retail outlets throughout the Czech Republic During the same period, samples of raw milk and of milk that was subsequently subjected to a minimum of 71 paratuberculosis infection, and from one herd, herd C, without infection Colonies were characterized by morphology, Ziehl-Neelsen staining, mycobactin J dependency, and IS900 PCR results paratuberculosis was also cultured from 2 of 100 (2%) cartons of locally pasteurized milk derived from infected herds A and B and from 0 of 100 cartons of milk from uninfected herd C paratuberculosis Wuhib Y Veterinary Research Institute, Brno, Dairy Research Institute, Prague, Czech Republic2 Sourcetool=pmcentrez&artid=1065148 (15.5.2006)

Allergen-responsive CD4+CD25+ Regulatory T Cells in Children who Have Outgrown Cow's Milk Allergy - Cow's milk allergy in children is often of short duration, which makes this disorder an interesting clinical model for studies of tolerance to dietary antigens Here, we studied T cell responses in 21 initially allergic children who, after a milk-free period of >2 mo, had cow's milk reintroduced to their diet No significant difference in proliferative activity stimulated by the polyclonal mitogen phytohemagglutinin was observed between the two groups Source (5.4.2006)

Production and Processing of Milk from Transgenic Goats Expressing Human Lysozyme in the Mammary Gland - The potential for applying biotechnology to benefit animal agriculture and food production has long been speculated We generated one line of transgenic goats as a model for the dairy cow designed to express human lysozyme in the mammary gland Milk from transgenic animals had a shorter rennet clotting time and increased curd strength Source (8.2.2006)
