the effects of high non fibrous carbohydrates diet on milk production, inflammation and molecular mechanism of innate immunity in lactating dairy cows
پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Fast biosensor immunoassays for the detection of cows' milk in the milk of ewes and goats.
Two monoclonal antibodies (MAb) raised against bovine kappa-casein were developed and applied in an automated optical biosensor (Biacore 3000) to create easy and fast direct and inhibition biosensor immunoassays (BIA) for the detection of cows' milk in the milk of ewes and goats. With both assay formats, low limits of detection (<01%) and fast run times (around 5 min) were obtained. For sample ...
متن کاملApplication of a duplex-PCR for detection of cows' milk in goats' milk.
A duplex-PCR method, with 2 pairs of primers recognizing sequences of mitochondrial D-loop region, was developed to identify cows' milk in the milk of goats. The PCR was shown to be specific and sensitive, enabling the detection of less than 1% of cows' milk added to the milk of goats. Simultaneous use of a primer pair for goats' and cows' mitochondrial DNA fragment prevented false negative res...
متن کاملMycobacterium bovis detection from milk of negative skin test cows
MycobacteriuM bovis is the bovine tuberculosis (bTB) agent, which is still an important infection in bovine herds. Apart from this, bTB is also a zoonotic disease, and human beings can be infected by the consumption of non-pasteurised milk and its derivatives (Michel and others 2010). Hence, bTB is still endemic worldwide (Humblet and others 2009). The single intradermal test (SIT) is a worldwi...
متن کاملOn Predicting Milk Yield and Detection of Ill Cows
The fully automated milking system VMS has different functions which complements the actual milking of cows. This master thesis presents a method to improve the calculation of milk yield in dairy cows for the VMS. This report also investigates if it is possible to improve the algorithm for finding cows with mastitis (udder inflammation). The correctness of the prediction of milk yield is import...
