… against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact. Four different groups of animals were included in this study …
… of INDF, and increased concentration and yield of milk protein, decreased milk urea content and improved feed efficiency (p
… for example non-esterified fatty acid (NEFA), beta-hydroxybutyrate (BHB) and urea. All these parameters have been negatively associated with several fertility traits, and can probably be used as indirect selection criteria of fertility in breeding programs. Research has also …
… 10 percentage units to 50 % of total N), probably due to mineralization of urea, after which time net mineralization stopped. However, the slurry continued to show slow net mineralization (only a few percent) to the end of the 56-day period. Between 35-50% of the total nitrogen …
… hocks were presence of S. aureus in milk, presence of hock lesions, high milk urea value, and increased milk yield. Factors associated with lack of S. aureus on hocks were increasing lactation number. Risk factors associated with S. aureus in milk and on hocks were not identical …
utfodringsstrategier och konserveringsmetoder
… synthesize microbial proteins and the excess of nitrogen will be excreted as urea in the urine. If the nitrogen is not fixated by forage crops it will evaporate to the atmosphere as ammoniac which eventually contributes to nitrogen over-fertilizing when the rain falls down. The …
… the highest pea content. On the other hand, no higher values of blood urea levels were detected for PR compared to the other treatments. Although the amino acid profile in the dietary protein differed among treatments, there were only a small difference detected of the amino …
… De förändringar som påvisats är ökade koncentrationer av kreatinin och urea i blodet samt papillär nekros och tubulär degeneration. Vid jämförelsen mellan icke-selektiva och selektiva NSAIDs blir osäkerheten stor eftersom studierna är genomförda på olika sätt och att forskarna …
påverkan på näringstillförseln och mjölkens fettsyra-sammansättning hos 5 sydsvenska mjölkkobesättningar
… Efter försöket skickades mjölkproverna på analys där halter av fett, protein, urea, laktos och fria fettsyror samt andelen konjugerad linolsyra (CLA), Palmitinsyra (C16:0) och Stearinsyra (C18:0) uppmättes. Mättade, omättade, enkelomättade, fleromättade, trans-, omega-3, omega-6 …
… in the milk; progesterone, betahydroxybutyrate, lactate dehydrogenase and urea. In this study the focus will be on progesterone which is a hormone produced by the corpus luteum. The concentration of this hormone indicates where the cow is in her estrus cycle. The study was …
… för att vänja in sina djur på en tanninrik diet. En metod är att tillsätta urea till fodret och en annan är att tillåta blad från ek att dra i vatten innan utfodring för att minska halten av tannin i födan. Detta är ett sätt att tillvänja djurens våmkultur till tanniner. Då kor …
… in period two was significantly higher for the more frequent milked side. The urea content in the milk was not significantly affected by the treatment in period two. In conclusion minor effects on protein content due to frequent milking were observed, while plasmin activity …
samband med hepatit/pankreatit?
… in the gastric mucosa neutralize the gastric acid through production of urease that hydrolyses urea to ammonia and bicarbonate. Ammonia has toxic effects on the gastric epithelium. The bacteria make way through the gastric mucus layer and adhere to epithelial cells in the …
… protein of WWDG is of rumen degradable character which can affect the value of urea in milk. Amino acid composition of the WWDG is not optimal for lactating dairy cows when the first limiting amino acid is methionine. The phosphorus content of WWDG is higher than that of …
