Subclinical Ketosis On Dairy Cows In Transition Period In Farms With Contrasting Butyric Acid Contents In Silages

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract This study examines the relationship between subclinical ketosis (SCK) in dairy cows and the butyric acid content of the silage used in their feeding. Twenty commercial farms were monitored over a period of 12 months. The feed at each farm and the silages used in its ration were sampled monthly for proximal analysis and for volatile fatty acid analysis. A total of 2857 urine samples were taken from 1112 cows to examine the ketonuria from about 30 days prepartum to 100 postpartum. Wide variation was recorded in the quality of silages used in the preparation of diets. Approximately 80% of the urine samples analyzed had no detectable ketone bodies, 16% returned values indicative of slight SCK, and the remainder, 4%, showed symptoms of ketosis. Most of the cases of hyperkenuria were associated with the butyric acid content of the silage used (; ). As the metabolizable energy content of the feed was similar, no relationship w Continue reading >>

    had the vet out today with a 2nd calver,calved about 2wks with a case of ketosis,the vet went on to tell me about a bolus that they had only started to supply called kextone,he didn't know a lot about it because anyone that has used it hasn't had anything calved yet or long enough to know,what he did say on the down side was that it can blow up a big calf, the cost is £30 and you give it 4wks before calving,has anyone used such a thing,TIA

    It's actually a legal Monensin (Rumensin) bolus. My vet says they work very well. He has several farmers dosing every cow -though not to sure whether it's just for ketosis They cost about £30 and the cow gives an extra £60 worth of milk. Perhaps I'm just being cynical but no doubt they will find a "medical" reason to give it to beef cattle before long.

    My vet gave me one in the spring to use on a young bull that was suffering badly from recurring bloat on grass. I wanted to use him for breeding so wasnt keen on a dart.
    It worked very well and very quickly

  • How To Prevent Ketosis In Dairy Cows

    Years ago, I would lean over the feed bunk and smell the breath of a ketosis-suspect dairy cow. It convinced me that it had either bad breath or glue (acetone) breathing ketosis. Since then, I’ve come a long way. Dairy nutritionists like myself and dairy producers now have access to modern BHB (Beta-hydroxybutyrate) milk tests through regular Canwest DHI testing or from on-farm keto-testing kits. By detecting ketosis in problematic cows and imp ...

  • What Is Acidosis In Dairy Cows?

    Most cows are not fed corn. As a matter of fact most cattle aren't even on a high-grain diet for most, if not all, of their lives. Most cattle are actually grass-fed. Just not grass-finished. There's around 89 million beef cattle in the US, 9.3 million dairy cattle and 12.1 million cattle currently in the feedlot being finished (that according to USDA statistics from July 1, 2015). The 89 million beef cattle are breeding cattle: Beef cows, replac ...

  • Acidosis In Dairy Cows

    Managing disease can be a frustrating proposition. This Guide can help you identify which disease is damaging your cattle. Rumen acidosis is a metabolic disease of cattle. Like most metabolic diseases it is important to remember that for every cow that shows clinical signs, there will be several more which are affected sub-clinically. Acidosis is said to occur when the pH of the rumen falls to less than 5.5 (normal is 6.5 to 7.0). In many cases t ...

  • What Is Ketosis In Cows

    Not to be confused with Ketoacidosis. Ketosis is a metabolic state in which some of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides energy. Ketosis is a result of metabolizing fat to provide energy. Ketosis is a nutritional process characterised by serum concentrations of ketone bodies over 0.5 mM, with low and stable levels of insulin and blood glucose.[1][2] It ...

  • Why Do Cows Get Ketosis

    A couple similar questions have been asked on this already, and my responses to both can be seen here: Why do cows grow so big eating only grass? and How do cows get enough nutrition by just eating grass? Both animals are ruminants, which means they have multiple forestomachs designed for digesting plant matter, and to house quite the ecology of anaerobic bacteria, fungi and protozoa all which actively break down the bonds of cellulose with an en ...

    It obviously depends on the nature of the wound. *This examination should only be attempted by an experienced animal handler, as cows are big animals and they can move surprisingly fast, especially when irritated. (Really, seriously, just call a vet unless you like getting kicked and/or stepped on by a 1,200 lb bovine. This answer is meant for entertainment only.) Approach the cow and inspect the wound. The wound should be disinfected with someth ...
