Metabolic Disorders of Dairy Cattle
نویسنده
چکیده
Dairy cattle metabolic disorders, which are diseases related to disturbance of one or more metabolic processes in the organism are discussed in this overview. The transition period which includes three weeks before and three weeks after parturition is very critical for dairy cows. This period of time is associated with multiple changes including hormonal changes, moving from non-lactating to lactating state as well as a major drop in feed intake and switching of the diet from a roughage-based diet (i.e. hay and grass) into a diet rich in rapidly fermentable carbohydrates (i.e. high-grain diets). One in two dairy cows in a herd is affected by one or multiple metabolic disorders. Although the etiology and pathogenesis of most metabolic disorders is not fully understood, different preventive and treatment strategies have been developed during the years. A more detailed and comprehensive treatise on cattle metabolic disorders can be obtained from several scientific review articles which have been listed and annotated in the bibliography section of this chapter.

Effect of Metabolic Stress on Ovarian Activity and Reproductive Performance of Dairy Cattle: A Review
Reproductive efficiency in dairy cattle has been decreased over the last 5 decades despite significant gains in genetic selection, improved reproductive technologies and nutritional care. In high-yielding dairy cattle, the negative energy balance (NEB) during the first week post-partum adversely affects ovarian activity, mainly follicle growth and steroidogenesis. Circulating levels of non-este...
متن کاملSituations Leading to Oxidative Stress in Dairy Cattle
Free radicals are normally produced by living organism, at controlled production rate they perform physiological functions as signal transduction molecules. However, situations leading to an overproduction that surpasses antioxidant capacity creates oxidative stress. Consequently, damage to the cell membrane, protein, DNA and cell death are observed. Dairy cattle are susceptible to oxidative st...
متن کاملEffect of Milk Urea Nitrogen of Dairy Cows in Relation to Breed
Milk urea nitrogen (MUN) of dairy cows was determined in relation to breed. A total of forty (40) Pabna and red Chittagong dairy cattle each of twenty (20) were selected to know the milk composition, nutritional status and milk urea nitrogen. Live weight of Pabna Cattle (187±14 kg) was higher than that of red Chittagong cattle (174±4 kg). In Pabna cattle milk yield (4.94 kg), minerals (0.15%) a...

In this study the causes of culling in 9 industrial dairy farms in northwest of Iran between 2008 to 2013 were investigated. The impact of various factors on culling was analyzed using the GLIMIX procedure of SAS 9.2. The results showed that from 5404 dairy cows culled, voluntary and involuntary culling rate were 24.8% and 75.2 % respectively. Infertility and metabolic disorders were the most f...
متن کاملCirculating metabolic hormones in different metabolic states of high producing Holstein dairy cows
Background: Information regarding the metabolic hormones in different metabolic states of high producing dairy cows can aid high producing herds to manage and resolve the metabolic and production problems. Furthermore, it can be considered as a tool to evaluate metabolic status of dairy cows. Herd managers can also evaluate the energy input-output relationships by assessing the metabolic profil...
