[ 1 ] - Alterations of the electrocardiographic parameters in relation to circulating electrolytes and cardiac enzymes during different productive states of high producing Holstein dairy cows
BACKGROUND: Dairy cows undergo physiological changes during pregnancy and lactation and cardiovascular system may alter during these periods. OBJECTIVES: Understanding the physiological effects of production periods of dairy cows on heart electrical activities can aid to better monitoring the cardiovascular system in these animals. METHODS: Five multiparous Holstein dairy cows were studied from...
[ 2 ] - Thyroid hormones profile in Holstein calves following dexamethasone and isoflupredone administration
BACKGROUND: Glucocorticoids are the steroidal drugs which are very widely used in large animal medicine. These agents have advantages in large animals but they have been also associated with many potential adverse effects especially at high doses or prolonged use. OBJECTIVES: The present experimental study was designed to clarify the effects of dexamethasone (DEXA) and isoflupredone (ISO), as t...
[ 3 ] - Circulating 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...
[ 4 ] - Oxidative stress and protein catabolism following dexamethasone and isoflupredone administration in Holstein calves
Background: Glucocorticoids have several benefits in large animal medicine but apart from their benefits, there are several disadvantages attributed to the use of these drugs. Among the disadvantages, disturbance in protein metabolism is one of the side effects of glucocorticoids which has been investigated in human and laboratory animals. OBJECTIVES: There are no information regarding the effe...
[ 5 ] - Study on serum glucose, insulin, NEFA, BHBA and lipid profile in different productive status of high producing Holstein dairy cows
Background: Metabolic profiles have been used in efforts to predict pre parturient problems and fertility, to diagnose metabolic diseases, and to assess nutritional status in dairy cows. These profiles may help to confirm the diagnosis of sub clinical diseases, to be aware of possible causes of infertility in the herds, or to monitor improvement in herd animals. OBJECTIVES: This study investiga...
[ 6 ] - The relationships among acute phase response proteins, cytokines, and enzymes during ovine experimental endotoxemia
BACKGROUND: The acute phase response is beneficial to theanimal in restoring homeostasis, and measuring the circulatingacute phase proteins, cytokines, and enzymes can be used toevaluate the innate immune system's responses to invader agentssuch as bacterial lipopolysaccharide. Measurement of theseparameters has shown to be useful as diagnostic and prognosticmarkers in animal endotoxemia. OBJEC...
[ 7 ] - Correlations among homocysteine, cardiac troponin I and cardiac enzymes in different ages of clinically healthy male dromedary camels
BACKGROUND: Information regarding serum biochemicalprofile can reflect cardiovascular performance in animals.Although studies have evaluated the inter-relationship amongcardiovascular biomarkers in animals and human beings, thereare no reports of such a probable relationship in camelids.OBJECTIVES: The aim of the present study was to provide dataon the correlations among cardiovascular biomarke...
[ 8 ] - Furosemide Induced Electrocardiographic Alterations in High Producing Holstein Dairy Cows
Diuretics have several therapeutic advantages in dairy cows but there are different side effects such as acid-base and electrolyte imbalances which may affect the electrocardiographic parameters. Fifteen multiparous, clinically healthy, non-pregnant and high producing 4-year-old Holstein dairy cows at their early lactation period were randomly divided into 3 equal experimental groups. Furosemid...
[ 9 ] - ارزیابی شاخصههای متابولیکی سرم اسبهای دره شوری و ارتباط آنها با یکدیگر
زمینه مطالعه: نژادهای مختلف اسب دارای پروفایل متابولیکی مختص به خود می‌باشند که اطلاعات مربوط به این پروفایل نشان دهنده وضعیت سلامت آن هاست. هدف: هدف از انجام پژوهش حاضر، معرفی پروفایل متابولیک اسبهای نژاد دره شوری و بررسی ارتباط آنها با یکدیگر است. روش کار: نمونه‌های خون از 56 راس اسب دره شوری (5 تا 7 ساله) شامل26 راس مادیان غیر باردار و غیر شیرده و 30 راس نریان اخذ شد و در سرم آنها گلوکز، ...
[ 10 ] - Insulin Resistance and its Relevance with Age, Sex, Season and Obesity in Darehshori Horse Breed
BACKGROUND: Equine metabolic syndrome is an endocrinopathy that affects different breeds of horses and ponies. This metabolic disorder is a multifactorial syndrome and it is primarily linked to obesity, dyslipidemia and insulin resistance. OBJECTIVES: The present study was performed to evaluate insulin resistance in Darehshori horses with regards to age, sex, season and obesity. METHODS: Twelve...
[ 11 ] - The comparative clinical efficacy of intravenous insulin regular, dexamethasone and flunixin meglumine on ovine experimental endotoxemia
The lack of an effective treatment for endotoxemia causes high mortality rates in affected animals. Forty clinically healthy 1-year old Iranian fat-tailed ewes were assigned randomly into 8 experimental equal (n = 5) groups, comprising Insln 1.5, Insln 3, Insln 6, Insln 9, Insln 20, Dexa, Flnx and Control. Lipopolysaccharide from E. coli serotype O55:B5 was used to induce endot...
[ 12 ] - Seasonal Variation and Relationships Between Copper of Serum and Various Tissues in Copper Poisoned Sheep in Kerman Province, Iran
Background: Soil and plant contamination in copper exposure causes chronic copper poisoning (CCP) in animals following the consumption of plants in these soils. Objectives: The present study was carried out on 10 clinically affected copper poisoned cases (in each season) from autumn 2015 to the end of summer 2016, in four seasons in Kerman province to evaluate the seasonal effects of CCP in she...
[ 13 ] - Circulating metabolic biomarkers and hormones and their relationships at different pre- and post-parturition periods of Ghezel ewes
Information regarding metabolic profile in different physiological periods of ewes can assist veterinarians to monitor the herd health and productive performance. Furthermore, the relationships among the metabolic parameters can be used to detect the effect of each parameter on another one. Five clinically healthy adult Ghezel ewes were selected at 4 weeks before parturition and evaluated at 4 ...
[ 14 ] - Seasonal variations of tissues and serum copper concentrations in chronic copper poisoned goats
Primary chronic forms of copper poisoning have been reported to occur in goats around the copper industries in Kerman province. The survey was carried out from autumn 2015 to the end of summer 2016, in Kerman province, Iran. Based on clinical signs, confirmed by necropsy and copper concentration of serum and different tissues, ten live chronic copper poisoned (CCP) goats were used in the study ...
