چکیده مقاله :

پیش بینی رخداد بیماریهای تولید و متابولیک در گاوداری های شیری با پایش اجزا معینی از خون و بررسی سیمای متابولیک امکانپذیراست. هدف از مطالعه حاضر، بررسی سیمای متابولیک در تعدادی از گاوداری های شیری شهرستان سنندج با ارزیابی پارامترهای بیوشیمیایی و هماتولوژیک می باشد. از 4 گله گاو شیری درگروههای کم تولید، متوسط تولید و پر تولید (هرگروه 7 رأس)به صورت تصادفی در دو فصل تابستان و زمستان از ورید دمی خونگیری بعمل آمد، عناصر خونی مورد ارزیابی شامل: گلوکز، کلسیم، فسفر غیرآلی، آنزیم‌های (Aspartate aminotransferase)ASTو CPK(Creatine phosphokinase) و هماتوکریت بودند. نتایج حاصل از این مطالعه نشان داد گلوکز و آنزیم AST در محدوده طبیعی بوده، در حالی که غلظت کلسیم کمتر ازمحدوده طبیعی و فسفر غیرآلی و آنزیم CPK مقادیر بیش از حد طبیعی را نشان دادند.اثر فصل بر میزان گلوکز، فسفر غیرآلی، آنزیم AST و هماتوکریت معنی‌دار بوده (05/0> P) اما ارتباط معنی داری با فعالیت آنزیم CPK و کلسیم نشان نداد (05/0 < P). بین میزان تولید شیر و آنزیم AST و هماتوکریت ارتباط معنی داری بدست آمد.(05/0 > P) درحالی که این ارتباط برای سایر پارامترهای خونی اندازه گیری شده مشهود نبود. (05/0 < P). یافته های حاصل از این مطالعه حضور برخی از بیماری های متابولیک حداقل در شکل تحت بالینی را (هیپوکلسمی و...) در منطقه و همچنین تأثیر برخی متغییرهای محیطی را نشان می دهد، که می تواند تأییدی بر انجام آزمایش سیمای متابولیک به صورت منظم و مستمر درگاوداری های منطقه البته در سطح وسیع تر باشد.

چکیده انگلیسی:

Metabolic profile tests are considered useful to predict the occurrence of production and metabolic diseases in dairy herds by monitoring certain components of the blood. The aim of this study was to investigate metabolic profile by means of determining the hematologic and biochemical parameters in some dairy herd in Sanandaj area. The blood samples were collected randomly from coccygeal vein in 4 dairy farms from 3 predefined groups of animal, i.e. peak lactation, mid lactation and low lactation (7 samples in each group) in two seasons of summer and winter. The following metabolites and enzymes were measured on blood samples: Glucose, calcium, inorganic phosphorus, aspartate aminotransferase, creatine phosphokinase and hematocrit. Results showed that the concentration of serum glucose and AST were in normal level, whereas results were showed elevated level of inorganic phosphorus and CPK, but decreased level of calcium. In addition the results showed significant differences between the glucose concentration, inorganic phosphorus, AST and hematocrit with season. (p≤0.05),while no significant difference was noticed between calcium concentration and CPK with season. (p>0.05). There were significant differences between milk yield and AST, hematocrit. (p≤0.05), but differences between the other metabolites and milk yield were not statistically significant (p>0.05). The results of this study indicated the presence of a number of metabolic diseases at least in subclinical forms, in this area (i.e. hypocalcaemia…) and concluded the influence of environmental factors on metabolic profiles. So the results confirmed to perform metabolic profile test continuously in this area, however, in further large scales.
