| هدف از پژوهش کنونی برآورد وراثتپذیریها، همبستگیهای ژنتیکی، فنوتیپی و محیطی و نیز شناسایی عوامل خطر مرتبط با بروز جفتماندگی و متریت در سه زایش نخست گاوهای هلشتاین بود. در این پژوهش از دادههای گاو شیری نژاد هلشتاین استفاده شد که طی سالهای 1387 تا 1396 در 17 گله بزرگ جمعآوری شده بودند. دادهها در شکمهای اول، دوم و سوم زایش به ترتیب مربوط به 63039، 46265 و 30031 رأس گاو بودند. برای ارزیابی ژنتیکی از تجزیه و تحلیل چند صفتی تحت مدل آستانهای استفاده شد. برای شناسایی عوامل خطر مرتبط با بروز متریت و جفتماندگی از مدل رگرسیون لجستیک چند متغیّره استفاده شد. در بین عوامل خطر بررسی شده مرتبط با بروز جفتماندگی و متریت، به ترتیب مردهزایی و جفتماندگی بیشترین تأثیر را بر بروز این بیماریها داشتند. میانگینهای پسین وراثتپذیری جفتماندگی در زایش اول، دوم و سوم به ترتیب 0.06، 0.03 و 0.05 و متریت به ترتیب 0.03، 0.2 و 0.03 به دست آمدند. میانگینهای پسین همبستگی ژنتیکی بین زایشهای مختلف برای جفتماندگی (0.41 تا 0.73) و متریت (0.34 تا 0.9) متوسط رو به بالا به دست آمدند. با توجه به همبستگیهای ژنتیکی و فنوتیپی کمتر از واحد بین جفتماندگی و نیز بین متریت در سه زایش نخست، میتوان نتیجه گرفت که متریت و جفت ماندگی در این زایشهای گاوهای هلشتاین ایران صفات مختلفی هستند و هنگام ارزیابی ژنتیکی این صفات در گاوهای هلشتاین ایران اطلاعات هر شکم زایش باید به عنوان صفات مجزائی در نظر گرفته شوند. | ||

| Abstract The objectives of this study were to estimate heritability and genetic, environmental and phenotypic correlations between retained placenta (RP) and metritis (MET) and also identification of risk factors associated with these traits in the first three parities of Iranian Holsteins. In the present investigation, data on RP and MET in Holstein dairy cows which were collected from 2008 to 2017 in 17 large dairy herds were used. Data across the first, second and third parties included records on 63039, 46265 and 30031 cows, respectively. A multivariate analysis under threshold models was considered for genetics evaluation. Multivariate Logistic regression models were used to identify the risk factors associated with MET and RP. The most important risk factor associated with RP and MET were stillbirth and Retained Placenta, respectively. Posterior means for heritability of RP were 0.06, 0.03, and 0.05 and those of MET were 0.03, 0.2, and 0.03 in the first, second, and third parity, respectively. Posterior means of genetic correlations across parities were moderate to high for RP (0.41-0.73) and MET (0.34-0.9). Genetic and phenotypic correlations between RP and / or between MET across the parities were lower than unity which implying RP and/or MET may be considered as distinct traits in different parities which is required to be considered in genetic evaluation of these traits in the Iranian Holstein cows. | ||
