چکیده

اثر استفاده از دانه کامل گلرنگ و کتان در دوره پیرامون زایش بر عملکرد، ضرایب هضمی، تولید و ترکیب آغوز و فراسنجه­های خونی میش­های افشاری با سه تیمار و استفاده از 27 رأس میش آبستن با میانگین سن سه سال، وزن 1/28±85 کیلوگرم و محدوده شش هفته پیش از زمان زایش موردانتظار، در قالب طرح کاملاً تصادفی بررسی شد. تیمارهای آزمایشی شامل 1- جیره شاهد (پایه)، 2- جیره حاوی هشت درصد دانه گلرنگ، 3- جیره حاوی هشت درصد دانه کتان بودند. اثر تیمارهای آزمایشی بر صفات عملکردی میش­ها پیش از زایش معنی‌دار نبود ولی ماده­خشک مصرفی و تغییرات وزن میش‌ها پس از زایش، تحت تأثیر تیمارهای گلرنگ و کتان قرار گرفتند (0/05>P). اثر تیمارهای آزمایشی بر ضرایب قابلیت هضم مواد مغذی در پیش از زایش، میزان و ترکیب آغوز و شیر تولیدی میش­ها و نیز عملکرد بره­ها معنی­دار نبود. میزان تری‌گلیسرید، کلسترول و لیپوپروتئین با دانسیته بالا پلاسمای خون میش­هایی که با کتان تغذیه شدند بیش‌تر از تیمارهای گلرنگ و شاهد در پیش از زایش بود (0/05>P). یافته‌های این آزمایش نشان داد که استفاده از دانه­های روغنی گلرنگ و کتان در دوره نزدیک به زایش اثرات منفی بر عملکرد میش­های آبستن ندارد ولی مصرف ماده خشک را پس از زایش افزایش داده و با جلوگیری از افت شدید وزن آن‌ها پس از زایش، سلامتی میش­های شیرده و بره­ها را بهبود می‌بخشند.

چکیده [English]

The effect of using whole safflower seed and flaxseed in the during transition period on performance, digestibility, production and composition of colostrum and blood parameters of Afshari ewes using three treatments and 27 pregnant ewes with average age of  three years, weight of 85 ± 1.28 kg and range 6 weeks before expected lambing in a completely randomized design was investigated. Experimental treatments included; 1- control diet (base), 2- diet containing 8% safflower seed, 3- diet containing 8% flaxseed. The effect of treatments was not significant on functional traits of ewes pre-lambing but their dry matter intake and weight change post lambing were affected by safflower seed and flaxseed treatment (P< 0.05). The experimental treatments were not significant on pre-lambing digestibility coefficients, composition and amount of colostrum and milk as well as lamb performance. The triglyceride, cholesterol and high-density lipoprotein levels in blood plasma of flaxseed-fed ewes were higher than safflower and control treatments in pre-lambing. The results demonstrated that using safflower seed and flaxseed in the period close to  lambing did not have negative effects on the performance of gestation ewes but increased their dry matter and improved the health of lactating ewes and lambs by preventing severe weight loss in post lambing.
