| هدف از پژوهش حاضر مقایسه تأثیر جیرههایی دارای مقادیر متفاوت دانه کتان بر عملکرد تولیدمثلی میشهای بلوچی سه الی چهار سالهی دارای فحلی همزمان شده در نزدیک زایمان بود. برهها بلافاصله پس از تولد از مادر جدا شدند و آزمایش تا 60 روز ادامه یافت. جیره های آزمایشی شامل: تیمار A: بدون دانه کتان، تیمار B: شامل 2 درصد دانه کتان، تیمارC : شامل 5 درصد دانه کتان، تیمار D: شامل 7 درصد دانه کتان، تیمار E: شامل 10 درصد دانه کتان، تیمار F: شامل 12 درصد دانه کتان. نتایج حاصل از این آزمایش نشان داد که مصرف ماده خشک در میشهایی که از جیره بدون دانه کتان تغذیه کردند کمتر بود(05/0>P ). بیشترین میانگین وزن بدن میشها درجیره بدون دانه کتان و کمترین مربوط به جیره با 5 درصد دانه کتان (2/55 کیلوگرم در مقابل 4/46 کیلوگرم) بود. نرخ فحلیابی تفاوتی بین جیرههای آزمایشی نداشت (05/0<P). درصد تخمکریزی، درصد آبستنی و درصد دوقلوزایی در جیرههای با 10 و 12 درصد دانه کتان بیشتر از سایر گروهها بود (05/0>P ). | ||
