چکیده
هدف این پژوهش، بررسی اثر جایگزینی الیاف سلولزی (کاه گندم) با الیاف غیر سلولزی (تفاله چغندرقند) در جیره گاوهای شیری دوره انتقال (از روز 21 پیش از زایش و تا روز 42 پس از زایش) بود. بدین منظور، 21 روز پیش از زایش، از 36 راس گاو هلشتاین چند شکم زایش با میانگین وزن 59/6±697 کیلوگرم و نمره بدنی 0/22±3/3 استفاده شد. پیش از زایش، گاوها به دو گروه تقسیم شدند و جیره‌های دارای 7/17 درصد کاه گندم و یا 7/17 درصد تفاله چغندرقند، دریافت کردند. پس از زایش نیز هر گروه به دو زیرگروه تقسیم شد و جیره‌ای بر پایه 5 درصد کاه گندم یا تفاله چغندرقند دریافت کردند. نتایج نشان دادند که تفاوت در منبع الیافی جیره، تأثیری بر مصرف خوراک در دوره پیش از زایش نداشت، ولی گوارش‏پذیری ماده خشک و ماده آلی و دیوارۀ سلولی در گاوهایی که جیره دارای تفاله چغندرقند مصرف کرده بودند، بیش‌تر بود. گوارش‏پذیری ماده خشک (p=0/06) و دیواره سلولی (p=0/06) در گاوهایی کم‌تر بود که در دوره‌های پیش از زایش و نیز پس از زایش، کاه گندم مصرف کرده بودند. شیر تصحیح‌شده بر پایۀ چربی و انرژی و هم‌چنین درصد چربی شیر در گاوهایی که پیش از زایش تفاله چغندرقند دریافت کردند، تمایل به افزایش داشت (p=0/09). نتایج این پژوهش نشان داد که تغذیه منابع الیافی غیرسلولزی، می‏تواند عملکرد گاوهای دوره انتقال را بهبود بخشد.

چکیده English

This study was conducted to compare the effect of a cellulosic (wheat straw; WS) and non-cellulosic (beet pulp; BP) forage source on high producing dairy cows during the transition period (three weeks before to six weeks after calving). Multiparous Holstein cows (n=36) with mean body weight of 697±59.6 kg and body condition score of 3.3±0.22 were used in the experiment. Before calving, the cows received diets containing 7.17% WS (n=18) or BP (n=18). After calving, the cows in each group were divided into two subgroups (n=9), and received the diets containing 5% BP or WS. Prepartum dry matter intake (DMI) was similar between dietary treatments but prepartum digestibility of DM (P=0.05) and neutral detergent fiber (P= 0.06) was lower in cows feeding on the WS diet. The yield of energy-corrected milk, 4% fat-corrected milk and milk fat percentage tended to be higher in the cows fed with the BP diet during the prepartum period (P = 0.09). In conclusion, the results showed that feeding non-cellulosic forages during the transition period may improve the performance in dairy cows.
