| این آزمایش با هدف بررسی اثر منبع دانه غلات (جو و ذرت) و اندازه ذرات علوفه یونجه (پودر شده در مقابل متوسط) بر عملکرد رشد، فراسنجههای خونی و تخمیر شکمبهای گوسالههای شیری انجام شد. از 32 رأس گوساله هلشتاین سه روزه (وزن اولیه 0/2 ± 4/36 کیلوگرم) در قالب طرح کاملاً تصادفی و آرایش فاکتوریل 2 × 2 استفاده شد. جیرههای آزمایشی شامل جیره حاوی دانه جو و علوفه یونجه پودر شده، دانه جو و علوفه یونجه با اندازه متوسط، دانه ذرت و علوفه یونجه پودر شده و دانه ذرت و علوفه یونجه با اندازه متوسط بودند. مصرف خوراک آغازین در گوسالههای تغذیه شده با جیرههای حاوی دانه ذرت در مقایسه با دانه جو در دوره قبل و بعد از شیرگیری و کل دوره بالاتر بود. گوسالههای تغذیه شده با جیره حاوی دانه ذرت دارای وزن نهایی و میانگین افزایش وزن روزانه بالاتری در مقایسه با دانه جو بودند. اندازه ذرات علوفه یونجه تاثیری بر مصرف خوراک آغازین و میانگین افزایش وزن روزانه نداشت. ارتفاع هیپ و جدوگاه گوسالههای تغذیه شده با جیره حاوی دانه ذرت در مقایسه با دانه جو بالاتر بود. در گوسالههای تغذیه شده با جیره حاوی دانه ذرت در مقایسه با دانه جو غلظت کل اسیدهای چرب فرار افزایش و نسبت مولی استات کاهش یافت. در این مطالعه تقابلی بین منبع غلات خوراک آغازین و اندازه ذرات علوفه بر عملکرد گوسالههای شیری مشاهده نشد اما استفاده از دانه ذرت در خوراک آغازین عملکرد گوسالههای هلشتاین طی دوره انتقال از خوراک مایع به جامد را بهبود داد. | ||

| چکیده [English] | ||
| This study was conducted to investigate the effect of grain sources (corn or barley) and alfalfa hay particle size (PS; fine or medium) on growth performance, blood parameters and ruminal fermentation of dairy calves. Thirty-two 3-d-old Holstein dairy calves (36.4 ± 2.0 kg of body weight) were used in a completely randomized design with 2 × 2 factorial arrangement. Experimental diets consisted of diet containing barley grain with fine alfalfa hay PS, barley grain with medium alfalfa hay PS, corn grain with fine alfalfa hay PS and corn grain with medium alfalfa hay PS. Starter feed intake was greater for calves fed corn than those fed barley during the pre- and post-weaning and overall periods. Calves fed corn had greater final body weight as well as overall average daily gain (ADG) than barley calves. However, alfalfa hay PS had no effect on starter intake and ADG. Hip and wither heights were greater in calves fed corn than those fed barley. Total volatile fatty acids concentrations increased and the molar proportion of acetate decreased in calves fed corn compared to those fed barley. These results showed no interactions between grain sources and alfalfa hay PS on calf performance; however, corn inclusion in starter diet improved the growth performance of Holstein calves during the transition from liquid to solid feed. | ||
