چکیده مقاله :
This study was conducted to investigate the effect of dairy cow diets containing different protein sources [soybean meal, xylose protected soybean meal (Yasminomax®), and steam-flaked whole soybean] and various partially processed grain on in vitro gas production kinetics and the microbial nitrogen yield. Soybean meal (S) and xylose protected of soybean meal (XS) were provided as 0.56:0.44 (SXSL) and 0.51:0.49 (SXSH) ratios. The diets were ground barley (B) + S, B+ SXSL, steam-flaked barley (FB) + S, FB + SXSL, B + steam-flaked whole soybean (WS), B + SXSH, FB + WS and FB + SXSH. An in vitro gas production technique was used to define the differences in the microbial nitrogen production of the diets. Asymptotic gas volume (b) was higher than the others for diets containing steam-flaked whole soybean (P<0.01). The highest constant rate of gas production (c) belongs to diet with ground barley and soybean meal, the highest halftime of gas production (t1/2) was obtained from diet with steam-flaked barley and soybean meal (P<0.01). The microbial nitrogen yield and consequently microbial nitrogen to diet nitrogen ratio were higher in diets containing xylose protected soybean meal than the others, especially, when compared with steam-flaked whole soybean diets (P<0.05). These results showed that WS, when compared with S and XS may not improve rumen fermentation and microbial nitrogen production with both ground and steam-flaked barley grain and the best performance in microbial nitrogen yield belongs to xylose protected soybean meal.
این مطالعه برای بررسی اثر جیره های گاو شیری با منابع مختلف پروتئینی [کنجاله سویا، کنجاله سویای محافظت شده با زایلوز (یاسمینومکس®)، و دانه سویای پولکی با بخار] و دانه جو با فراوری مختلف بر کنتیک تولید گاز و تولید نیتروژن میکروبی انجام شده است. جیره های آزمایشی شامل دانه جو آسیاب + کنجاله سویا، دانه جو آسیاب + کنجاله سویای محافظت شده با زایلوز (سطح کم)، دانه جو پولکی با بخار + کنجاله سویا، دانه جو پولکی با بخار + کنجاله سویای محافظت شده با زایلوز (سطح کم)، دانه جو آسیاب + دانه سویای پولکی با بخار، دانه جو آسیاب + کنجاله سویای محافظت شده با زایلوز (سطح زیاد)، دانه جو پولکی با بخار + دانه سویای پولکی با بخار و دانه جو پولکی با بخار + کنجاله سویای محافظت شده با زایلوز (سطح زیاد) بودند. روش تولید گاز در شرایط in vitro برای تعیین تفاوت های تولید نیتروژن میکروبی بین جیره ها استفاده گردید. پتانسیل تولید گاز (b) در جیره های دارای دانه سویای پولکی با بخار در مقایسه با سایر جیره ها، بیشتر بود (0.01>P). بالاترین نرخ ثابت تولید گاز (c) متعلق به جیره دارای دانه جو آسیاب و کنجاله سویا بود (0.01>P). بالاترین نیمه عمر تولید گاز (t2/1) نیز در جیره با دانه جو آسیاب و کنجاله سویا ثبت شد (0.01>P). تولید نیتروژن میکروبی و در نتیجه نسبت نیتروژن میکروبی به نیتروژن جیره در جیره های محتوی کنجاله سویای محافظت شده با زایلوز نسبت به جیره های دیگر و بویژه در مقایسه با جیره های دارای دانه سویای پولکی با بخار بالاتر بود (0.05>P). این نتایج نشان داد که دانه سویای پولکی با بخار در مقایسه با کنجاله سویا و کنجاله سویای محافظت شده با زایلوز، تخمیر شکمبه ای و تولید نیتروژن میکروبی را در ترکیب با دانه جو آسیاب و دانه جو پولکی با بخار ممکن است بهبود ندهد و بهترین نتایج در تولید نیتروژن میکروبی به کنجاله سویای محافظت شده با زایلوز مربوط بود.
