چکیده مقاله :

این تحقیق به منظور مطالعه تاثیر افزودن اسیدآمینه تائورین بر عملکرد، خصوصیات لاشه، فاکتورهای خونی و آنزیم‌های کبدی در جوجه گوشتی انجام شد. آزمایش در 45 روز در قالب طرح کاملا تصادفی با تعداد 300 قطعه جوجه گوشتی یک روزه سویه راس، شامل 4 تیمار، 5 تکرار و 15 قطعه پرنده در هر تکرار با جیره¬های هم¬انرژی و هم¬پروتئین با شرایط پرورشی یکسان صورت گرفت. تیمارهای آزمایشی شامل: تیمار اول (جیره پایه) و به ترتیب تیمار دوم، سوم و چهارم: جیره پایه همراه با 1 گرم در کیلوگرم اسیدآمینه تائورین،3 گرم در کیلوگرم اسیدآمینه تائورین و 6 گرم در کیلوگرم اسیدآمینه تائورین بود. نتایج نشان داد در طول دوره پرورش افزایش وزن بدن، مصرف خوراک و ضریب تبدیل غذایی، در بین تیمارهای آزمایشی با تیمار شاهد معنی¬دار بود (05/0p ). اما از لحاظ عددی عملکرد بهتری با اضافه شدن مکمل تائورین به جیره در این آنزیم‌ها مشاهده شد. به طور کلی نتایج این آزمایش نشان داد اضافه کردن 6 گرم در کیلوگرم اسیدآمینه تائورین بدون تاثیر منفی بر عملکرد و خصوصیات لاشه، منجر به بهبود در تیتر فراسنجه¬های خونی و آنزیم‌های کبدی می¬شود.

چکیده انگلیسی:

This research was conducted in order to study the effect of taurine amino acid addition on performance, carcass characteristics, blood factors and liver enzymes in broilers. The experiment was conducted in 45 days in the form of a completely random design with 300 pieces of one-day-old broilers of the Ras strain, including 4 treatments, 5 repetitions and 15 birds in each repetition with the same energy and protein diets with the same rearing conditions. The experimental treatments included: the first treatment (basic diet) and the second, third and fourth treatments respectively: the basic diet along with 1 g/kg taurine amino acid, 3 g/kg taurine amino acid and 6 g/kg taurine amino acid. The results showed that body weight gain, feed consumption and food conversion ratio were significant between the experimental treatments and the control treatment during the breeding period (P0.05). But numerically, a better performance was observed with the addition of taurine supplement to the diet in these enzymes. (P > 0.05). In general, the results of this experiment showed that adding 6 grams/kg of taurine amino acid leads to an improvement in the titer of blood parameters and liver enzymes without negatively affecting the performance and characteristics of the carcass.
