Abstract :

به منظور بررسی اثر مکمل کولین کلرید بر پارامترهای عملکردی، خصوصیات لاشه و ارتباط آن‌ها در جوجه‌های گوشتی تجاری، 240 جوجه گوشتی هوبارد کلاسیک در آزمایشی 35 روزه، در مزرعه دانشگاه دامپزشکی و علوم دامی چیتاگونگ بنگلادش آزمایش شدند. تمام پرندگان در حد اشتها، به خوراک دسترسی آزاد داشتند. پرندگان از چهار نوع از رژیم غذایی، بدون کولین کلراید (T0)، جیره غذایی حاوی 1/0 گرم / 100 گرم کولین کلراید (1T)، 2/0 گرم / 100 گرم کولین کلراید (2T) و 3/0 گرم / 100 گرم کولین کلراید (3T) تغذیه شدند. نتایج نشان داد که صرف نظر از سطح مکمل کولین، افزایش وزن در هفته 5 متفاوت است (05/0P<). مشابه به افزایش وزن، خوراک مصرفی در هفته 5 متفاوت بود (05/0P<). با این حال، ضریب تبدیل غذایی از 3 به 5 هفته تفاوت داشت. رابطه افزایش وزن و مصرف خوراک مثبت بود و ضریب تبدیل غذایی با پارامترهای لاشه همبستگی منفی داشت. بنابراین می‌توان نتیجه گرفت که افزایش سطح مکمل کولین ممکن است سبب بهبود افزایش وزن، بازده خوراک و خصوصیات لاشه در جوجه‌های گوشتی تجاری شود.
