چکیده مقاله :
Two hundred and forty Hubbard Classic broiler chicks were used in a 35 day trial at Chittagong Veterinary and Animal Science University farm, Bangladesh to study the effects of supplemental choline chloride on performance parameters, carcass characteristics and their association in commercial broiler. All birds had free access to ad libitum feeding. Birds were fed four types of diet i.e. diet without choline chloride (T0), diet containing 0.1 g / 100 g choline chloride (T1), 0.2 g / 100 g choline chloride (T2) and 0.3 g / 100 g choline chloride (T3). Results indicated that weight gain differed (P<0.05) at 5th week irrespective of the level of supplemental choline. Similar to weight gain, feed intake also differed (P<0.05) at 5th week. However, feed conversion ratio differed from the 3rd to the 5th weeks. Weight gain and feed intake were positively correlated and feed conversion ratio was negatively correlated with carcass parameters. It could therefore be inferred that increasing levels of supplemental choline may progressively improve weight gain, feed efficiency and carcass characteristics in commercial broiler.
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.
