چکیده مقاله :
Six hundred day old unsexed broiler chicks were used in a 42-d trial at Chittagong Veterinary and Animal Sciences University Poultry Farm to find out the effects of different oils on productive performance of broilers. The chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. Each treatment had 150 birds, with 50 birds per replicate. Four diets were formulated using locally available ingredients as diet without oil, or diets containing 2.5% soybean oil, 2.5% palm oil and 2.5% fish oil. Results indicated that supplementation of diets with different types of oil significantly (P<0.05) improved live weight gain and feed consumption of broilers from the 3rd to the 5th wk. However, supplementation caused no significant (P>0.05) impact on feed conversion of broilers during 1-5 wk. Feed conversion improved (P<0.05) only during the 6th wk. Out of all carcass parameters, only feather weight, dressed weight, digestive tract weight and head weight differed (P<0.05) at the 4th wk. The survivability of broilers fed different types of oil was similar. It could, therefore, be inferred that the inclusion of soybean oil, palm oil and fish oil had a positive impact on weight gain, feed consumption and feed conversion in commercial broilers.
600 قطعه جوجه گوشتی تعیین جنسیت نشده در یک آزمایش 42 روزه در مرغداری دانشگاه علوم دامی و دامپزشکی چیتاگنگ مورد استفاده قرار گرفتند تا اثرات روغن‌های مختلف بر عملکرد تولیدی جوجه‌های گوشتی بررسی شود. جوجه‌ها به طور تصادفی در قالب یک طرح کاملاً تصادفی با چهار گروه تیماری و سه تکرار در هر تیمار توزیع شدند. هر تکرار شامل 50 پرنده بود. چهار نوع جیره غذایی با استفاده از مواد خوراکی که به صورت محلی در دسترس بودند فرموله شدند. تیمارها شامل جیره بدون روغن، جیره‌های حاوی 5/2 درصد روغن سویا، 5/2 درصد روغن خرما و 5/2 درصد روغن ماهی بودند. نتایج نشان داد که مکمل‌سازی جیره‌ها با انواع مختلف روغن به طور معنی‌داری (05/0>P) افزایش وزن زنده و مصرف خوراک جوجه‌های گوشتی را از هفته سوم تا پنجم بهبود داد. در هر حال، مکمل‌سازی سبب اثر معنی‌دار بر ضریب تبدیل خوراک در طی هفته‌های اول تا پنجم نشد (05/0<P). ضریب تبدیل خوراک فقط در طی هفته ششم بهبود یافت (05/0>P). در میان تمامی پارامترهای لاشه، فقط وزن پر، وزن لاشه، وزن دستگاه گوارش و وزن سر در هفته چهارم متفاوت بود (05/0>P). قابلیت زنده‌مانی جوجه‌های گوشتی تغذیه شده با انواع مختلف روغن مشابه بود. بنابراین، می‌توان استنباط کرد که استفاده از روغن سویا، روغن خرما و روغن ماهی در جیره دارای اثر مثبت بر افزایش وزن، مصرف خوراک و ضریب تبدیل خوراک در جوجه‌های گوشتی تجاری است.
