چکیده مقاله :

Six hundred day old unsexed broiler chicks were used in a 35-day trial to compare the effects of soybean oil, palm oil and fish oil supplementation on the performance of broilers in terms of feed intake, weight gain and feed conversion. The chicks were randomly distributed following a completely randomized design in four 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, diet containing 3.0% soybean oil, 3.0% palm oil and 3.0% fish oil. Results indicated thatsupplementation of different types of oil did not affect (P>0.05) feed intake of broilers up to 2nd week except increased (P<0.05) at 3rd, 4th and 5th weeks. Live weight gain of broilers did not differ (P>0.05) among groups up to 3rd week of age except at 4th week. The highest live weight gain at 4th week was found in 3.0% fish oil supplemented group. The palm oil group showed the least feed conversion value that differed only from fish oil group. Feed cost per broiler receiving fish oil was higher than that of without oil, palm oil and soybean oil groups. Total cost per broiler also differed (P<0.01) among the groups. Net profit expressed in US$ per kg live weight of broilers did not differ (P>0.05) between treatments. Maximum net profit was obtained from birds fed diet containing palm oil and minimum from broilers fed diet containing soybean oil. It was concluded that supplementation of fish oil at 3.0% level gave slightly higher live weight gain and feed conversion than those of the same level of soybean and palm oil. However, net profit as well as price per kg live broiler was comparatively higher in palm oil supplementation than in soybean oil and fish oil.

چکیده انگلیسی:

600 جوجه گوشتی تعیین جنسیت نشده یک روزه در یک آزمایش 35 روزه برای مقایسه اثرات روغن سویا، روغن نخل و روغن ماهی بر عملکرد جوجه‌های گوشتی شامل مصرف خوراک، افزایش وزن و ضریب تبدیل غذایی استفاده شد. جوجه‌ها به طور تصادفی در قالب طرح کاملاً تصادفی در چهار گروه با سه تکرار در هر تیمار توزیع شدند. در هر تیمار 150 و در هر تکرار 50 پرنده قرار داده شدند. چهار جیره غذایی با استفاده از مواد خوراکی در دسترس فرموله شد که شامل جیره غذایی بدون روغن، جیره غذایی حاوی 3/0 درصد روغن سویا، 3/0 درصد روغن نخل و 3/0 درصد روغن ماهی بودند. نتایج نشان داد که افزودن انواع مختلف روغن بر مصرف خوراک جوجه‌های گوشتی تا هفته 2 تأثیر نمی‌گذارد (05/0P>) اما در 3، 4 و 5 هفته افزایش می‌یابد (05/0P<). افزایش وزن زنده جوجه در میان گروه‌ها تا سن 3 هفته متفاوت نبود (05/0P>) البته در هفته 4 تفاوت داشت. بالاترین افزایش وزن زنده در هفته 4 در 3/0 درصد روغن ماهی گروه مشاهده شد. گروه روغن نخل حداقل تبدیل غذایی را نشان داد که فقط از گروه روغن ماهی متفاوت بود. هزینه خوراک در جوجه‌های گوشتی که روغن ماهی دریافت نمودند بیشتر از گروه بدون روغن، روغن نخل و روغن سویا بود. کل هزینه برای جوجه‌های گوشتی نیز در میان گروه‌های متفاوت بود (01/0P<). سود خالص بیان شده به دلار به ازای هر کیلوگرم وزن زنده جوجه بین تیمارها متفاوت نبود (05/0P>). حداکثر سود خالص از پرندگان تغذیه شده با جیره غذایی حاوی روغن نخل و حداقل از جوجه‌های گوشتی تغذیه شده با جیره غذایی حاوی روغن سویا بدست آمد. نتیجه‌گیری می‌شود که افزودن روغن ماهی در سطح 3/0 درصد سبب افزایش کمی در وزن زنده و خوراک تبدیل بیش از گروهی که از همان سطح از روغن سویا و نخل دریافت نمودند، می‌شود. با این حال، سود خالص و همچنین قیمت هر کیلوگرم گوشت مرغ زنده در مکمل روغن نخل نسبتاً بالاتر از روغن سویا و روغن ماهی بود.
