چکیده

این مطالعه به ­­منظور بررسی اثرات منابع مختلف چربی بر عملکرد تولیدی، سیستم ایمنی و میکروفلورای دستگاه گوارش در مرغ­ های تخم ­گذار تجاری انجام شد. در این مطالعه، 140 قطعه مرغ تخم ­گذار تجاری سویه ال اس ال با سنن 35 هفتگی ، در 7 گروه با 5 تکرار برای 12 هفته مورد استفاده قرار گرفتند. عملکرد تولیدی، ایمنی هومورال و میکروفلورای روده بررسی شدند. نتایج نشان داد که سطوح مختلف منابع چربی به شکل معنی  داری تولید تخم­ مرغ و توده تخم ­مرغ را افزایش داد ولی میزان ضریب تبدیل خوراک مصرفی را کاهش داد (0/05>p ). سطوح مختلف منابع چربی توانست به شکل معنی­ داری پاسخ ­های ایمنی را در مرغ ­های تخم ­گذار افزایش دهد. تیتر آنتی ­بادی در پاسخ به SRBC در 28 روزگی در گروه ­های اسیدچرب سویا و روغن کیلکا در مقایسه با گروه روغن سویا و شاهد بیش ­تر بود (0/05>p ). نتایج هم ­چنین نشان داد که افزودن سطوح مختلف روغن ­های مختلف به جیره، جمعیت سالمونلا، اشرشیای کولای و کولی فرم ­ها را به شکل معنی ­داری در مقایسه با گروه شاهد کاهش داد (0/05>p ). در مجموع می­ توان بیان نمود که منابع مختلف چربی خصوصاً روغن ماهی می ­توانند پاسخ ­های ایمنی، عملکرد و جمعیت میکروبی روده را در مرغ­ های تخم ­گذار بهبود بخشد.

چکیده [English]

 This study was conducted to investigate the effects of different fat sources on production performance, immune system and intestinal microflora in commercial laying hens. In this study 140 laying hens in 7 groups, with 5 replications for 12 weeks were used studied. Production performance, humoral immunity and intestinal microflora population were investigated. The results showed that different levels of fat sources increased significantly egg production and egg mass but decreased feed conversion ratio(p < 0.05). Different levels of fat sources were able to significantly increase immune responses in laying hens. Antibody titers in response to SRBC at 28 days were higher in soybean oil and kilka oil groups than in soybean oil and control groups (p < 0.05). The result also showed that adding different sources of fat to the diet reduce population salmonella, E. coli and Coliform compared to the control group (p < 0.05). Overall, it can be stated that different fat sources, especially fish oil, can improve the immune responses, performance and microbial population of the intestine in laying hens.
