From;    Author:Stand originally


Ration adds fish oil to be able to alleviate the bowel that chicken brings about because of ball bug disease is damaged (Allen, 1996; Allen, 1998) . Add 0.5 % , 1 % and the corn oil of 2 % respectively in the chicken ration that does not contain any remedy (contain a lot ofN-6 PUFA) with fish oil, mix with LPS respectively IBV immunity chicken, the cell in system of change of weightening finish of day of each groups of chicken, temperature and haemal circulation is vivid element of element, leucocyte interpose 1, hepatic excretive is urgent photograph albumen (Acute Phase Protein) (blood coagulates enzymatic with Jin Su sulfur because albumen) drip with the antibody that fights IBV spend wait for index difference all, among them the each photograph index of chicken of group of 2 % fish oil relatively the tendency that other group has improvement (Korver, 1997; Korver 1998) . Fritcher (1991) in corn of 1 day age hen - the beans dregses of rice model same amount is added respectively in fundamental ration (7 % ) oil of fish oil of flax seed oil, herring, lardy, corn and double low rape oil, raise feeds a hen 3 weeks, with SRBC immunity chicken, determined to accompany A of sword bean globulin into the law with 3H- adenosine mix into (Con A) , business land closes to segmentation element (PWM) the lienal cell that causes with LPS stimulation is proliferous. As a result discovery is collected feed the antibody drop that SRBC resists inside the chicken substance that contains feed of fish oil of 7 % herring to spend extremely remarkable (P<0.005) prep above is other each groups; Lienal cell of flax seed oil and chicken of fish oil group because Con A and the proliferous effect that PWM stimulation produces part than other group low 30 % (P<0.13) with 50 % (P<0.05) ; Each groups of stimulative to LPS proliferous effect are not apparent.

3. Fish oil tastes qualitative influence to rasorial body and birds egg

Already was clear about now, the sort of ration fatty acid and amount are deciding rasorial body organization and birds egg fatty acid directly make a kind. Current, rasorial ration adds the main purpose of fish oil to depend on passing the content of the EPA in raising birds flesh and birds egg and DHA, in order to satisfy human health the demand to N-3 PUFA. Had not seen concerned research N-3 PUFA is in at present the data of respect of efficiency of animal airframe deposit.

3. 1 fryer ration adds fish oil to be able to raise body to organize the deposit of pair of N-3 PUFA

The type of not saturated fatty acid and content can change ration quickly to grow quickly of the fatty acid in gallinaceous organization form (Watkins, 1989) . Ration adds seed of herring fish oil, flax respectively oil of oily, soybean oil, corn, safflower oil, birds oil, lardy after with bovine oil raise feeds a fryer for some time, other of remarkable prep above of the EPA in collecting the chicken system that feeds feed of the fish oil that contain herring to organize and DHA each groups, body of chicken of flax seed oily group organizes medium EPA and DHA content take second place; The N in organization of body of chicken of soybean oil group - 6 model PUFA content is highest; And content of saturated fatty acid is highest in collecting the chicken system that feeds animal oily feed to organize (Phetteplace, 1992; Di Jile, 1994; López-Ferrer, 1999) . Hargis (1991) , Phetteplace and Watkins(1989) report, n-3 PUFA, especially the N-3 in fish oil PUFA (especially EPA and DHA) the content of the N-6 in bursa of family name of muscle, hepatic to reducing chicken, law and thymus PUFA and cock blood are extremely medium low density lipoprotein (VLDL) synthesis is particularly effective.
