Cov nyhuv ntawm LED yug me nyuam teeb rau nqaij thiab qe
LED yug me nyuam lub teeb muaj qhov pom kev zoo tshaj plaws rau cov nqaij qaib, thiab tuaj yeem paub qhov txawv ntawm qhov ci thiab xim ntawm lub teeb. Lub teeb LED, lub teeb pom kev zoo nrog ib lub wavelength, raug xaiv los teeb pom kev broilers thiab nteg hens los tshawb txog cov nyhuv ntawm lub teeb monochromatic ntawm kev loj hlob, kev loj hlob thiab kev ua tau zoo ntawm broilers thiab nteg hens.
Cov txiaj ntsig ntawm txoj kev tshawb fawb pom tau tias nyob rau theem pib ntawm kev loj hlob ntawm broilers, pawg teeb ntsuab tau nce qhov hnyav dua thiab muaj cov nqaij noj tsawg dua; Nyob rau theem tom ntej ntawm txoj kev loj hlob, cov pab pawg xiav lub teeb tau nce qhov hnyav, nrog qhov qis tshaj plaws pub rau cov nqaij sib piv, thiab qhov hnyav ntawm lub cev, lub mis hnyav, tus ncej puab, thiab qhov hnyav hnyav. Qhov Performance indexes thiab evisceration hnyav yog 14.39 feem pua -19.86 feem pua siab dua lwm pab pawg. Ntawd yog, piv nrog lub teeb liab thiab dawb, lub teeb ntsuab txhawb kev loj hlob ntawm broilers thaum ntxov ntawm kev loj hlob, thiab lub teeb xiav txhawb kev loj hlob ntawm broilers nyob rau theem tom ntej ntawm kev loj hlob. Nyob rau tib lub sijhawm, broilers tau irradiated nrog fluorescent teeb, thiab nws tau pom tias qhov hnyav nce ntawm broilers tsa nyob rau hauv lub teeb xiav-ntsuab yog ho siab dua li cov broilers tsa nyob rau hauv lub teeb liab thiab dawb.
Cov txiaj ntsig saum toj no tag nrho qhia tias lub teeb ci monochromatic cuam tshuam rau kev loj hlob thiab kev loj hlob ntawm qaib. Qhov sib txawv wavelengths ntawm lub teeb tuaj yeem cuam tshuam rau tus cwj pwm ntawm broilers, xws li qaug zog hauv broilers tsa nyob rau hauv lub teeb liab thiab dawb, thaum broilers tsa nyob rau hauv xiav thiab ntsuab lub teeb siv sij hawm ntau noj tsis tu ncua. Qhov no tej zaum yuav yog vim li cas vim li cas lub cev hnyav, cov leeg nqaij ntawm lub mis, qhov hnyav ntawm tus ncej puab, qhov hnyav ntawm qhov hnyav thiab qhov hnyav ntawm broilers tsa nyob rau hauv lub teeb xiav-ntsuab tau ntau dua li cov pab pawg liab thiab dawb.
Tus po yog lub cev tiv thaiv kab mob loj tshaj plaws ntawm cov tsiaj hauv lub cev, muaj ntau cov lymphocytes thiab macrophages, thiab yog qhov chaw nruab nrab ntawm lub cev tiv thaiv kab mob hauv lub cev thiab kev tiv thaiv humoral.
Thaum lub cev tiv thaiv kab mob tshwm sim, cov lymphatic sheath nyob ib puag ncig thickens; Thaum muaj kev tiv thaiv kab mob humoral, lymphoid nodules proliferate, thiab plasma hlwb thiab macrophages hauv splenic qaum nce ntau.
Yog li ntawd, HE histological staining thiab immunohistochemical staining tau siv los kawm txog cov kev hloov pauv ntawm tus po thiab kev loj hlob ntawm spleen hlwb nyob rau hauv nteg hens tsa nyob rau hauv txawv monochromatic lub teeb ib puag ncig, thiaj li yuav muab cov ntaub ntawv yooj yim rau lub teeb pom kev zoo ntawm cov nqaij qaib kev lag luam.
The results showed that the diameter of spleen corpuscles in the red light group increased with the increase of the age from 20 weeks to 37 weeks, and there was no significant change from 37 weeks to 52 weeks (P>0.05);
Txawm hais tias thaj tsam ntawm lymphatic sheath nyob ib ncig ntawm cov hlab ntsha splenic txo qis thaum muaj hnub nyoog 37 lub lis piam, nws rov zoo dua thaum muaj hnub nyoog 52 lub lis piam. Cov txiaj ntsig kev sim qhia tau hais tias lub teeb liab tuaj yeem txhim kho lub cev tiv thaiv kab mob ntawm cov kab mob spleen ntawm nteg qe qe nyob rau theem lig ntawm kev tso.
