Nqaij qaib tuaj yeem paub qhov txawv ntawm cov xim sib txawv thiab kev siv zog ua tsaug rau lawv cov peev xwm ua kom pom tseeb. Txhawm rau tshawb xyuas qhov cuam tshuam ntawm lub teeb monochromatic rau kev loj hlob thiab kev tsim khoom ntawm broilers thiab nteg hens, xaiv LED teeb, lub teeb ci nrog ib lub wavelength, kom irradiate cov tsiaj. Txoj kev tshawb nrhiav pom tau hais tias pawg teeb ntsuab ntawm cov qaib broiler tau hnyav dua sai dua thiab muaj qhov tsawg dua pub-rau-nqaij piv thaum lub sijhawm loj hlob; cov pab pawg xiav lub teeb tau nce qhov hnyav thiab muaj qhov qis tshaj qhov pub-rau-nqaij piv nrog rau qhov hnyav tshaj plaws carcass, lub mis hnyav, tus ncej puab, qhov hnyav, thiab qhov hnyav. Qhov taw qhia ntawm qhov hnyav eviscerated yog 14.39 feem pua -19.86 feem pua ntau dua li lwm yam teeb. Hauv lwm lo lus, piv rau lub teeb liab thiab dawb, lub teeb ntsuab txhawb kev loj hlob ntawm broiler nyob rau lub sijhawm loj hlob thaum ntxov thaum lub teeb xiav txhawb kev loj hlob ntawm broiler hauv lub sijhawm loj hlob. Broilers tau raug lub teeb fluorescent tib lub sijhawm, thiab nws tau pom tias broilers tsa hauv lub teeb xiav-ntsuab tau nce ntau qhov hnyav dua li cov broilers tsa hauv lub teeb liab thiab dawb. Cov kev tshawb pom tau nthuav tawm saum toj no tag nrho qhia tias lub teeb monochromatic tuaj yeem cuam tshuam loj rau qaib kev loj hlob thiab kev loj hlob. Tus cwj pwm ntawm broilers tuaj yeem cuam tshuam los ntawm ntau lub teeb wavelengths. Piv txwv li, broilers loj hlob nyob rau hauv ib cheeb tsam liab thiab dawb yog sluggish, whereas broilers nyob rau hauv ib tug xiav thiab ntsuab ib puag ncig siv sij hawm ntau noj tsis tu ncua. Qhov no tuaj yeem yog qhov ua rau cov broilers tau tsa nyob rau hauv lub teeb xiav-ntsuab uas muaj lub cev hnyav dua, cov leeg ntawm lub mis hnyav, ncej puab luj, calf hnyav, thiab eviscerated hnyav dua li cov uas tau tsa hauv qab lub teeb liab thiab dawb.
The hub of the body's cellular and humoral immunity, the spleen is the largest immunological organ in the animal body and contains a significant number of lymphocytes and macrophages. When humoral immunity occurs, lymphoid nodular hyperplasia, plasma cells, and macrophages in the splenic cord dramatically increase. Cellular immunity results in a thickening of the lymphatic sheath around the artery. In order to provide fundamental knowledge for lighting in the poultry industry, laying hens' spleens were studied for morphological changes and differences in spleen cell proliferation using HE histological staining and immunohistochemical staining techniques. The findings revealed that the red light group's splenic corpuscle diameter rose with age from 20 weeks to 37 weeks, but that there was no significant change from 37 weeks to 52 weeks (P>0.05); Tsis tas li ntawd, thaj chaw lymphatic sheath nyob ib puag ncig cov hlab ntsha splenic nthuav tawm qhov nce ntxiv nrog hnub nyoog. Thaum 52 lub lis piam, nws tau nce txawm tias tau txo mus rau 37 lub lis piam. Cov txiaj ntsig kev ntsuam xyuas pom tau hais tias lub teeb liab tuaj yeem txhim kho splenocyte immunological muaj nuj nqi hauv kev tso hens thaum lub sij hawm pw lig.
