Cov teebmeem ntawm Lub Teeb Xim rau Poultry Health thiab Welfare

Vim li cas cov teeb pom kev zoo tseem ceeb?

Lub teeb yog qhov tseem ceeb rau txoj kev loj hlob ntawm cov nqaij qaib vim cov neeg ua liaj ua teb nrhiav kev tsim cov xwm txheej zoo tshaj plaws rau cov noog kom paub txog lawv cov peev xwm ntawm caj ces tag nrho. Kev txiav txim siab yuav tsum tau muab rau cov yam ntxwv xws li lub teeb pom kev, wavelength, photoperiod (kev teeb tsa ntawm lub teeb-dub mus), lub teeb siv, thiab lub koom haum photosource.

Ntau txoj kev tshawb fawb tau ua tiav ntawm photoperiods thiab siv lub teeb, tab sis tsawg dua tau ua tiav ntawm qhov zoo ntawm ntau yam teeb pom kev zoo thiab wavelengths (xim).

Cov kev tshawb fawb yav dhau los tau qhia tias lub teeb xiav tuaj yeem txo qhov kev ntxhov siab thiab txhawb kev loj hlob ntawm hens, tab sis muaj lus nug txog seb cov noog puas yuav tsis pom kev pom thaum raug ib lub teeb ntawm lub teeb. Tsis tas li ntawd, lwm cov kev tshawb fawb tau qhia tias lub teeb liab txhawb lub qe tsim, clouding qhov teeb meem ntawm lub teeb hom twg yog qhov tseem ceeb tshaj plaws.

Cov noog muaj lub teeb pom kev sib txawv ntawm tib neeg txij li lawv tuaj yeem pom nyob rau hauv ob qho tib si pom thiab UV ntau yam, ntxiv rau muaj qhov pom lub teeb pom kev hauv lub cev tsis yog qhov muag. Los ntawm kev hloov pauv hauv cov tshuaj hormones, cov ntaub ntawv teeb pom kev zoo uas cov noog lub hlwb txheej txheem tseem ceeb heev rau kev tswj cov metabolism thiab kev tiv thaiv kab mob.

Puas yog broilers nyiam 'sov' lossis 'txias' xim xim?

Lub teeb-Emitting Diodes, lossis LEDs, yog lub zog hloov pauv rau cov teeb pom kev zoo fluorescent ntau pom hauv cov tsev qaib. Cov kev txhawb zog muaj zog los siv cov cuab yeej no los ntawm cov nqi hluav taws xob tsis zoo thiab kev loj hlob tsom mus rau cov txheej txheem kev lag luam ib puag ncig. Tsis tas li ntawd, lawv muaj lub neej siv tau ntev, uas txo cov nqi kho thiab hloov pauv.

Txoj kev tshawb fawb tau tshawb xyuas qhov tshwm sim ntawm ob lub LEDs nrog ntau yam "xim kub", raws li ntsuas hauv Kelvin (K). Cov kab lus no piav qhia tias cov teeb pom kev dawb thiab daj zoo li muaj xim, nrog cov xim zoo nkauj uas muaj xim kub thiab lwm yam.

Hauv kev tshawb nrhiav, ob xim kub tau siv rau hauv cov tsev qaib. Lub teeb "nruab nrab-dawb" ntawm 4,100 K yog piv rau cov xim kub ntawm cov teeb pom kev zoo ib txwm ua haujlwm hauv Danish broiler tsev.

Lwm lub teeb pom kev zoo, uas muaj xim kub ntawm 6,065 K, yog hu ua "txias-dawb" vim nws tawm ntau lub teeb nrog xiav spectral yam ntxwv. Lub teeb no tau xaiv vim nws cov xim kub ua raws li lub hnub ci ntuj nyob rau hauv ib hnub huab cua nyob rau hauv lub tropics, ua rau nws zoo li lub instinctive xaiv rau ib tug poj koob yawm txwv ntawm tam sim no hens.
