Magalasi a nkhuku a pulasitiki, omwe amadziwikanso kuti nkhuku, ndi magalasi ang'onoang'ono, okhazikika omwe amapangidwira nkhuku. Magalasi amenewa nthawi zambiri amapangidwa ndi zinthu zapulasitiki zapamwamba kwambiri ndipo amabwera ndi timaboti ting'onoting'ono tomwe timamatira mosavuta kumutu wa nkhuku. Cholinga chachikulu cha magalasiwa ndi kupititsa patsogolo khalidwe ndi thanzi la nkhuku zopanda malire. Mapangidwe a magalasi a nkhuku apulasitiki amakhala ndi tinthu tating'onoting'ono tozungulira tomwe timakhala patsogolo pa maso a nkhuku. Magalasiwa amayikidwa bwino kuti nkhuku isayang'ane kutsogolo, kuti isayang'ane kutsogolo. Pochita izi, magalasi amathandizira kuchepetsa chiwawa ndi khalidwe loyang'ana pakati pa zoweta, motero kuchepetsa kuvulala ndi kupsinjika pakati pa ziweto. Zinthu zapulasitiki zomwe zimagwiritsidwa ntchito m'magalasi ndizopepuka, zomasuka komanso zopanda vuto kwa nkhuku.
Kuphatikizika kwa mabawuti ang'onoang'ono kumatsimikizira kulumikizidwa kotetezeka kumutu wa nkhuku popanda kuyambitsa kusapeza bwino kapena kulepheretsa kuyenda kwake kwachilengedwe. Ndipotu, magalasi a nkhuku a pulasitiki amagwiritsidwa ntchito kwambiri poweta nkhuku zamalonda, kumene nkhuku nthawi zambiri zimaleredwa m'malo ovuta kwambiri. Pochepetsa mawonedwe, magalasi amatha kuchepetsa khalidwe laukali, kujowina ndi kudya nyama, motero kumapangitsa kuti ziweto zikhale bwino komanso zokolola. Kuphatikiza apo, atha kugwiritsidwa ntchito m'malo opanda ufulu kuteteza nkhuku kuti zisamenyedwe ndi kuvulala. Magalasi awa ndi osavuta kukhazikitsa ndi kuchotsa ndipo amatha kusamalidwa mosavuta ndikusintha ngati pakufunika. Oweta nkhuku ndi oweta amapeza njira yabwino yothanirana ndi vuto la nkhuku. Ponseponse, galasi la nkhuku la pulasitiki lopangidwa ndi bolt limapereka chida chothandiza komanso choyenera polimbikitsa ubwino wa nkhuku m'madera osiyanasiyana a ulimi. Kumanga kwawo kokhazikika, kugwiritsa ntchito mosavuta komanso zotsatira zabwino pamakhalidwe a ziweto zimawapangitsa kukhala ofunikira pakuweta nkhuku.
