\u00cen\u021belegerea stresului termic \u0219i rolul umidit\u0103\u021bii<\/strong><\/p>\n

Stresul termic apare atunci c\u00e2nd animalele nu pot elimina eficient excesul de c\u0103ldur\u0103 din corp, perturb\u00e2nd capacitatea de a men\u021bine o temperatur\u0103 corporal\u0103 stabil\u0103. De\u0219i temperaturile ambientale ridicate sunt cauza principal\u0103, umiditatea ridicat\u0103 agraveaz\u0103 situa\u021bia, \u00eempiedic\u00e2nd mecanismele de r\u0103cire prin evaporare, cum ar fi respira\u021bia accelerat\u0103 sau transpira\u021bia. <\/p>\n

Pentru a \u00een\u021belege mai bine efectele combinate ale c\u0103ldurii \u0219i umidit\u0103\u021bii, \u00een special asupra p\u0103s\u0103rilor \u0219i porcinelor, Indicele Temperatur\u0103 \u2013 Umiditate (ITU \u2013 Temperature \u2013 Humidity Index) este utilizat pe scar\u0103 larg\u0103 ca un indice real care reflect\u0103 nivelul de stres termic.

Consecin\u021bele stresului termic la p\u0103s\u0103ri \u0219i rolul amplific\u0103rii c\u0103ldurii<\/strong><\/p>\n

Stresul termic la p\u0103s\u0103ri este o problem\u0103 grav\u0103, care apare atunci c\u00e2nd temperatura intern\u0103 a corpului dep\u0103\u0219e\u0219te pragul normal, situat de obicei \u00eentre 39,5-41\u00b0C, \u00een func\u021bie de v\u00e2rst\u0103. Dac\u0103 temperatura corpului dep\u0103\u0219e\u0219te 41\u00b0C, aceasta poate cauza leziuni celulare extinse, inflama\u021bie sistemic\u0103, \u0219oc circulator \u0219i, \u00een cele din urm\u0103, moartea. \u00cen\u021belegerea efectelor individuale \u0219i combinate ale temperaturilor ridicate \u0219i ale umidit\u0103\u021bii crescute asupra s\u0103n\u0103t\u0103\u021bii p\u0103s\u0103rilor este esen\u021bial\u0103 pentru a preveni pierderile \u0219i pentru a asigura bun\u0103starea animalelor. <\/p>\n

Spre deosebire de mamifere, p\u0103s\u0103rile nu au glande sudoripare \u0219i depind \u00een principal de mecanismele de r\u0103cire prin respira\u021bie (g\u00e2f\u00e2it) pentru a-\u0219i regla temperatura corpului. Acest lucru le face deosebit de vulnerabile \u00een medii cu temperaturi ridicate. Chiar \u0219i \u00een condi\u021bii de usc\u0103ciune, c\u00e2nd temperatura ambiental\u0103 se apropie sau dep\u0103\u0219e\u0219te temperatura corpului p\u0103s\u0103rilor (39,5-41\u00b0C), capacitatea lor de a radia c\u0103ldura este grav afectat\u0103. La acest prag, r\u0103cirea prin convec\u021bie (fluxul de aer) nu mai este eficient\u0103, iar respira\u021bia accelerat\u0103 devine singurul mecanism, cresc\u00e2nd semnificativ riscul de stres termic \u0219i deces. <\/p>\n

 <\/p>\n

Umiditatea agraveaz\u0103 stresul termic: Indicele termosensibil<\/strong><\/p>\n

Umiditatea spore\u0219te efectul temperaturii: De regul\u0103, pentru fiecare cre\u0219tere de 10% a umidit\u0103\u021bii, senza\u021bia de c\u0103ldur\u0103 resim\u021bit\u0103 va cre\u0219te cu aproximativ 2\u00b0C. De exemplu, o temperatur\u0103 de 30\u00b0C \u00eentr-un de\u0219ert uscat ar fi mult mai pl\u0103cut\u0103 dec\u00e2t 30\u00b0C \u00eentr-un mediu de jungl\u0103 umed\u0103. <\/p>\n

Indicele termosensibil \u0219i rata mortalit\u0103\u021bii: Calculatorul indicelui termosensibil ajut\u0103 la estimarea \u201etemperaturii senzoriale\u201d pe care pas\u0103rea o experimenteaz\u0103 de fapt. De exemplu, la 34\u00b0C \u0219i 40% umiditate, temperatura perceput\u0103 este de aproximativ 35\u00b0C. Cu toate acestea, dac\u0103 umiditatea cre\u0219te la 65%, indicele termosensibil poate ajunge la 44\u00b0C, cresc\u00e2nd brusc riscul de deces. <\/p>\n

Pe termen lung, poate cauza probleme intestinale, cum ar fi sindromul de intestin permeabil. <\/p>\n

Afectarea productivit\u0103\u021bii \u0219i a imunit\u0103\u021bii: Stresul termic cronic sl\u0103be\u0219te sistemul imunitar, reduce consumul voluntar de hran\u0103, scade eficien\u021ba digestiv\u0103 \u0219i absorb\u021bia nutrien\u021bilor \u0219i reduce rata de cre\u0219tere, produc\u021bia de ou\u0103 \u0219i fertilitatea.<\/p>\n
