Whakarāpopototanga Whakahaere
Kua tino whānui te rāngai ahuwhenua kōtare i Myanmar i roto i te haurua tekau tau kua pahure ake nei, nā te pikinga ake o te tono ā-whare mō ngā hua kōtare me te mīti puta noa i Yangon, Mandalay, me te Ayeyarwady Delta. Heoi, he nui te wāhanga o ngā mahi kōtare iti me te rahi-rahi e whakawhirinaki tonu ana ki ngā kai momo-parāoa – he tikanga whāngai he ngoikoretanga ā-roto: te wehewehe i ngā kai i te wā e kawe ana, te nui o te puehu e whakapataritari ana i ngā pūnaha manawa o ngā manu, me te whanonga whāngai whiriwhiri e whakararuraru ana i te ōritetanga o te kai. E whakaatu ana tēnei rangahau take i te wheako o tētahi rōpū mahi whāngai kōtare manu 60,000 i te Rohe o Bago i whakakapi i tana kaupapa whāngai e ahu mai ana i te parāoa ki tētahi pūnaha pellet i hangaia huri noa i te mira pellet mate mowhiti raupapa Hongyang HYPM me tētahi mate mowhiti i hangaia kia rite ki te hiahia. Tekau mā rua marama o ngā raraunga whakaputa ka tātarihia hei aromatawai i te kounga pellet, te whai huatanga o te whāngai, te mahi manu, me te pumau o te mahi.
1. Te Rāngai Koitareke o Myanmar me te Āputa Pellet
Ko te umanga heihei o Myanmar i aro nui ki ngā heihei parai me ngā heihei whāngai i ngā tau kua pahure ake nei, heoi, ko te whakatipu koitareke – inā koa ko ngā koitareke Hapanihi (Coturnix japonica) e whakatipuria ana mō te whakaputa hua manu – kua puta ake hei wāhi tipu tere. Ko ngā raraunga kāwanatanga i kohia e te Tari Whakatipu Kararehe me te Kararehe e whakaatu ana i neke atu i te 8 miriona manu te taupori koitareke ā-motu i te tau 2025, me te Rohe o Bago, te taha o Yangon, me Sagaing e kapi ana i te neke atu i te 60% o ngā whenua. Ko te nuinga o ngā mahi he mea hanga hei mahi tahi, hei whatunga whakatipu kirimana rānei e whakakotahi ana i te hoko kai, ngā ratonga kararehe, me te urunga mākete mō ngā kaipupuri iti takitahi.
Ahakoa tēnei tipu, kei te whakaroa te whakamahi i te hangarau whāngai. I kitea i roto i tētahi rangahau i te tau 2024 i whakahaerehia e te Rōpū Kararehe o Myanmar, tata ki te 70% o ngā kaihanga hua manu koitareke e kai tonu ana i ngā kai māngaro, ki te whakaritea ki te iti iho i te 30% e whakamahi ana i ngā kongakonga paraoa, i ngā pirepire rānei. Ko ētahi o ngā take he ōhanga - he whakapaunga pūtea ngā mira pirepire - me tētahi wāhi he āputa mōhiotanga mō ngā painga whakaputa ka taea e te whakamahi pirepire te tuku ki tētahi manu iti, he tairongo hoki ki te pākia o te tinana pērā i te koitareke.
2. Te Āhua Tīmatanga o te Mahi Tahi
Kei te 90 kiromita ki te raki-mā-rāwhiti o Yangon i te Rohe o Bago te mahi tahi, ā, e 60,000 pea ngā koitareke whāngai e noho ana i roto i ngā whare e ono e tuwhera ana ngā taha me te hauhautanga o te kauhanga. I mua i te whakapai ake i ngā taputapu, i tikina e te mahi tahi he paraoa witi-pīni soya mai i tētahi mira whāngai arumoni tata, ā, i konatunatua ki te raihi me te kōhatu kōhatu i hokona mai i te rohe, ā, i hoatu te kai kua oti hei paraoa maroke.
I whakaatuhia e ngā inenga turanga i kohia i roto i te wā e ono marama i mua i te whakahoutanga ngā mea e whai ake nei:
Ōwehenga Tahuritanga Whāngai (FCR): 2.85 kg whāngai mō ia kg o ngā hua manu i whakaputaina (te toharite taumaha puta noa i ngā whare whāngai e ono). Te Kai Whāngai o ia Rā mō ia manu: 26.5 karamu, me te matapae o te maringi me te ngaronga puehu tata ki te 8–10% i waenga i ngā waka whakaranu me ngā paepae whāngai. Te Whakaputa Hua Manu i te Rā Heihei: 82.3% (te toharite puta noa i ngā whare whāngai; ko te whare whāngai pai rawa atu ko te 85.1%, ko te ngoikore rawa ko te 78.6%). Te Mate: 1.9% mō ia huringa whakaputa 28-rā, ā, ko ngā raruraru manawa te wāhanga nui o te tango i ngā manu.
E toru ngā āhuatanga uaua i kitea e ngā kaiwhakahaere mahi tahi: te moumou nui o te kai i te wā e whāngai ana, te koretake o te kai matūkai nā te mea ka kohia e ngā manu ngā matūriki nunui, ā, ka waiho te paura pai ki muri, me ngā pupuhi manawa i puta mai i te puehu i te wā maroke (Whiringa-ā-rangi–Hui-tanguru).
3. Te Ara Whakatau
I muri i te aromatawai i ngā tono mai i ngā kaiwhakarato taputapu e toru, i whiriwhiria e te rōpū mahi tahi tētahi mira pellet mowhiti mate raupapa Hongyang HYPM i whakatauria ki te 3–5 tāne ia hāora – he tauine e hangai ana ki te putanga mahi a te rōpū mahi tahi, e tata ana ki te 3.2 tāne ia rā. I runga i ētahi whakaaro te whakataunga:
1. Ngā whakaurunga tohutoro ā-rohe. I whakatūria e Hongyang tētahi waeine HYPM i tētahi mira whāngai paparanga kei Yangon i ngā marama 14 ki muri; i toro atu ngā māngai mahi tahi ki te papaanga, ā, i mātakitaki i te mahi pumau.
2. Te āheinga whakarite mō te mowhiti mate. Ko te whāngai koitareke me whai diameter pellet kua oti i waenga i te 1.5 mm me te 2.5 mm – he iti ake i ngā pellet 3–5 mm e whakamahia ana mō ngā heihei tunu me ngā heihei whāngai. I tukuna e te tīma hangarau a Hongyang he mowhiti mate i hangaia mō tēnei kaupapa me te diameter kōhao, te ōwehenga kōpeketanga, me te mahi whakarewa e tika ana mō tēnei tono.
3. Te tata ki muri i te hoko. I taea e tētahi tohunga hangarau i Yangon, kua whakangungua ki Hongyang, te tirotiro i te tāutanga me te whakahaere i te huringa tiaki tuatahi kua whakaritea i te papaanga.
4. Te Hangarau Mowhiti Mate mō te Whāngai Koitareke
Ko te mati mowhiti te ngākau o tētahi mira pirepire, ā, ko ōna tawhā hoahoa te mea e whakahaere tika ana i te kounga o te pirepire, te tere whakaputa, me te whakapaunga pūngao mō ia tana. Mō tēnei tono whāngai koitareke, i tukuna e Hongyang he mati mowhiti kua whirihorahia ki ngā whakaritenga e whai ake nei:
Rauemi o te mate: maitai koranu 20CrMnTi, kua whakakāhia ki te waro me te tineia ki te korehau. Pakari o te mata: HRC 58–62. Diameter o te kōhao: 2.0 mm. Ōwehenga kōpeketanga whai hua (L/D): 1:8.5. Whānui mahi o te mate: 140 mm. Whirihoranga whakawhāiti: Putanga whakarara me te whakawhāiti porotaka, pūaha whakamuri 3-wāhanga. Tukatuka-muri: Oro maha-wāhanga ki te taratara o roto o te kōhao Ra–0.8 µm.
He aha te hiranga o ēnei kōwhiringa. Ko te ōwehenga kōpeketanga 1:8.5 he mea āta tiakina mō te ōwehenga paparanga koitareke muka-teitei (muka mata - 4.2%) hei karo i te waku nui o te mate me te whakaputa wera, ka taea te whakaheke i ngā huaora kore-wera me ngā waikawa amino hangai. Ko te koranu 20CrMnTi me te tinei korehau ka puta he paparanga mata martensitic e ātete ana ki te kakahu me te pumau o te taha i raro i te huringa wera e rite ana ki ngā mahi tīmatanga-mutu o ia rā. Ko te awhina o te counterbore e toru-wāhanga ka whakaiti i te pēhanga whakamuri i te putanga o te mate, ka whakaiti i te whakapaunga pūngao motuhake me te pupuri tonu i te pono o te pire. Ka puritia te manawanui o te diameter o te poka ki te ± 0.05 mm, kia whakarite kia puta he pire i roto i te roopu rahi piripono ia o ia poka mate 1,400+ - he mea nui ina whāngai ana i te manu he torutoru mirimita te whānui o te ngutu.
5. Te Whakanui Ake i te Whakaputa me te Mahi Āhua-Pūmau
I oti te tāutanga i roto i te matapihi e rima ngā rā i te wā o te whakamutu whakaputa kua whakaritea. I whakauruhia te mira pirepire ki raro i te mīhini whakaranu rīpene o mua, ki runga ake hoki i te mīhini whakamatao rere-whakamuri, ka hanga he raina pirepire tonu. I whakapūmautia te pāmahana whakatikatika ki te 78–82°C me te wā noho o te 45–50 hēkona, mā te whakamahi i te mamaoa maroke kua mākū i te 2.5 pae – i tae mai ngā tawhā mā roto i tētahi kawa whakatūnga hanganga e uru ana ki ngā whakatikatika ā-piki ake i roto i te 14 ngā puranga.
I whakawhitihia e te rōpū mahi tahi ngā whare manu e ono ki te whāngai i roto i ngā pirepire mō te wā e toru wiki kia taea ai e ngā manu te urutau mārire. I kohia ngā raraunga i muri i te whakawhiti mai i te marama 4 ki te marama 12, i te taenga o te pūnaha ki te āhua pumau, ā, kua taunga katoa ngā rōpū manu:
FCR (kg whāngai / kg hua manu): 2.85 i mua i te whakapai ake vs 2.47 i muri i te whakapai ake, he whakahekenga o te 13.3%. Te kai whāngai o ia rā (g/manu): 26.5 i mua i te whakapai ake vs 24.8 i muri i te whakapai ake, he whakahekenga o te 6.4%. Te moumou whāngai (% o te whāngai i tukuna): 8–10% i mua i te whakapai ake vs iti iho i te 2% i muri i te whakapai ake, he whakahekenga tata ki te 80%. Te whakaputanga hua manu i te rā o te heihei: 82.3% i mua i te whakapai ake vs 86.9% i muri i te whakapai ake, he pikinga o te 4.6 ōrau. Te Taupū Pakari o te Pīreti (PDI): 96.8% i muri i te whakapai ake (kāore e pā ana i mua i te whakapai ake). Te pakeke o te pīreti: 1.2–1.5 kg i muri i te whakapai ake (kāore e pā ana i mua i te whakapai ake). Te mate mō ia huringa: 1.9% i mua i te whakapai ake vs 1.3% i muri i te whakapai ake, he whakahekenga o te 0.6 ōrau. Hiko: 14.8 kWh/tāne pereti i muri i te whakapai ake (kāore e tika mō mua i te whakapai ake).
Ko te uara PDI o te 96.8%, i inehia ia hauwhā mā te whakamahi i te taputapu whakamātautau Holmen, e tohu ana i te kaha o te pumau o te pirepire mā te kawe, te rokiroki ipu, me te tohatoha auger. Ko te wāhanga paitini - te rauemi i whiti i te tātari 1.0 mm - i noho tonu i raro iho i te 1.5% o te katoa o te putanga, i kīia e ngā kaimahi mahi tahi nā te āhua o te kōhao ōrite me ngā mata o roto o te mowhiti mate Hongyang.
6. Ngā Huanga Whai Hua mō te Mahi Tahi
Haunga ngā pikinga tatauranga, i kitea ētahi panonitanga whakahaere i ngā haerenga tirotiro me ngā uiuinga a ngā kaiahuwhenua i whakahaerehia i te wā i muri i te whakahoutanga:
Te ōritetanga o te whanonga whāngai. Kua tino heke te auau o te whāngai whiriwhiri - arā, ko ngā manu e waru ana i te kai hei wehe i ngā matūriki pai. Nā te mea kei roto i ngā pirepire ngā wāhanga kai katoa i roto i ia wae motuhake, ka tukuna e ia pirepire he horopeta kai tino pai.
Hauora manawa. Ko te nui o te puehu i inehia i roto i ngā whare putunga i heke mai i te toharite o te 2.8 mg/m³ ki te 0.7 mg/m³ i te wā maroke, ā, i te wā kotahi anō hoki, kua heke te nui o ngā puehu e pā ana ki te manawa mai i te 0.7% ki te 0.3% ia huringa.
Te kounga o te anga hua manu. Ko te matotoru anga o ngā hua manu mai i ngā kahui i whāngaihia ki te pellet he 0.196 mm te toharite, he 0.183 mm te rerekē ki te 0.183 mm i raro i te tikanga kuru, he whakapainga tēnei i kīia e te tohunga kai o te mahi tahi nā te nui ake o te wātea o te konupūmā me te whākōkī i roto i te matrix pelleted i reira ka herea ngā paihere kōhatu kaua e tau ki waho.
Te whakapono o te kaiwhakahaere. I rere tonu te mira pirepire mō ngā rā 22–23 i ia huringa 28-rā, me te wā whakatā kua whakaritea kia herea ki te tirotiro i te mate me te whakahinuhinu auau. Kāore i tuhia he aukati kore i whakamaheretia nā te mira pirepire, te mate mowhiti rānei i roto i te matapihi aromatawai 9-marama.
7. Anga Kounga a Hongyang
Ko te mahi i kitea i tēnei mahi tahi Bago e whakaata ana i tētahi huinga o ngā momo mahi hanga kua whakauruhia ki roto i te raina whakaputa mowhiti mate a Hongyang:
Te whai i ngā rauemi mata. Ka tohaina he tau wera ki ia mowhiti mate e hono ana ki te tiwhikete mira maitai taketake, e tuhi ana i te hanganga matū me ngā āhuatanga miihini i mua i te tīmatanga o te miihini.
Te tikanga tinei korehau. Ka whakahaerehia te maimoatanga wera i roto i te oumu korehau me te whakahaere pāmahana maha-rohe, ā, muri iho ka whakahaerehia te maimoatanga hohonu ki te cryogenic hei huri i te austenite kua puritia hei martensite - he taahiraa e whakau ana i te hanganga moroiti o te mate me te whakaroa i te roa o te mahi i raro i te ahotea wera auau.
Ine i ngā teihana maha. Ka tirohia te whānui o te kōhao, te teitei, me te āhua o te poka whakamuri me ngā mīhini ine taunga (CMM) i ngā wāhanga e toru: i muri i te keri pū, i muri i te maimoatanga wera, me muri i te oro whakamutunga. Ko ngā mate e taka ana i waho o te ātete ±0.05 mm ka whakakahoretia i mua i te tukunga.
Te whakamātautau i mua i te tukunga. Ka whakamatautauria ia mira pirepire HYPM ki te whakamātautau kore-kawenga me te whakamātautau uta poto i te wheketere i mua i te whakakī ki roto i te pouaka, kia mōhio ai kei te tutuki i ngā whakaritenga te ātea o te roera-mate, ngā pāmahana o te peera, me ngā taumata wiri.
Ehara ēnei i te kereme hokohoko; he kuaha whakahaere kounga kua tuhia e te kaihoko ka taea te manatoko i te wā o te arotake wheketere - he kōwhiringa e hiahia ana te mahi tahi ki te whakamahi ina whakawhānui atu ki tētahi raina whakaputa tuarua.
8. Whakarāpopototanga
E whakaatu ana te wheako o te rōpū mahi tahi o Bago, mā te whakawhiti i ngā whāngai whāngai koitareke mai i te momo mash ki te momo pellet, mā te whakamahi i ngā taputapu pellet kua tohua tika me te mowhiti mate i hangaia mō te tono, ka taea te whakaputa i te whakapainga rua-mati i roto i te pai o te whakawhiti whāngai me te whakaiti i te para, te whakaū i te hauora o te kahui, me te whakapiki ake i te putanga hua. Ko te mira pellet mowhiti mate raupapa Hongyang HYPM, i honoa ki te mowhiti mate 20CrMnTi ritenga i hangaia ki ngā manawanui ā-ahu me te ōwehenga kōpeketanga ātaahua, i tukuna he putanga pono puta noa i te iwa marama o te mahi arumoni tonu - me te kore he wehenga kore i whakamaheretia e hono ana ki te raina pellet. Mō te rāngai koitareke e tipu haere ana o Myanmar, kei reira ngā tawhē e hangaia ana e te utu whāngai me te utu hua manu, ko tēnei momo haumi taputapu kua whakaritea ka tuku i te ara mahi ki te ōhanga waeine pai ake.
Ngā Pūtake Raraunga: Ngā Rārangi Whakaputa Mahi Tahi (Hanuere 2025 – Maehe 2026), ngā pūrongo tātari pirepire ā-hauwhā, te Tatauranga Koitareke a te Tari Whakatipu Kararehe me te Kararehe (2025), te Rangahau Mahi Whāngai a te Rōpū Whakatipu Kararehe o Myanmar (2024). Kei te wātea ngā whakaahua me ngā tuhipoka toro ki te wāhi e hiahiatia ana.
