I tēnei wā, kei te whakahaerehia ngā rangahau mō te whakamahinga ote whakahōputu pāhare pākawai roto i te whāngai manu, ko te nuinga o te aro ki ngā heihei broiler.

Te tāpiri i ngā horopeta rerekē opāhare pākawa(0,3,6,12g/kg) ki te kai a ngā heihei parai, i kitea ko te pāhare pākawa waro i whakanui ake i te kai e kainga ana (P<0.02), i whakanui ake i te ngāwari o te nakunaku me te whakatakotoranga hauota ki te kai, ā, i whakaatu i te pikinga o te taumaha o ia rā (P<0.7). I roto i ēnei, ko te tāpiri o te 6g/kg pāhare pākawa waro te hua pai rawa atu, i whakanui ake i te kai e kainga ana mā te 8.7% (P<0.01) me te taumaha mā te 5.8% (P=0.01).

I rangahauhia te pānga whakatairanga tipu o te pāhare pākawa waro ki ngā heihei tunu kai. I whakaatuhia e ngā hua whakamātautau ko te tāpiri i te 0.45% (4.5g/kg) pāhare pākawa waro ki te kai i whakapiki ake i te taumaha o ia rā o ngā heihei tunu kai mā te 10.26% me te tere tahuritanga whāngai mā te 3.91% (P<0.05), ka tutuki ai te pānga rite ki te flavomycin (p>0.05); Ā, i tino whakaitihia te uara pH o te ara nakunaku, ka hua ake he hekenga o te 7.13%, 9.22%, 1.77%, me te 2.26% o ngā uara pH o te hua, te uaua puku, te jejunum, me te cecum.

Te Pānga o te Acidifier Potassium Diformate ki te Mahi Whakaputa o ngā Broilers:

Mā te tāpiri i ngā mea whakakawa ki te kai ka taea te whakaiti i te pH o te puku o ngā heihei parai, te whakaiti i te nui o te Escherichia coli, te whakanui ake i te nui o ngā huakita whai hua Lactobacillus, te whakaiti i te kukū o te waikawa uric toto i roto i ngā heihei parai, me te whakapai ake i te kaha ārai mate. Mā te tāpiri i te waikawa waro pāhare pākawa dicarboxylate ki te kai o ngā heihei parai ka tino whakaiti i te pH o te puku, ka whakanui ake i te teitei o ngā villus o te puku, ka pai ake te mimiti me te whakamahi i ngā matūkai, ā, ka pai ake te tipu. Kua kitea e ngā rangahau ka taea e ngā mea whakakawa te whakaiti i te pH me te waikawa o te kai heihei parai, ā, ka tino whakapai ake i te ngāwari o te nakunaku o te mea maroke, te pūngao, te pūmua, me te phosphorus i ia wāhanga o te kai.

Ngā pānga patu huakita me te patu huakita o te pāhare pākawa waro:

Ko te wāhanga matua o te pāhare pākawa waro, arā, te waikawa formic, he tino kaha ngā pānga patu huakita. Ka taea e te waikawa formic kore-wehewehe te uru ki roto i ngā pakitara pūtau huakita, ā, ka heke te uara pH i roto i te pūtau. Ko te pH i roto i ngā pūtau huakita e tata ana ki te 7. Kia uru ngā waikawa waro ki roto i ngā pūtau, ka taea e rātou te whakaiti, te aukati rānei i te mahi a ngā whākōkī ā-roto, me te whakaroa i te kawe i ngā matūkai, ā, ka ārai i te whakaputa uri o ngā huakita, ka mate ai. Ka pakaruhia e te anion formate ngā pūmua pakitara pūtau huakita i waho o te pakitara pūtau, ka puta he pānga patu huakita me te patu huakita. Ina heke te uara pH i roto i te ara nakunaku o ngā manu kāinga, he pai ki te whakahohe i te pepsin me te whakatairanga i te nakunaku o te kai; Hei tāpiri, ko te whakaiti i ngā huakita puku ka whakaiti i te kai o te pākia o ngā huakita me te whakaputanga o ngā paitini huakita. Mā te pānga ngātahi o ēnei āhuatanga e rua ka taea te nakunaku me te whakamahi i ngā matūkai maha atu e ngā kararehe, ā, ka whakatairanga i te tipu o ngā kararehe me te whakapai ake i te whai huatanga o te whakamahinga kai.

Pāhare pākawa DiformateKa whakatairanga i te tipu o ngā heihei parai:

I whakaatuhia e te whakamātautau ko te tere whakaora o te formate i roto i te puku he 85%. Mā te whakamahi i te horopeta 0.3%, i noho te pH o te chyme duodenal hou ki te 0.4 wae pH iti iho i te rōpū whakahaere i muri i te kai. Ka taea e te potassium dicarboxylate te whakaiti nui i te uara pH i roto i te puku hua me te uaua, ā, ka tutuki ai ngā pānga patu huakita me te whakatairanga tipu. Ka taea e te potassium formate te whakaiti i te maha o Escherichia coli me Lactobacillus i roto i te cecum, ā, ko te nui o te hekenga o Escherichia coli he teitei ake i te Lactobacillus, ā, ka mau tonu te āhua hauora i te wāhanga o muri o te whekau me te whakatairanga i te tipu o ngā heihei.
