1: Ke koho ʻana i ka manawa wean

Me ka piʻi ʻana o ke kaumaha o nā puaʻa, piʻi mālie ka pono o nā meaʻai i kēlā me kēia lā.Ma hope o ke kiʻekiʻe o ka manawa hānai, pono e ukuhi ʻia nā puaʻa i ka manawa kūpono e like me ka nalowale o ke kaumaha o nā lūlū a me ka Backfat.ʻO ka hapa nui o nā mahiʻai nui e koho i ka wean no kahi o 21 mau lā, akā ʻo ke koi o ka ʻenehana hana kiʻekiʻe no 21 lā weaning.Hiki i nā mahiʻai ke koho i ka wean no nā lā 21-28 e like me ke ʻano o ke kino o nā lūlū (backfat loss < 5mm, body weight loss <10-15kg).

2: Ka hopena o ka weaning ma luna o nā Piglets

ʻO ke koʻikoʻi o nā puaʻa wean e komo pū ana: ka hoʻololi ʻana i ka hānai, mai ka hānai wai i ka hānai paʻa;Ua hoʻololi ʻia ke ʻano o ka hānai ʻana a me ka mālama ʻana mai ke keʻena hānai a hiki i ka nursery;ʻO ke ʻano o ka hakakā ʻana ma waena o nā hui a me ka ʻeha noʻonoʻo o nā puaʻa weaned ma hope o ka haʻalele ʻana i nā lūlū.

ʻO ka maʻi koʻikoʻi weaning (pwsd)

E pili ana i ka maʻi maʻi nui, ka momona momona, ka liʻiliʻi o ke ola ʻana, ka maikaʻi ʻole o ka hoʻohana ʻana i ka hānai, ka ulu lohi, ka stagnation o ka ulu a me ka ulu ʻana, a me ka hoʻokumu ʻana i nā puaʻa ʻoʻoleʻa i kumu ʻia e nā kumu koʻikoʻi i ka wā o ka weaning.

ʻO nā hōʻailona nui o ka maʻi e like me kēia

ʻAi puaʻa:

ʻAʻole ʻai kekahi mau puaʻa i nā meaʻai i loko o 30-60 mau hola o ka weaning, stagnation o ka ulu ʻana a i ʻole ka loaʻa ʻana o ke kaumaha maikaʻi ʻole (i kapa ʻia ʻo ka momona momona), a hoʻonui ʻia ka pōʻai hānai ma mua o 15-20 mau lā;

ʻO ka ʻōpū:

ʻO ka maʻi maʻi he 30-100%, me ka awelika o 50%, aʻo ka nui o ka make nui he 15%, me ka edema;

Hoʻemi ʻia ka palekana:

ʻO ka maʻi maʻi ke alakaʻi i ka emi ʻana o ka pale ʻana, nāwaliwali ke kūʻē ʻana i ka maʻi, a me ka maʻi maʻalahi o ka lua o nā maʻi ʻē aʻe.

ʻO nā loli pathological e like me kēia

ʻO ka maʻi microorganism pathogen kekahi o nā kumu nui o ka maʻi maʻi i hoʻokumu ʻia e ka maʻi koʻikoʻi i nā puaʻa weaned.ʻO ka maʻi maʻi i hoʻokumu ʻia e ka maʻi bacteria ka mea maʻamau e ka pathogenic Escherichia coli a me Salmonella.ʻO ka mea nui kēia ma ka lactation, no ka mea, ʻo nā antibodies o ka waiū umauma a me nā mea pale ʻē aʻe i ka waiū keʻakeʻa i ka hana hou ʻana o E. coli, ʻaʻole i ulu nā puaʻa i kēia maʻi.

Ma hope o ka weaning, e emi ana nā enzyme digestive i loko o ka ʻōpū o nā puaʻa, e emi ana ka digestion a me ka absorption o nā meaʻai meaʻai hānai, hoʻonui ka pala o ka protein a me ka fermentation ma ka ʻaoʻao hope o ka ʻōpū, a ke hoʻopau ʻia ka hāʻawi ʻana i nā antibodies makuahine, ka hopena i ka emi ʻana. ʻo ka palekana, kahi maʻalahi e hoʻoulu i ka maʻi a me ka maʻi maʻi.

Physiologic:

ʻAʻole lawa ka hoʻoheheʻe ʻia ʻana o ka ʻōpū;Ma hope o ka weaning, hoʻopau ʻia ke kumu o ka lactic acid, liʻiliʻi loa ka huna ʻana o ka waikawa gastric, a ʻaʻole lawa ka acidity i loko o ka ʻōpū o nā puaʻa, e kaupalena ana i ka hoʻoulu ʻana o Pepsinogen, e hōʻemi i ka hoʻokumu ʻana o ka pepsin, a pili i ka digestion hānai, ʻoi aku ka protein.Hāʻawi ka hānai indigestion i nā kūlana no ka hana hou ʻana o ka pathogenic Escherichia coli a me nā hua bacteria pathogenic ʻē aʻe i loko o ka ʻōpū liʻiliʻi, ʻoiai ke kāohi ʻia ka ulu ʻana o Lactobacillus, Ke alakaʻi nei ia i ka indigestion, intestinal permeability disorder a me ka diarrhea i nā puaʻa, e hōʻike ana i ka maʻi kaumaha;

ʻOi aku ka liʻiliʻi o nā enzyme digestive ma ka ʻōpū o ka ʻōpū;I ka makahiki 4-5 mau pule, ʻaʻole i oʻo ka ʻōnaehana digestive o nā puaʻa a ʻaʻole hiki ke hūnā i nā enzyme digestive.ʻO ka weaning piglets kahi ʻano koʻikoʻi, hiki ke hōʻemi i ka ʻike a me ka hana o nā enzyme digestive.ʻO nā puaʻa weaned mai ka waiū umauma a hiki i ka meaʻai mea kanu, ʻelua kumu ʻai meaʻai like ʻole, hui pū ʻia me ka ikehu kiʻekiʻe a me ka hānai protein kiʻekiʻe, ka hopena i ka maʻi maʻi ma muli o ka ʻai ʻole.

Nā kumu hānai:

Ma muli o ka liʻiliʻi o ka huna ʻana o ka wai ʻōpū, ka liʻiliʻi o nā ʻano enzyme digestive, ka haʻahaʻa o ka hana enzyme, a me ka lawa ʻole o ka ʻōpū o ka ʻōpū, inā kiʻekiʻe loa ka protein i loko o ka meaʻai, e hōʻeha ia i ka ʻai ʻana a me ka maʻi maʻi.He mea maʻalahi ka momona o ka momona i loko o ka meaʻai, ʻoi aku ka momona o nā holoholona, ​​​​e hana i ka maʻi maʻi i nā puaʻa weaned.Hiki i nā mea kanu lectin a me ka antitrypsin i ka hānai ke hoʻemi i ka nui o ka hoʻohana ʻana i nā huahana soybean no nā puaʻa.ʻO ka protein antigen i loko o ka protein soybean hiki ke hoʻoulu i ka maʻi maʻi o ka ʻōpū, atrophy villus, hoʻopilikia i ka ʻeli ʻana a me ka absorption o nā meaʻai, a hiki i ka weaning stress syndrome i nā puaʻa.

Nā kumu kaiapuni:

Ke ʻoi aku ka ʻokoʻa o ka mahana ma waena o ke ao a me ka pō ma mua o 10 ° Ke kiʻekiʻe loa ka haʻahaʻa, e piʻi pū ka maʻi maʻi maʻi.

3： Hoʻohana ʻia ka hoʻohana ʻana i ke kaumaha weaning

ʻO ka pane maikaʻi ʻole i ka weaning stress e hoʻopilikia i nā puaʻa, me ka atrophy o ka villi ʻōpū liʻiliʻi, ka hohonu o ka crypt, ka loaʻa ʻana o ke kaumaha maikaʻi ʻole, ka piʻi ʻana o ka make, a me nā mea ʻē aʻe, a me nā maʻi like ʻole (e like me Streptococcus);ʻO ka uluʻana o nā puaʻa me ka hohonu o ka maka a me ka gluteal groove ua emi nui, aʻo ka manawa pepehi e hoʻonuiʻia ma mua o hoʻokahi mahina.

Pehea e hoʻomalu ai i ka hoʻohana ʻana i ka weaning stress, e hoʻomaikaʻi mālie i nā puaʻa i ke kiʻekiʻe o ka hānai ʻana, ʻo ia ka ʻike o ka ʻōnaehana ʻenehana ʻekolu pae, e hana mākou i kahi wehewehe kikoʻī ma nā ʻāpana ma lalo.

Nā pilikia i ka wean a me ka mālama

1: ʻOi aku ka nui o ka momona momona (ke kaumaha kaumaha) i ka weaning ≤ 7d;

2: Ua hoʻonui ʻia ka nui o nā puaʻa ʻoʻoleʻa nāwaliwali ma hope o ka weaning (ka hoʻololi weaning, ka like ʻana o ka hānau ʻana);

3: Ua mahuahua ka make;

Ua emi ka ulu o ka puaʻa me ka ulu o ka makahiki.Ua hōʻike nā puaʻa i ka ulu kiʻekiʻe ma mua o 9-13w.ʻO ke ala e loaʻa ai ka uku hoʻokele waiwai maikaʻi loa pehea e hoʻohana piha ai i ka pono ulu i kēia pae!

Ua hōʻike nā hopena mai ka weaning a hiki i ka 9-10w, ʻoiai he kiʻekiʻe loa ka nui o nā pua puaʻa, ʻaʻole kūpono ia i ka hana puaʻa maoli;

Pehea e wikiwiki ai i ka uluʻana o nā pua puaʻa a hiki i ko lākou kaumaha 9W hiki i ka 28-30kg ke kī e hoʻonui ai i ka pono o ka hānai puaʻa, he nui nā loulou a me nā kaʻina hana e hanaʻia;

ʻO ka hoʻonaʻauao mua ʻana i ka wai a me ka ʻai meaʻai hiki ke hana i nā puaʻa i ka wai inu a me nā mākau hānai, hiki ke hoʻohana i ka hopena hānai nui o ka weaning stress, hoʻomaikaʻi i ka pae hānai ʻana o nā puaʻa, a hāʻawi i ka pāʻani piha i ka ulu ʻana o nā puaʻa ma mua o 9- 10 pule;

ʻO ka ʻai ʻana i loko o 42 mau lā ma hope o ka weaning e hoʻoholo i ka ulu ʻana o ke ola holoʻokoʻa!ʻO ka hoʻohana ʻana i ke koʻikoʻi wean e hoʻomaikaʻi i ke kiʻekiʻe o ka ʻai ʻana i ka meaʻai hiki ke hoʻonui i ka ʻai meaʻai 42 lā i kahi kiʻekiʻe e like me ka hiki.

ʻO nā lā e pono ai nā puaʻa e hiki i ka 20kg ke kaumaha o ke kino ma hope o ka wean ʻana (21 mau lā) he pilina nui me ka ikehu meaʻai.Ke piʻi ka ikehu digestible o ka meaʻai i ka 3.63 megacalories / kg, hiki ke hoʻokō ʻia ke kumukūʻai kumukūʻai maikaʻi loa.ʻAʻole hiki i ka ikehu digestible o ka meaʻai mālama mālama maʻamau ke hiki i 3.63 megacalories / kg.I ke kaʻina hana maoli, nā mea hoʻohui kūpono e like me "Tributyrin，Diludine"ʻO Shandong E.Fine hiki ke koho ʻia e hoʻomaikaʻi i ka ikehu digestible o ka meaʻai, i mea e hoʻokō ai i ka hana maikaʻi loa.

Hōʻike ka pakuhi:

He mea nui ka hoʻomau ʻana o ka ulu ʻana ma hope o ka wean!ʻO ka pōʻino i ka ʻāpana digestive ka liʻiliʻi loa;

ʻO ka palekana ikaika, ka liʻiliʻi o ka maʻi maʻi, ka pale ʻana i ka lāʻau lapaʻau a me nā lāʻau lapaʻau like ʻole, ke kūlana olakino kiʻekiʻe;

ʻO ke ʻano hana hānai mua: ua wean ʻia nā puaʻa, a laila nalowale ka momona o ka waiū, a laila hoʻihoʻi ʻia, a laila loaʻa ke kaumaha (e pili ana i 20-25 mau lā), e hoʻolōʻihi i ka pōʻai hānai a hoʻonui i ke kumukūʻai hānau;

ʻO nāʻano hānai i kēia manawa: e ho'ēmi i ka ikaika o ke kaumaha, e hoʻopōkole i ke kaʻina hana koʻikoʻi o nā puaʻa ma hope o ka weaning, e pōkole ka manawa o ka pepehi;

I ka hopena, hoʻemi ia i ke kumukūʻai a hoʻomaikaʻi i ka pono waiwai

ʻO ka hānai ʻana ma hope o ka ʻai ʻana

He mea koʻikoʻi loa ka piʻi ʻana o ke kaumaha i ka pule mua o ka weaning（ Piʻi kaumaha i ka pule mua: 1kg?160-250g / poʻo / W?) Inā ʻaʻole ʻoe e loaʻa ke kaumaha a i ʻole e lilo i ke kaumaha i ka pule mua, e alakaʻi ia i nā hopena koʻikoʻi;

Pono nā puaʻa wean mua i ka wela kūpono loa (26-28 ℃) i ka pule mua (ʻo ke kaumaha anu ma hope o ka weaning e alakaʻi i nā hopena koʻikoʻi): hoʻemi i ka ʻai ʻana i ka meaʻai, hoʻemi i ka digestibility, hoʻemi i ka pale ʻana i nā maʻi, ka maʻi maʻi, a me ka maʻi ʻino ʻole o ka ʻōnaehana lehulehu;

E hoʻomau i ka hānai ʻana i nā meaʻai ma mua o ka weaning (kiʻekiʻe ka palatability, kiʻekiʻe digestibility, kiʻekiʻe kiʻekiʻe)

Ma hope o ka weaning, pono e hānai ʻia nā puaʻa i ka hikiwawe e hōʻoia i ka hoʻolako mau ʻana i ka meaʻai o ka ʻōpū;

I kekahi lā ma hope o ka ʻoki ʻana i ka waiu, ua ʻike ʻia ua ʻōpuʻu ka ʻōpū o nā puaʻa, ʻo ia hoʻi, ʻaʻole lākou i ʻike i ka hanai ʻana, no laila pono e hana ʻia nā hana e ʻai koke ai.wai?

No ka hoʻomalu ʻana i ka maʻi maʻi, pono ke koho ʻia nā lāʻau lapaʻau a me nā mea maka;

ʻOi aku ka maikaʻi o ka hopena o nā puaʻa wean a me nā puaʻa nāwaliwali i hānai ʻia me ka hānai mānoanoa ma mua o ka hānai maloʻo.Hiki i ka hānai mānoanoa ke paipai i nā puaʻa e ʻai i ka hikiwawe, hoʻonui i ka ʻai a hoʻemi i ka maʻi maʻi
