Kev noj haus cov kev noj haus los ntawm kev cai siv tshuab los ua kom muaj kev siv mis nyuj sib xyaw ua ke, sib xyaw ua ke nrog cov mis nyuj sib xyaw ua ke kom muaj peev xwm pub mis rau ntau tshaj
Hauv qab no yog cov thev naus laus zis thiab cov kev daws teeb meem:
1. Kev tswj hluav taws xob kev cai - daws cov teeb meem ntawm qhov tsis zoo
Nce lub zog ntawm cov khoom noj
Lub hom phiaj: unceviate lub zog tsis zoo nyob rau lub sijhawm lactation thaum ntxov ({} lub lis piam tom qab xa tawm ntawm lub cev rog {}}
Kev Ntsuas: Ntxiv cov rog: rumen-dhau rog (xws li calcium palmitate): {} g / taub hau / hnub kom tsis txhob muaj rumen fermiting.
Cov roj zaub (xws li roj taum): tsis pub ntxiv (tsawg dua lossis sib npaug nrog rau kev poob qis ntawm cov rog rog rog.
Cov hmoov txhuv nplej siab: Pob kws (cov pob kws sib tsoo lossis ua yeeb nkab
Carbohydrate ntxiv: Zib suab thaj (5%-8}}}}}}}}}}}}} Tshaj lub zog thiab txhim kho palatability.
Kev Siv Hluav Taws Xob Hluav Taws Xob
Lub sijhawm lactation (2-3 lub hlis tom qab xa khoom):
Kev noj haus metricolizable zog (kuv) ntau dua los yog sib npaug rau 2 .}}}}} {{{{%.
Mid-lig lactation:
Txo cov pub rau kev pub rau 50% ~ 55% thiab nce cov rougage zoo (xws li tag nrho cov pob kws silage)}
2.} precise protein muab - optimizing amino acid tshuav
Sib npaug ntawm rumen-degradable Protein (RDP) thiab Rumen-Pass Protein (RUP)
RDP: 60% ~ 65% ntawm cov protein crein (CP) (e {{{}}} {), tswj kev rumen microbial {{4}
RUP: 35% ~ 40% ntawm cp (e . g} rumen-pass {.
Pom zoo rau kev noj zaub mov CP theem:
High-yielding nyuj: (ntau dua lossis sib npaug zos rau 35 kg Mis nyuj / hnub): 16% ~ 18% CP {}}}
Nruab nrab thiab qis-yielding nyuj: 14% ~ 16% cp .
Txwv tsis pub Amino acid ntxiv
Lysine (LYS) thiab Methionine (tau ntsib):
Rumen-Pass Lysine: (RP-LYS) 10 ~ 15 g / hnub, rumen-pass methenine: (rp-ntsib) 5 ~ 8 g /.
Cov Lus Zoo Tshaj: LYS: ntsib ≈ 3: 1 (e {{}}}}}}} {%) .
{{0 {}} Kev Tswj Xyuas Kev Noj Qab Haus Huv - Qhov chaw ua haujlwm ruaj khov
Lub cev siv fiber ntau (Pendf)
Requirement: peNDF ≥ 20% ~ 22% (DM), maintain rumen motility and pH value (> 6.0).
Tau qhov twg los: Alfalfa Nyab (ntev ntau dua lossis sib npaug zos rau 3 cm), oat nyom, thiab lwm yam.
Tiv thaiv kom tsis txhob muaj acidos tsho acidosis (Sara) . Piv txwv:CJ Acidosis Buster
Poov xab kab lis kev cai
Muaj nuj nqi: txhawb nqa cov kab mob fiber ntau ntawm cov kab mob fiber ntau (xws li ntxiv cov poov xab kab lis kev cai 10 ~ 20 g / Taub hau) {3} {3}
{{04. minerals thiab vitamins - txhim kho metabicolic efficiency
Cov Minerals Tseem Ceeb
Calcium (Ca): 0 .}} 7% ~ 1.0% (tiv thaiv kev postpartum hypocalum hypocalum hypocalcemia).
Phosphorus (p): 0 . 4% ~ 0.5% (piv nrog calcium 1.5 ~ 2: 1).
Cov ntsev ntsev (21 hnub ua ntej xa khoom):
Ammonium chloride, Magnesium sulfate, thiab lwm yam} met} Kuv yog tus ua npaws kub taub hau}}}
Cov vitamins
Vitamin A: 80, {{000 ~ 100, {}}}}} {.
Vitamin D: 30, 000} ~ 50}}}}}}}}} .
Vitamin E: 500 ~ 1, 000 iu / day (antioxidant, txo txoj kev pheej hmoo ntawm mastitis).
5. Daim ntawv thov ntawm tshwj xeeb ntxiv
Chromium propionate (0.5 ~ 2 mg / taub hau / hnub)
Txhim kho cov metabolism txhim kho thiab nce lub zog siv hluav taws xob .
Choline (rumen bypass)
15 ~ 20 g / day, txo cov mis nyuj rog, nce cov mis nyuj ntau lawm los ntawm 3% ~ 5% {4 4}}
Cov roj tseem ceeb (xws li zoo li cinnamaldehyde)
Tswj hwm rumen fermentation, txo cov methance emissions, thiab txhim kho pub noj kev ua haujlwm .
Pom zoo cov mis thiab siv tau ntawm CJ Lactating Premix C665 rau cov mis nyuj mis nyuj:

NCO TSEG: Nws raug nquahu tias cov thawj coj ua ntej rau 2}}}} Nws raug pom zoo tias cov kev sib xyaw ua ke ntxiv rau 40% ntawm tag nrho cov kev sib xyaw (qhuav teeb meem 88%).
