Nutrisen regulesen teknoloji bilong skruim susu prodaksen long ol susu bulmakau i mas lukluk long eneji balens, protin saplai, rumen helt na mineral na vaitamin suplementesen, wantaim stretpela fiding menesmen long maksimaim susu prodaksen potensial.
Ol dispela em ol ki teknoloji na ol praktikel solusen:
1. Eneji regulesen - stretim hevi bilong negatif balens
Inkrisim eneji konsentresen bilong kaikai
Gol: Daunim negatif eneji balens long eli laktesen taim (0-8 wik bihain long delivery) na daunim tumas mobilisesen bilong bodi gris.
Ol samting bilong skelim: Putim gris long en: gris i save winim mak (olsem kalsium palmitet): 100-300 g/het/de bilong abrusim pasin bilong pasim rumen fermentesen.
Oil bilong ol kaikai (olsem soyabin oil): liklik samting ol i putim ( Lusim o wankain olsem 3% DM) bilong pasim gris bilong susu i go daun i go daun bilong mak bilong susu bilong mi.
Hae stach fid: kon (ol i katem o stim) i akaontem 40%-45%, we i mekem se stach i save daejestibiliti blong daejestibiliti.
Kabohaidret suplementesen: molases (5%-8% DM) i save givim strong hariap na mekim gutpela pasin bilong bel i ken kamap gutpela.
Fes eneji saplai
Peak laktesen taim (2-3 mun bihain long delivery):
Dietari metabolisabel eneji (ME) I winim o wankain olsem 2.75 Makal/kg DM, konsentret akaun bilong 60%{2}}%.
Mid-let laktesen:
Daunim konsentres fid i go long 50%~55% na apim hai-kwaliti rafej (olsem ful kon silage).
2. Stretim protin saplai - optimisim amino asid balens
Balens namel long protin (RDP) na protin-pas protin (RUP)
RDP: 60% ~65% bilong krud protin (CP) (e{2}}'g. kaikai bilong soyabin, urea), na lukautim rumen maikrobial protin sintesis.
RUP: 35%~40% bilong CP (e.'g. kaikai bilong soyabin), i givim ol amino asid bilong kisim liklik intestin i kisim .
Rekomendim kaikai CP level:
Ol bulmakau i gat bikpela gris: ( I moa gutpela o wankain olsem 35 kg milk/de): 16%~18% CP{4}}
Ol bulmakau bilong namel na liklik hap: 14%~16% CP.
Restriktiv amino asid suplementesen
Lysine (Lys) na methionine (Mit):
Rumen-pas lysine: (RP-Lys) 10~15 g/de, rumen-pas methionine: (RP-Met) 5~8 g/de{{8}
Ideal reshio: Lis: Mit ≈ 3:1 (e{2}}}} protin sintesis efisiens i go antap long 5%~8%){6}}
3. Remen helt menesmen - stebol fermentesen envairomen
Fisik fiber (peNDF)
Requirement: peNDF ≥ 20% ~ 22% (DM), maintain rumen motility and pH value (> 6.0).
Source: alfalfa hay (longpela Moa long o wankain olsem 3 cm), ot gras, na ol narapela kain.
Preventim sabakuut asidosis (SARA). Olsem:Busta bilong CJ Acidosis
Yis kalsa
Wok: Promotim planti ol baktiria i save bagarapim ol rop (olsem putim yis kalsa 10 ~ 20 g / het / de).
4. Mineral na ol vaitamin - i mekim wok bilong metabolik i kamap gutpela moa
Ol ki mineral
Kalsium (Ca): 0.7%~1.0% (pasin bilong pasim sik haipokalsemia bihain long karim pikinini).
Fosforas (P): 0.4%~0.5% (retio wantaim kalsium 1.5~2:1).
Ol sol bilong ol anion (21 de paslain long taim bilong karim pikinini):
Spesen bilong Amoniam, magnesium salfet, na ol narapela samting bilong ., stretim DCAD (dietari anion-kasen i narapela kain) i go long -100~{3}} mEq/kg DM long stopim milk fiva{{4}
Vitamin
Vitamin A: 80,000~100,{{3} IU/de (mainten helt bilong mukosal).
Vitamin D: 30,000~50,{{3} IU/de (promotim kalsiam absorpsen).
Vitamin E: 500~1,000 IU/de (antioksidant, daunim hevi bilong mastitis).
5.Aplikasen bilong ol spesel aditiv
Kromium propionet (0.5~2 mg/het/de)
Impruvum glukos metabolism mo inkrisim eneji yutilisesen.
Kolin (rumen baipas)
15~20 g/de, daunim gris leva, skruim susu prodaksen long 3%~5%.
Planim ol essential oil (olsem sinamaldehaid)
Reguletim rumen fermentesen, daunim methane emisen, na kamapim gutpela wok bilong kaikai.
Fomula na yusim bilong CJ i givim susu long pastaim C665 bilong ol bulmakau bilong susu:
Yusim: Miksim wankain wantaim ol narapela samting bilong kaikai long ol dispela mak pastaim long yusim
