Nzira yekudyisa sei mazai ehuku muzhizha?

Kuve nechokwadi chekuita kwakanaka kwekugadzira mazai muzhizha kana tembiricha yakakwira, zvinodikanwa kuita basa rakanaka rekutungamira.Chokutanga pane zvose, kudyisa kwehuku kunofanira kugadziriswa zvine musoro maererano nemamiriro ezvinhu chaiwo, uye kuchenjerera kunofanira kubhadharwa pakudzivirira kupisa kwekupisa.

Nzira yekudyisa sei mazai ehuku muzhizha?

1. Wedzera huwandu hwekudya kwekudya

Muzhizha, kana tembiricha yepakati ichipfuura 25 ℃, kudyiwa kwehuku kunodzikiswa zvinoenderana.Kudya kwezvinovaka muviri kunodererawo zvichienderana, zvichikonzera kuderera kwekugadzirwa kwezai uye hurombo husina kunaka hwemazai, izvo zvinoda kuwedzera kwekudya kwekudya.

Mumwaka wekushisa kwakanyanya, simba rehuku dzinokandira rinodzikiswa ne0.966 megajoules pakirogiramu yemetabolism yekudya zvichienzaniswa neyakajairwa kudyisa.Nekuda kweizvozvo, dzimwe nyanzvi dzinofunga kuti simba rekudyara rekudya rinofanira kudzikiswa zvakakodzera muzhizha.Nekudaro, simba ndiro kiyi yekuona chiyero chekugadzirwa kwezai mushure me huku dzinokandiravatanga kuisa.Simba risina kukwana rinowanzokonzerwa nekuderedza kudya kwekudya panguva yekupisa kwepamusoro, iyo inokanganisa kugadzirwa kwemazai.

Miedzo yakaratidza kuti chiyero chekugadzirwa kwezai chinogona kuwedzera zvakanyanya kana 1.5% yakabikwa soybean mafuta inowedzerwa kudya panguva yekupisa kwezhizha.Nechikonzero ichi, huwandu hwekudya kwezviyo sechibage hunofanirwa kudzikiswa zvakafanira, kuitira kuti kazhinji husapfuure 50% kusvika 55%, ukuwo kudya kunovaka muviri kunofanirwa kuwedzerwa zvakafanira kuti kuve nechokwadi chekuita kwemaitiro ekugadzira kwayo.

2.Kuwedzera kupiwa kweprotein feed sezvakakodzera

Chete nekuwedzera chiyero cheprotein mune zvekudya sezvakakodzera uye nekuona kuenzana kwemaamino acids tinogona kusangana neprotein inodiwahuku dzinokandira.Kana zvisina kudaro, kugadzirwa kwezai kuchakanganiswa nekuda kweprotein isina kukwana.

Protein yemukati mune feed yehuku dzinokandiramumwaka wekupisa inofanira kuwedzerwa ne1 kusvika ku2 percentage points kana ichienzaniswa nemimwe mwaka, inosvika kudarika 18%.Naizvozvo, zvakakosha kuwedzera huwandu hwekudya kwekeke chikafu senge soya bhinzi uye keke yekotoni kernel mukudya, nehuwandu husiri pasi pe20% kusvika 25%, uye huwandu hwemapuroteni emhuka akadai sehove chikafu. kudzikiswa zvakakodzera kuti iwedzere kunakidza uye kunatsiridza kudya.

3. Shandisa zvinowedzerwa zvekudya zvakanyatsonaka

Kuti udzivise kushushikana uye kuderedzwa kugadzirwa kwezai kunokonzerwa nekupisa kwakanyanya, zvinodikanwa kuwedzera zvimwe zvinowedzera zvine anti-stress athari kune chikafu kana mvura yekunwa.Semuenzaniso, kuwedzera 0.1% kusvika 0.4% vhitamini C uye 0.2% kusvika 0.3% ammonium chloride kumvura yekunwa kunogona kuderedza zvakanyanya kusagadzikana kwekupisa.

4. kushandiswa kwakanaka kwemamineral feed

Mumwaka wekupisa, phosphorus inowanika mukudya inofanira kuwedzerwa zvakakodzera (phosphorus inogona kuita basa mukubvisa kushushikana kwekupisa), nepo calcium iri mukudya kwehuku dzinokandira inogona kuwedzerwa kusvika 3.8% -4% kuti iwane calcium. -Phosphorous balance sezvinobvira, kuchengeta chiyero checalcium-phosphorus pa4:1.

Nekudaro, yakawandisa calcium muchikafu ichakanganisa kunaka.Kuti uwedzere huwandu hwekudya kwekarusiyamu pasina kukanganisa kunakidza kwechikafu chekukandira huku, kunze kwekuwedzera huwandu hwe calcium mukudya, inogona kuwedzerwa zvakasiyana, zvichiita kuti huku dzidye zvakasununguka kuti dziite zvido zvavo zvepanyama.
