Isticmaalka Hydroxy Methionine Calcium 1

1)Digaagga digaagga digaagga ah

Daraasado ayaa muujiyay in xaaladaha kulaylka ee 32 °C, cadaadiska biyaha uu aad u sarreeyo.cusbo kaalshiyam ah oo ka kooban methionine hydroxy analog(HMTBa-Ca) waxay hagaajisaa qaadashada quudinta, celceliska kobaca maalinlaha ah, iyo koritaanka murqaha ee broilers si ka waxtar badan DL-methionine (DLM). Isla mar ahaantaana, waxay si weyn u xoojisaa awoodda antioxidant-ka, waxay yareysaa heerarka xagjirka xorta ah, waxayna hagaajisaa xaaladda redox, taasoo muujinaysa waxqabad sare oo kor u qaadaya hufnaanta wax soo saarka iyo yareynta walbahaarka oksaydhka.

Fiiro gaar ah: DLM waxay tilmaamaysaa DL-methionine, HMTBa-Ca-na waxay tilmaamaysaa cusbada kaalshiyamka ee hydroxy methionine analog. Xarfo kala duwan oo raacaya xogta ku jirta isla tiirka ayaa tilmaamaya kala duwanaansho muhiim ah oo u dhexeeya kooxaha daaweynta (P < 0.05).

2)Doofaar

Daraasaduhu waxay ogaadeen in kaabista cuntada doofaarka lagu daro sideed meelood meel DL-2-hydroxy-4-(methylthio)butanoic acid calcium (HMTBa-Ca) ama 65% qiyaasta DL-methionine (DLM) ay soo saartay horumar la mid ah oo ku yimid waxqabadka koritaanka, labaduba si weyn ayay uga sarreeyaan cuntooyinka methionine-ka ku yar. Ma jirin wax farqi ah oo ka dhex jira kooxaha daaweynta ee qaadashada quudinta ama heerka dhimashada.

Shaxda 1 Jawaabta waxqabadka kobaca ee DL-methionine iyo DL-2 hydroxy-4-methylthio-butyrate oo lagu quudiyo aashitada saamiga 65:100 ee doofaarrada xanaanada.

3)Xoolaha

Lo'da caanaha laga sameeyo ee Holstein, waxaa maalin kasta lagu daraa 400 g oo cusbo kaalshiyam ah oo asiidh dufan leh iyoKaalshiyam hydroxy methioninesi weyn ayay u kordhisay wax soo saarka caanaha iyo wax soo saarka lactose. Lo'da hore, waxay sidoo kale si weyn u wanaajisay waxqabadka taranka, oo ay ku jiraan heerarka rimidda oo sarreeya iyo waqtiyada dhalmada oo gaaban, iyada oo aan saameyn ku yeelan xaaladda jirka ama miisaanka jirka.
