Valine(Val) yog ib qho tseem ceeb amino acid rau npua, thiab nws kuj yog ib tug ceg ntoo - saw amino acid uas tseem ceeb lom functions. Kev nkag siab tob hauv -Kev nkag siab tob txog qhov xav tau ntawm Valine rau npua ntawm ntau theem yog qhov tseem ceeb rau kev tshawb fawb noj zaub mov thiab tsim cov npua.
Vim li cas Valine tseem ceeb rau npua?
Nrog rau lysine, threonine, methionine thiab tryptophan, Valine yog ib qho khoom noj khoom haus tsis tseem ceeb rau npua. Val supplementation ua tau zoo txhim kho npua kev ua haujlwm thaum noj cov protein ntau tau txo los ntawm ntau dua 3 feem pua. Tsiaj txhu tsis tuaj yeem tsim Val thiab yuav tsum tau txais nws txaus los ntawm kev noj zaub mov kom tau raws li lawv cov kev xav tau. Ntxiv nrog rau kev siv cov protein synthesis, Nws yog ib qho tseem ceeb rau tsiaj loj hlob thiab kev loj hlob. Nws tuaj yeem oxidized los muab lub zog thaum lub sijhawm tshwj xeeb ntawm lub cev; nws tuaj yeem tswj cov protein hloov pauv ntawm cov leeg pob txha; nws tuaj yeem txhim kho lactation kev ua tau zoo ntawm sows; nws tuaj yeem cuam tshuam rau kev tiv thaiv kab mob ntawm npua.
Valine Function rau npua ntawm ntau theem
1. lactating sows
Valine is of great significance for improving the lactation performance of sows. Valine is the fifth limiting amino acid for pigs. It is of great importance for the growth and development of mammary glands. The addition to the diet of lactating sows can increase the plasma alanine concentration first and then decrease it. This suggests that high concentrations of Valine can stimulate the production of alanine. It fulfills the demand for glucose in the mammary gland tissue, thereby increasing the sow's milk production.
2. cov npua tsis tau
Kev tshem tawm ntxov tuaj yeem ua rau muaj teeb meem xws li kev loj hlob stunted. Ntxiv cov amino acids thiab lwm cov as-ham rau pub tuaj yeem txo qhov kev ntxhov siab ntawm piglets rau qee yam. Valine muaj physiological functions xws li oxidative zog mov, txhawb protein synthesis, thiab txhawb gluconeogenesis. Nws tuaj yeem txhim kho qhov ciaj sia ntawm cov piglets weaned thiab txhawb kev loj hlob thiab kev loj hlob ntawm weaned piglets.
Cov ntsiab lus
Hauv kev lag luam pub khoom noj muaj kev sib tw, txo cov nqi tsim khoom los ntawm kev siv tshuab yog ib qho kev txhawj xeeb tseem ceeb ntawm kev lag luam. Tsis muaj Valine hauv kev noj haus tuaj yeem cuam tshuam rau kev loj hlob ntawm npua. Hauv kev tsim khoom, kev siv lub ntsiab lus tuaj yeem txhim kho cov txiaj ntsig kev lag luam. Pub-qibValine can be added to meet pigs' needs while reducing adverse effects on pigs and the environment when formulating low-protein diets.
