Effects of different glutamine levels on skeleton muscle,small intestine mucous protein,DNA and RNA levels in early-weaned calves

Twelve Chinese Holstein calves with similar weight and age were selected and divided randomly into four groups. They were weaned at 40±1 d. Alanyl-glutamine peptide (Ala-Gln) was supplemented through jugular vein by total parenteral nutrition (TPN), which was used to study the effects of different glutamine levels on skeleton muscle, small intestine mucous protein, DNA and RNA levels in early-weaned calves. The results indicated that mid-glutamine level (0.68 g/kg BW.d) injected 7 d continuously could increased significantly the level of skeleton muscle protein, jejunum DNA and RNA levels in early-weaned Calves(P0.05).
