The aim of this research was the detection of Carnosine (Carn) and l-Histidine (l- Hist) in goat milk and blood plasma of two different farms. The Farm T raised racially mixed goats instead the Farm S the pure race Chamoised of the Alps. The mean value ± S.E. (nmol/ml) in milk of Farm T: Carn (19,74±7,48) ed l-Hist (33,44±7,94) and in Farm S: Carn (15,45±4,01) and l-Hist (59,87±2,19); significant higher levels of l-Hist was found in Farm S (p<0,05).The mean value ± S.E. (nmol/ml) in plasma of Farm T: Carn (65,14±7,52) and l-Hist (177,70±14,34) and in Farm S: Carn (40,57±5,46) and l-Hist (187,59±18,12); significant higher levels of Carn was found in Farm T (p<0,01). In both the Farm there were significant differences (p<0,001) for Carn and l-Hist between milk and plasma. In Farm S there was a constant distribution of Carn and l-Hist in both compartment: l-Hist 82%- Carn 18% in plasma and l-Hist 81%-Carn 19% in milk, instead in Farm T l-Hist 73%-Carn 27% in plasma and l-Hist 63%-Carn 37% in milk. These data shows a different distribution in Farm T between milk and plasma of these two molecules instead there were constant in Chamoised Farm; this could be due to homogeneity of goat. The higher concentration of l-Hist in milk of Chamoised Farm could be index of a best quality of product, because this molecule is considered limiting the production of milk proteins.

Abstract
The aim of this research was the detection of Carnosine (Carn) and l-Histidine (l- Hist) in goat milk and blood plasma of two different farms. The Farm T raised racially mixed goats instead the Farm S the pure race Chamoised of the Alps. The mean value ± S.E. (nmol/ml) in milk of Farm T: Carn (19,74±7,48) ed l-Hist (33,44±7,94) and in Farm S: Carn (15,45±4,01) and l-Hist (59,87±2,19); significant higher levels of l-Hist was found in Farm S (p<0,05).The mean value ± S.E. (nmol/ml) in plasma of Farm T: Carn (65,14±7,52) and l-Hist (177,70±14,34) and in Farm S: Carn (40,57±5,46) and l-Hist (187,59±18,12); significant higher levels of Carn was found in Farm T (p<0,01). In both the Farm there were significant differences (p<0,001) for Carn and l-Hist between milk and plasma. In Farm S there was a constant distribution of Carn and l-Hist in both compartment: l-Hist 82%- Carn 18% in plasma and l-Hist 81%-Carn 19% in milk, instead in Farm T l-Hist 73%-Carn 27% in plasma and l-Hist 63%-Carn 37% in milk. These data shows a different distribution in Farm T between milk and plasma of these two molecules instead there were constant in Chamoised Farm; this could be due to homogeneity of goat. The higher concentration of l-Hist in milk of Chamoised Farm could be index of a best quality of product, because this molecule is considered limiting the production of milk proteins.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
