    Influenza esercitata dal tasso lipidico del latte su alcune caratteristiche chimiche ed organolettiche delle carni e del grasso di vitelli a “carne bianca”

    No full text
    L'insieme dei risultati ottenuti su vitelli a carne "bianca" consente di affermare che l'utilizzazione di latti a più elevato contenuto lipidico migliora la qualità delle carni favorendone un aumento della sostanza secca e del contenuto proteico; il muscolo inoltre si presenta più chiaro e -di conseguenza- più apprezzato dal consumatore di carne di vitello

    Three groups of 12 sows (high-productivity Goland hybrids) were fed from the 106thday of gestation to the end of lactation (27 ± 3 d) one of 3 diets: Cl, LP,, LPS, (experiment 1). Thediets differed in protein levels (CP (%DM): 16.7; 13.4; 14.1, respectively) and amino-acid content(lysine (%DM): 0.87; 0.48; 0.86; methionine + cystine (%DM): 0.57; 0.42; 0.56; threonine (%DM):0.70; 0.53; 0.53; tryptophan (%DM): 0.20; 0.12; 0.20). In a second experiment, 4 groups of 11 sowswere fed one of 4 diets (experiment 2): ,2C L,2P LPPS, L 2PS (CP (%DM): 17.2; 11.9; 13.3; 13.6,respectively; lysine (%DM): 0.77; 0.39; 0.54; 0.76; methionine + cystine (%DM): 0.59; 0.45; 0.52;0.55; threonine (%DM): 0.67; 0.45; 0.56; 0.66; tryptophan (%DM): 0.20; 0.12; 0.17; 0.20,respectively). The LPS, diet was supplemented with the synthetic amino acids, lysine, methionine,tryptophan, and LPPS and LPS2 were also supplemented with threonine. The different diets had nosignificant effects on sow performance and litter productivity. Low-protein and amino-acidsupplementeddiets significantly reduced both blood (experiment 1: C! 30.3; LP, 28.0; LPS, 22.1mg/dl; experiment 2: 2C 36.5; L 2P 31.4; LPPS 30.8; L 2PS 21.3 mg/dl) and milk urea values(experiment 2: 2C 20; L 2P 13; LPPS 9; L 2PS 10 mg/dl), which indicates a reduction in proteincatabolism
