title: [The use of partly-hydrolyzed straw meal in the feeding of weaned piglets. 3. The concentration of several parameters of protein, fat, carbohydrate and mineral metabolism in the blood serum during the use of rations with different portions of partly-hydrolyzed straw meal].
abstract: Rations containing varied quotas of partly hydrolysed straw meal (PHS) were provided in mixtures of concentrate and straw meal, and selected parameters of the protein, fat, carbohydrate and mineral metabolism were registered in the blood serum at intervals (2nd and 8th week of keeping) in studies with weaned piglets of the country species. In a parallel experiment the straw hydrolysis product was provided without or after neutralization (with CaCO3) in quotas of 5, 10 and 15% in the mixed feed in comparison to the sole feeding of concentrate. Only some out of the total of 16 parameters ascertained in the blood serum showed reactions of the intermediary metabolism in the test groups caused by feeding. In general, straw crude fibre integration decreased the cholesterol level in the blood serum. Urea concentration in the blood decreased with the growing quota of PHS in the feed mixture. Deviations from the norm of various metabolites, which were mainly reflected in the period near weaning (2nd week of keeping) in an increased concentration of free glycerol and urea in the blood serum, could predominantly be registered after the sole feeding of concentrate. On the whole, there were thus certain interactions with growth performance, which clearly advocate the use of quotas of 10% of the hydrolysed straw product in the feed mixture.
