Description
| - V měsíčních intervalech po dobu jednoho kalendářního roku byly sledovány skupiny 20 až 23 kusů dojnic českého strakatého plemene, vybraných tak, aby se nacházely v prvních fázích laktace. Dojnice pocházely ze stáda s průměrnou užitkovostí 6 000 kg za laktaci a byly do sledované skupiny vždy vybrány tak, aby se nacházely mezi 20. až 100. dnem po otelení. Celé stádo bylo vazně ustájeno v jedné stáji. Krmná dávka sestávala z krmiv obvyklých v oblasti (kukuřičná a travní siláž, šroty obilovin, extrahované šroty, minerální látky a vitamíny), přičemž jejich množství bylo optimalizováno podle doporučení Somera et al. (1994). Krmiva nebyla krmena formou TMR, produkční směsi byly krmeny v závislosti na užitkovosti. Každý měsíc byla vybrána skupina dojnic, které se nacházely na začátku laktace (20 až 100 dnů po otelení).Dojnicím byla odebrána krev z vena subcutanea abdominis vždy v dopoledních hodinách. V týž den byla po separaci krevní plazmy centrifugací stanovena hladina glukózy fotometricky pomocí Bio-La-t (cs)
- Groups of 20 to 23 dairy Czech Pied cows were observed monthly for the period of 12 months (12 test days). The cows in experimental groups were in their early lactation. The mean number of lactation was 2,8, the cows were on average 54.8 days after calving and the mean glucose concentration in blood plasma was 3.93 mmol/l. During the first 100 days of lactation milk yield amounted to 2581 kg with 3.91% fat, 3.48% protein and 4.85% lactose. The coefficients of the correlation between blood plasma glucose and the observed milk production parameters calculated independently for each test day ranged as follows: -0.597 to 0.130 for number of lactation, -0.389 to 0.585 for days after calving, -0.462 to 0.361 for milk yield, -0.201 to 0.526 for milk fat content, -0.385 to 0.632 for milk protein content and -0.600 to 0.469 for milk lactose content. The calculated coefficients of the correlation between blood plasma glucose and milk production parameters did not reveal a clear tendency in the relationships.
