A trial was conducted with wethers to study the effect of the administration of a synthetic diet (composition: 30.125% starch, 30.125% sucrose, 25% cellulose, 5.25% urea, 8.125% mineral supplement, 1.25% maize oil and 0.125% cholinechloride) upon rumen fermentation. The adaptation to the synthetic diet lasted three months, the proportion of the synthetic diet increasing every week (by 10%) to the detriment of a traditional diet (composition: 0.5 kg meadow hay, 0.3 kg barley, 0.2 kg wheat bran, salt and straw ad libitum). In the 10th week the animals consumed 0.5 kg granular synthetic diet, 0.2 kg cellulose flakes and 0.01 kg polystyrene. After three weeks of the administration of the fully synthetic diet, the rumen fluid was sampled after morning feeding in intervals of 0, 1, 3, 5 and 7 hours. In the dynamics of fermentation, statistically significant differences were found only in isobutyric and isovaleric acid between the 0th and 1st and between the 5th and 7th hours (P less than 0.05--P less than 0.001). The data for all the time intervals were recalculated to average values. These were as follows: total volatile fatty acids 63.03 mmol/l, acetic acid 51.00 mol%, propionic acid 26.75 mol%, butyric acid 19.43 mol%, isobutyric acid 0.91 mol%, isovaleric 1.27 mol%, valeric acid 0.62 mol%, energy efficiency of VFA production 78.23%. The obtained data are confronted with literary data on synthetic diets which contained urea and various energy sources.

Dynamika vybraných biochemických ukazatelů energetického metabolismu u telat pri dvou odlisných způsobech mlécné výzivy
[Dynamics of selected biochemical indicators of energy metabolism in calves fed 2 different types of milk diets]

The effect of two milk diets on the changes in selected parameters of energy metabolism was studied in calves. After the termination of colostrum feeding, the experimental group of calves (n = 10) was given whole milk whereas the calves in the control group (n = 10) were given the Laktosan milk replacer. Blood was collected for biochemical investigation from the third day of age (determination of glucose concentration) and from the fourth week of age (evaluation of the parameters of lipid metabolism). The plasma concentrations of glucose were about the same in both groups of calves throughout the period of study. The total lipid, total cholesterol and triglyceride levels in blood serum were significantly higher in the calves of the experimental group during the milk feeding period; later they did not differ significantly from the values determined in the control calves. On the other hand, the concentrations of non-esterified fatty acids were higher in the calves of the control group in the milk feeding period; the differences, however, are not statistically significant. The average daily weight gains from the 5th to the 18th week of age were significantly higher in the calves given whole milk.

Zdravotný stav a metabolické ukazovatele u teliat napájaných mledzivom a nezrelým mliekom konzervovaným sorbanom draselným a mliecnou kŕmnou zmesou

The aim of the experiments was to investigate the effects of the preservation of colostrum and unripe milk with potassium sorbate at a concentration of 0.5% and of its storage for three to five days at normal environmental temperatures on the calf health condition. A set of 30 calves divided into two groups was included in the trial. Calves belonging to the experimental group were fed preserved colostrum and unripe milk from day 9 to day 30 of their life (the first experimental period), and from day 31 to day 50 (the second experimental period) milk replacer. Calves belonging to the control group were fed milk replacer from day 9 to day 50 of their life. One calf from the experimental group died from a respiratory disease. In the control group, one calf died and another had to be slaughtered; in both cases digestive tract diseases were diagnosed. The number of calves which had to be treated medically was also lower in the experimental group--in the calves fed preserved colostrum--one case of periodic tympany was recorded in comparison with four cases in the control group. When haematological and biochemical characteristics were examined, significantly lower haemoglobin levels were found in experimental calves at the end of the first experimental period (105.4 g.l-1 when compared with 112 g.l-1 in the control group) and significantly higher values of proteinaemia were found in the blood plasma of these calves at the same period (59.6 g.l-1 and 53.8 g.l-1, respectively). Similar differences were also found during a single haematological and biochemical examination.
