Použití různých mléčných krmných směsí ve výživě telat
Divišová, Markéta
The aim of this diploma thesis is to evaluate the weight, hip height differences, and the occurrence of diarrhea in calves, which were fed with various milk compound feed. The experiment was conducted on 26 Holstein calves divided into 2 groups (n = 13). The control group was fed by milk compound feed Startino (Sano) and the experimental group with milk compound feed LilaCitro (Sano). The control compound feed was a skimmed milk type and the experimental compound feed was a whey type. Feeding went on the identical schedule. The experimental compound feed was used from the 3rd week as at this age, the calf is able to digest whey. In evaluated parameters (weight, gain, hip height, diarrhea occurrence), there were not found any statistically significant differences between the groups (p>0,05). The economical aspect of different feeding compounds was evaluated as well. The overall expenses of milk compound feed of the experimental group are 1 652,02 CZK lower than those of the control group. Given that we did not find out any statistically significant differences in weight, hip height, and diarrhea occurrence but there is the evident difference in the expenses of compound feed, it is feasible to recommend and use cheaper milk compound feed of whey type.

Porovnání různých způsobů odchovu telat v období mléčné výživy u holštýnského skotu
Adámek, Jiří
The bachelor's thesis deals with the comparison of different methods of rearing Holstein calves in the period of milk feeding. The research was carried out in the Mír Agricultural Cooperative with headquarters in Ratiboř and on farms in Pržno and Hošťálková. On farm in Pržno, the calves are housed in a group pen with milk feeding machines Urban Alma Pro. On the farm in Hošťálková, it is the most common for the calves to be housed in individual outdoor sheds. Thesis compares the weight of calves at birth, the weight of calves at weaning and the average daily gain compering individual farms. Furthermore, the consumption of milk feed mixture is measured in the Urban Alma Pro system on a farm in Pržno. Based on my own findings, I can state that on the farm in Pržno the weight of calves at birth was lower also the weight of calves at weaning and the average daily gain was higher than on the farm in Hošťálková. The average consumption of the milk feed mixture using the Urban Alma Pro system was lower compared to the optimal average consumption. This could be caused by unfamiliarity of the new environment and possible diseases contracted by calves. The rearing of calves on the farm in Pržno was therefore more efficient for agricultural production, more beneficial from the health point of view of the calves, less financially demanding and more natural for the calves thanks to the Urban Alma Pro system. The main advantage is the possibility of drinking the milk mixture six times a day in smaller doses. In the normal rearing of calves on the farm in Hošťálková, it is at best possible to feed the calves with milk feed mixture only twice a day.

Výživa telat v období do odstavu
Sladký, David
Nowadays, the topic of calf nutrition in the weaning period is increasingly discussed. The theoretical part of the bachelor thesis describes the period of colostrum, milk and starter nutrition and weaning of calves. Furthermore, an overview of the feeds used in calves during the lactation period is presented, focusing on colostrum, milk replacers, starter feeds and drinking water. In the practical part, the results of a trial of feeding dairy compound feeds from two different producers are described. 20 calves were included in the trial and divided into two groups and after the lactation period, ten of them were fed with Multimilk Vital from VVS Verměřovice and the other group with Telfid Extra from FIDES AGRO, s. All calves were monitored for weight, health, consumption of starter mixture and gains were calculated and an economic evaluation of the cost of rearing calves was carried out. No statistically significant differences were found in live weight of calves, daily gains or consumption of starter mixture throughout the experiment. At one stage of rearing, a higher incidence of diarrhoea was found in calves fed Telfid Extra. Although the final evaluation of the increments showed almost identical results, after recalculation of the economic aspect, Telfid Extra with a cost of 47.57 CZK per kg of increment was more economical than the Multimilk Vital mixture, where the cost per kg of increment in the feed used was calculated at 58.02 CZK.

The breeding management of piglets with low birth weight leading to a lower mortality rate.
ŘEZÁČ, Ivan
The aim of the first experiment was to verify the effectiveness and profitability of providing of supplemental feed to piglets. Milk feed mixture of two producers (MFM- 1 vs MFM-2) were evaluated (served ad-libitum). All piglets were suckled and were fed with the pre-starter feed mixture from the 5th day until the weaning stage. The control group without milk supplements has shown a higher piglet mortality and worse body condition of sows. The usage of milk supplements led to the elimination of the sows´ body condition loss during the suckling period and reduced feed mixture consumption in sows (P<0.05). The MFM-1 group was found to have a higher consumption of milk supplement, the lowest mortality and the lowest loss of sows´ body condition (P<0.05). However, from the economic point of view, i.e. the costs on 1 weaned pig, slightly better results have been proven at the MFM-2 milk feed mixture. In the second experiment sows were divided into 2 groups. In the first group, the piglets were fed with milk feed mixture and in the second group, nurse sows (15% of the herd) were used. Nurse sows had a longer suckling period and farrowing interval, a slightly lower number of litters per sow per year and by 0.93 lower number weaning piglets per year. Using the milk feed mixture, generated a higher business profit per year than for nurse sows. However, the fact that nurse sows block the farrowing pen should be taken into account. In case there were kept sows fewer, the business profit would be higher. The aim of the third experiment was to compare 5 trials performed with two different pre-starter feed mixture for piglets and different feeding techniques in sow farrowing house. The relationship between the number of weaned piglets and their live weight in relation to the price of the nutritional supplement has not been not proven. Feeding piglets both with the sow's milk and starter feed mixture or milk feed mixture during the day would have a positive effect on their weight. Very important part of the post- weaning period is to make sure that the piglets are able to digest the subsequent feed mixture (so-called "enzymatic training"). Further research is needed to prove the effect of individual feeds on average daily gain, piglet mortality and the economic efficiency of piglet rearing.

Vliv způsobu odchovu telat holštýnského plemene skotu na jejich další růstovou schopnost
Čunderle, Jan
The submitted bachelor thesis aims to analyze and evaluate the effect of method of rearing calves holstein breed of cattle on their growth ability. Monitoring was conducted for 24 pieces of calves heifers of holstein breed, in two repetitions in different seasons (spring and fall). One half of the calves were fed with native milk and other milk replacers. Monitoring was repeated by weighing in seven-day intervals. The resulting values of the gains for calves on milk replacers are an average of 0.79 kg/day (1. the period of 0.81 kg/day, 2. the period of 0.77 kg/day), in native milk are the average gains of 0.76 kg/day (1. the period of 0.83 kg/day, 2. the period of 0.69 kg/day). From the detected results, it is shown the minimum difference in the performance of rearing.

Odchov telat s použitím různých dávek mléka
Paulíčková, Michaela
The aim of the thesis was to compare the effect of feeding calves with different doses of milk on their health condition, weight and weight increment, consistency of faeces, blood parameters and the effect of plant nutrition. The experiment was carried out with 2 groups of calves (n = 30), the first group (experimental) was fed with 6 liters of milk per day and the second group (control) with 10 liters of milk per day. Calves were fed twice a day and had drinking water and starter all the time. Calves were fed with colostrum within 2 hours of delivery and were on colostrum nutrition for 3 days, the fourth day they were included in the experiment, they were weighed and converted to the milk feed mixture. The second weighing was done at the end of the experiment at the age of 38 days. The third weighing was done at the age of 155 days, when the calves were on plant nutrition. The average birth weight of all calves was 33,5 kg. The final weight was statistically significantly lower in the experimental group, the average final weight was 57.8 kg and in the control group 65.9 kg. The mean total weight increase in the experimental group was 26.4 kg and in the control group 30.3 kg. The intake of starter was statistically significantly higher in the experimental group. The experimental group had a better evaluation of faeces consistency. On the second blood collection, the experimental group had a blood ?-glutamyltransferase level over the reference range, and it was 0,62 µkat/l and the difference between the experimental and control group was statistically demonstrated. Statistically significant was the higher albumin level in the control group at the second blood collection. The results of the experiment clearly do not show a better or worse effect of feeding different doses of milk during the milk diet, higher doses of milk provided higher weight increase during the milk diet, which means higher economic costs.
