Frekvence příjmu mléčné krmné směsi v průběhu dne a její vliv na růst u telat českého strakatého skotu
Vozihnojová, Dominika
In this diploma thesis analysis of frequency of milk compound intake during the day and its effect on growth in Czech fleckvieh cattle calves was performed in a large-capacity calf shed Kelčice, which belongs to the agricultural cooperative Určice. The monitoring, which lasted 12 months (from March 2022 to March 2023), included the frequency of daily milk compound intake. The calves were weighed on the day of arrival at the reception pavilion and again on the day of daparture to calf nursery at the end of the milk feeding period. During the monitoring, the temperature (°C) and relative humidity (%) in the calf house were measured using the HOBO sensor. Bulls showed greater weight gain (by 0.06 kg) compared to heifers at the same intake of milk replacer (P < 0.01). The greatest growth was recorded in calves that received an average of 7.1 and more liters of milk replacer (MR) per day (P < 0.01). The effect of the number of feeding days was also observed, when calves achieved greater average daily gain during a longer stay in the reception pavilion (P < 0.01). It was observed that temperatures above 20 °C had a negative effect on the calves, which was shown by the average daily gain, which was the smallest at the highest intake of MR. On the contrary, the temperature of 0-5 °C suited the calves the most when it showed the greatest growth.

KAČÍREK, Pavel
The aim of the bachelor thesis was to monitor and evaluate the growth performance on a family farm in Nový Kostelec. The growth performance evaluation was carried out on a total of 56 Limousin breeding animals. Weighing of each animal was performed at 120, 210 and 365 days of age. When evaluating the growth ability of the bulls, it was found that the highest growth performance of the bulls in the period from birth to 120 days was achieved in 2021, when the average weight of the bulls was 200,36 kg and the average daily gain for the period was 1,286 kg, while the best growth performance in the period from 120 to 210 days was achieved in 2022, when the average weight of the bulls at 210 days was 330,84 kg and the average daily gain since birth was 1,464 kg, in the period from 210 to 365 days the best growth performance of the bulls was achieved in 2022 when the average weight of the bulls was 524,08 kg and the average daily gain for the period was 1,218 kg. The highest average daily gain of bulls since birth was found in 2022 when it was 1,278 kg. In evaluating the growth performance of heifers, it was found that the highest growth performance in the period from birth to 120 days of age was achieved, in 2021, when the average weight was 168,57 kg and the average daily gain for the period was 1,033 kg, while the best growth performance in the period from 120 to 210 days of age was achieved in 2021, when the average weight at 210 days of age was 292 kg and the average daily gain over the period was 1,366 kg, and in the period from 210 days to 365 days of age the best growth performance was found in 2021 when the average weight of the heifers was 420,16 kg and the average daily gain over the period was 0,830 kg. The highest average daily gain from birth for heifers was obtained in 2021 when it reached 1,057 kg.

Porovnání užitkových vlastností mezi plemeny králíků velký světlý stříbřitý a kalifornský
Sysel, Zdeněk
In the literary part, the bachelor thesis deals with the history of rabbit breed-ing and their quantity in the Czech Republic. It is also mentioned classification of breeds based on their weight and the technology used in small-scale and farm breeding. Next part deal with performance, such as growth rate and car-cass yield. In connection with the performance characteristics, rabbit meat and fur production are characterized. The experimental part describes the comparison of performance character-istics of Californian and Great Light Silver breeds in small-scale breeding. Ob-served animals were weighed regularly from 6 weeks old and slaughtered at 18 weeks old. The Great Light Silver breed achieved better daily growth, on aver-age 35.84 g before weaning and 22.25 g after weaning. The highest growth rates in both breeds were observed in the 7-11 weeks of age. After slaughter, the carcass yield was calculated and the carcasses of both breeds were com-pared again. The average slaughter weight of the California breed was 2262 g and the carcass yield was 54%. The Great Light Silver breed was weighed an average slaughter weight of 2777 g and the carcass yield was calculated to be 56%. The Californian breed excelled in the weight balance of individuals regard-less of gender, the VSS breeds females had better growth ability than males.

Moderní trendy ve výživě telat
VLÁŠEK, Pavel
The idea of elaboration of this bachelor thesis was the elaboration of a literature review concerning the development of the morphology of the digestive system of calves, diseases and the method of their breeding and feeding. It also discusses feed additives-probiotics, prebiotics, synbiotics and phytobiotics. The practical part deals with the effect of probiotic additives on health and body growth. A total of 14 calves were included in the experiment, continuously divided into two groups of 7, control and experimental. Both groups were weighed at birth and subsequently every week until the age of 8 weeks. The frequency of diarrheal disease was also monitored during breeding. The results of the experiment show a positive effect of the combination of Lactobacillus sporogenes, Enterococcus faecalis and Bifidobacterium bifidum on reducing the incidence of diarrhea and increasing the average absolute increase, although it was not statistically significant (P>0,05).

Hodnocení růstové schopnosti telat plemene galloway ve vybraném stádě masného skotu
KARAS, Aleš
Object of this thesis was evaluating growth ability of galloway calves in chosen company. Source of dates was KUMP and the observed period was from 2005 to 2020, ie a total of sixteen years. In thesis was observed indicators of growth ability, specifically achieved weight in 120 and 210 days with increments during inspected years per observed period and their comparison between bulls and heifers. Furthermore, the effect on these abilities of each breeding bull, that was active in herd, and effect on number of calved females or their parity. Finally, a comparison of the achieved values in monitored company with the average in Czech Republic. Large differences were found between bulls and heifers, where bulls achieved on average, about of 10 % higher values of gained weight and gain than heifers. A significant effect was also found according to the order of calving, when the growth abilities of calves are improved from the sixth birth, thanks to better milkiness of cows. The effect of breeding bull is quite noticeable, because the biggest difference between the minimum and maximal achieved average weight in 120 and 210 days is 38 kg for heifers and 54 kg for bulls.

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.

Zhodnocení růstové schopnosti telat na vybrané rodinné farmě
Pokorná, Jana
The Bachelor thesis deals with the growth ability of calves at a chosen family farm and it is divided into two parts. In the theoretical part, significance of cattle bree-ding and meat yield indicators are defined, such as the fattening performance of fatted cattle and slaughter value. Furthermore, influences affecting meat yield are described including sex, breeding affiliation, stabling system, nutrition, feeding and other influen-ces. The second part of the work focuses on an experiment pursuing a chosen group of bulls that were given dairy as well as vegetable nutrition, weighted and observed, on the basis of which average daily growths are calculated. At the end of this study, it was found out that the farm achieves very favourable growths. When calves were given dai-ry nutrition, the growth reached 1.83 kg/day and when fattened intensively to gain higher slaughter weight, the growth was about 1.86 kg/day.

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.

Vyhodnocení reprodukčních schopností a růstu potomstva u plemene Masný simentál
Chytka, Vladimír
Beef Simental is a beef breed that is bred almost all over the world. In the Czech Republic there is the third most widespread of meat breeds in the number of cows. Most breeding bulls of this breed act in natural breeding, which confirms its popularity in commercial crosses. This diploma thesis was focused on growth ability and evaluation of reproductive indicators in five breeds dealing with breeding of this breed in performance control. The influence of breeding conditions, sex, breeding method, calving on weight of calf at birth, at 120, 210 and 365 days was monitored. Furthermore, the length of the interim period, the age at the first calving and the order of calving of the cows in the herd of individual breeders were determined. The influence of breeding conditions, breeding method, sex and calving rank was statistically highly significant (p ˂ 0.01). Difference between calves born after insemination bulls and after natural breeding was 25 kg. Bulls had higher weights in all reference periods (120, 210 and 365 days). The difference between the average weight of a bull and a heifer was 146 kg. There was a statistically significant difference (p ˂ 0,01) between the calves from the first calvers and the cows on the second calf and the other calves in weight. The average age at first calving in the evaluated farms is 954 days which confirms the current trend but is in conflict with the breeding goal of this breed.
