The aim of the thesis was to evaluate the feed ration of sport horses on the farm Elevage The Field in Switzerland. A total of 18 horses of various breed, age and workload were selected for evaluation. Their workload and daily food intake were recorded for five months. This period was divided into two periods (from February to April and from May to July). Horses were divided into two categories, namely the group of working horses and the group of horses without a workload (young and convalescent horses). Condition of both groups of horses was evaluated according to (BCS). Further, the need for nutrients was determined and the calculation of feed rations was performed according to the standards of NRC (2012) and Zeman et al. (2005). Both standards were then compared with each other. After that the adequacy of dry matter, SEk, NL (SNLk), fat and fiber intake was assessed . It was found that the technique of feeding and the way of breeding mostly meet the needs of sport horses. Based on the comparison of needed and received nutrients, it was found that the dry matter, fat and fiber intake is adequate for both groups of horses. However, most rated horses recieved more of SEk and NL (SNLk) than their daily need. Both used standards can be considered comparable in calculation of SEk; in terms of content of NL (SNLk) there are some differences. The standard by Zeman et al. (2005) is much stricter in this regard.

This thesis deals with the use of hulless barley KM 1057-1906 in poultry feed. This type of barley is characterized by reduced fiber content and a reduced content of beta-glucans. Experiment was performed on male experimental chicken hybrid combination ROSS 308. ROSS chicken were divided into groups and fed izonitrogenous diet containing 30 % and 60 % of hulless barley. The control group was feeding by wheat, which was in diet in 30 % and 60 %. Weight gain, feed intake, feed conversion ratio were monitored and carcass yield was observed in all chickens post-mortem. We fed this diet from day 20, so the conclusions and recommendations can be used only for this period. The influence of hulless barley KM 1057-1906 on fattened broilers was not significant. In other words, the experiment confirmed the theory of impropriety inclusion of barley in diets of poultry and this may be used without major economic losses, for example, used in organic farming.

The topic of this diploma work was to evaluate the hematological and biochemical indicators of various breeds of dogs. The aim of this work was to evaluate the blood samples taken from 10 dogs and 10 bitches of various breeds and find out the dependency of values in relation to their age, nutrition and sex. The samples were processed and evaluated from May to October 2015. The following was examined from the hematological indicators: RBC, HGB, HCT, MCV, WBC and a blood smear was made, from which a differential count of leucocytes was made. Furthermore, the following biochemical indicators were examined: TP, GLU, CHOL and ATP. The literature research first focused on the basic components of dog feed. Moreover, the hematological and biochemical indicators of blood as well as the methodology of the whole experiment were described. The results were processed with the aid of the RStudio program and the following basic statistical characteristics were counted: median, minimum, maximum and standard deviation. The ANOVA statistical method was used, in which the dependency of values among sex, age category and the type of feed fed to the animals was determined. Furthermore, the values among the breeds were compared. From the differences observed among the breeds, there was an increase in red blood cells in German Shepherds and Dobermans. Dobermans, Labrador Retrievers and German shepherd crossbreeds had increased values of ALT. Significant findings showed that there was an increase in the number of red blood cells and hematocrits in subjects fed with granulated feed as opposed to subjects with a combined diet. The difference was also observed for MCV between the genders. Differences between the genders were found for ALT values. More data would be needed to confirm the relationship to age. ALT values are dependent on the type of feed, where the values are higher in subjects fed with a completely granulated diet. The values of total protein increased in dogs with age. This trend is likely to be observed in bitches. For subjects fed a combined diet (granulated feed + home diet) an increase in the value of total protein was observed with age. For subjects fed granulated feed, this increase was not as significant.
