Analýza výživy a krmení vybraných druhů zvířat v ZOO Brno
Mertová, Magdalena
The thesis is concerned with the issue of nutrition and feeding of animals kept in zoos. Specifically, it focuses on two groups of ungulates kept in Brno Zoo, namely equids (Przewalski's horse, eastern kiang, Chapman's zebra) and ruminants (European elk, Indian takin, Himalayan tahr, reticulated giraffe). The main objective of the work was to verify the suitability of the diets used for the selected animal species in terms of feed used and nutrient composition, using available software. The professional animal nutrition software of AgroKonzulta Žamberk spol. s r.o. and a modified feed database used in the Liberec Zoo were used. Feeding standards were created for individual animal species based on the nutrient requirement standards for livestock. The results of the work show that the available programs are not ideal for the analysis of feed rations of animals kept in the zoo. To improve the analysis, it would be necessary to know the exact nutrient composition of the feed used. The results of the analysis of the diets show that most of them contain too much dry matter and other nutrients (especially crude protein). An exception is the elk ration, which would need to increase the dry matter content while reducing the crude protein content.
