Assessment of the Level of Nutrition and its Relationship to Milk Production in Milk Cows
HORKÝ, Jan
In the ZD Kojčice cooperative farm, a stable in Krasíkovice was studied in 2013 and 2014. The farm's production technology and the quality of the ensiled feed, feeding techniques, composition of the feed portions and selected milk production indicators were examined. The economy of milk production was also assessed. The production of ensilage ensured quality feed that was the basis for the milk cows' feed portions. The results show that the feed portions were well balanced in comparison to the recommended nutritional values for milk cows. The average yield in 2014, unlike 2013, decreased by 146 l to 5 960 l per milk cow per year. The costs per feed day were established at 138,2 Kč. The average costs for one liter of milk were 8,75 Kč/l.

Nutrition of dairy cows in various stages meantime, focusing on assessing the impact of nutrition on milk production and quality
HORKÝ, Jan
This thesis examines the nutrition of dairy cows at various interim phases, with a focus on assessing the impact of nutrition on milk quality and production. At the Kojčice agricultural cooperative in the village of Krasíkovice, I monitored nutrition and production parameters in Czech pied dairy cows over the course of one year. In the first section of the work, I focused on the technique and feeding of the dairy cows, the feed ration, and assessment of the feed itself. The corn silage which they were fed was rated first class. The clover silage was rated as first, second and even third class. Consultation regarding nutrition, feed analyses and composition of daily feed rations was provided by Mikrop Čebín. I also examined the state of health of the dairy cows and calves in relation to nutrition. The average yield was 6,450 kg of milk per cow per year. I monitored the individual components of the milk and evaluated how these changed over the course of the year. The average protein content was 3.48%, while fat was 4.12%. In another section, I evaluated economic indicators of milk production. The average cost per feed day was 143.51 CZK. The average production cost per liter of milk ranged around 8.51 CZK. The average purchase price per liter of milk was 7.65 CZK.
