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.
