Holstein calves, colostrum microbiological, growth intensity


Diarrhea is a common problem on dairy farms, which in turn leads to reduced development of dairy calves. The aim of the study was to assess the influence of colostrum period quality on the health status and development of dairy calves during the first fifteen days of life. The study was carried out under the conditions of 1. zemědělská a. s. Chorušice. 30 calves were included in the study. After birth, female Holstein cattle were randomly divided into three groups with different feeding management practices. During the entire monitoring period, zootechnical parameters were recorded and health status was evaluated. Twelve samples of different colostrum were taken. These samples were subjected to microbiological analysis and the presumed causative agents of diarrheal diseases were identified on the farm. The results showed the influence of colostrum period management on calf development. The  relationship between microbiology and length of  colostrum intake in calves was investigated. With the  right approach to the colostrum period, we can raise healthy and prosperous calves.
