The Old Kladruber horse is the oldest original Czech horse breed – gene resource, with pedigree records spanning three centuries. Because the population is closed, there is a concern about the loss of...
Effects of rearing, sire and calving season on growth and milk efficiency in dairy cows
dairy cows rearing sire
2015/6/1
32 primiparous cows were used. We tested the hypotheses that live weight and milk efficiency were influenced by the system of rearing from the second week of life to weaning, by the sire, and by the s...
