Being aware of the impact of lameness on milk production is necessary to encourage farmers to pay more attention to this issue. Therefore, we need evidence that presents the production loss due to lameness. This can be applied to make the farmers realize the importance of lameness. This study aims to examine the impact of lameness on daily milk yield based on data obtained from cow level in a large dairy farm with 2 units in Thailand. The crossbred Holstein Friesian cows were evaluated for the degree of lameness by locomotion score (LS) monthly for 8 consecutive months. Cows were …

The goal of this study was to identify the correlation between milk yield and milk malondialdehyde (MDA), an oxidative stress marker. The study was conducted using cows from eight small-holder dairy farms during October to December 2004. The data comprised of sample date, milk yield, and the recent calving date were recorded. Morning milk samples were collected monthly for the measurement of somatic cell counts (SCC) and MDA level using the automate counter and the modified Smith’s method, respectively. The final data set included 131 milk data from 74 cows. Overall means and SEM of milk yields, somatic cell scores …

The goal of this study was to generate production indicies for evaluating cow and farm production efficiency. The milk yields from cows on 10 farms in the Khonkaen province were recorded. The data were transformed into a value depicting standard milk production and subsequently calculated to show the average standard milk production of each farm and an average for all farms. These data were used to calculate 2 production indecies: 1) a cow production index, calculated by dividing the cow standard milk production figure with the average standard milk production for the farm, and 2) a herd production index, calculated …
