Supplementary Feeding of Dairy Cows to Increase Milk Production
Milk production systems in Eastern Australia vary from grazing improved pastures and fodder crops with strategic use of high energy supplements, to feeding complete diets under feedlot conditions. The nature of the production system within any area is dictated by climatic and economic factors. Economic return from milk production within a given area is a function of the genetic capacity of the ...
متن کاملPerformance of lactating dairy cows fed varying levels of total mixed ration and pasture.
Two, 8-week experiments, each using 30 lactating Holstein cows, were conducted to examine performance of animals offered combinations of total mixed ration (TMR) and high-quality pasture. Experiment 1 was initiated in mid October 2004 and Experiment 2 was initiated in late March 2005. Cows were assigned to either a 100% TMR diet (100:00, no access to pasture) or one of the following three formu...
متن کاملAdding liquid feed to a total mixed ration reduces feed sorting behavior and improves productivity of lactating dairy cows.
This study was designed to determine the effect of adding a molasses-based liquid feed (LF) supplement to a total mixed ration (TMR) on the feed sorting behavior and production of dairy cows. Twelve lactating Holstein cows (88.2±19.5 DIM) were exposed, in a crossover design with 21-d periods, to each of 2 treatment diets: 1) control TMR and 2) control TMR with 4.1% dietary dry matter LF added. ...
متن کاملHousing system, milk production, and zero-grazing effects on lameness and leg injury in dairy cows.
The aim of this study was to assess the effect of grazing (G) vs. zero-grazing (ZG), level of milk production, and quality and type of housing system [free stalls (FS) and straw yards (SY)] on the prevalence of lameness and leg injuries in dairy cows. Observations were made on 37 commercial dairy farms across Great Britain. A single visit of 5 d duration was made to each farm. During this visit...
متن کاملThe effect of feeding soybean oil to mid-lactation dairy cows on milk production and composition and on diet digestion
Veira, D. M., Charmley, L. L., Charmley, E. and Lee, A. J. 2001. The effect of feeding soybean oil to mid-lactation dairy cows on milk production and composition and on diet digestion. Can. J. Anim. Sci. 81: 425–428. Mid-lactation Holstein cows were used to test the effect of feeding 3% soybean oil (SBO) on total mixed ration intake, apparent digestibility, milk production, and milk composition...
