Effect of Supplementing Formaldehyde Treated Rape Seed Meal on Milk Production, Gross Milk Composition, Digestibility of Nutrients and Feed Conversion Efficiency in High Producing Crossbred Cows

Accepted: 13/06/2016 Abstract A study was undertaken to investigate the effect of supplementing formaldehyde treated rape seed meal on milk production, milk composition and feed conversion efficiency. Dietary supplementation of formaldehyde treated rape seed meal had no significant effect on the dry matter intake of cows from different groups. The average milk yield and 4% FCM yield were signif...

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 ...

Effects of grass silage and soybean meal supplementation on milk production and milk fatty acid profiles of grazing dairy cows.

The effects of supplementation with grass silage and replacement of some corn in the concentrate with soybean meal (SBM) on milk production, and milk fatty acid (FA) profiles were evaluated in a replicated 4 x 4 Latin square study using 16 dairy cows grazing pasture composed of ryegrass, Kentucky bluegrass, and white clover. Each experimental period lasted for 3 wk. The 4 dietary treatments wer...
