Ration Balancing : New Advances in Dairy Research
ثبت نشده
چکیده
As advances in dairy cattle nutrition research are now becoming available to the dairy industry, it is sometimes difficult to understand how these differ ent advances and improvements in our understanding of dairy nutrition with the different approaches taken by different companies and their associated “jargon”. This brochure is meant as a general overview of the different ration balancing systems that ar e available to Ontario dairy producers and the level of our understanding and use can be for each one.

متن کاملEconomic Evaluation of Dairy Feeds
Feed costs typically represent more than 50% of total costs of producing milk on a dairy farm. Feed cost savings, even a few dollars per ton, add up to significant savings over a year on a large dairy. For many dairies, a ration-balancing software program that uses linear programming techniques can be used to determine the opportunity cost or price of including a new feed in a ration. However, ...
متن کاملNIRS: Forage analysis and livestock feeding
This paper describes analysis by near infrared reflectance spectroscopy (NIRS) and demonstrates the capacity of this technology to provide rapid, low cost and accurate estimates of feed composition. The need for an extensive database against which the instruments is calibrated and the importance of good wet chemistry backup to NIRS are emphasised, together with some of the diverse uses for NIRS...
متن کاملPredicting ad libitum dry matter intake and yields of Jersey cows.
Two data files were used that contained weekly mean values for ad libitum DMI of lactating Jersey cows along with appropriate cow, ration, and environmental traits for predicting DMI. One data file (n = 666) was used to develop prediction equations for DMI because that file represented a number of separate experiments and contained more diversity in potential predictors, especially those relate...
