7.5.7. Developing a Winter Feed Budget

Early planning for winter is a key discipline for beef cattle enterprises in countries with cold winters. This includes planning to have suicient quantity and quality of winter feed on hand for the winter feeding program. To understand the quantity of feed required, a winter feed budget needs to be developed. In its simplest form, a feed budget is used to identify; • The type of cattle to be fed • Number of cattle to be fed • Liveweight at the start of feeding, and target weight at the end of feeding • The number of days that feed will be required to be fed • Rate of feeding e.g. as a percentage of body weight • The feeds to be used. The resulting list of animals, weights, feeds, quality and quantity form the basis of the feed budget Table 7.1. As a part of the preparation of the winter feed budget, planning should also be implemented for a Plan B management option in the event that the preferred winter management system is not able to be implemented for part or all of the planned management period. A completed winter feed budget will then indicate the quantities of each type of feed that is required to be prepared over the spring, summer and autumn 175 Cold Winter Climates Dry Matter in diet Qty Tons in diet Qty Tons in diet Qty Tons in diet Qty Tons in diet Qty Tons A B C D E F G H I J K L M N O P Q R 130 1 st Nov 31 st Dec 60 0.84 200 250 2.75 90 43.4 - - - - - - 10 4.8 1 st Jan 30 th Apr 119 0.84 250 350 2.75 - - - - 30 38.2 50 63.8 20 25.5 175.7 43.4 38.2 63.8 30.3 130 15 th Oct 15 th May 212 0.84 200 350 2.75 - - - - 30 62.5 50 104.2 20 41.7 208.4 62.5 104.2 41.7 in order to feed the cattle under the planned winter management system, and a contingency feed budget Plan B that is required if the preferred strategy is unable to be implemented. The feed budget will generally be prepared on a dry matter basis, thus these quantities will then need to be converted to an ‘as fed’ basis that includes the correction for the moisture content of each of the components of the ration. A contingency for waste and feed spoilage should be added as an additional bufer to the budget. This quantity may be as much as 10 for grain, and up to 25 for hay, silage and haylage. Table 7.1.

Finishing Beef Cattle A RELATIVELY SMALL NUMBER OF LIVE CATTLE ARE EXPORTED to cold climate countries as feeder steers. However, management of locally-bred feeder cattle is increasing in these countries as a result of a signiicant focus on developing local beef industries. The importation of feeder steers increases the recognition of the beef breeds being used and improves the quality of beef produced for both domestic and export markets. Cattle inishing is generally a two-stage process known as i Backgrounding, and ii Finishing. These two phases accommodate the progressive changes in growth that
