Feeding growing and finishing cattle for Better Returns manual - Eblex

Making the most of grassGrazingGrazed grass is potentially the cheapest feed available. To achieve the best potential growth consider:stocking rates, sward, grazing quality and quantity.The use of modern grass varieties along with appropriate types of clover in the sward can bring bigyield benefits as well as reducing nitrogen fertiliser requirements. Target gains at grass depend ontype of stock, available grazing type and length of grazing season. Large-framed cattle turned outat 250-300kg onto good leys with a long grazing season can gain 200kg. Small-framed cattle onmarginal grazing may gain just half this weight.When grazing is insufficient supplementation will be needed:Concentrate supplementationHigh quality forage-based buffer ration• low levels maintain contact with stock • maintains growth rates• higher levels help maintain growth rates • reduces grazing time• does not reduce grazing time • allows grass regrowthFinishing cattle on grassHigh levels of grass quality and quantity must bemaintained for as long as possible to take ‘easyfleshed’ cattle through to finish. Bigger framedcattle struggle to achieve a good finish onpasture alone in summer and autumn. Finisherscan be kept out on full ad-lib finishing feed aslong as ground is dry enough to avoid poachingand there is a dry area to lie down.Keep lot sizes small and move bunkers, troughsand feed trailers regularly to avoid poaching .For finishing cattle, high quality grass silagecan be a digestible fibre source replacing sugarbeet pulp, maize gluten, etc. However, fed athigh levels alongside high starch feeds can resultin loose dung.Alternatively, silage can be made very maturewith a long chop length. Fed in small quantitiesit offers a structural fibre source to keep therumen healthy when high levels of concentratesare fed.SilageFor growing cattle grass should not beallowed to mature beyond 50% ear emergenceat cutting. Feeding silage with straw delaysprogress through the rumen allowing improveddigestion.6
