Tightening up your calving pattern

For most spring-calving herds,ÌýwhereÌýcowsÌýpredominantly calveÌýduring February, March and April, chances are that cows will now be settled in calf.ÌýMany of you should now be thinking about removing the bull from the cows. With silage and hay making alongside harvest becoming a priority, it is easyÌýfor planned dates to slip and forÌýstockÌýbulls to remain with the cows longer than you had intended.ÌýÌý
If you have not removed bulls yet then now is the time to do so, to put an end to breeding for this season and a definite endÌýto the calving periodÌýnext year. A more compact calving will lessen the workload next spring.ÌýLateÌýcalving cows are always a pain to manage as they areÌýout of syncÌýwith the rest of the herd.ÌýA cow being bulled onÌýthe 15 of August will not calve until the end of MayÌý2027.Ìý
There is often a fear associated withÌýtaking the stock bull away from cows, thinking there will be a high empty rate.ÌýHowever,ÌýifÌýafter 12 weeks of breeding there is a high number of cows empty / not settled in calf this will become clear fromÌýa high levelÌýof activity. Most likely if there are empty cows it may only be one or two which are likely to have either poor fertility or have an underlying condition preventing them from going back in calf which means that if they had run with the bull for another month, they were unlikely to settle in calf.ÌýÌý
A compact calving period offersÌýseveralÌýadvantages for suckler herds and is one of theÌýeasiestÌýwaysÌýofÌýimproving your herdsÌýefficiency and profitability.ÌýA tighter calving pattern results in a more uniform group of calves, making management easier throughout the year. CalvesÌýthatÌýare ofÌýa similarÌýsizeÌýandÌýageÌýat weaning,Ìýare easier managed in terms ofÌýfeeding,ÌývaccinationÌýand marketing.ÌýQuite simply, batches of uniform animals are easier handledÌýand dealt with!ÌýÌý
Older calves at weaning should achieve heavier weaning weights than calvesÌýthat areÌýbornÌýlaterÌýin the season.ÌýIf you are selling weaned calves,Ìýthis then increases the total weight ofÌýanimals produced and gives moreÌýoutput/cow whichÌýultimatelyÌýimprovesÌýthe herd’s overallÌýperformance andÌýprofitability.Ìý
With labour being stretched on farms, having a compact calving period savesÌýonÌýlabour by ensuring most cows calve withinÌýa shortÌýtimeÌýframe. This makes general supervision, calf management, health treatments and feeding moreÌýefficient reducingÌýthe time and labour needed to manage the herd throughout the year.Ìý
Nutritional requirements and rationing for cowsÌýareÌýeasier managed with a compact calving period as cows areÌýmoreÌýlikely to be at a similar stage in gestation and lactation compared withÌýan extended calving period. This makes feeding simpler and more cost effective.ÌýÌý
The herd’s fertility performance is easier toÌýmonitor. Cows thatÌýfail toÌýget back in calf within the defined breeding season can beÌýquicklyÌýidentifiedÌýandÌýpotentially earmarkedÌýfor culling, helping to improveÌýtheÌýherdsÌýfertility.Ìý
If you are finishing your own calves, earlier-born calvesÌýgenerally finishÌýsooner and more efficiently than later-born calvesÌýwithin groups.ÌýThis reduces housing, bedding and feed costs and can improveÌýanimalÌýperformance. Animals being ready to market at similar times are an advantage especially with young bulls who are harder to manage – andÌýcan’tÌýbe easily mixed with other groups when left behind.ÌýÌý
CowsÌýcalvingÌýwithin a defined period also means there is more time between calving and the start of the next breeding season. This allows cowsÌýtimeÌýto recoverÌýtheirÌýbody condition and return toÌýcycling and bulling,Ìýfor the bull going inÌýincreasing the likelihood ofÌýmaintainingÌýtheÌýidealÌý365-day calving interval.ÌýChanges to Scottish Sucker Beef Support SchemeÌý(SSBSS, also known as the calf scheme)Ìýmean that a calving interval of 410 days or less is now required toÌýreceive SSBSS paymentÌý(unless you are claiming less thanÌýtenÌýcalves), so it is hugely important toÌýconsider calving intervalsÌý
In summary, a compact calving period:Ìý
- Produces a more uniform calf crop.Ìý
- Increases weaning weights.ÌýCalves born earlier are heavier at weaning than those later born calves and there is a smaller weaning check in those bigger calves.Ìý
- Reduces labour requirementsÌý-less time supervising an extended calving period andÌýmanagement is easier.Ìý
- Reduces disease risk – less risk of disease spread from older calves to those younger more vulnerable calves.Ìý
- SimplifiesÌýfeeding –Ìýeasier and moreÌýaccurateÌýto ration stock at similar stages of growth,ÌýpregnancyÌýand lactation.ÌýÌý
- Improves herd fertilityÌý– more cows are likely to come into season when the bull is turned out.Ìý
- Can reduce finishing costsÌýwithÌýfinishing cattle are sold earlier.Ìý
- Allows moreÌýeven batches of bigger calves to sell.Ìý
- HelpsÌýmaintainÌýeligibility for the SSBSS scheme.Ìý
