Practical Experiences to Improve Suckler Herd Fertility
26th October 2011
William Johnston, CAFRE Beef and Sheep Development Adviser discussing this year's breeding season with Ralph Lyons, Eskra
By William Johnston CAFRE Beef and Sheep Development Adviser
Ralph Lyons from Eskra has a 60 cow Suckler herd with an average Calving index of 377 days compared to the NI average of 400 days.
I asked Ralph what was his secret to getting herd fertility right year on year. His answer included –
Using an easy calving bull – The BLUP data for the Charolais stock bull indicates that calving difficulty should not be a problem and this has been Ralph’s experience. Difficult calving’s can result in womb infections, slower return to cycling, depressed intake in the cow, dead calves and destroyed cows.
Maintaining Cow Condition Post calving - Concentrates are fed to early spring calved cows prior to turnout. This is an additional cost but the benefits in terms of improved fertility justify the expense. Silage only diets will not supply enough energy no matter how much is offered.
Cows whose condition score has dropped to under 2 will be very difficult to put back in calf and it can be difficult to improve the condition of milking cows.
Controlling Diseases which affect Herd Fertility – Ralph vaccinates his cows, prior to the breeding period, for BVD and Leptospirosis. Both diseases affect reproductive efficiency and can cause foetal death and abortion.
Monitoring Reproductive Performance – A breeding diary is used to record calving dates, service dates and pregnancy diagnoses. Although all cows are bred by natural service the bull does not run with the cows in the shed. Good records allow Ralph to review breeding activity and take action where necessary. The breeding period starts on the 12thMarch and the first scanning usually takes place towards the end of April. This ensures that only pregnant cows are put to land further away from the yard.
Paying Attention to Detail – Ralph also listed other practices such as feeding pre and post calving minerals, having repeat breeders and any cows with white discharges checked by the vet and using gloves when examining cows at calving.
Achieving good reproductive performance in a suckler herd isn’t easy. However by identifying the main factors listed above and adjusting herd management accordingly should lead, to a lower Calving Index and improved herd profitability.
