Dairymac Bray Breeding Calendar Operating Instructions

Choose a well-lit and secure position in the dairy or other adjacent building and fix the calendar on the wall at approximately 6’6” (2.0m) to the top above floor level using the key hole slots provided. The cherry red cursor hand should be set to suit the type of pregnancy testing used; either at 28 days after service where milk sample testing is required or perhaps at 7-8 weeks after service if pregnancy diagnosis is carried out by the vet. Similarly the blue “steam up feeding” hand

BLUE This hand acts as a reminder to prepare for calving or for steam up feeding to begin, as soon as the cow starts to receive extra rations turn symbol to blue and leave in this position until calving when the cycle starts again.

vet calls he should examine and treat this cow for cystic ovary, corpus luteum, etc., so that she may be in fit condition for breeding well before service is due. Any cow whose symbol is still white six weeks after calving should be examined. ORANGE On the day of service the cow’s symbol should be turned to orange and must be placed exactly under the large orange “service” hand. This hand is 283 days away from the white hand and indicates the expected calving date. 21 days after service the small orange hand acts as a reminder to check that the cow has settled. If she returns to bull her symbol will be moved back to under “service” hand also into the inner “first return” ring of the calendar. The return areas act as a valuable early warning since if more than perhaps 30% of the herd gets into this area then the vet should be consulted as a herd breeding problem may be on the way. RED This hand serves as a reminder that pregnancy diagnosis is due. As soon as the cow is confirmed in calf, turn the symbol to cherry red. The symbol of any empty cows must be returned to the green area to await veterinary attention and repeat service. YELLOW The yellow “dry off’ hand indicates that milking should be stopped. As soon, as the cow is dry, turn her symbol to yellow.

should be positioned to suit the season and local routine. Every cow in the herd has its own numbered magnetic symbol with each colour on the symbol and on the calendar turntable having a meaning to indicate a stage in the breeding cycle of the cow. Thus by good herd management we try to get the colours of the symbols to match the colours on the turntable throughout the year. WHITE The white “today’s calving date” hand must be set daily to the correct calendar date. The symbol of any cow calving is placed, white side up, under this hand. GREEN Within the first week or two after calving the cow may be expected to show signs of heat; as soon as this occurs turn her symbol green. At the same time in order to begin recognition of a regular 21 day cycle, move her symbol anti-clockwise (to shorten the “calving index”) and place it exactly opposite the nearest “21 days” green hand. This cow should come bulling again when the next green hand points at her indicating normal healthy activity. But if she came at, say 16 days or 25 days, thus indicating an irregular cycle, her symbol should be moved into the inner “returns” area on the board which is reserved for the shy breeders.
