The Breeding season started on Wednesday the 21st of April and 100% AI is being used on the farm again in 2021.
- There are 83 mature cows and 26 maiden heifers for breeding this year on the farm.
- Up to Wednesday 12th of May, 77 cows, or 93% of the 83 mature cows put forward for breeding, have been inseminated in the first 3 weeks of breeding.
- The breeding season will last for 10 weeks and finish on 6th of July.
- Teaser bulls have been fitted with Moocall heat detection along with a chin ball harness for marking the cows.
- Cows have been tail painted yellow for the first round.
- Once a day AI will be used and cows will be inseminated at midday each day.
- If a cow is inseminated at 12 noon and she is still showing signs of standing heat again that evening, that same cow will be AI’d again the next day (12 noon).
- The majority of Newford cows are in an ideal body condition score for breeding.
- The 26 maiden heifers (main picture above) were synchronised on the 13th of April and artificially inseminated on the 21st of April.
- As of 12th of May 9 of these heifers have being inseminated twice
- Mineral buckets are in all paddocks with cows to prevent grass tetany.
- Air temperature is low at night time increasing the risk of ground frost

Sires which will be used on the Newford Herd for 2021 are as follows:
- All the beef animals have being weighed with bullocks weighed on 16th of April and heifers on 28th
- The average weight of the 39 bullocks was 447 Kg
- The average weight of the top 20 bullocks was 480 Kg
- Note: The bullocks were rehoused twice during turnout which hampered early season performance.
- The average weight of the 56 heifers was 444 Kg
- The top 24 heifers averaged 480 Kg
- The weighing performance summary is outlined below;
- Soil temperature on Newford Farm on Monday the 9th of May was 12.4 degrees Celcius at 10 cm soil depth
- Newford farm had almost an inch of rain between last Saturday and Sunday (8th and 9th of May)
- A half bag of protected urea (38N + S) is being spread per acre after each grazing at the moment.
- While the weather is cold and growth is slow, we can expect a sudden burst of growth shortly, so the farm needs to be prepared for this. Therefore a paddock with a heavy grass cover (2,000 Kg/DM ) was taken out of the grazing rotation as surplus grass this week,
- The farm is aiming to keep the grass cover at roughly 650 Kg DM / Ha at this moment and time.
- The aim is to keep turning stock into grass covers of roughly 1,250 to 1,400 Kg /DM /Ha
- Six acres on the home farm was recently reseeded. These two paddocks have being sown with the grass variety Abergain and Aberchoice with clover (Buddy).
- Sowing rate : 12 ½ Kg of grass seed per acre and 1 ½ Kg per acre of clover seed
- It was followed by three bags of 10-10-20 per acre
- All paddocks for first cut pit silage have been closed since 12th of April on Cones farm (17 Ha) while 5 ha has been closed on Tuohy’s farm for first cut bale silage.
