  • Client with Winter and Spring milk production has to reduce protein in cows diets.

    Morning rise and time first call of the day was down to Timoleague in West Cork. Visited a client with Winter and Spring milk production systems in Barryroe Co-op area which is 4% over quota and as a result he has had to reduce the level of protein in the diet. This has maintained BCS in the cows and at the same time reduced the flow of milk. He will need to reduce cow numbers in the coming year by the order of 20% as the risk of the quota situation is far too great. What has saved him in this current year is extra quota.

  • Scanning cows for embryo transfer

    Visited a farm today in County Down where a herd of cows was presented for scanning including 35 maiden heifers. The client wanted to identify suitable recipients for Embryo transfer. The client has two sons which are very interested in the breeding of cattle. As is the norm in the breeding of black and white Holsteins, with the possibility of having some red and white cattle in the herd. This family purchased 13 embryos from one of the best red and white Holstein cows in America. The embryos cost between £800 and £1,000 pounds each. With such an investment , they needed to identify the best recipients available. We use scanning to identify the best uterine environments conducive to the establishment of the pregnancy. Embryo transfer is a normal approach to the introduction of livestock to the herd while maintaining Bio-Security and avoiding the costs of importing livestock from foreign countries where the transport costs would be very high.

  • cows and broiler chickens in County Cavan

    Travelled up North for a call to a dairy farmer outside Cavan who produces chickens for supply to the large multiple feed stores. He informed me that he gets 34 cent for chickens produced at 5 weeks of age. This type of return to the farmer is madness considering the margin made by the food stores at customer level. This farm gets gate price to cover the costs of heating, lighting. labour and depreciation of facilities . Dr.Dan @ www.cows365.com
  • Norweigan Red a cross-breed to improve feet and overall longevity of Holstein cows.

    Visited a dairy herd outside Portlaoise which presented a high incidence of general lameness in the herd. The client proposed using Norwegian Red as a cross-breed to introduce hybrid vigor into the Holstein cows as the longevity of the cows were severely compromised as the cows had to walk in excess of 1 mile to the furthest point from the milking parlour. However, the Norwegian Reds are noted as selective grazers and will not tolerate time grazing pressure as the New Zealand type cows. In my opinion, there is no need to use a cross-bred cow to address the main issue of lameness. Proper diet management and hoof care will all contribute to the maintenance of good feet and legs.

  • Pre-breed scan of cows fit for service in Upperchurch, County Tipperary

    Morning rise and time, first call of the day was up near Upperchurch, County Tipperary. Visited a client with a dairy herd where a low cost system had previously been put in place for grass based milk production in a Spring calving herd. Last year he, ended up with over 30% of his herd empty with a 20 week breeding period. Fortunately, he had 40 replacement heifers available to him which enabled him to maintain the same number of dairy cows this Spring. On his pre-breed scan today, over 90% of the cows were fit for breeding. He acknowledged that he had put in place a system of feeding which met the requirements of the cows for the level of milk of production and to award body weight loss in excess of half a kilogram per day, over the first 60 days calved. He has also introduced maize in the diet which is an excellent supplement to aid maintenance of BCS in freshly calved cows. Dr.Dan @ www.cows365.com
  • Pedigree Charolais Breeder is a Winner

    Visited a client in Westmeath who is a pedigree Charolais breeder. He was delighted that he recently presented at a show and sale in Carrick-on-Shannon and came away with not with one prize but with four prizes. He got top prizes for his stock at the show. It is great to see client’s achieving these awards for their efforts in breeding and showing cattle. Dr.Dan @ www.cows365.com
  • Jersey cow v’s Holstein Friesian cow.

    Visited a farm outside Ballyduff, County Waterford where a client posed a question to me should he go to cross breeding with the herd? He had been drawn down the route of cross-breeding but convinced that a first cross could be beneficial but that in essence, what problems are associated with this are making underlying stressors in the herd and they are not addressed, that problems will pertain no matter what kind of cross-breeding is put in place. I can take his point when I look at the high production herd of Pat & Sean Fullerton in County Derry with a rolling herd average of 9,500 litres where management is excellent and pregnancy rate to first service is consistently between 60 and 66% over the last 5 years. Therefore, careful selection of genetics within the Holstein breed will deliver on fertility on a high production system. Therefore, the work load placed in our cows should enable us to achieve pregnancy rates close to 50% and calving interval close to 365 days and this is without cross breeding. The final item that has to be remembered is that food supply worldwide is going to be in a crisis in the next few years because of the world surge in population growth. Therefore, these calves from the dairy industry are going to be an important integral element of food supply. Cross-bred Jersey cows will not meet this demand. Dr.Dan @ www.cows365.com
  • Uterine infections in suckler cows associated with calving difficulty.

    First call of the day entailed a visit to a suckler farmer outside Virginia, County Cavan, This client had a large number of cows presented which had uterine infections associated with calving difficulty. The cows had calved with the aid of a calving jack. I explained to the client that cows uterine repair had not taken place properly and uterine infections had established themselves in the womb. The demand for quality beef cattle has placed an emphasis on the use of sires which results in progeny which are large and result in calving difficulty. Dr.Dan @ www.cows365.com
  • Staphylocossus aureus in Lactating Dairy Cows

    On a farm visit in Co. Waterford where a herd of cows were presented which had been previously synchronised for AI in an autumn calving programme. The pregnancy rate was close to 30% and in my opinion, it was the wrong approach to take. The use of synchronisation in lactating dairy cows warrants that cows are fit for AI. This client took the easy option from a previous scan and decided to take all cows that were scanned and synchronise and AI them all in the one day. Oestrus synchronisation warrants that cows are fit for purpose and the only cows that should have been synchronised from this scan were cows with normal oestrus cycles and fit body condition. In the process of the visit, I found out that over one third of the herd had mastitis and this had been clinically diagnosed as an infection with staphylosossus aureus. My advice to the client is to ensure that the proper pre and post deep spray system was in place with proper hygiene in the cubicle house area. On inspection of the cubicles, I realised that there was no scrapers in place to keep the walking areas clean and that there was over 6 inches of slurry in this area. This would not be conducive to good hygiene and health of the mammary gland. Dr.Dan @ www.cows365.com
  • Cows on once a day milking as Super levy is imminent

    On farm visits in Co. Waterford today where all dairy farms visited have their milk quota for the year full and with Glanbia & Dairygold facing an imminent super levy situation, farmers are reducing feed intake to cows and putting cows on once a day milking to reduce level of milk production.

  • Dr.Dan's Weekly Farm Diary up to March 15, 2011

    Bees and cows as a business venture in Timoleague, West Cork I began the week with an early morning call to a Charolais herd in Ballyheigue, Co Kerry. I got down there at first light. It was akin to coming up from the bed blankets to see the rolling waves of the Atlantic Ocean from both sides of the peninsula as I travelled up from Ballybunion. This week was spent on call throughout the South of Ireland. A large number of calls entail small suckler herds with pedigree cows. Many of them have used embryo transfer to transfer genetics from their best cows. Farmers wait eagerly to know if the cows are in calf and secondly the sex of the calves. Many calves are delivered by caesarean section following embryo transfer. This arises because the sires used are generally scored high on calving difficulty and the recipients are maiden heifers. However, I consistently find that the reproductive future of cows is destroyed following caesarean sections, This should not be the case. On a far visit outside Roscrea, County Tipperary I met a beef farmer who produced both Charolais and Belgian Blue cattle using embryo transfer as tool. In the process of herd fertility management programme 15 cows were presented which had calves at foot following caesarean sections. In all of these cases there was no evidence of adhesions and 90% of the cows were cycling and fit for use as recipients again. These cows were Simmental Cross Friesian cows which produce a lot of milk for the calves at foot and are slow to put on weight post calving. These cows will make excellent recipients. I told the farmer to commend the veterinarian. The highlight of my week was a visit to a dairy farm outside Timoleague. This farm has a business focused on both milk and honey production. Milk produced on the farm is supplied to Barryroe Co-Op. Grass growth is early in this part of Ireland. Cows are out by day. However, they are kept in by night as the farmer does not want the cows to loose excessive BCS. These cows have a genetic potential for 8,000 litres of milk. Spring calving cows with this type of genetic potential for milk production will loose excessive BCS. The interesting part of this farm visit was the Bee Enterprise, which they had in place. They have 300 bee hives placed throughout West Cork. They harvest honey and sell it under the Molaga brand label. Saint Molaga was the first Saint to bring honey to Ireland. He settled in Timoleague and beekeeping has been in the area ever since. The production of honey as a business is also fraught with its own difficulties. The supply of honey to shops has to be on a year round basis. In order to meet the demand , honey has to be imported from Portugal. In the past they could catch 30 swarms annually but this has dropped to 10 swarms. The problem of viruses is one issue. This creates problems for fertility of the swarm. They are now considering the use of AI in bees to increase the number of swarms recovered. Great ingenuity has been used on this farm to harvest the honey and pack same in jars for your breakfast table. Regards Dr.Dan and all the team @ www.cows365.com
  • Belgian Blue calves can make excellent weanlings but leave a lot to be desired in terms of immunity.

    Having visited 10 farms today, all involved in the production of weanling cattle in County Clare. The major finding was that the use of Belgian Blue sires through AI on suckler cows as a terminal sire, produced excellent stock for the beef industry. However, the main concencus among clients visited was that the resistance of these calves to disease was poor. The calves were softer at birth and were different to rear relative to other cross-breeds. Dr.Dan @ www.cows365.com
  • Scanning cows with impaired reproductive performance.

    From Devlin, Co Westmeath, travelled up to scan a Limousin herd in Oldcastle, County Meath. This herd is faced with major fertility problems and cannot pin point where the problem lies. Investigations involving diseases and mineral status have not revealed anything significant to explain the severity of the problem. On to-day’s scan , many surprises were thrown at the client with cows presumed pregnant and confirmed not pregnant but reproductively sound. This situation is very difficult to explain Dr.Dan @ www.cows365.com
  • Use of sex semen in dairy cows.

    Sex semen resulted in pregnancy rate of 55% & 60% in 2 dairy herds in County Derry when used in conjunction with maiden heifers. Total number of heifers bred on one farm was 72 and 55 on the second farm. The number of heifers in total was a reproductive sample to evaluate the use of sex semen. It should be noted however that these results were achieved in conjunction with the removal of animals that are not suitable for the use of sex semen whereby a pre bred scan was used.

  • Holstein herd with a rolling herd average of 10,000 litres

    Final call of the evening was to a Holstein dairy herd with a rolling herd average in excess of 10,000 litres. The interesting feature of the pregnancy scan on this farm was the 20% incidence of twins among cows scanned for pregnancy today. Cows scanned for twins in the early stages of pregnancy need to be scanned at a later stage, ideally prior to 100 days( between 6o and 100 days) because the incidence of embryonic immortality is far greater than among single pregnancies where the incidence of embryonic death would be in the order of 5% from day 30 of pregnancy onwards. In cows carrying twins, the incidence of embryonic death associated with one or both foetus’s is in excess of 20%. Dr.Dan @ www.cows365.com
  • Scanning Romagnola Cows in West Cork

    On a farm visit to a client outside Innishannon, County Cork with pedigree Romagnola cows. These cows are very docile and excellent confirmation. Romagnola cows were previously introduced in this country about 30 years ago but fell out of favour because of the long gestation period and the time required to finish the cattle. This client was scanning cows to identify potential cows for purpose of flushing and suitability of cross-breed beef heifers as recipients. Dr.Dan @ www.cows365.com
  • Scanning Charolais cows in Ballyheigue, Co Kerry.

    Morning rise and time @ 5.30 a.m first call of the day brings me down to Ballyheigue, Co Kerry. Dawn this morning was about 6.15 a.m. When I drove into Tralee all was quiet as I came down along the coast with lovely views of the bay in Ballybunion stretching up into the peninsula and Ballyheigue. The coastline here is dotted with a ribbon formation of houses overlooking the coastline from all directions. Sea breezes in this region burn off any possibility of early grass from the winter period as the high salt content in the sea breezes burns off any grass growth over the winter period. Visited a Charolais herd breeder in Ballyheigue who complained that current hype regarding the price of Charolais cattle is very much media related. He brought 3 bulls to a recent sale. He got 2000.00E and he would have been better off slaughtering these bulls than to sell them at this price. The costs incurred in preparing and entering the bulls for this sale took away immensely from the price received. Of the cows scanned today, 10% were identified with twins and all were identified carrying mixed sex twins which left the client in very bad form as he considered the value of these pregnancies worthless.

  • Different type bulls at Perth sale compared to Ireland

    Visited a Charolais breeder outside Knocklong, County Limerick who had just returned from a show and sale in Perth for Charolais cattle. There was an average sale price of 6,000 guineas for Charolais bulls with approximately 80 bulls for sale. Top Charolais bull made 44,000 guineas, The client informed me that the same bull would not have won at the show and sale in Carrick-on-Shannon, Rationally different types of bulls compared to that bred here in Ireland.

  • The accuracy of the MooMonitor in heat detection

    Visited Dairymaster in County Kerry to see heat detection in cows using MooMonitor®. I travelled from County Limerick down to meet staff at Dairymaster to discuss research work conducted by ourselves for Dairymaster. Experimental work revealed that the heat detection rate using the MooMonitor®in terms of positive heats detected was in excess of 85%. This was uniquely validated by ourselves - Dr.Dan Ryan scanning as a tool to identify when cows come into heat based on follicler dynamics and CL development. Having seen the data presented in graphic form revealed how accurate the heat detection system was picking up the cows in heat for the purposes of AI. Dr.Dan Ryan @ www.cows365.com
  • The best cross-bred cow for production of weanling calvess

    On a farm visit today in Kilgarvan, Co. Kerry to a suckler farmer presented a range of suckler cross-breeds. Discussion with the client revealed that the best type of suckler cow was an Angus Cross Friesian crossed back with a Limousin and this cow crossed back with a Belgian Blue to produce as a terminal sire to produce weanlings for both the export and home markets.

  • Production of bull beef from Friesian calves

    Teagasc in conjunction with Larry Goodman have a programme of research promoting the production of bull beef from Irish calves rather than exporting the calves. The net profit over and above the sale of the calf would be €50-€60. However, many farmers would concur that rearing 300 calves on this type of programme, leaving a net profit of €15,000 would be one better off on the dole than taking risks associated with this type of a profit margin? In my opinion, I would agree that there is insufficient net profit to justify the type of risk associated with this type of investment. Dr.Dan Ryan @ www.cows365.com
