Parameter Target Calving-conception interval interval 60% Number of inseminations per conception. Limousin GEBVs Common Questions and Answers Age at First Calving and Calving Interval are recognised as key financial drivers in most types of breeding herd. The effects of high and low performance are well documented. • Improving female fertility in suckler cows has been shown to increase herd returns by up to £54/cow served per annum.
Cattle Genie Limited from the bull stud of KI-SAMEN. The proofs displayed are from the DECEMBER run. The Blaarkop breed is the most fertile of all popular dairy breeds recorded in the Netherlands & the shortest gestation length also. The breed is often utilised in cross breeding with Friesian dairy herds . The most prof- achieves the highest nancial gross margin per cow, itable herds owe their success to producing a large but spring calving rivals its gross margin per hectare. number of live calves per cows bulled, with low calf The need to reduce production costs has forced many mortality, rapid growth to weaning and a high sale value former.
Drying off the dairy cow The dry period is the most important phase of a dairy cow’s lactation cycle. During this phase, the cow and her udder are prepared for the next lactation; hence any abnormalities during the dry period will have a negative effect on the cow’s health and milk production after calving. Endoparasites are one of the major health issues in beef suckler cows and can cause economic losses. As studies on the parasitological status of beef suckler cow herds are rare, the aim of this study was to evaluate the status quo of the parasite burden in herds at four representative locations in Germany. Additionally, the farmers’ pasture management and deworming strategies were documented.

• Longer calving interval reflects a less structured calving pattern • Recycling cows between seasons, protracted spring calving patterns • Traditionally less emphasis on fertility traits in breeding programme • Manufacturing herds with poor fertility often mislabelled as ‘winter milk’.
Compact calving periods in suckler herds could help boost producers’ net margins by up to £ per cow, according to EBLEX. It is among a range of management factors that can increase system profitability, helping top producers generate £ to £ per cow more net margin, excluding non-cash costs, than average producers.
Many native breeds such as the Beef Shorthorn are naturally fertile, with some herds achieving % of cows calving within two months, maintaining a compact calving period (Beef Shorthorn, ). Table 1: A gross margin for an average performing, upland spring calving suckler cow per.
Introduction. Calfhood diseases have a major impact on the economic viability of cattle operations, due to the direct costs of calf losses and treatment and the long term effects on performance .Calf health was prioritised as one of the most important animal health issues facing the Irish livestock industry in a recent expert Policy Delphi study conducted on behalf of Animal Health Ireland Cited by: Trade-offs between indicators of performance and sustainability in breeding suckler beef herds Article (PDF Available) in The Journal of Agricultural Science July with 89 Reads.
Fertility results for Scottish suckler herds QMS figures for the average Scottish suckler herd show that only 87 calves are weaned for every cows and heifers put to the bull.
While calving heifers at 24months can prove problematic, so too can achieving a day calving interval from there on in. According to Professor Kenny, this is more challenging in suckler cows than dairy animals due to her suckling calf which prevents the early onset of heat cycles after calving.
They can help ensure age at first calving is 24 months, which has been proven to be the optimal to maximise milk yield in first lactation. In the case of suckler herds, reducing calving to conception through synchronisation strategies could mean in some cases an extra calf. The same is true for suckler herds focus on the uro Star Index and areas where further improvement in cow / herd performance is possible.
It’s stating the obvious but every year a cow doesn’t produce a calf she’s reducing the proffitability and increasing the carbon footprint of the rest of the herd. Effect of cow replacement strategy on cow and calf performance in the beef herd Such a development is contrary to the present goal of the suckler cow herds which is primarily that of reducing.
The Red Poll cow is the ideal suckler dam, having been selected over the centuries for the maternal traits of high milk yield from rough forage, early maturity (first calf at two years old) and short calving interval.
She is capable of calving the progeny from the more muscled terminal sires without assistance. Fertility. Recent Irish trail data conducted by Teagasc & UCD showed a positive improvement in reducing the days open in dairy cows and showed strong management benefits associated with beef suckler cows.
Remember, good management and nutrition is vital in the success of any adopted program. Theriogenology The mean calving interval wasand d in the suckling, milked beef and dairy herds, respectively.
These means were significantly different (Pinterval with the number of lactations. calf in the first place. Farmers should aim to produce one calf per cow per day interval. In most suckler herds a shorter calving and breeding season brings further advantages in terms of reduced labour, production costs, simpler animal management, more calves and fewer and fewer calf.
However, as suckling and poor nutrition are amongst the most important factors influencing calving interval in beef cattle earlier weaning, usually at about days of lactation, is also being recommended to increase reproductive rates in extensive pasture systems .
Other strategies to improve calving intervals involve preventing.

Rabbits are strictly herbivorous with a preferred diet of herbage that is low in fiber and high in protein and soluble carbohydrate (Cheeke,).Rabbits will generally accept a pelleted feed more readily than one in meal form. When a meal diet is needed, a period of adjustment should be allowed for the rabbits to accommodate to the new diet.
With our Spring calving herds into their calving period its now a good time to be considering how long the calving window was, the benefits of tightening it (if applicable to your business model) and the methods we can employ to achieve this.
The average cost of production for British suckler herds is ££ per cow per year therefore it. Written in a practical and user-friendly style, this book aims to help the reader understand cattle reproduction by explaining the underlying physiology of the reproductive process and the role and importance of pharmacology and technology, and showing how management techniques can improve reproductive efficiency.
Further positive associations were found with dams becoming positive after the birth of the subject; a dam seroconverting within 12 months post parturition being associated with a fold increase in hazard (95% confidence interval: –, p = ), and dams seroconverting more than a year after calving increased the hazard by a factor.
There were two herds of male calves (mean live weight ± 43 kg) and two herds of female calves (mean live weight ± 49 kg). Calves single-suckled their dams over the 7-mo grazing season on a perennial ryegrass sward.
One week before weaning, all calves were weighed. Jordan puts the herds exceptional calving ease down to the annual pelvic area measuring of potential replacement heifers to ensure that they are fit to calve themselves. Jordan first saw the tool in practice on a trip to the US and was determined to bring it back to Mains Rigg.younger calves.
This method is called the Sandhills Calving System (SCS). It is effective with divided pastures or with confinement pens.
