For spring calving herds, the end of the lactation is approaching so some important decisions need to be made to hopefully ensure a stress-free start to 2025.

Milk recording

Four milk recordings a year should be carried out to make better informed decisions all year round. A final milk recording should be organised close to the onset of drying off (ideally within 30 days), to help assist in decisions around selective dry cow therapy.

BCS

Best practise is to dry off cows at, or close to, the same condition she should calve down in (Target 3.0 – 3.25). Therefore, nutrition of the dry cow should centre around maintenance over 60 days. Thin cows should be prioritised for early drying off to assist in the recouperation of condition. Where large variation in a herd arises with BCS, batching accordingly and making a tailored plan is advisable.

Silage analysis

Nutrition depends on what silage quality (and quantity), is available in the yard, therefore silage analysis is crucial. High quality silage will need dilution with straw/hay to avoid over-conditioning. Additional energy sources through concentrates may also be required, where quality is poor.

Where ongoing issues occur with milk fever, retained afterbirth and/or slow calvings, a silage mineral analysis will establish Potassium (K) % in the silage being offered to dry cows. K levels > 1.8% can cause issues. Preventative plans can then be put in place.

Selecting a dry cow mineral

Feeding high quality dry cow mineral for 60 days is central to a cow calving down without issue next Spring. Most Irish silage lacks the mineral levels required by the cow and therefore requires balancing. Using a highly soluble source of Magnesium is essential to overcoming any milk fever risks; this should be coupled with the inclusion of complimentary Phosphorus, a high inclusion of chelated/protected trace elements to overcome antagonists, and a strong all-round vitamin pack (A, D3 & E).

With many cows dried off this month, the focus in most yards is on correct dry cow management. However, we must consider nutrition plans for cows calving down for the coming spring.

Several key factors directly correlate to the success of the calving season, including:

1. A planned and well executed dry cow mineral programme.
2. Calving down the cow in the correct body condition score.
3. Excellent animal husbandry in the week’s pre and post-calving (no additional stressors).
4. Careful transition diet planning.

Fast forward to late January/February, especially given how silage quality was hampered by the weather this year: do we have sufficient high-quality forage available for when cows calve down/and if not, what is the plan of action?

Negative Energy Balance

In the weeks post-calving, cows will always produce more milk than their feed intake can provide for, resulting in Body Condition loss due to Negative Energy Balance. For example, a cow will typically reach peak milk output 6-8 weeks post-calving but will only reach peak dry matter intake 10-12 weeks after calving. The freshly calved cow’s diet must be sufficient to keep body weight loss to less than 0.5 Body Condition Score (BCS) between calving and breeding.

Dry matter intake typically increases by 0.75 – 1.0 kg/week post-calving – highlighting the need for an energy-dense transition diet. This can be difficult to control where silage quality is compromised. Where a deficit occurs, we must be prepared to fill the gap, or issues such as poor fertility will come into effect in May. Adequate concentrate supplementation will be paramount (dependent on milk output), along with the inclusion of high-energy grazed grass in the diet.

Monitoring NEB on Farm

1. Falling/low milk protein % (signalling energy restriction in the diet – caused by poor quality silage, delayed turnout and/or insufficient supplementation levels relative to cow output).
2. Body condition loss across the herd (>25% of cows with a >0.5 unit of BCS loss in early lactation).
3. A bulk tank milk fat: protein ratio > 1.4 (calculated by dividing the milk fat % by milk protein %) signals poor energy balance in the herd’s diet.

Milk recording

As a rule of thumb, four milk recordings a year should be carried out to allow you to make well-informed decisions throughout the year. At this point, the final milk recording should be organised close to the onset of drying off, to help review dry cow plans regarding selective dry cow therapy (ideally within 30 days of drying off). In the current climate, milk recording will play a vital role in identifying our most profitable cows.

The final milk recording should be organised close to the onset of drying off, to help review dry cow plans regarding selective dry cow therapy.

Body Condition Score

It is always best practice to dry off cows at, or very close to same condition that she should calve down in (target 3.0-3.25). Therefore, the nutrition of the dry cow should just maintain condition over the 60-day dry period (thin cows should be dried off early to allow for recouperation of condition). Where large variation in the herd arises with BCS, a tailored plan is advisable.

Silage analysis

Nutrition for the dry cow will centre around what quality silage is available (silage analysis on forage available over the dry period is crucial!). High quality silage will need dilution with straw to avoid over-conditioning or where quality is very poor, some level of supplementation will be required.

Where issues have occurred on farm regarding milk fever, retained afterbirth, and/or slow calvings, a silage mineral analysis is advisable to establish K% in the dry cow silage being offered. Preventative plans can then be put in place to avoid such issues reoccurring.

Selecting a dry cow mineral

Feeding a high-quality dry cow mineral for 60 days is central to allowing the cow to calve down without issue. Most Irish silages lack the required mineral levels to get the cow through the dry period. A high inclusion of a highly soluble sources of Magnesium will be essential to overcome milk fever risks, which in any good mineral, will be coupled with a high inclusion of chelated/protected trace elements to overcome antagonist issues, and a strong all-round vitamin pack (A, D3 & E).

The Irish dairy cow is working harder now than ever before, with longer lactations and shorter dry periods. In contrast to much of the global dairy herd, the predominant typical Irish dairy cow consumes her dietary requirements primarily from grazed and conserved grass, meaning that less concentrate is fed during the lactation.

As grazed grass is generally low in minerals and trace elements, and with concentrate mixtures generally supplemented with some level of minerals, spring calving grass based dairy cows can become quite depleted of minerals by the end of their lactation. It is therefore vital that the dry cow is supplemented with a high quality mineral throughout the entire dry period. 

Following a dry cow management plan has proven very successful for Co. Westmeath farmer, Hugh Gaffney. Alongside his father, Mattie, Hugh is milking a herd of 120 British Friesian cows just outside Killucan, Co. Westmeath. The farm is run on a grass based, spring calving system, with bull and heifer calves later sold as stores.  

According to Hugh, giving close consideration to good nutrition, careful management, and the addition of a high quality dry cow mineral has played a vital role in improving health and immunity in both his cows and new born calves.

Dry Cow Management Plan

How you feed and manage your herd during the dry cow period will influence subsequent yields and fertility, along with conditions which manifest post calving, such as milk fever, metritis, ketosis, and displaced abomasums. 

A key part of Hugh’s dry cow management plan is monitoring body condition score (BCS), and correcting where necessary before calving. Hugh’s dry cows are batched according to BCS and cubicles are maintained in a clean hygienic manner throughout the dry period. It is best practice to dry off cows at, or close to, the best BCS for calving (3.00 – 3.25). It is also critical to maintain this condition score throughout the dry period. 

Agritech recommend a silage quality target of at least 72DMD. In addition to receiving good quality forage and supplemental concentrate where necessary, Hugh’s cows are fed a minimum of 6kgs of Agritech’s Welmin™ Dry Cow Elite mineral before calving. This is viewed as critical in order to improve health and immunity and reduce the risk of metabolic disorders in his herd.  

Dry Cow Elite

Key macro minerals required by the dry cow include high availability magnesium and trace elements such as organic selenium, chelated and hydroxy copper and zinc. Welmin™ Dry Cow Elite goes further than other dry cow supplements in terms of bolstering the cow’s immune system ahead of the rigours of calving through the inclusion of supplemental B vitamins, ImmunoWall yeast, and high levels of key vitamins A, D3 and E. This complete package is crucial in order to increase health and immunity, minimise retained placenta levels, and aid the uterine involution (cleansing) process post calving.

Addressing the bioavailability challenge

Agritech’s Welmin™ Mineral Range has also been at the forefront in addressing the bioavailability challenge; a challenge which has led to secondary mineral deficiencies becoming more prominent in modern livestock operations. These deficiencies are a result of antagonists binding with key minerals in the rumen, ultimately causing them to pass through the animal unabsorbed.

It is now widely accepted that the inclusion of elements from multiple sources significantly enhances the absorption of each element. Agritech have embraced this superior approach as their mineral range includes copper, selenium, iodine and zinc from multiple sources to ensure optimum bioavailability of these key elements. 

Intellibond C is also included in many of Agritech’s mineral mixtures, which is a highly available source of copper. Intellibond C is not soluble at neutral rumen pH which results in a rumen by-pass trace element that gives increased trace mineral stability in the intestine. Copper from Intellibond C is released slowly over the full length of the small intestine, resulting in more efficient copper absorption and thereby improving overall intestinal health.

With most Irish dairy herds calving in the months of February and March, now is a very important time to apply some key practices that will influence the 2020 lactation.

The key influencers of a productive and profitable 2020 lactation are:

• Body condition score
• Udder health
• Stress free drying off

BODY CONDITION SCORE

Body condition score (BCS) is the foundation for a successful start to the cow’s lactation. The ideal BCS score range is 3.0 to 3.25 in most herds. Cows calving down in this range experience less metabolic issues in early lactation e.g. milk fever, metritis, displaced abomasums.

A simple system to manage BCS for the dry period is to divide cows into three groups:

Group 1: Cows in the 3.0 to 3.25 range. This group should be stocked at one cow per cubicle and fed silage to maintain body condition, e.g. 12 kg of silage to provide 6 UFL/ day.
Group 2: Cows in this group are under 3.0 BCS. This group should be stocked at 90% of a shed’s capacity. This reduces competition for feed space and promotes a more relaxed environment that will encourage live-weight gain in the cow. This group should receive high quality silage or meal to provide 8+ UFL/day.
Group 3: Cows in this group are over 3.25 BCS. This group need to either maintain BCS or lose some body weight. This group should be stocked at a slightly higher shed stocking rate e.g. 110% of a shed’s capacity, which will create a little more competition within the group for feed and space. This group should be on a restricted silage diet to provide less than 5.5 UFL/day. However, additional roughage should be provided to ensure the cow achieves optimum rumen fill.

Note:
• It is important that all groups are monitored regularly to ensure they reach the optimum BCS of 3.0 to 3.25. Cows should be moved from their groups if they are moving outside this range.
• It is critical that a dry cow mineral is provided to each of the above groups. A dry cow should receive a minimum of 6 kg of dry cow minerals in advance of calving in order to ensure that she is adequately replenished and prepared for calving and next year’s lactation.

• It is essential to provide fresh clean water adlib.
• All cows should be moved from their groups 14 days pre-calving to a transition group where they are introduced to an increased energy and protein diet.

UDDER HEALTH

With an increasing pressure to reduce antibiotic use in the dry period, shed hygiene is becoming ever more important during the dry period. Factors which promote a hygienic environment include:

1) Adequate lying space (1 cubicle per cow).
2) Adequate feed space.
3) Adequate ventilation.
4) Adlib fresh clean water.

In addition to this, most Irish dairy farms use a bedding conditioner on cubicles. A good bedding conditioner should meet the following criteria:

• Highly absorbent to control bacteria growth.
• Be kind on both the farmer and animal’s skin.
• Absorbs ammonia odours to help air quality and reduce stress on the animal’s lungs.
• Easy to apply in a low volume per square meter.
• Contains effective antibacterial properties.

A good example is Sanitise Bedding Conditioner, which is designed to promote a dry hygienic environment in the bedding of all livestock. This product goes above and beyond traditional methods due to its low application rate as well as the inclusion of high quality essential oils, antibacterial properties, and a unique hoof conditioner.

Planning ahead is the key ingredient for success. Below we outline a number of key tasks that farmers must address to ensure that they are ready for the New Year.

Silage Analysis

Favourable weather conditions created excellent autumn grazing conditions across the country, enabling many farms to bulk up silage stocks and reduce the risk of fodder deficits this winter. Despite this, it is essential not to become complacent, therefore we recommend that every farm establishes the quality and supply of silage in order to ensure that all animals are fed for optimum performance. Simply measure length x width x height (metres)/1.4 to give an accurate assessment of fresh tonnes of silage in the pit.

Cow Body Condition Analysis

Cow body condition analysis is one of the most important jobs to be completed on farms at this time of the year. We recommend that farmers segregate under conditioned cows, especially first time calvers and those carrying twins, and supplement appropriately. A simple mix of soya and a barley or oats blend will fit most situations with the ratios and feeding levels dictated by silage quality and cow condition.

Dry Cow Mineral Supplementation

Dry cow supplementation is essential for this time of the year. With a feeding recommendation of 100 grams per head per day, it is important that an increased amount of feed per day is given to cows who started their dry cow supplements late. A dry cow should receive a minimum of 6kgs of dry cow minerals in advance of calving in order to ensure that she is adequately replenished and prepared for calving and next year’s lactation.

Housing Hygiene 

With herd sizes increasing, the pressure on calving facilities and calf housing has become intense on many farms. If you suspect that cryptosporidium is a problem on your farm, it is important to ensure that the disinfectant you use addresses this hazardous threat. Steam cleaning is also a very useful tool in the fight against this parasite. It is highly recommended to apply a suitable hygiene product such as our Sanitise Bedding Conditioner to the disinfected area.

Vaccinations

A ‘dry’ farm is not an assurance against fluke infection, therefore the herd should be dung sampled to establish if parasites exist. Many of the anti-scour vaccines have a recommended application time of between 12 and 3 weeks before calving, making now an excellent time to vaccinate the early calving portion of the herd. Be careful to adhere to the regulatory guidelines when addressing fluke infections.

Soil Testing

Now is also a great time to carry out the required soil tests on your farm. Ideally, the optimum time to test is 12 + weeks following the application of chemical fertilizer or slurry. When soil testing, it is important to ensure that the test taken is an accurate representation of the area being tested. This is best achieved by using a soil core and walking the area in a ‘W’ formation. 250 grams is an adequate amount of soil to include for each sample.
