As we approach calving 2021 the focus should be on final preparations that will result in a spring free from any upsets, nutritional issues or metabolic diseases during an already busy time on farm.

Several key factors will correlate directly to the success of calving 2021, including:

• A planned and well executed dry cow mineral programme
• Calving down the cow in the correct body condition score
• Excellent husbandry in the weeks pre- and post-calving
• Careful transition diet planning

It is always worth remembering at this time in the year, that key decisions made over the next number of weeks will have a direct e­ffect on the performance of the herd, especially herd fertility – submission and conception rates, ultimately a­ffecting the longevity of the cow within the herd.

Negative Energy Balance

In the weeks post-calving, cows will produce more milk than their feed intake can provide for, resulting in Body Condition Score (BCS) loss due to Negative Energy Balance. Research has shown NEB will firstly, reduce milk protein and if prolonged, have detrimental consequences on the breeding season.

The milking cow should receive an adequate diet to optimise milk solids production and keep body weight loss to less than 0.5 BCS between calving and breeding. Cows that lose < 0.5 BCS over this time (approx. 25 kg) typically ovulate 15 days earlier than those cows that lose 1 BCS during this period.

Dry matter intake typically increases by 0.75 – 1.0 kg/week for the first 8 weeks of lactation, therefore being 8 weeks post-calving before maximum intake is reached – highlighting the need for an energy-dense transition diet.

Every farm scenario is different, and tailored advice should be given where issues arise. However, early preparation and planning is vital to avoid added stresses on farm

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.

The freshly calved cow is genetically programmed to produce high levels of milk, however, to ensure maximum performance, it is essential to implement a feeding and management strategy.

The first number of weeks before, and after calving, are the most critical periods in the production cycle of the modern dairy cow. The consequences of failing to feed freshly calved cows adequately during this period can be significant and can lead to costs such as lower production, slower returns to heat cyclicity, and subsequent poorer fertility. Lower peak yields will also mean a lower milk performance for the rest of the lactation.

To keep your freshly calved cows healthy and productive during their lactation, follow our step-by-step management guide below:

Key Areas to Monitor:

1. Body Condition Scores (BCS): Are your cows holding their pre-calving BCS? If your cows are losing condition in the weeks post calving, it must be addressed promptly by seeking professional advice.
2. Milk Yield: Are your cows milking to their potential? Lower yields will mean a lower milk performance for the rest of the lactation.
3. Milk Fat to Protein Ratio: The ratio of fat:protein is an excellent indicator of cow health and feed efficiency. The ideal butterfat:protein ratio is circa 1.27:1. Where the ratio goes above 1.5:1, strict attention should be paid to cow health as there is a strong possibility of ketosis in the affected animals. Where the ratio drops below 1.2:1, a possible link to rumen acidosis exists.
4. Dung Consistency: Dung that appears firm indicates that the cow’s diet may be too low in protein and too high in fibre. A loose and thin consistency suggests excess protein/carbohydrates or low fibre, which may possibly lead to acidosis.

Key Tips:

1. Maximise dry matter intake (DMI) through a well-balanced diet formulation and continuous assessment of rations fed to cows.
2. Supplement with adequate concentrates to allow your cows to perform in line with the forage they are currently consuming and not the amount they received in recent years when grass was a contributor to their diet.
3. Ensure that there is a minimum of 600-800 mm feed space per cow, along with clean drinking water and ample drinking points.
4. Introduce concentrates slowly over a five to ten-day period post-calving. Adding concentrates too quickly, in an attempt to provide energy is a recipe for Sub Acute Rumen Acidosis. Introducing a high quality rumen buffer such as Rumicare from Agritech will help counteract rumen and intestinal acidity and has the added benefit of providing much needed calcium, magnesium and sodium for the early lactating dairy cow.
5. Continue to analyse your cow’s BCS on a regular basis. It is vitally important to maintain adequate BCS to ensure that the cow quickly returns to cyclicity in advance of the breeding season.
6. Supplementation of post-calving minerals is a much-neglected area, as many dairy farmers assume there are enough minerals in the purchased concentrate. However, unless there are very high levels being fed, this is rarely the case. The post-calving diet needs to be carefully monitored to ensure that the cow receives adequate levels of macro and trace minerals at this important time. Take a look at our Welmin Mineral Range brochure here, which features a number of products suitable to help you get the most from your freshly calved cow.
7. Introduce grazed grass into the diet as soon as possible.

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.
