How to crack the transition from autumn grazing to winter housing

How to crack the transition from autumn grazing to winter housing

For most farmers the growing season has been a rollercoaster ride this year. The old wives tale, ‘ash before oak and we’re in for a soak’ could have not rung truer as we endured a prolonged cold and wet spring. We didn’t really see summer until June, but that didn’t last long as most donned their waterproofs all through August.


Writing this in October, we are still seeing some calves, heifers, and cows out and farmers taking their last opportunity to grab anything from second to fourth cuts ahead of the fast approaching winter months.

Trouw Nutrition has aggregated results from the first 500 crop samples of 2023 and reported an average 30.9% dry matter, 11.1 MJ/kgDM energy (lower than 2022) and 44.5% NDF (same as 2022).

AHDB have reported also indicate that deadweight cattle prices have been on the up to £4.81 per kilogram across England Scotland and Wales, recovering from the dip in July.

With this all in mind, it is really important that housed-beef systems proactively plan for the winter to ensure we see the benefits at the other end.

Lauren Evans gives us some non-negotiables for maximising beef cattle health and performance.

1. Vaccination Programme

Beef youngstock can be affected by a multitude of diseases namely pneumonia, IBR, BVD, Leptospirosis, and RSV.

Sampling can be undertaken by your vet to determine the pathogens on your farm alongside other variable factors before determining a suitable pneumonia vaccination strategy. Blood samples or nasal swabs can be taken and can often be funded under animal health pathways through Farming Connect (Wales) and Animal Health and Welfare Review (England).

An unavoidable level of stress at housing from diet changes, weaning and the change of environment will impact on the animals ability to build up immunity. When vaccinating for respiratory disease prior to housing, ensure it is administered at the optimum time – usually 3 weeks before heading indoors – to ensure the animal builds up adequate immunity first.

Top Tip: Clipping the hair from the back of the cattle at housing can help to prevent overheating and reduce sweating, which then reduces the humidity of the shed which in turn can aid reduction in pneumonia outbreaks.

2. Parasite Control Programme

Parasite control at housing is good practice to ensure cattle are free from any production-limiting parasite burdens.

Beat the Parasites ‘10 tips for parasite control at housing’ blog

Winter parasite control depends on each individual system, specifically timings of housing and age of cattle, but should always follow Faecal Egg Count (FEC) testing and fluke sampling to ensure treatment is given responsibly where needed, thus reducing the risk of resistance. Advice should be sought from suitable professionals SQP’s and vets who will study the farm’s history and current status to plan accordingly.

It’s important to stress that herd health plans and the control of common cattle diseases is farm-specific, and farms must work closely with their vet to form sustainable and responsible strategies.

Top Tip: APHA are running a project ‘What Worms? Project’ where samples can be submitted through your vet (England & Wales) from 10 calves which have been grazed for their first season. An opportunity to receive a free FEC and to help towards a study looking at benzimidazole (BZ) resistance.

3. Housing Optimisation

Feeding Space

Sufficient feeding space is one of the most basic requirements for enabling feed intakes.

It’s important to keep the feed space and feed offered clean and well in reach for the cattle, a smooth floor material will make this easier for consumption. An easily accessible feed space will reduce the labour needed to push feed and remove waste feed. With whichever feed option used – be that barriers, troughs, rails – it is important to maintain these prior to the housing period to ensure there are no protruding sharp edges which could cause injury. Inspection of the facility should be continued whilst cattle are housed.

Feed rails should be around 500mm high for adult cattle with a smooth edge and neck rails should be ideally adjustable from 1150-1250mm for adults and 900-1100mm height for younger cattle from floor level.

Group size, cattle size and feed type will influence the feed space and barrier width required by cattle. The AHDB Better Cattle Housing Design resource goes into further depth in housing but as a gauge for cattle weighing between 300-600kg the requirements for feed barrier width are between 500-650mm per head.

Animal Weight (Kg) Width of feed barrier (mm/animal) Ad-Lib Feeding (mm)
200 400 150
300 500 150
400 550 190
500 600 240
600 650 280
700 700 320
800 750 320

Water Supply

Intake of fresh clean water is positively correlated with feed intake and essential for productivity. Growing and finishing cattle can consume between 15 and 75 litres of water each day so a good supply is needed to meet demand at peak times.

Water troughs should be kept clean and free from feed, bedding, and manure. Regular inspection and cleaning can help with this and locating troughs away from direct feed sources will minimise the risk of feed contamination. Tipping troughs can speed up the cleaning process however it is important that there is sufficient drainage in the vicinity to reduce the build-up of moisture within the cattle housing.

Bedding Area

Livestock will produce moisture through their breath, urine, faeces and sweat. Poor drainage and damp bedding can also contribute to humidity build up. Selecting the right bedding and implementing a proactive cleaning rota will help reduce the moisture build up which could negatively impact the health and performance of the housed cattle.

It can be useful to insert a step/ridge of a maximum 300mm between the feeding and bedding area when loose housed to segregate straw bedding. This can help to avoid slurry contamination as feeding and loafing areas will be cleaned more regularly than the bedded area. Passages for cattle less than one year of age will require a passage width of at least 2 meters to allow for enough space to feed and move around.

Appropriate machinery such as a straw chopper can speed up bedding time, whilst reducing stress on the livestock and labour required for the task.


Fresh air is a primary requirement for optimising health and productivity. Sufficient ventilation will facilitate the removal of heat, moisture, dust, gases, and micro-organisms from the building. Fresh air plays a vital role in eliminating pathogens, bacteria, and viruses.

According to the AHDB Better Cattle Housing Design resource; 100% clean, fresh air can kill airborne bacteria and viruses 10–20 times quicker than 50% clean, fresh air. It is important that buildings are suitably ventilated to remove contaminated air and replenish with fresh air without creating a draught and exposing stock to excessive wind speed.

4. Feeding Strategy

Transition from grazing to housing

The transition from grazing-based diets to silage-based diets should not happen overnight but should gradually transition to give the rumen time to adjust. Without this, cattle are at a greater a risk of having acidosis, stomach ulcers and liver abscesses.

Weaning calves should be creep-fed for 3-6 weeks before housing to help develop their rumen and avoid any dips in intakes at a time when they need it most.

Most grassland, forage, silage and hay in the UK and Ireland is deficient in one or more trace elements. Cattle that have enough trace elements coming indoors will have a better supported immune function and response from any vaccines as well as a greater ability to digest and convert what they eat into liveweight gains heading indoors.

Making the most of winter forage

We need to start out by looking at our forage analysis results before making any feeding and management decisions. The feed value analysis will detail energy and protein values along with fermentation values. This will determine the amount of forage the cattle will need to perform at the rates set out. The mineral analysis will define the macro minerals and trace elements within the forage.

Forage Sampling Best Practice

Sampling can be performed by an array of professionals – nutritionists, merchants, contractors etc. Samples should be taken using a corer in a ‘W’ shape at several locations across the clamp, not just at the clamp face.

Analysing multiple samples over the winter will detect changes in the silage as you move through the clamp or when moving to another clamp. The frequency of sampling will depend on whether the clamp was filled in blocks, layers, multi cuts etc.

If feeding big bales, samples should be taken from each cut or fields as identifiable.

Winter forages may well supply enough energy and protein needs for your livestock; however, most are deficient in one or more trace elements. An absence of any of the essential trace elements in winter forages – cobalt, copper, iodine, and selenium – will impact on metabolic processes. This will have a knock on effect on digestion, immunity, reproduction, and growth.

This can manifest into costly treatments and costly underperformance. We’ve worked hard and invested a lot of time and energy into making the forage, so it’s vital we don’t fall at the last hurdle and balance the forage as needed to get as much out of it as we can.

5. Trace element supplementation strategy

Almost all soil, and therefore grass and forage, is deficient in one or more of the trace elements essential to an animals digestive, immune, and reproductive system.

Undersupply of trace elements can manifest as costly clinical or subclinical health and production challenges. Conversely, supplying more than enough will either by-pass what an animal can physically absorb or cause toxicity. Oversupply of trace elements is a waste of money and can be a risk to the environment.

When adding feed and feed supplements, we still can’t be sure every cow and unborn calf is getting ENOUGH all the time for optimal performance.

By proactively bolusing with ANIMAX Tracesure®, featuring patented diffusion technology that offers a controlled and consistent supply of the right trace elements in the right amounts, you can be sure that every animal is getting enough during the transition – no more or less, and no peaks or troughs.


Important in growing ruminants, Cobalt is converted by rumen bacteria into Vitamin B12 critical for energy cycles, metabolism, cattle growth, and pregnancy.

Cobalt is only stored in the animal in small quantities. A continuous supply is needed. Tracesure offers a form of cobalt that is available in the rumen where the bacteria can utilise it.


Selenium is critical for normal cell function and essential for effective immune responses to viral, bacterial and parasite encounters. Selenium also supports the recovery from routine cell damage, commonly referred to as oxidative stress.

ANIMAX Tracesure® with its specialist diffusion technology, contains the highest levels of selenium of any bolus in a safe form.


Iodine is an essential component of the thyroid hormone responsible for regulating metabolism.

ANIMAX Tracesure® contains two types of iodine to ensure an immediate supply as well as a longer term supply.


Copper is required by cattle for enzyme function and can promote positive weight gain.

The ANIMAX Tracesure® cattle range offers copper in the form of copper needles that lodge in the rumen wall before gradually dislodging and passing through into the abomasum where they are absorbed in the small intestine and stored in the liver. This facilitates a more consistent and continuous long-lasting supply of copper compared to other sources.
