Increase the welfare and profitability of your herd

Summer heat stress is considered one of the major causes of losses in the global dairy industry. In addition to significant losses in milk production, heat stress can reduce the conception rate of dairy cows by up to 30%, and its effects can last into winter, with progressive deterioration over the years. The consequences are known to all dairy farmers: if the barn is not adequately cooled, from summer to autumn there is a drop in intake, a drop in production, a drop in milk quality, a drop in reproductive performance and a drop in health status.

The Summer/Winter index compares the average summer and winter milk production of a farm. The closer the index is to 1, the more optimal the herd’s production, and vice versa.
The S/W index was first used in Israel, with the fundamental contribution of Prof. Israel Flamenbaum, and has been used for many years as a management parameter integrated into the farm routine.
The Italian Breeders’ Association (A.I.A.) has recently adopted the Summer to Winter index (S/W INDEX), as a fundamental tool to evaluate the thermal stress of the farm.
By calculating the Summer/Winter Index over the years, integrating appropriate technological monitoring solutions with cooling/cooling systems, it is possible to constantly and easily evaluate the results achieved by your farm, improve production and even anticipate possible criticalities in your farm resulting from heat stress.
In Israel, in 2017, the S/W Index on farms was:
0.98% in 23% of the stables
0.95% in 66% of farms
0.91% in 11% of the stables

In Italy the average S/W Index is about 0.85: this means that summer production is just 85% of winter production, which is equivalent to losses of tens of millions of euros.

It is not about fans, it is important to clarify this aspect, often a farmer already has a cooling system. Arienti’s Elements Program is a package of products and services, an INTEGRATED SOLUTION to your farm management, through which the summer performance of your farm can be superimposed on the winter performance. The Elements Program is a mix of cooling systems, automated barn procedures, monitoring of values and constant verification of results, which has proven to have a strong impact on the economic sustainability of the dairy farm at 360 degrees: increased milk production, better fertility, improved health of the cows and consequently a clear increase in farm profits. These are words, no, the data prove it.

Farms following the “ELEMENTS PROGRAM” achieve outstanding results with an S/W Index of 0.98, which translates into production losses of less than one litre of milk in the summer months and practically unchanged fertility throughout the year. For the farm, these results translate into tens, but more often hundreds of thousands of euros in additional annual revenue.

1. S/W Index and ECONOMIC PLAN. One of the first actions of Arienti’s technicians is to calculate the S/W Index of your farm: this data will highlight the potential margins of production and economic efficiency of the farm. (We remind you that until 31st March 2022 you can request the calculation of the S/W Index and the business plan free of charge).

2. ANALYSIS OF THE BARN. Once the S/W index and the eventual economic loss linked to it have been calculated, the Elements Program provides for the actual analysis of the structures and cooling systems present in the farm and the analysis of the stable procedures.

3. PCORRECTIVE DESIGN The analysis leads to a third phase: the design of corrective measures (both structural/plant engineering (environmental settings, cooling systems, irrigation systems, lighting and windbreaks) and stable operating procedures (presence of animals, movements, times, methods of supplying fundamental elements: air, water, light).

4. OPERATIONAL PHASE: INSTALLATIONS AND PROCEDURES. After the presentation of an estimate and possible acceptance, we move on to the production of what was defined in the project phase: we therefore go on to the installation (or adaptation) of the cooling systems and the setting up of the stable operating procedures. The prerogative is to obtain an automated cooling management, with less work for the breeder, against a greater welfare of the farm and production efficiency.

5.TEMPERATURE MONITORING The temperature monitoring phase involves the insertion of vaginal data loggers on a representative sample of the herd (eight cows per group), in order to monitor the basal temperature of the cows. (In fact, there is strong scientific evidence that the productive and reproductive performance of cows is fully preserved when their core temperature is below 39.2°C. Action must therefore be taken to ensure that the animal maintains this value for as long as possible, ideally throughout the day). Temperature monitoring will enable the new stable settings to be verified and any necessary improvements to be made.

6. VERIFICATION OF RESULTS AND CONSTANT SUPPORT. At pre-defined intervals, Arienti technicians, together with the breeder, check the systems, monitor the conditions of the farm and follow the results, also in economic terms, providing short-, medium- and long-term data, for constant support, health and production security.

In this study, the S:W ratio was calculated for the year 2020, on 2,400 Friesian cow farms, located in the Po Valley of the Lombardy region. The calculation was based on official data from functional controls, collected by AIA technicians. The information considered included milk yield corrected for fat and protein content at 4.0% and 3.3% respectively (FPCM), milk fat and protein percentage (%), somatic cell count linear score (SCC) and conception rate (CR%), for all inseminations carried out in the summer and winter of 2020.
The study also focused on a group of 99 farms participating in the Element intensive cooling programme of Arienti, a manufacturer and installer of farm cooling systems.
The monthly averages for the three years considered of the milk production and conception rate of the 36 farms that started the Arienti Element programme in 2019 are shown in Figure 1. The graphs describe how the performance of the cooled cows evolves over the three years considered.

Figura 1 – Monthly averages of (a) corrected milk (kg/cow/day) and (b) conception rate (%) on all registered inseminations.

From the data represented in figure (a), we can see a clear trend of continuous growth of the average production per cow. The average winter production per cow increases from 35 kg in the year before the start of intensive cooling to 38 kg and more in the summer of 2020, where cooling has been adequately provided for two consecutive summers. It can also be seen from the graph that the difference in production between summer and winter goes from 4-5 kg per day to 1-2 kg in the following years. As can be seen in figure (b) the conception rate gap in 2018 was 10 percentage points (going from 45% winter to 35% summer), while after two consecutive years of cooling the decrease is around 5% (going from 50% winter to 45% summer), i.e. half of the decrease compared to the year before the start of cooling, but above all achieving summer reproductive performance almost comparable to the winter performance in the pre-cooling period.

As can be seen from Table 2 and the two previous graphs, the improvements in production levels after the first summer of intensive cooling are less than those achieved in the second summer (about half of the improvement in the S:W index), while as far as reproduction is concerned, the improvement is already completely achieved in the first year.

The continuous improvement in summer milk production in the two years analysed can be attributed to the fact that the intensive cooling of the cows in summer helps them to eat more and, although they produce more, they are still able to accumulate more body reserves in the last phase of lactation and lose less in the first phase of the next lactation, especially when this transition phase takes place in summer. In this way, cows maintain a better body condition that positively influences both milk production and fertility in general, especially in the summer months. The improvement of CR already in the first year of intensive cooling has as an immediate consequence the decrease of the average calving distance (average DIM), with the consequent increase of the average farm production and the improvement of udder health.

Graphs of farms that have chosen the Elements Program

Az. Agr. Principi di Porcia e Brugnera Azzano Decimo (PN)


The dairy cattle farm consists of approximately 110 heads with an average annual production of 31 kg/head/day. At the beginning of summer 2018 the cooling system was installed in the waiting room and in the feeding lane in one of the two groups.
Preliminary production data are striking, the group of cows subjected to the full cooling protocol (red line) showed a clear increase in production: +5k g/head/day, while the group of cows that was cooled only in the waiting room showed a drop in production related to heat stress.

Az. Agr. Bennati S. Canzian d’Isonzo (GO)


Farm with 860 lactating animals. The cooling system is present in the waiting room and partially in the feeding lanes.
During 2017, cooling began in June and the animals’ response was not long in coming: average production increased by about 4 kg compared to 2016. The following year, as expected, the improvement was even greater. In addition to an increase in average production, the drop in production in the summer months was very limited: -1 kg/head/day.

Az. Agr. Bennati S. Canzian d’Isonzo (GO)


In the summer of 2017 fertility was also maintained at spring levels, with a slight drop in PR (Pregnancy Rate) values.
2018 saw a further improvement in herd fertility, benefiting from the earlier start of the cooling Program.

Az. Agr. Mori Pietole (MN)


The farm consists of 260 cows in production for Grana Padano. In May 2018 the cooling system was activated. Production in the summer months averaged 35 kg/day, while in 2017 in the same period it was 33.5 kg/day. S.S. ingestion also increased by 1.5% during the same period. The quality of the milk remained on the winter values, with a clear improvement in the fat percentage. The farm managed to maintain the Quality premium without any summer interruptions.

This is data. IMPOSSIBLE not to choose Program Elements.


The Elements Program explained by a breeder who chose it

Mantua dairy farmer Giorgio De Cao, who produces milk for Grana Padano, has chosen the Arienti cooling system – Elements Program – for his cows. And he says: their production performance remains high even in summer..

In July as in January

Giorgio De Cao explains: “Thanks to this cooling system my cows have much less problems with heat stress. As a result, we have more pregnancies in June, July and August, so the following spring we have more calvings. So the number of calvings becomes regular throughout the year and the lactation days are reduced to 165, which results in higher average milk yields. Without cooling, however, I would have 200-day lactations and therefore lower milk production.

And that’s not all, because the Mantua-based farmer adds: “Since my cows have more energy thanks to cooling, I have recorded fewer accidents, such as those linked to pubic diastasis. Furthermore, cooled cows spend less time standing and therefore more time resting, which as we know is a very productive activity”.

De Cao adopted this cooling system in 2019, starting with half of his barn. He then went on to equip the whole barn with it in 2020. “And since I have been using cooling in July, I am seeing an increase in production of around 10 quintals of milk compared to the July months before cooling”.

“In short, in July my cows offer the same milk production as in January. This increase in production fully repays the investment in this animal cooling system”.

The dairy farm run by Giorgio De Cao is part of the agricultural company F.lli De Cao s.s., located in Romanore di Borgoforte (MN). Giorgio De Cao is co-owner of the farm together with his cousins Sergio, Giovanni, Giuseppe and his father Bepi.
