Shading net for livestock: animals suffer from excess heat. Learn how to avoid heat stress and improve production.

The shading net for livestock is an indispensable aid to reduce the temperature of zootechnical facilities, especially dairy farms.

In fact guaranteeing a temperature that allows the thermal comfort of the animals should be one of the objectives of the producers. Only in this way the animals will be prevented from suffering from excessive heat.

In addition when the temperatures are very high, organic and metabolic functions are affected and these changes can harm the health of the animals and their production.

Livestock solar stress can reduce milk and meat production so installing shaded areas for cows to rest is very advantageous

The OBAMALLA shade netting for livestock as protection from the sun’s rays

During the last century the temperature of the earth’s surface has progressively increased due to the global overheating.

In addition some areas are registering sudden changes of the temperature with negative effects on the agro-zootechnical productions.

To meet the needs of farmers and ranchers, the OBAMALLA shade cloth netting has been developed to be a barrier against the sun’s rays, while its fabric is permeable to rain and allowing adequate ventilation.

The OBAMALLA mesh avoids strong thermal excursions, achieving more constant temperature and relative humidity values.

Made of high quality polyethylene, UV treated, it resists weathering, tearing and shrinking.

It is capable to stop up to 98% of the sun’s rays.

Thermal stress in production animals

The animals are very sensitive to intense and prolonged thermal stress. Additionally, it must be remembered that animals suffer from heat before humans. Consequently extreme weather conditions can have serious consequences on their health and in particular on the production of meat and milk. Thermal stress occurs when the animal is not able to disperse heat to keep its body temperature within normal limits.

Animals respond to thermal stress differently according to age, physiological status and health conditions. When the environmental conditions exceed the critical limits and the heat produced or absorbed is greater than the dissipated the animal enters into hyperthermia. Consequently, prolonged exposure to ambient heat compromises the body’s ability to thermoregulate, causing stress, disease or even death of the animal.

leaving shaded areas in the grazing fields will allow cows to seek shelter under the hottest hours. A simple plastic shade cloth will do over any structure, or even tensed with the use of cables.


Negative effects of exposure of cattle to high temperatures

Heat is a factor of physio-metabolic changes. If the thermal stress conditions persist, welfare can be severely impaired. Respiratory and digestive pathologies are consequences of thermal stress. Also there is an increased risk of toxicosis, and the immune capabilities are reduced due to increased cortisol in the blood. One of the most immediate effects of heat is that animals reduce their food intake. It is a reaction that allows body thermoregulation as it avoids producing more heat with in the digestion process.  As part of the effort to test high temperatures, the energy that should be used for milk growth and production is intended for body thermoregulation. If the conditions of space and hygiene of the stable are also not optimum, the levels of stress can be higher.

All these factors end up having consequences on production. Particularly as regards milk cows, production is affected in both quantitative and qualitative terms. Under conditions of thermal stress, cows can produce 20% less than the average. In addition the protein content is lower. So the product value is inferior.

Applying the shading net for livestock OBAMALLA, a greater consumption of food is registered with a substantial improvement of health conditions and production.

The high temperatures also have negative effects on the quality of the meat, in terms of variations in color, tenderness, flavor and shelf life. In fact thermal stress causes alterations at the muscular level. In conclusion, the importance of preventing heat stress through the shading netting for livestock to improve the quality of the product is clearly evident.

heat stress weakens animals, so allowing animals to have a solar shelter is a great way to improve their health.


Principal problems caused by thermal stress in dairy cows


Depression of the immune system

Increased risk of pathologies such as: mastitis, metritis, prolapse of the uterus

– Metabolic disorders: for example acidosis

– Greater incidence of death of animals under conditions of prolonged and prolonged stress

– Decrease in the amount of milk produced

– Worse milk quality (loss of fat, protein and somatic cell growth)

– Reproductive problems: decreased conception rate, increased interpartum intervals

 For all the consequences on health and animal production, it is important to maintain an environment with the appropriate temperature and humidity values.

The THI – Temperature Humidity Index – is an important indicator of animal discomfort in extreme climatic conditions. This value expresses the relation between temperature and relative humidity in the environment. When THI is too high, for example, milk production is reduced. In order to avoid risk, the THI must be kept below 72 in milk cows. In beef cattle the recommended maximum THI is 78.

Beyond these values ​​animals suffer from thermal stress. We must also consider differences between livestock breeds. Some breeds are more resistant to the dispersion of the heat and have greater capacity of adaptation to the climatic changes. Generally speaking, at 80 degrees, the cow decreases food intake, at 90 milk production is affected and conception problems appear.

With very high heat, 100 degrees or more, higher mortality rates have been registered.

Tips for Avoiding Thermal Stress 

  • Install a shading system with shading netting for livestock to avoid direct contact with the sun’s rays
  • Look for an adequate amount of good quality water
  • Caring for food to make food easier to digest
  • Ensure ventilation and air circulation
  • Reduce the incidence of For this it is possible to effectively use the anti insects netting
  • Avoid overpopulation

OBAMALLA can be used to shade livestock stables, but also in other types of facilities intended for breeding pigs, goats, sheep and poultry. It can also be used in patios, terraces and gardens to lower the temperature to protect pets from excess heat. Keep cattle cool installing the shade netting for livestock OBAMALLA. Animals suffer less heat stress. Consequently, economic losses are reduced and quality of the production is maintained.

Hortomallas Hortomallas

HORTOMALLAS manufactures and markets crop support nettings (trellising and tutoring as alternatives to the raffia twine labor intensive traditional system) that increase crop quality. Our Mission is to: INCREASE VEGETABLE CROP YIELD AND PROFITABILITY TO ALL THOSE VEGETABLES THAT NEED TUTORING AND SUPPORT USING NETTING INSTEAD OF RAFFIA. Since 1994 we help professional growers and farmers improve their cucumber, tomatoes, melon, zucchini, bean, chile, peppers crops where trellises and supports are needed. HORTOMALLAS is the ideal system for cucurbitacea and solonacea to improve their phytosanitary conditions, while increasing the solar exposure and the brix degrees. Besides the obvious labor costs savings, the use of HORTOMALLAS increases the life span of the plant, allowing longer periods of harvests and of a greater quality.
