Until recent times, the main concern of the farms was to obtain the highest productivity.

Economic constraints have always been clear. They were given precedence above any other idea. First, as any other business, it was a matter of greater or lower benefit.

Subsequently, a forced increase in competitiveness; attracting and defending markets because of the reduction in the number of customers ̶ although each of them was more relevant (large food chains); increasingly narrower working conditions; globalization of the sector; seeking developing countries with lower labour costs, cost transformation and means of transport that have allowed the marketing of meat and any other product from to anywhere in the world.

In the end, a situation of ‘survival strategy in the market’ arises.

In view of the above, livestock farms have used the tools allowed by the marked to defend themselves, and in that light, they have tried to do their best to increase productivity ̶ it does not mean they have increased their benefit, ̶ it was a simple matter of necessary growth to be more competitive or, in any case, to withstand market shares.

One of the main tools used to stabilize conversion rates was the palliative application of drugs in livestock when an animal became ill, mainly antibiotics, and not only this, but also the regularly use of the preventive application of these drugs in livestock in order to protect the animal beforehand against illnesses and thus to maintain a significant productivity capacity.

However, the consequences of this use have been perniciously transferred to human health. Our new generations of people have new diseases; different variants of cancer have proliferated; allergies; type 1 diabetes, etc., all of them proved by the medical population because of the many situations of acquired immunodeficiency and genetic alterations involuntary caused in people as a result of the intake of meat and agricultural products that had been manipulated seeking for higher productivity.

Both in the European Union and elsewhere, they are aware of this and they are regulating the drastic reduction of the application of drugs in animal feed, because they know where the problem is,…. From there the source of these changes. It is now when the radical turn in the market orientation is taking place …

The final consumer wants to eat a healthy product; the food chain wants to provide healthy meat to its consumer, … and the farmer is becoming aware of the need of producing healthy food, but what do they have to do if they cannot use drugs or similar means¿??

This has to be achieved by regenerating the digestive capacity, so that the animals can recover their ability to optimize the use of nutrients. This would naturally enable their productive capacity, and would protect them better against diseases through a greater stimulation of their own immune defences.

In short, in order to eat healthy meat, the animals have to be healthy, and of course this quality is not incompatible with good productivity.
