The continued use of pharmacologically active substances together with the high growth rate at which birds are subjected in industrial poultry prevents the proper development and functioning of bird´s organs.

The liver is responsible for the metabolization and synthesis of proteins, lipids and carbohydrates and the main detoxifying organ. It is one of the organs subjected to a greater effort. This over-effort does not always have clinical consequences and is sometimes manifested only with an alteration of the productive parameters.

Liver conditioner pronutrients are molecules of botanical origin capable of enhancing the physiological state of the liver and improving the renewal of hepatocytes.

1. Objective

Evaluate the effect of liver conditioner pronutrients on production parameters in broiler.

2. Material and methods

The production parameters were compared between the two experimental groups:

• Group A. Control: without liver conditioner pronutrients
• Group B. Experimental: with liver conditioner pronutrients in feed at a dose of 0.5 kg/t.

3. Results

The average weight and carcass weight, mortality, conversion rate (FCR), as well as the prevalence of liver disorders were evaluated. The results are shown below:

A significant improvement was observed in all the studied parameters. Animals treated with liver conditioner pronutrients obtained higher final weight and carcass weight. At the same time, animals treated with pronutrients consumed a lower amount of feed to reach the final weight.

The relative weight of the liver was lower in the group treated with pronutrients compared to the control group, reaching a relative weight of 24.3 g/kg of body weight and 26.9 g/kg of body weight, respectively. Similarly, the prevalence of liver disorders was significantly lower in the group treated with liver conditioner pronutrients.

The differences in mortality between the two groups studied were noteworthy. Mortality in the group without liver conditioner pronutrients was almost 50% higher than in the group treated with liver conditioner pronutrients.

4. Conclusion

The use of liver conditioning pronutrients allows to maintain an adequate physiological status of the liver, a multifunctional organ with special importance for bird’s growth.

Proof of this effect are the results obtained with respect to the relative weight of the liver. A lower weight of an organ is positively related to better organ functioning. In this case, we observed how those animals treated with liver conditioner pronutrients had a lower relative weight of the liver.

An adequate physiological status of the liver allows birds to obtain higher final weight and greater carcass weight while reducing feed consumption.

Liver conditioner pronutrients are marketed under the name Alquernat Livol from Biovet S.A.
